摘　　要：分析了影响RH浸渍管镁铬砖侵蚀速率的因素,采取了控制驱动气体流量、制定烘烤火焰标准、改变合金加入方式和提高浸渍管利用率等,使RH浸渍管正常情况下的使用炉次由78炉增加到了86炉,增加了10.25%,有效地降低了炼钢成本。The factors affecting the RH snorkel magnesia-chrome brick erosion rates were researched. By controlling argon flow rate, developing a standard baking flames, changing the order of adding alloy, improving RH snorkel utilization, the common average life of the RH snorkel has been increased from 78 heats to 86 heats, increased by 10.25%, and steelmaking costs are reduced effectively.
