摘    要：电渣重熔过程中非金属夹杂物的去除主要发生在自耗电极端头熔滴形成期以及熔滴滴落穿过熔渣层阶段。电渣重熔过程中原生夹杂物去除的同时将产生新的夹杂物,为了有效地控制电渣锭中的夹杂物,使用复合脱氧剂对自耗电极进行终脱氧,采用合理的重熔速度、熔渣的化学组成和供电制度,以及严格控制电渣炉内氧位。

Abstract: The removal of non-metallic inclusion during remelting occurred mainly in stages of formation of dropets on the consumable electrode tip and dropets falling through the slag.The dynamics viewpoint of the lager Specific Contact Area can be used to discuss it.There will produce new inclusion with the removal of original inclusion.Therefore,to effectively control inclusions in ESR ingots,compound deoxidizer should be used as the final deoxidizer,using reasonable remelting speed,composition of slag,power supply system and the oxygen potential in electroslag furnace should be strictly controlled.
