Abstract

PURPOSE:To rapidly and effectively kill slag foaming without occurrence of any exceptional trouble by blowing gaseous hydrocarbon against the slag on molten iron. CONSTITUTION:To the slag 6 on the molten steel 7 in a converter 5, the gaseous hydrocarbon of propan, etc., from exclusive nozzle 4 for blowing the hydrocarbon arranged in the top blowing lance 1. Further No.8 in the figure shows oxygen gas. In this case, the gaseous hydrocarbon (CnHm) generates a heat decomposition reaction (heat quantity Q is negative) as showing in the chemical formula under high temp. (about 1,300-1,800 deg.C) at the time of blowing into the converter and it is considered that the cooling effect is effective to the killing for the slag foaming. That is the gaseous hydrocarbon shows multiplier effect to kill the slag foaming with not only cooling effect caused by endothermic reaction shown in the chemical formula, but also slag reduction effect of carbon and hydrogen generated by decomposition reaction.
