Abstract

One of the most important technical requirements in modern high-speed converter steelmaking is early formation of the furnace slag. Early slag formation helps optimize conditions for the oxygen blow and facilitates thorough refining of the steel in the converter. The main factors that determine the rate of slag formation are the contents of oxides of iron and manganese in the slag, the temperature of the steel, and the conditions under which the lime is added. When converter steelmaking is done on low-silicon, low-manganese pig iron with use of a portion of the slag from the previous heat, the slag tends to form earlier and intensive decarbonization takes place as the blow proceeds in the dynamic regime. Such steelmaking is also more efficient as a whole, since it reduces the amount of silicon and manganese in the pig and shortens the heat.
