The natural gas consumption for furnace systems of continuous casting and rolling line is high,so we analyze the influence factors of gas consumption from the aspects of furnace feeding,combustion principle,combustion control,natural gas energy source composition,and so on in the fusion process,so it adopted the thermal energy utilization of natural gas combustion,the optimization and controlling of key points(CO value of combustion and oxygen content of molten copper),then the waste heat utilization rate of natural gas combustion ≥55%,the utilization unit consumption of natural gas decreased to 37.27 m3/t.
