Bessemer Process

The Bessemer process uses oxygen in the blast (wind pressure up to 0.25 MPa) to oxidize the impurities of pig iron (mainly silicon and manganese) and a small amount of iron, and uses the heat released by oxidation to raise the temperature of molten steel to the requirement of steel tapping.

Steel making | PPT

4. Steel Making Steel making is the process of selective oxidization of impurities i.e.., reverse of the iron making. 1. Steel making is a refining process to necessity to the pig iron arises because it's quite impure. 2.

Steel-making processes

The Basic Bessemer process is used a great deal on the Continent for making, from a very suitable pig iron, a cheap class of steel, e.g. ship plates, structural sections. For making steel castings a modification known as a Tropenas converter is used, in which the air impinges on the surface of the metal from side tuyeres instead of from the bottom.
