軋鋼設(shè)備采購誠信企業(yè)推薦

軋鋼生產(chǎn)的工序十分復(fù)雜，盡管隨著軋制質(zhì)量要求的提高，品種范圍的擴(kuò)大以及新技術(shù)，新設(shè)備的應(yīng)用，組成工藝過程的各個工序都會有相應(yīng)的變化.

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.

棒材穿水冷卻裝置的基本原理是什么？

在精軋機后設(shè)有一個由數(shù)個水冷箱組成的可調(diào)水冷段，對棒材進(jìn)行急劇冷卻，使棒材表面形成馬氏體組織，在隨后的溫度恢復(fù)過程中，芯部熱量散出對表面馬氏體組織可產(chǎn)生回火作用，結(jié)果棒材表面層為回火馬氏體，芯部為細(xì)粒珠光體及索氏體組織。這種組織結(jié)構(gòu)使棒材屈服極限和韌性提高，并具有良好的可焊性。Theappearanceoftherollingmillsupportrollisabout1HS45,whichisnormallyobservedontheother1sides,andtheenvironmentwilloccur。

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.

采用控制軋制工藝時，為了防止原始奧氏體晶粒過分長大，一般采用較低的加熱溫度和開軋溫度。由于開軋溫度高，變形后的奧氏體晶粒會發(fā)生再結(jié)晶而細(xì)化，如在這個階段停止變第八節(jié)控制軋制技術(shù)形，軋件即隨溫度下降而產(chǎn)生相變。

In order to prevent the original austenite grain growing too much, the lower heating temperature and rolling temperature are generally adopted in the rolling process. Due to the high rolling temperature, the austenite grain after the deformation will be recrystallized and refined. For example, the eighth section  rolling technology is stopped at this stage, and the phase change is produced as the temperature drops.

軋鋼機的成長都是在品質(zhì)有所保證的前提下所進(jìn)行的，因為品質(zhì)是軋鋼機生存在市場中的旗幟，只有擁有良好的品質(zhì)才能讓自身的旗幟在市場中高高的飄蕩。

The growth of the rolling mill is carried out under the premise of quality assurance, because the quality is the banner of the steel rolling machine in the market. only with good quality can its flag float high in the market.
