几年来,我们积极贯彻三结合精神,通过不断的摸索改进,根据高速钢热处理工艺中的850℃预热、1290℃加热及600℃等温冷却等工序,设计了一台升降式联合淬火机。使用一年多来,比较满意。现将它的结构简介如下,以供参考。一、工作原理和主要参数 Over the past few years, we actively implement the spirit of the three combinations, through continuous exploration and improvement, according to the high-speed steel heat treatment process 850 ℃ preheating, 1290 ℃ heating and 600 ℃ isothermal cooling process, designed a lifting combined quenching machine. Use more than a year, more satisfied. Now its structure is as follows, for reference. First, the working principle and the main parameters
