精整，是轧钢生产过程中***后一个工序，也是较为复杂的一个工序。实现自动化，可以提供质量好，性能稳定，价格合理的产品，为企业生产发展提供更大的空间。他对产品的质量起着***终的保证作用。产品的技术要求不同，精整工序的内容也不大相同。精整的工序通常又包括钢材的卷取，轧后冷却，矫直，成品热处理，成品表面清理以及各种涂色等许多具体工序。
Finishing is the last process in the steel rolling process, and it is also a more complicated process. He has a final guarantee of the quality of the product. The technical requirements of the product are different, and the content of the finishing process is not the same. The finishing process usually includes steel coiling, cooling, straightening products, heat treatment, surface cleaning products and various color and many other specific processes.
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***，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***。对于型钢，轧件在孔型中轧制，并且在每个孔型中轧制一道，因此，型钢的变形制度是以孔型的形式表示的，孔型的设计确定后变形制度就确定了。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.
