Refining (metallurgy) - Wikipedia
The pig iron was melted in a running out furnace and then run out into a trough. This process oxidised the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal, known as finers metal or refined iron…Manufacturing of steel - SlideShare,Oct 28, 2014· Process involved in manufacturing • Carbonization of COKE • Blast furnace • Basic Oxygen Steel making [BOS] • Electric arc method,•The blast furnace is a huge, steel stack lined with refractory brick. •Iron ore, coke and limestone are put into the top, and preheated air isHow Metals are Made,Slag is lighter than iron, and it’s continuously removed from the top of the furnace. Result: The product of this process is the iron alloy pig iron. It has a relatively high carbon content of around 5 percent, which makes it very brittle, and pig iron is therefore mostly useless except in the manufacture of other iron alloys, especially steel.
