铸造生产过程中耗用的能量较之其它专业大许多,其中很多能量利用率较低,在工艺过程中而释放。因此,如能通过工艺、技术、管理等方面措施提高能量的利用率或充分回收可利用的能量,对节能有重要意义。据调查,各厂能耗的构成均有差异,按铸铁生产分析,结果是:煤30～32％,焦30～35％电33～38％、燃油2％;或煤气12～30％、焦35～46％、电15～25％。与国外报道相比,能耗要高出30～40％,而国外在采暖、照明、通 The energy used in foundry production is much greater than in many other professions, many of which are less energy efficient and are released during the process. Therefore, energy saving can be of great significance if measures such as technology, technology and management improve the utilization of energy or fully recover the available energy. According to the survey, the energy consumption of each plant are different, according to the analysis of cast iron production, the result is: coal 30 to 32%, coke 30 to 35% 33 to 38% electricity, fuel 2%; or gas 12 to 30% 35 ~ 46%, electricity 15 ~ 25%. Compared with foreign reports, energy consumption should be higher than 30 to 40%, while foreign heating, lighting, communication
