对蠕墨铸铁的生产稳定性进行了研究,发现用包钢1号稀土硅铁合金配合微量锑处理渡口钒钛铁铁水制取蠕墨铸铁时,允许原铁水含硫量波动幅度宽达0.025％以上,取得了满意的结果。文内还介绍了一种有效的提高和稳定蠕化剂吸收率的蠕化处理方法——双旋涡冲熔法的试验情况。研究结果认为,采用上述蠕化剂及蠕化处理工艺后,即有可能有效地组织优质蠕铁的稳定生产。 The production stability of vermicular graphite cast iron was studied and it was found that when the vermicular graphite cast iron was made from Baotou No.1 rare earth ferrosilicon alloy and the trace antimony treated ferrocene-titan iron molten iron, the sulfur content of the original molten iron was allowed to fluctuate by more than 0.025% , Has achieved satisfactory results. The paper also introduced an effective way to improve and stabilize the creep treatment of the creep absorption rate - double whirlpool melting test method. The results show that, using the above vermiculite and vermiculite treatment process, it is possible to effectively organize the stable production of high-quality vermicular iron.
