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 cold simulation method was used to study the erosion law of the lining of converter when smelting low carbon steel and the reasonable amount of residue and the slag splashing position of the converter bath at the time of slag splashing. The test results show that the erosion of the weld pool is the most serious. With the increase of the gun position, the erosion of the weld pool becomes serious. The erosion depth of the upper part of the weld pool is weakened while the erosion of the bottom of the weld pool is almost unchanged. Shougang Qian’an Iron and Steel Co., Ltd. 210 t converter slag splashing molten slag pool when the site of a reasonable amount of residue was 10 t, slag splash gun was 1.35 m. After optimization, the converter’s furnace age increased from 5 500 to 8 000.
