Jun 06, 2014· The blast furnace (BF) cast house is the working area where hot metal and liquid slag are tapped from the blast furnace and either poured into ladles (torpedo car or open top ladle) or led off for solidification (pig casting and slag granulation) or treatment (cast house desulphurization).
The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (minimills) using an electric arc furnace process.
