摘要
为高效利用资源,充分利用低镍铬红土矿中的镍铬元素,研发了一种新型耐候钢06CuPNi1Cr2.针对转炉冶炼耐候钢过程金属液中铬元素氧化的问题,研究并讨论了冶炼温度和一氧化碳分压对脱碳保铬的影响.转炉冶炼06CuPNi1Cr2耐候钢模拟实验表明,顶吹氧气强度为3.0～3.3 m3.min-1.t-1,终点碳的质量分数为0.02%～0.05%,冶炼终点温度控制在1680～1 700℃时,脱碳保铬效果显著.
A new-type weathering steel 06CuPNi1Cr2 was developed by high-efficiently utilizing nickel and chromium in low nickel-chromium laterite ores.The influences of bath temperature and the partial pressure of carbon monoxide on decarburization and keeping chromium were studied and discussed to solve the problem of chromium oxidation in steelmaking.06CuPNi1Cr2 smelting experiments show that the effects of decarburization and keeping chromium are remarkable when the oxygen top-blowing is 3.0 to 3.3m3·min-1·t-1,the mass fraction of final carbon is 0.02% to 0.05% and the end-point smelting temperature is 1680 to 1700℃.
