:: Knergize :: Formation and Properties of Blast Furnace Slag

The mechanism of slag formation was established from such data. At high temperature these materials, SiO2, Al2O3, CaO, MgO and FeO, melt to form a slag. Some heat is required to melt the slag In blast furnace. Three types of slags have been identified namely, (i) Primary slag due to fusion (ii) Bosh slag and (iii) Final slag in the hearth

Dry Granulation of Blast Furnace Slag steel-360

Liquid slag produced in a blast furnace (BF)is at a temperature of around 1500?C and has a sensible heat of around 400Mcal/ton. BF slag is rich in CaO, SiO2, Al2O3, and MgO which are similar to the components of Portland cement. When this liquid BF slag is cooled fast enough then the solidified slag has a large percentage of glassy phase with high cementations activity and hence it can be used
