摘　　要：介绍了35 t/h热风冲天炉的组成系统。冲天炉熔炼工艺则具有自动配料、热风供应、炉气分析、富氧送风等特点。熔炼所获得的铁液温度稳定在1 500~1 550℃,化学成分稳定,生产的灰铸铁具有良好的石墨形态。The key construction of a 35 t/h hot-blast cupola used for iron melting was introduced. The melting process features of hot-blast cupola were automatic scrap batching, hot air supply, gas analyzer. The temperature of liquid iron can be stabilized at 1 500-1 550 ℃. The composition of the liquid iron is stable. The gray cast iron has better graphite morphology.
