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.
