摘要：張宣科技特材研制公司新開發(fā)H11Mo模具鋼，但電渣錠頭部的渣溝與縮孔較深，自耗電極剩余多。有必要分析電渣重熔熱封頂階段自動控制補(bǔ)縮工藝的不足，提出適合、有效的補(bǔ)縮工藝控制新方式。經(jīng)實(shí)踐驗(yàn)證，生產(chǎn)問題得以解決，切損量減少，成材率提高。

Abstract： 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.

Keywords： mold steel; electroslag ingots; shrinkage process; hot capping; slag ditch; shrinkage hole
