post-treatment finishing(During laser hardening treatment heat is concentrated intensely at the surface, little distortion takes place-which means that minimal post-treatment finishing is required. 激光硬化处理时，热量高度集中于表面，工件变形量很小，这就意味着所需要的后续精整处理量也很小。)
regulation of roll(All the sequences of operations, the tracking of the coil of strip, and the regulation of the rolls are computer-controlled, while closed circuit TV is used to assist supervision. 所有操作程序、带卷跟踪和轧辊调整均由计算机控制，同时还使用闭路电视协助监控。)
