热处理是提高机械产品质量的有力手段,但也是消耗能源的重要方面。据了解,95％以上的热处理设备使用电力(除冶金和重型机器制造厂外),经粗略计算,近几年我国机械工业热处理每年用电量为23.9亿度,占全机械行业用电量的27%。但目前热处理用电存在不少不合理现象,如设备负荷率低、设备的有效利用系数小、加热设备的热损失大、加热过程的无谓耗能多、工艺落后等,因此热处理节能大有潜力。
Heat treatment is a powerful tool to improve the quality of mechanical products, but also an important aspect of energy consumption. It is understood that more than 95% of the heat treatment equipment to use electricity (except for metallurgical and heavy machinery manufacturing plants), after a rough calculation, in recent years, China’s machinery industry heat treatment annual consumption of 2.39 billion degrees, accounting for the whole machinery industry electricity consumption 27%. However, there are many unreasonable phenomena in heat treatment, such as low equipment load rate, small effective utilization factor of equipment, large heat loss of heating equipment, unnecessary energy consumption in heating process, backward technology and the like, thus great potential for energy saving in heat treatment .
