为满足高炉强化冶炼需要,并改善出铁场烟尘治理条件和减轻炉前工人的劳动强度,继首钢4号高炉成功使用铁水摆动流槽(详见本刊1989年第1期—编者注)后,1990年利用检修之机,又在首钢3号高炉出铁场上增设了铁水摆动流槽平台及相应设备和设施,用摆动流槽出铁方式取代原有5个固定铁流咀的出铁方式,取得了良好的使用效果。开炉后第二个月高炉月平均利用系数达2.52t(m~3·d)。这期间,出铁场新增各设
In order to meet the needs of blast furnace to strengthen smelting, and to improve the iron smelter dust control conditions and reduce the labor intensity of workers in front of the furnace, following the successful use of blast furnace Shougang blast furnace chute (see No. 1, 1989 - Editor’s note) In 1990, it took advantage of the overhaul machine and added a platform of molten iron swinging chute and its corresponding equipment and facilities to the blast furnace of No.3 blast furnace in Shougang Iron and Steel Company. The tapping chute was used to replace the tapping of the original five fixed iron stream nozzles Way, and achieved good results. The average utilization coefficient of the blast furnace in the second month after opening was 2.52t (m ~ 3 · d). During this period, the new additions to the yard
