iron: Production and Refining Infoplease

2021-11-19  Cast iron is made when pig iron is remelted in small cupola furnaces (similar to the blast furnace in design and operation) and poured into molds to make castings. It usually contains 2% to 6% carbon. Scrap iron or steel is often added to vary the composition. Cast iron is used extensively to make machine parts, engine cylinder blocks, stoves ...

Steelmaking Process - an overview ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

An Overview of Steelmaking Process, Global Market Size ...

Refining: Steelmaking. To make steel, refining of iron needs to be carried out. In this process, the carbon content of hot metal is lowered, usually to less than 1% by an oxidation process in a steelmaking furnace. At the same time, alloying materials are added to the furnace to attain the required chemical composition of the final product.
