一、铸造生产过程中的能耗情况 铸造生产的能耗在机械制造工厂中占全厂总能耗的30左右,1980年我国铸件平均综合单位能耗为650公斤标煤/吨铸件,而工业发达的国家仅为360—400公斤标煤/吨铸件。 铸造生产过程的能耗可概括为燃料和动力两大部分,燃料包括煤、焦、油、煤气、木柴等初级能源:动力能源则指电能,据统计,在铸铁生产中,燃料消耗约占总能耗的60—70％,其它为动力能耗,而铸钢生产中则电耗占65—75％,其它为燃料能耗,随着工业的发展,其趋势是动力能耗的比重将逐步增大。
First, the energy consumption in the casting process The energy consumption of foundry production in the machinery manufacturing plant accounts for the total energy consumption of the whole plant about 30 in 1980 China’s average consolidated unit energy consumption of 650 kg of standard coal / ton castings, and industrial Developed countries only 360-400 kg of standard coal / ton castings. The energy consumption of foundry production can be summarized as two parts of fuel and power. The fuel includes primary energy such as coal, coke, oil, gas and firewood. Power source refers to electric energy. According to statistics, in cast iron production, fuel consumption accounts for about Energy consumption of 60-70%, the other for power consumption, while the cast steel production power consumption accounted for 65-75%, the other for fuel energy consumption, with the development of industry, the trend is the proportion of power consumption will gradually Increase.
