| 摘 要： | 利用60 t转炉研究了采用不同含铁物料及不同比例石灰石炼钢时的钢铁料消耗、氧气消耗量和煤气产生量的变化规律.研究发现：当采用铁水作为原料,渣钢和块矿作为冷却剂时,钢铁料消耗最低,仅为1072.07 kg·t-1;当采用铁水和废钢作为原料,配有磁选渣铁时,钢铁料消耗最高,达到1092.91 kg·t-1;随着石灰石加入量的增加,钢铁料消耗增加,氧耗略有降低,吨钢煤气产生量增加.研究结果为炼钢过程优化物料结构、降低生产成本提供了新的方法.

| Abstract: | The varying characteristics of steel material consumption, oxygen consumption, and converter gas volume were studied when different ferrous materials and different proportions of limestone were used in 60 t converter. The results show that when liquid steel is used as raw material and mixture of slag-steel and lump ore as coolants, the steel material consumption per ton steel is the min-imum ( only 1072. 07 kg) , and when liquid steel and scrap steel are used as raw materials and slag-iron by magnetic separation as coolant, the steel material consumption per ton steel reaches the maximum (1092. 91 kg). Meanwhile, with the increase of the amount of limestone, the steel material consumption is increased, the oxygen consumption is slightly decreased, and the gas volume is im-proved. The results will provide a new method for optimizing the material structure and reducing the production cost in steelmaking process. |
