Partial Replacement Of Lime With Limestone As A Fluxing Agent In Steelmaking Process
Abstract: Lime added as a fluxing agent in steelmaking is prepared in lime kiln by calcination of limestone. Limestone is calcined at a high temperature; however, calcined lime is cooled prior to its transportation to the steelmaking shop. In the steelmaking process, lime is again heated to a high temperature. Thus, there is a considerable loss of energy in converting limestone into lime, cooling lime for transportation, and again heating lime to a high temperature in the steel making furnace. The present disclosure provides a method for making steel where lime is partially replaced with limestone as a fluxing agent.
