摘　　要：为了提高电渣锭轧板尾部探伤质量,减少因尾部缺陷造成的废品或计划外产品,降低过程损失,从熔速、冷却等方面对电渣重熔锭尾部工艺进行了优化。新工艺在舞钢2#、3#电渣重熔炉应用后,电渣锭轧板尾部探伤缺陷率由原来的4.87%降低至1.02%,取得了较好的效果。In order to improve the quality of tail flaw detection of steel plate from ESR ingot,reduce the number of rejected products or unscheduled products due to tail defect and process losses,the tail end ESR process is optimized from melting rate,cooling and other factors.After the new process is applied on No.2 and No.3 ESR furnace of Wusteel,the tail end defect rate of Stee plate from ESR ingot decreases from 4.87%to 1.02%with a good result.
