长寿命板坯中间包的研究及应用

Research and Application of Long-life Slab Tundish

分析了限制中间包寿命的因素。采用物理模拟和现场实践结合的方法,通过调整LF炉工艺参数和中间包结构的方法提高了钢水洁净度。通过调整中间包覆盖剂和中间包工作层的方法提高了中间包渣线抗侵蚀性,从而使单个中间包寿命由22 h提升到60.67 h。

The factors limiting tundish’s life were analyzed. By combining physical simulation with field practice, the cleanliness of molten steel was improved by adjusting the process parameters of LF furnace and tundish structure. The erosion resistance of tundish slag line was improved by adjusting tundish covering agent and tundish working layer, so that the life of single tundish can be increased from 22 h to 60.67 h.
