Reheating furnace in steel plant

In steel plants reheating furnaces are used in hot rolling mills to heat the steel stock (Billets, blooms or slabs) to temperatures of around 1200 deg C which is suitable for plastic deformation of steel and hence for rolling in the mill. The heating process in a reheating furnace is a continuous process where the steel stock is charged at the furnace entrance, heated in the furnace and discharge at the furnace exit. Heat is transferred to the steel stock during its traverse through the furnace mainly by means of convection and radiation from the burner gases and the furnace walls.

Re-heating furnace

The charging temperature of the steel stock may range from ambient temperature to 800 deg C. The target exit temperature of the steel stock is governed by the requirement of the process of rolling which is dependent on the rolling speed, stock dimension and steel composition. Steel quality aspects put constraints on temperature gradient and surface temperature. Fuel used in these furnaces can be liquid or gaseous fuel.

The reheating furnace classification can be done in several ways. These are described below.
1. Based on the method of heating a reheating furnace can be combustion type or electric type. The combustion type furnace can be oil fired or gas fired.
2. Based on method of charging reheating furnaces can be classified as batch type or continuous type. In batch furnaces the charged material remains in a fixed position on the hearth until heated to rolling temperature while in continuous furnaces the charged material moves through the furnace and is heated to rolling temperature as it progresses through the furnace.
3. Continuous furnaces can be further classified based on the movement of steel stock inside the furnace. Based on this classification the continuous type reheating furnaces are pusher type, rotary hearth type, walking beam type, walking hearth type or roller hearth type.
4. Based on heat recovery, the reheating furnace can be either regenerative or recuperative. Presently only recuperative type of reheating furnaces are in use.

Principles of Metal Rolling

Metal rolling is one of the most important manufacturing processes in the modern world. The large majority of all metal products produced today are subject to metal rolling at one point in their manufacture. Metal rolling is often the first step in creating raw metal forms. The ingot or continuous casting is hot rolled into a bloom or a slab, these are the basic structures for the creation of a wide range of manufactured forms. Blooms typically have a square cross section of greater than 6x6 inches. Slabs are rectangular and are usually greater than 10 inches in width and more than 1.5 inches in thickness. Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot.

Most metal rolling operations are similar in that the work material is plastically deformed by compressive forces between two constantly spinning rolls. These forces act to reduce the thickness of the metal and affect its grain structure. The reduction in thickness can be measured by the difference in thickness before and after the reduction, this value is called the draft. In addition to reducing the thickness of the work, the rolls also act to feed the material as they spin in opposite directions to each other. Friction is therefore a necessary part of the rolling operation, but too much friction can be detrimental for a variety of reasons. It is essential that in a metal rolling process the level of friction between the rolls and work material is controlled, lubricants can help with this. A basic flat rolling operation is shown in figure:130, this manufacturing process is being used to reduce the thickness of a work piece.

During a metal rolling operation, the geometric shape of the work is changed but its volume remains essentially the same. The roll zone is the area over which the rolls act on the material, it is here that plastic deformation of the work occurs. An important factor in metal rolling is that due to the conservation of the volume of the material with the reduction in thickness, the metal exiting the roll zone will be moving faster than the metal entering the roll zone. The rolls themselves rotate at a constant speed, hence at some point in the roll zone the surface velocity of the rolls and that of the material are exactly the same. This is termed the no slip point. Before this point the rolls are moving faster than the material, after this point the material is moving faster than the rolls.

As a professional and experience manufacturer in China, We can give turn-key service from foundation excavation, rolling line design, equipment manufacturing, installation and debugging, technician training depending on prominent capacity of designing and manufacturing and abundant practical experience of installation.

Rebar Detailing for Construction Industry

Reinforced concrete structures, reinforced masonry structures are becoming more and more popular these days in Real Estate industry. Reinforced concrete is better than any other construction material, because concrete gives superior strength to building. Rebar detailing – also known as reinforcing bar detailing is special part of building construction which deals with reinforced concrete structures.

Rebar detailing is a process of incorporating reinforced concrete and steel reinforcement bars to make your building stronger than ever. General steel bar used with reinforced concrete in building construction is the primary goal of rebar detailing. Special care is taken of concrete due to its importance in providing better strength to building structures.

In rebar detailing, concrete and reinforcing bar are wisely used to accomplish desired tasks. Generally concrete is good at compression, but it is a bit weak when it comes to tension. To cover this drawback, rebar is used with it in order to carry tensile loads. So when rebar detailing is used, you will be getting stronger building than any other related building types.

Rebar detailing is gaining better popularity and utilization in following areas:
• Rebar detailing projects related with Roof Truss and Joint details
• Getting detailed information regarding reinforced concrete joint and slab details• Rebar detailing with Shallow, Raft and Pile foundation details• Rebar Welded, Riveted or Bolted Steel connection details

Useful application of roll forming machine

Rolling of metal sheet is the bending continually of the piece along a linear axis. This causes alteration of the original form of the sheet; it becomes deformed. The material receives progressive shaping and contouring as it passes through a pathway of rollers. This product, steel now in a thinner flat state, is part of our everyday life. From the outside metal of your car, to the roof above your head, its uses are varied. To get sheet metal to this state, roll forming takes place upon it. Different roll forming machines prepare this material for the different products it will comprise.

Steel rolling procedure:
Waste steel ----melting---- casting----mold unloading----sorting-----deliver to heating furnace----heating to 1150 degree to 1200 degree----- come out furnace----- rolling----- finished product ----packing---- sales

Task Accomplished by the Machine
Roll forming machines contain power driven bullet type rollers and the basic task accomplished by them is bending the metal sheets like creating corrugated steel sheets and plates among others. They can also roll double sheets in the time required by ordinary machines for rolling single sheets. One of the basic advantages of using the rolling machine is automating the process of rolling making it cost and energy efficient and thereby making great savings in the overhead.

Rolling Machine Components
Among the components used in the rolling machine are –
High power driven qualitative bullet rollers;
Chain and gear driven rollers,Double sheet rolling support stands, andEmergency shut off switches.
Each of the components has its own specific role in the process of building up efficient and high quality rolling machines.

Why Use Roll Forming Machine
These machines are usually deployed for fabricating rigid as well as high strength parts using different types of metals. It can be used for light metals like aluminum as well as strong metals like steel of half inch thick. Rolling machines are used to manufacture building components with metals, and other items like angles, studs, supports, C as well as U channels and the hat channels among others.

Packing of steel coils

The function of packaging is not simply only physical protection but also marketing, barrier protection, security, information, convenience and portion control. Packaging has become an integral part of manufacturing business today and therefore manufacturers have to make sure that they have the right machines that allow them to pack their goods in the right way to the market.

One of my old customer said that a steel coil mill made a very simple package of the goods, and when arrived, customer opened the package and found that the surface of coils are all wet, or even water droplets. This will affect the normal use of galvanized roll. It's really terrible. Below are some notes, according to my experience, I would like to share with everyone refer to the package of the galvanized rolls.

Packaging are divided into horizontal packaging and vertical packaging. The main difference lies in the vertical packaging with a wooden tray or iron under it, in order to make the reinforcement of coils in containers more solid. Of course, horizontal packing is also safety, because when loaded into containers, it will be reinforced by different ways. No matter horizontal or vertical, the packing of roll is same.
1. Water proofpaper
2. Steel layer
3. Straps
4. Tags/ Marks

Above all is the details for the packing, and sincerely hope it will be helpful. Indeed, whatever you choose the steel coil or steel sheet, these experiences above can be noticed, as long as you do the packaging services better, customers can satisfy with our steel products and steel prices better.

We engineer the design and supply of equipment for rolling mills on a world wide global basis. We have many strong partners world wide that have excellent manufacturing experience and capabilities for our products that give geili an incredible price advantage.

Benefits of Using steel frames

The steel industry is undoubtedly an important contributor to the economy. Most of the construction companies available in the market uses steel frame to build heavy infrastructure, and some of the main reasons owing to which steel frames is used over other types of infrastructure available in the market is its benefits which it gives to its customers.

Advantages of steel framing
Generally,building construction is finished with the help of mild steel instead of using the most powerful tool present in the market. This mild steel is very durable and strong to use, and can be used under every circumstance or for building strong infrastructure and buildings. The features of steel framing is as following:
1. Flexible, The mild steel frames can be easily bended or molded according to the comfort of the user.2. Ductility, The soft and appropriate material of the frame will not crack in extreme conditions and instead stays intact to be used for different purposes on the construction site.
3. Durable, These are very durable to use, because they can last for a longer period of time and users need not have to bear cost for replacement again and again.

Where to use steel frames?
Before the steel frames or different kinds of cladding rails are put to use, it is important to understand what their different types are and uses which can deliver the best output to the users. Following are the kind of frames which can be used;

Information on hot rolling mills and turn-key project

Induction bending is also referred to as hot rolling, but there are some differences between the two processes. Our range of hot rolling mills are extensively used for shaping large pieces of metal, such as slabs or billets. These pieces of metal are heated above their recrystallization temperature and then deformed between rollers to form thinner cross sections. The hot rolling produces thinner cross sections than cold rolling processes with the same number of stages. Hot rolling will reduce the average grain size of a metal, while maintaining an equipped micro structure.

As any Company or Individual takes on the idea of entering into the field of installing and running a hot rolling mills, the first thing they would do is take a market survey of companies who are in the business of supply designing, manufacturing, installation and commissioning of the rolling mills equipment as requirements. 

Now, this process, in commercial terms is known as Turn Key project. For e.g. If a foreign company wants to install a hot rolling mill, they would search for the companies who would manufacture/supply/install all the machinery and give them a trial production start-up. Now, not necessarily the turn key project company will be based in the same country, and hence, they have to depend upon foreign turn key project handlers for this project.

Different types of steel products

It is well known that steel products is widely used in many different areas, and there are various kinds of different types. Generally, depending on the cross sectional shape, the steel can be divided into four main categories of profiles, steel sheets, steel tubes, and metal products. Of course, every big category can own several different small categories, and the related steel prices is not the same. Most the processing of steel belongs to pressure processing, which can make steel produce plastic deformation. According to the processing temperature of steel, it can be divided into two kinds of cold rolled steel and hot rolled steel.


Steel is an iron-carbon alloy which contains carbon. The chemical composition of steel is so different, if the steel can only contain carbon steel known as carbon steel, in the actual production, in order to ensure its toughness and ductility, the carbon content is generally not more than 1.7%. And the main elements of steel except iron and carbon, it contains silicon, manganese, sulfur, phosphorus, etc. according to carbon content, it can be devided into three kinds of steel in China.
High carbon steel, generally carbon content is above 0.6%
Medium carbon steel, generally carbon content is 0.25-0.6%
Low carbon steel, carbon content is below 0.25%


The next, there are some introductions about several normal steel products, including steel plate, steel coil, galvanized steel, steel pipe, etc.

Steel Plate
Steel plate is with molten steel pouring and pressed flat-shaped steel after cooling. According to different rolling ways, steel plate can be divided into hot-rolled and cold-rolled. Generally, steel plate can used as bridge plate, boiler plate, automobile manufacturing plate, etc. And hot rolled steel plate is a very big application in the industry, which is produced by hot rolling.


Steel Coil
Steel coil, is also known as rolled steel, which is can be produced by steel hot or cold pressing. In order to facilitate storage and transport, steel coil usually can be processed plate or strip, etc. Steel coil is divided into hot rolled coil and cold rolled coil, and the hot rolled coil is processing products which is in the front of the billet recrystallization, and cold rolled is subsequent processing after hot-rolled-coil. In order to enhance the resistance to corrosion of steel, you can use galvanized steel coil.

Advantage and importance of investment casting

Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques. 

Investment casting can make use of most metals, most commonly using aluminum alloys, bronze alloys, magnesium alloys, cast iron, stainless steel, and tool steel. This process is beneficial for casting metals with high melting temperatures that can not be molded in plaster or metal. Parts that are typically made by investment casting include those with complex geometry such as turbine blades or firearm components. High temperature applications are also common, which includes parts for the automotive, aircraft, and military industries. The process is generally used for small castings, but has been used to produce complete aircraft door frames, steel castings.
