This paper introduces the design of taper bore flame hardening machine, fixtures, nozzles block and the methods to determine hardening temperature and phase balancing time.
介绍了内锥孔火焰淬火机床、工装和喷头的设计以及淬火加热温度和相平衡时间的确定方法。
As the hardening temperature increases, the speed hardening and degree of the adhesive JD increase, the mechanical and adhesion performances of the adhesive systems can be further improved.
Using infrared system the apparatus of non-touching at limited-area to monitor the hardening temperature at site is produced for high-frequency induction heat treatment.
