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，对棒材进行急剧冷却，设备安装厂，使棒材表面形成马氏体***，在随后的温度***过程中，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***结构使棒材屈服极限和韧性提高，并具有良好的可焊性。

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

After the finishing mill， 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.

钢的轧制，是整个轧钢生产过程的核心。坯料通过轧制完成变形过程。轧制工序对产品质量起着决定性作用。轧制产品的质量要求，包括产品的几何形状和尺寸内部***和性能以及产品光洁度三个方面。

The rolling of steel is the core of the whole rolling process. The blanks are rolled to complete the deformation process. The rolling process plays a decisive role in the quality of the product. The quality requirements of rolling products include three aspects，设备安装报价， including the internal structure and performance of the geometric and dimensional accuracy of the products and the finish of the products.

单就冷轧机的轧制速度而言，其型号就可分为两种，一种是每秒线速度在3米的冷轧机，还有一种则是线速度在20米冷轧机，后面这一种设备已经可以算得上是***快的了。

As far as the rolling speed of the cold rolling mill is concerned，设备安装厂家， the model can be divided into two types，设备安装， one is a cold rolling mill with a line speed of 3 meters per second， and one is the line speed in the 20 meter cold rolling mill， and the latter is the fastest.
