据粗略统计,全国机械工业中,热处理生产全年用电量约为全国总发电量的1％。这还不包括不少大、中型工厂所使用的气体燃料(煤气等),以及很多中小工厂所使用的固体燃料(煤等)炉消耗的能量。与工业发达国家比较,国内热处理车间单位能量消耗竟高达3～20倍。由此可见,热处理节能具有重大的国民经济意义。改进热处理生产组织与管理,提高对热处理节能重要性的认识,是当前我国热处理节能的关键。
According to rough statistics, in the national machinery industry, the annual electricity consumption for heat treatment and production is about 1% of the country’s total generating capacity. This does not include the energy consumed by many large and medium-sized factories for gas fuels (gas, etc.) and the solid fuel (coal, etc.) furnaces used by many small and medium-sized factories. Compared with industrialized countries, domestic heat treatment plant unit energy consumption actually as high as 3 to 20 times. Thus, energy-saving heat treatment has a significant national economic significance. Improving the organization and management of heat treatment production and raising awareness of the importance of energy saving in heat treatment are the keys to energy saving in heat treatment in our country.
