放水式土高炉当前存在的问题之一是炉缸和炉瓢侵蚀较快,过去一般的处理方法都是进行放炉(即放太平炉或正常放炉)后对炉缸和炉瓢进行修补,因此,炉子使用寿命较短一般只有20天左右。金华铁厂在十月份采用了托料热修炉缸和炉瓢后,修补时间由过去从放炉到开炉的五天左右缩短到3个小时。由于修补时间的减少,提高了炉子的寿命,相应的增加了生铁产量。托料热修炉缸和炉瓢的方法介绍如
One of the problems existing in the water-blast soil blast furnace is that the hearth and the furnace scoop erode relatively quickly. In the past, the general treatment methods were to repair the hearth and the furnace scoop after putting the furnace (that is, putting the tempering furnace or releasing the furnace normally) Therefore, the shorter furnace life is generally only about 20 days. Jinhua Ironworks in October with the care of hot stoves and furnace scoop repair, repair time from the previous furnace to open five days or so shortened to 3 hours. Due to the reduction of the repair time, the life of the furnace is increased, correspondingly the pig iron production is increased. Support hot repair furnace and furnace scoop method introduced
