热处理的能量消耗在机械行业中占很大比重,一般为四分之一左右。为了节约能源,近年来在新型绝热材料的推广应用和淬火工艺的改进等方面,已取得了明显效果。回火是热处理工艺过程中周期长、能耗大的工序,这方面的节能潜力很大。我们应该重视回火的节能措施,积极试验和应用节能的回火新工艺。 Heat treatment of energy consumption in the machinery industry accounts for a large proportion, usually about a quarter. In order to save energy, in recent years in the promotion and application of new insulation materials and quenching process improvements, has achieved remarkable results. Tempering is a long process in the heat treatment process, energy consumption of large processes, energy saving in this area has great potential. We should pay attention to the energy-saving measures of tempering, and actively test and apply energy-saving tempering new technology.
