摘要
利用冷态模拟方法研究了转炉冶炼低碳钢时炉衬的侵蚀规律和溅渣时转炉熔池部位的合理留渣量和溅渣枪位。试验结果表明:熔池部分的冲刷侵蚀最严重;随着枪位的升高,熔池部分侵蚀变得严重,熔池以上部分的侵蚀深度却减弱,炉底部分侵蚀基本不变。首钢迁安钢铁有限责任公司210 t转炉溅渣时熔池部位的合理留渣量为10 t,溅渣枪位为1.35 m。优化后,转炉炉龄从5 500炉提高到8 000炉。
The law of lining erosion and proper remaining slag and lance position of slag splash in the bath of BOF slag splashing are studied by way of water model simulation in refining the low carbon steel. Results show that the most serious washing erosion oc- curs in the portion of the bath and the erosion of the lining turns to be more and more serious with the rise of the lance position and the erosion depth in the upper portion of the bath is weakened and erosion at the bottom of the converter remains intact. In Shougang Qian＇an Iron and Steel Co. , Ltd. , the proper remaining slag amount is 10 t and the slag splashing lance position is 1.35 m. Since optimization the BOF campaign life rises to 8 000 heats from the original 5 500 heats.
