Introduction to Steel Casting Process in India

Steel casting is the complicated process of casting all kinds of different steel. The complete procedure of steel casting involves melting the steel, creating molds and cores and finally cleaning the castings and heating them. Mostly the need to use steel castings results when cast irons do not provide sufficient strength or shock resistance. Through steel casting, one can obtain small yet complex machine shapes there removing the need for wielding, assembling and other finishing work.

Steel castings are used in different kinds of industries such as transportation, general industry, construction, energy and marine. Ideally these kind of casting are constructed from low temperature steel, low and high alloy steel and heat resistant steel. Since they happen to be more powerful and stronger than cast iron or malleable iron therefore they are extensively utilized in the manufacture of complex parts where it is required to resist shocks or heavy load.

The making of steel casting goes through a number of processes, among which the first one is about creating core. Cores are usually made from a combination of sand with a chemical binder system. A series of complex cores can be convened from a variety of smaller cores. Once the core has been made, the next step in process includes melting of the steel in the furnace that ideally uses three electrodes where each provides 6,500 amps of electricity. Once the metal is melted as per the specifications, it is then undergoes a process of being poured into the right kind of molds. The mold is cooled and then broken up and the sand from the mold is then used for molding. Steel casting molds are ideally created by combining sand with a chemical binder system. The process is molding is known as Nobake or Airset System. Finally the steel castings are given a finishing touch at the cleaning room, where they are fine tuned to suit with the specifications of the customer.
