Tundish for Continuous casting machine

Continuous casting is a method of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a CC machine.

To transfer liquid steel from a teeming ladle to the continuous casting machine mould, an intermediate vessel, called a tundish, is used. 

The continuous casting tundish serves as a buffer and links the discontinuous process of the secondary steel making in the ladle with the continuous casting process in the mould. It acts as a reservoir during the ladle change periods and continues to supply liquid steel to the mould when incoming liquid steel is stopped, making sequential casting by a number of ladles possible.

Many steel plant operators have studied their tundishes in order to maximize the benefits of the residence time available for the floatation and assimilation of reaction products from the liquid steel into the slag phase. These can be products of deoxidation, reoxidation, precipitation, emulsification and/or entrainment of refractory components into the liquid steel, and thus encompass both indigenous and exogenous inclusions. Based on a sound choice of tundish design, the operation of a tundish needs to be geared to the following.

• To promote inclusion floatation by maximizing residence time

• To ensure inclusion assimilation by a captive and noncorrosive slag

• To reduce thermal and chemical losses from the liquid steel

• To minimize short circuiting and dead zones

• To offer the operator an optimal design for quality and yield.

Steel ladle for continuous casting machine

In a foundry, casting steel ladle is important device in steel making. It used for pouring operations, after receiving the liquid metal in the blast furnace, transported by road to the mold at the pouring.Ladles range in size from small hand carried vessels that resemble a kitchen ladle and hold 20 kilograms (44 lb) to large steelmill ladles that hold up to 300 tonnes (330 tons). Many non-ferrous foundries also use ceramic crucibles for transporting and pouring molten metal and will also refer to these as ladles.

The most common shape for a ladle is a vertical cone, but other shapes are possible. Having a tapered cone as the shell adds strength and rigidity to the shell. Having the taper also helps when it comes time to remove the refractory lining. However straight sided shells are also fabricated as are other shapes.

Features:
1.Resistance to burning hot metal ladle.
2.Multi-purpose hot metal ladle.
3.Safe and reliable design.
4.Easy control.

Induction Melting Furnace for Steel making

Induction furnace is the device converting three phase power current into single phase intermediate frequency current and enabling metal to produce eddy current loss through electromagnetic field induction to achieve heating and melting and is applicable to melting, heating or holding of steel, copper, iron, aluminum, zinc, tin, nickel silver and other ferrous or nonferrous metal and alloy material as well as heating treatment prior to forging, sintering and tube-bending forming in casting and melting industries. 

Performances and features
1) Using a zero-voltage scanning soft-start mode, in any case may at any time to start or stop, will not have impact on power supply.
2) Fast smelting with low production cost; low-pollution and environment-friendly;
3) A direct effect from the cold furnace melting. Dissolved material will be fully dumped clean. Molten material is easy to replace.

High Speed Steel Bar Production Line

Steel rolling consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions and so spaced that the distance between them is somewhat less than the thickness of the section entering them. In these conditions, the rolls grip the material and deliver it reduced in thickness, increased in length and probably somewhat increased in width. This is one of the most widely used processes among all the metal working processes.

Today we are want to show you is a bar production line. This production line can realize a metal rolling process from billet to steel products

Types of Carbon steels

As a group carbon steels are the most frequently produced and used steels. More than 85 % of the steels produced presently are carbon steels. Normally carbon steels contain up to 2 % total alloying elements and can be sub divided into ultra low carbon, low carbon, medium carbon, high carbon and ultra high carbon steels. These steels are described below.

Ultra low carbon steels – These steels contain very low carbon usually less than 0.10 %. These steels also contain very low manganese and very low silicon. These steels are having extra deep drawing properties and usually produced in the form of flat and wire rod products.

Low carbon steels – These steels contain up to 0.30 % C. This category includes mild steel with carbon content usually in the range of 0.15-0.30%. The largest category of this class of steel is flat rolled products in the form of sheet or strip usually in the cold rolled and annealed condition. The carbon content for these deep drawing quality steels is around 0.10 % C, with up to 0.5 % manganese. For structural use produced in the form of plates and sections, the carbon content may be increased up to 0.30 %, with higher manganese content up to 1.6 %.

Medium-carbon steels – These steels are similar to low carbon steels except that the carbon content in these steels are higher and normally in the range of 0.31% to 0.60 % and the manganese from 0.60 % to 1.65 %. Due to Increased carbon content, the medium carbon steels can be used in the quenched and tempered condition. The medium carbon steels are used as shafts, axles, gears, crankshafts, couplings and forgings. Steels in the 0.40 % to 0.60 % C range are also used for rails, railway wheels and rail axles.

High carbon steels – These steels have carbon content ranging from 0.61 % to 1.00% with manganese content ranging from 0.30 % to 0.90 %. The use of high carbon steels includes in springs, pre stressed concrete wires and high strength wires etc.

Ultrahigh carbon steels – These steels contains carbon in the range of 1.25 % to 2.0 %.  These steels are normally thermo-mechanically processed to produce microstructures consisting of ultra-fine, equi-axed grains of spherical, discontinuous pro-eutectoid carbide particles.
