滚牙滚丝轮采用高频表面加热淬火是一种新的工艺方法。本文将阐述高频加热淬火时加热速度、感应器规格、冷却介质对 Cr12钢的影响,内孔淬火回火对滚牙滚丝轮变形的影响,以及高频淬火后回火对滚丝轮硬度和尺寸的影响等。生产和使用证明,滚牙滚丝轮采用高频加热淬火,不仅变形小,使用寿命长,而且还能大大地缩短热处理工艺过程的时间并提高热处理车间的生产率。这种工艺方法比通常采用箱式高温电阻炉加保护箱加热淬火优越得多,已为不少工厂所应
Rolling gear rolling high-frequency surface heating quenching is a new method. This article will explain the high-frequency heating quenching heating rate, the sensor specifications, the impact of cooling medium on the Cr12 steel, quenching and tempering of the impact on the rolling gear rolling deformation, as well as the high-frequency quenching tempering roller hardness And the size of the impact. Production and use of proven, roller gear rolling high-frequency heating quenching, not only small deformation, long service life, but also can greatly shorten the heat treatment process and improve the heat treatment plant productivity. This process method than the usual box-type high temperature resistance furnace plus protection box heating Quench much better, for many factories should be
