开炉是高炉操作中最重要环节,它对高炉一代正常生产和使用寿命有着重大影响。开炉好的标志是:①焦比低;②炉况顺行,③迅速转入正常生产,④安全不出号外铁,⑤铁口易开。我厂从1964年改用焦炭开炉方法,经多次生产实践,摸索对烘炉,装料方法,配料计算某些参数的确定,如何防止焦炭开炉易产生悬料,以及开炉初期实际炉渣碱度(cao/sio_2)
Blast furnace blast furnace operation is the most important part of its normal production and life of the blast furnace has a significant impact. Open a good sign is: ① low coke ratio; ② furnace conditions go straight, ③ quickly transferred to normal production, ④ safety number not outside the iron, ⑤ iron mouth easy to open. I plant from 1964 to switch to coke oven method, after many production practices, groping for the oven, charging method, the ingredients to determine the calculation of certain parameters, how to prevent coke open furnace easily produce suspended material, as well as the initial opening of the actual Basicity of slag (cao / sio_2)
