一、前言 电冲转的混合工艺,不但解决了转炉落渣引起回磷;降低脱硫效果的问题。而且电冲转时渣温高,渣流动性好,生产调度方便,化学成分稳定等优点,从大连钢厂试验的结果来看,脱硫率,脱氧率,钢中夹杂,钢中气体,低倍和机械性能都达到了电炉钢的水平。这种混合工艺,对我国电炉一般在5～15吨,转炉一般在6～12吨来说,是切实可行的。 I. INTRODUCTION Electro-impulse mixing process not only solves the problems of phosphorus removal caused by slag drop in converter, but also reduces desulfurization effect. In addition, the slag temperature is high, the slag fluidity is good, the production scheduling is convenient and the chemical composition is stable. According to the test results of the Dalian steel mill, the desulfurization rate, the deoxidation rate, the inclusions in the steel, the gas in the steel, And the mechanical properties have reached the level of EAF steel. This mixing process, the electric furnace in China is generally 5 to 15 tons, the converter is generally 6 to 12 tons, it is feasible.
