热处理是大量消费能源的工业部门,但长期来热处理部门很少认真考虑节能问题。本文综合了十种节能热处理方法,一般都是在原有基础上,利用现有设备,对热处理工艺稍作调整,从而达到显著的节能效果,现介绍如下。一、调质代替球化退火高碳钢一般在淬火低温回火前,要进行球化退火,建议采用调质代替球化退火。例如T8钢冷冲冲头:采用880℃加热、水淬油冷,560℃回火两小时,再经淬火
Heat treatment is a heavy industrial sector that consumes energy, but the heat treatment sector seldom seriously considers energy saving for a long time. This article combines ten energy-saving heat treatment methods are generally based on the original, the use of existing equipment, a slight heat treatment process to adjust, so as to achieve significant energy savings, are presented below. First, the quenched and tempered instead of high-carbon steel annealing In general, quenching low-temperature tempering, to the ball annealing, the proposed quenched and tempered instead of ball annealing. For example, T8 steel cold punching head: the use of 880 ℃ heating, oil quenching oil, 560 ℃ tempering two hours, and then quenched
