冲天炉是各铸工间里应用最广的熔化设备.在全国范围内,这些冲天炉中每年要熔化大量生铁,因此也要消耗大量的焦炭、耐火材料以及上千百万工时的劳动力.由此可以看出,在冲天炉中化铁所要消耗的燃料、耐火材料和劳动力是如何庞大,同时也说明应该引起铸工车间工作人员的特别重视. Cupola is the most widely used melting equipment among castors, and these cupola melts every year throughout the world, so it consumes a lot of coke, refractory materials and tens of millions of man-hours of workforce. It can be seen how large amounts of fuel, refractory and labor are consumed by the iron in the cupola, and at the same time, should give particular attention to the staff in the casters.
