Model of Inclusion Evolution During Calcium Treatment in the …

2018/4/24· Calcium treatment of steel is typically employed to modify alumina inclusions to liquid calcium aluminates. However, injected calcium also reacts with the dissolved sulfur to form calcium sulfide. The current work aims to develop a kinetic model for the evolution of oxide and sulfide inclusions in Al-killed alloyed steel during Ca treatment in the ladle refining process. The model considers

The chemistry of steelmaking. Acids and bases.

Calcium oxide also plays an important part in the Basic Oxygen Steelmaking furnace.Here it helps to remove impurities such as phosphorus and sulphur from the steel. Phosphorus is a non-metal and produces an acidic oxide, P 2 O 5.In the BOS furnace P 2 O 5 coines with the basic calcium oxide to make calcium phosphate.
