摘　　要：张宣科技特材研制公司新开发H11Mo模具钢,但电渣锭头部的渣沟与缩孔较深,自耗电极剩余多。有必要分析电渣重熔热封顶阶段自动控制补缩工艺的不足,提出适合、有效的补缩工艺控制新方式。经实践验证,生产问题得以解决,切损量减少,成材率提高。Zhangxuan Technology Special Materials Company has newly developed H11Mo mold steel,but the slag groove and shrinkage hole at the head of the electroslag ingot are deeper,leaving more consumable electrodes.It is necessary to analyze the shortcomings of the automatic control shrinkage process during the hot capping stage of electroslag remelting,and propose a suitable and effective new method for shrinkage process control.Through practical verification,production problems have been solved,cutting loss has been reduced,and yield has been improved.
