棒材穿水冷却装置的基本原理是什么？

在精轧机后设有一个由数个水冷箱组成的可调水冷段，轧钢设备哪家好，对棒材进行急剧冷却，使棒材表面形成马氏体*，在随后的温度恢复过程中，轧钢设备，芯部热量散出对表面马氏体*可产生回火作用，结果棒材表面层为回火马氏体，芯部为细粒珠光体及索氏体*。这种*结构使棒材屈服****限和韧性****，并具有良好的可焊性。

What is the basic principle of the bar water cooling device?

After the finishing mill，轧钢设备采购， there is an adjustable water cooling section of several water cooling boxes. The rod material is cooled sharply to form martensite structure. During the subsequent temperature recovery process， the heat of the core can produce tempering on the surface martensite， and the surface layer of the rod is tempered martensite， the core is fine pearlite and Soxhlet body. This structure improves the yield limit and toughness of bars， and has good solderability.

轧钢，就是在旋转的的轧辊间改变钢锭，钢坯的形状的压力加工过程。所谓轧钢工艺过程就是一系列轧钢工艺过程组合而成的加工流程。

Rolling is the process of changing the pressure of the ingot and the shape of the billet between the rotating rolls. The so-called steel rolling process is a process of combination of a series of steel rolling process.
