济钢1号1750m3高炉炉前通过对全液压开口机进行改造,对分体钻杆、弧形整体连接套、雾化水系统的深入研究,将炉前钻杆的消耗从1.4根/炉次降低到了0.45根/炉次、钻头消耗量从2.1个/炉次降低到了1.1个/炉次、打开铁口时间由原来的平均20min降低到了10min,极大地降低了炉前消耗、缩短了开铁口时间、减少了操作人员的劳动强度。
Jinan Iron and Steel 1 1750m3 blast furnace through the hydraulic opening machine to transform the split drill pipe, the overall arc sleeve connection, atomized water system in-depth study, the consumption of the drill pipe before the fire from 1.4 / furnace Reduced to 0.45 / furnace, bit consumption reduced from 2.1 / furnace to 1.1 / furnace, opening the iron mouth time from the average of 20min reduced to 10min, which greatly reduces the consumption of the furnace, shorten the open iron Mouth time, reducing the labor intensity of the operator.
