圣霖轧钢设备价格-圣霖轧钢设备-圣霖国际【顾客至上】

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， the model can be divided into two types， 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.

因为四列的短圆柱轴承在外圈上是可以脱落的，所以，也可以将内圈之间安装于轧辊在辊颈上，并将外圈安装在轴承座的内部。 我们从轧钢机整个装配的过程来看，圣霖轧钢设备报价，轧钢机中轴承以及轴承座在受力的情况上都是比较良好的.

Because the four columns of short cylindrical bearings can be shedding in the outer ring， the inner ring can also be installed between the roller and the roll neck， and the outer ring is installed inside the bearing seat. In terms of the whole assembly process of rolling mills，圣霖轧钢设备价格， the bearings and bearing housings in rolling mills are relatively good in force.

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，使棒材表面形成马氏体组织，在随后的温度恢复过程中，芯部热量散出对表面马氏体组织可产生回火作用，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组织。这种组织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，圣霖轧钢设备， 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.
