摘要

针对某钢厂弹簧钢精炼过程中各种夹杂物去除率不理想的问题，提出了进口流量比为2:1的等流量底吹方法，并通过数值模拟和实际生产验证了该方法的有效性。数值模拟结果表明:2:1底吹方式下，钢液具有较大的轴向流动强度，有利于夹杂物向渣层漂浮;2:1底吹法对夹杂物的去除率比等流量高8%左右。生产结果与数值模拟结果一致，当进口流量为100 NL/min时，2:1底吹方式下的夹杂物去除率比等流量时提高约18%，同时夹杂物总数和大尺寸夹杂物均低于等流量。

Numerical simulation on inclusion removal behaviours in refining processes of spring steel

ABSTRACT Aiming at the unsatisfactory removal rate of various inclusions in refining process of spring steel in a steel plant, this study proposes a unequal flow bottom blowing method with an inlet flow ratio of 2:1, and its effectiveness is verified by numerical simulation and actual production. The numerical simulation results show that under the 2:1 bottom blowing method, the molten steel has greater axial flow strength, which is conducive to the inclusion floating to the slag layer. The removal rate of inclusions under the 2:1 bottom blowing method is about 8% higher than that of the equal flow. The production results are consistent with the numerical simulation, when the inlet flow is 100 NL/min, the inclusion removal rate under 2:1 bottom blowing method is about 18% higher than that of equal flow, meanwhile, the total number of inclusions and large size inclusions are lower than that of equal flow.
