铸造工业是耗能较多的一个部门。据统计,西德在1977年铸造工业共消耗140万吨标准煤燃料。根据每生产一吨合格铸件所需的能量消耗分析(见表1),生产各种铸件的能量利用率很低,其中,球墨铸铁的能量利用率只有15～35%。法国对铸铁车间所需的能源种类、用途及能源组成进行了统计分析(见表2)。 Casting industry is a department that consumes more energy. According to statistics, West Germany foundry industry in 1977 consumed 1.4 million tons of standard coal fuel. Based on the energy consumption analysis required to produce one ton of qualified castings (see Table 1), the energy utilization for producing the various castings is very low, of which the energy utilization of ductile iron is only 15-35%. France conducted a statistical analysis of the type of energy, its use and energy composition required for the cast iron workshop (see Table 2).
