在林业机械中,有一些要求表面耐磨、而又不易用常规热处理手段处理的大型零件。例如制材机械中的带锯机带锯上下轮,纤维板机械中的热压机柱塞,装卸板机油缸缸心等。用高频淬火、整体淬火、火焰表面淬火,需要大型设备,工艺复杂,零件选材严格,一般生产单位不易做到,也不经济。而采用电接触加热表面淬火的热处理工艺,则容易解决上述问题,达到硬化零件表面的目的。
In forestry machinery, there are some large parts that require surface wear but are not easily handled by conventional heat treatment. For example, in the sawing machine band sawing machine up and down the wheel, fiberboard machinery in the hot press plunger, loading and unloading machine cylinder cylinder heart. With high-frequency quenching, the overall quenching, the flame surface quenching, the need for large equipment, complex technology, strict selection of parts, the general production unit is not easy to do, not economical. The use of electrical contact heating surface hardening heat treatment process, it is easy to solve the above problems, to achieve the purpose of hardening the surface of the parts.
