在提高质量和产量的同时，还应该力求降低成本。因此如何能够高产，低成本的生产出合乎技术要求的钢材，是制定轧钢工艺生产工艺过程的总任务和总的要求。

At the same time, we should try to reduce the cost while improving the quality and production. Therefore, how to produce high quality and low cost steel that meets the technical requirements is the general task and the general requirement for making the rolling process production process.

轧制变形制度：即一定轧制条件下从坯料到成品的总变形量和轧制的总道次，各机组的总变形量各道次的变形量，轧制方式等。轧钢机的成长都是在品质有所保证的前提下所进行的，因为品质是轧钢机生存在市场中的旗帜，只有拥有良好的品质才能让自身的旗帜在市场中高高的飘荡。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。

Rolling system: that under certain rolling condition the total deformation from the blank to the finished product and the total rolling pass, deformation of the total deformation of each unit of each pass, rolling etc.. For the section steel, the rolled piece is rolled in the pass and rolled in one pass. Therefore, the deformation system of the section steel is expressed in the form of pass, and the deformation system is determined after the pass design is determined.

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***。Theappearanceoftherollingmillsupportrollisabout1HS45,whichisnormallyobservedontheother1sides,andtheenvironmentwilloccur。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.
