Steel casting

Steel casting is a specialized form of casting involving various types of steels. Steel castings are used when cast irons cannot deliver enough strength or shock resistance. A steel casting is the product formed by pouring liquid steel into a mould cavity. The liquid steel cools and solidifies in the mould cavity and is then removed for cleaning. Heat treatment may be needed to meet desired properties. This process provides the near net shape and mechanical properties required for meeting the specifications.

The making of a steel casting is a long and complex process. A large investment in capital equipment is required for the melting of steel, manufacturing of cores and moulds and the cleaning and heat treating of castings. Additional major investments for support equipment and facilities are required for sand reclamation systems, dust collection devices and bulk material handling systems etc.

Steel castings are used for vitally important components in the mining, railways, automotive, construction, military, and various industries including oil and gas industries. Steel castings are specified for applications which require weldability, abrasion resistance, high strength, low and high temperature service and corrosion resistance. Though there are large numbers of steel foundries, yet due to the diversity of market requirements such as size, tolerances, chemistry, volume, etc., a single foundry cannot serve all of the market and each foundry tends to specialize in a portion of the total market. Some of the specialized areas are (i) railways, construction equipment, and truck and mining industries, and (ii) high alloy stainless steel used in corrosion and heat resistant applications or low volume prototype and service parts. Examples of items which are produced in the form of steel castings include (i) hydroelectric turbine wheels, forging presses, gears, railway wagon frames, valve bodies, pump casings, mining machinery, marine equipments, turbocharger turbines, and engine cylinder blocks etc.

Continuous casting machine

Main equipments of Continuous Casting Machine

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Liquid steel is usually cast in continuous casting machines in the shape of billets, blooms, or slabs. In some plants, it is also being cast in continuous casting machines in the shape of thin slabs or dog bone sections. 

Continuous casting machine is mainly composed of pouring equipment, continuous casting machine ontology, cutting device, dummy bar collection and transportation equipments. the components are as below:

Components:

• Turret charter
• Tundish
• Overflow tank
• Console frame of revolving operation box
• Tundish car
• Mould

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. It includes pouriong equipment, major equipment, cutting area equipment, dummy bar collection and transmission equipment. Nowadays, continuous casting" has evolved to achieve improved yield, quality, productivity and cost efficiency. This process is used most frequently to cast steel (in terms of tonnage cast). Aluminium and copper are also continuously cast.

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.

Advantage:
1. Many Intricate forms with undercuts can be cast.
2. A very smooth surface is obtained with no parting line.
3. Dimensional accuracy is good.
4. Certain unmachinable parts can be cast to preplanned shape.
5. It may be used to replace die-casting where short runs are involved.
