摘　　要：以首秦公司加热炉为研究对象,根据能量守恒定律及回归分析方法建立了入炉钢坯温度与高炉煤气燃耗的关系模型,并通过现场试验加以验证。研究表明,钢坯入炉温度和热装率是加热炉燃耗的重要影响因素,在加热炉热装率较高情况下,提高热装温度对降低高炉煤气燃耗效果较为明显;加热炉钢坯热装试验验证了所建立的分析模型的正确性,为加热炉能耗分析提供了理论依据。The empirical formula of billet hot charging and blast furnace gas （BFG） burn-up is established by the law of conservation of energy and corresponding mathematical methods in the research object of heating furnace of Shouqin Compa- ny. The research results are checked with field experiment. The results show that billet is important influential factors of heating furnace burn-up. When the hot charging of heating furnace is at the high ratio level, the reduction of BFG burn-up is more obvious with increasing hot charging temperature. The establishment of empirical formula and the analysis of the effects of billet hot charging supply the theory basis for furnace energy consumption analysis.
