【摘要】 本文对锰元素在转炉内的反应机理进行了热力学分析,计算出转炉吹炼不同阶段锰元素的平衡浓度,并通过理论计算与实际生产数据进行对比,确定了转炉吹炼终点锰元素的化学平衡形式。利用方差分析、回归分析等方法,建立了转炉单渣冶炼工艺终点锰含量的回归方程;对于转炉双渣冶炼工艺,明确了半钢碳含量及转炉终点碳含量对半钢脱锰率及转炉终点锰含量的影响规律。更多还原

【Abstract】 In this article, thermo-mechanical analysis was done on the reaction mechanism of manganese in the converter and equilibrium concentration at different blowing stages in converter was calculated. Through comparison of theoretical calculation and actual manufacturing data, the chemical equilibrium form of manganese was determined at the end-point in converter. Using methods of variance analysis and regression analysis, etc, regression equation was established. And aiming at double-slag smelting technology, affection rule of semi-steel carbon content and converter end-point carbon content on semi-steel manganese removal rate and end-point manganese content was illustrated.更多还原
