通过试验并结合生产实践,对转炉滑板挡渣机构内、外部耐材的使用寿命进行了统计和分析,同时对内部耐材进行了成分改良,进一步提高了滑板挡渣机构的在线使用寿命,为滑板挡渣机构离线维护工作量的减少和滑板挡渣机构在线更换次数的降低提供了有利支撑,对国内各大钢厂正在推广使用的转炉滑板挡渣法具有很好的推广价值。 Through the experiment and combined with the production practice, the service life of the refractory inside and outside of the skid steer in the converter was calculated and analyzed. At the same time, the internal refractories were improved and the online service life of the skid steer was further improved Skateboard slag removal mechanism to reduce the workload of offline maintenance and skateboard slag online replacement mechanism to reduce the number of available to provide favorable support for the major domestic steel mills are promoting the use of the converter skateboard slag method has a good promotional value.
