摘要

摘要: 利用60 t轉爐研究了采用不同含鐵物料及不同比例石灰石煉鋼時的鋼鐵料消耗、氧氣消耗量和煤氣產生量的變化規律.研究發現:當采用鐵水作為原料,渣鋼和塊礦作為冷卻劑時,鋼鐵料消耗最低,僅為1072.07 kg·t^-1;當采用鐵水和廢鋼作為原料,配有磁選渣鐵時,鋼鐵料消耗最高,達到1092.91 kg·t^-1;隨著石灰石加入量的增加,鋼鐵料消耗增加,氧耗略有降低,噸鋼煤氣產生量增加.研究結果為煉鋼過程優化物料結構、降低生產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.
