电弧加热冒口(EAHT)在铸钢轧辊生产中的应用

在三强铸钢厂 ,应用电弧加热冒口技术 ,已有效地减少了铸钢轧辊中所存在的各类内部缺陷 ,同时还提高了钢水的收得率。 1 993年 ,EAHT轧辊毛坯的一次合格率达96%以上 ,最终冒口重量的比率在 2 .5%～ 4.0 %之间 ,取得了良好的质量效应和经济效益。在应用 EAHT工艺的过程中 ,实现工艺参数的最佳配合是工艺成功的关键因数之一。建议应采取协调措施 ,在铸钢轧辊生产行业中大力推广 EAHT技术。

The Application of Electric Arc Heating Top in Steel Casting Roll Production

In SANQIANG Steel Casting Foundry,by means of the application of electric arc heating Top process (EAHT),the various internal defects in steel casting roll are effectively reduced,and at the same time the steel utilization ratio is raised.In 1993,the primary percent of pass of the EAET roll blank was more than 96%,the final riser weight ratio was 2.5～4.0%,the good mass effect and commercial efficiency were gained.In the course of the application of the EAHT process,the optimum coordination of technological parameters is one of the key factors for success.We ought to take the coordinative measures so as to energetically spread the EAHT process in the production trades for steel casting rolls.
