摘　　要：为提高钢包自开率,分析了引流砂质量、出钢温度、钢水在钢包内停留时间和热修操作对钢包自开率的影响。结果表明,通过调整引流砂的成分配比及粒度分布,严格将水分含量控制在0.2%以下,出钢温度在1580~1620℃、钢水在钢包内停留时间在90 min以内,并进一步加强钢包的日常管理,可使钢包自开率稳定控制在98%以上。In order to improve the ladle opening rate,the effects of drainage sand quality,tapping temperature,residence time of molten steel in ladle and hot repair operation on ladle opening rate are analyzed.The results show that by adjusting the composition ratio and particle size distribution of the drainage sand,controlling the moisture content below 0.2%,tapping temperature 1580~1620℃and the molten steel in the ladle within 90 minutes,further strengthening the daily management of the ladle,the ladle self opening rate can be stably controlled above 98%.
