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，圣霖国际轧钢设备报价，使棒材表面形成马氏体**，在随后的温度**过程中，圣霖国际轧钢设备价格，芯部热量散出对表面马氏体**可产生回火作用，圣霖国际轧钢设备生产，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.

切分刀粘钢是如何引起的？（1）切分孔型老化，切分孔出来的料在切分契尖处较厚，增加了切分刀的切分负荷；（2）切分道和孔型不对中，使切分刀不能顺利切开料型，引起粘钢；（3）切分处冷却水冷却效果不好，导致粘钢；（4）料型控制不好，或有条头和开花头现象，使切分刀不能顺利切开料型。

How does the slitting tool stick to the steel?

(1) the slitting hole is aging. The cutting hole is thicker at the cut point and the cutting load is thicker. (2) the cutting section and the pass are not in the middle， so that the cutting tool can not cut the material well and cause the sticky steel. (3) the cooling effect of the cooling water is not good，圣霖国际轧钢设备， and (4) the  of the material type is not good， or there is a strip head and the flower head phenomenon， so that the cutting knife can"t go **oothly. Cut the material type.

轧钢生产的工序十分复杂，尽管随着轧制质量要求的提高，品种范围的扩大以及新技术，新设备的应用，组成工艺过程的各个工序都会有相应的变化.

The process of rolling production is very complicated. Although all the processes of the process will be changed along with the improvement of rolling quality requirements， the expansion of varieties and the application of new technology and new equipment.
