摘　　要：闪速炉在强化熔炼时会出现因熔体中Fe_(3)O_(4)含量过高而造成的炉膛粘结、渣含铜高等问题。针对这一问题,对控制中间产物继续过氧化、加入还原剂进行Fe_(3)O_(4)造渣反应进行过程分析,有效的减少了闪速炉炉膛粘结,保障了熔炼过程的顺利进行。The problems of furnace adhesion and high copper content in slag caused by high content of Fe_(3)O_(4)in the melt will occur in the flash furnace during intensified melting.In order to solve this problem,the process analysis of controlling the intermediate products to continue peroxide and adding reducing agent for Fe_(3)O_(4)slagging reaction was carried out,which effectively reduced the furnace adhesion of flash furnace and ensured the smooth progress of smelting process.
