The 3m tons integrated steel plant produces both blast furnace slag and steel slag. The blast furnace slag after granulation, is consumed by the neighbouring Indorama Cement Ltd, in the manufacture of Portland Slag cement and GGBFS conforming to BS-6699. The steel slag after crushing is partly recycled through a sintering plant.
Stabilization of Stainless Steel Slag via Air Granulation
In stainless steel production, slag from argon oxygen decarburization (AOD) converters is dumped on to the ground and then slowly cooled. The slag undergoes phase transformation from β-dicalcium silicate (β-C2S) to γ-dicalcium silicate (γ-C2S) at approximately 500 °C to 450 °C, resulting in slag volume expansion, disintegration, and …
