一、概况研究机械工业自身的节能途径时,铸造部门是一个能耗的大户。在我国机械工业的构成中,铸造行业的能耗约占机械工业总能耗的25～30%左右。为此,搞清我国当前铸造工业的能耗状况,全面分析其节能潜力与途径是十分重要的。1980年我国铸件总产量约500万吨,其中铸铁件约占85%左右。把生产过程中所消耗的燃料与动力按标准煤折算:1980年我国灰铸铁件生产的综合单位能耗为550～650公斤标煤/吨 I. Overview Research machinery industry’s own energy-saving ways, the casting sector is a major energy consumption. In the composition of China’s machinery industry, the energy consumption of the foundry industry accounts for about 25 ~ 30% of the total energy consumption of the machinery industry. Therefore, it is very important to find out the current situation of energy consumption of foundry industry in our country and to analyze its energy saving potential and ways. In 1980, China’s total output of castings was about 5 million tons, of which castings accounted for about 85%. The fuel consumed in the production process and power conversion according to the standard coal: 1980 gray iron production in China consolidated unit energy consumption of 550 to 650 kg standard coal / ton
