軋鋼,就是在旋轉(zhuǎn)的的軋輥間改變鋼錠,鋼坯的形狀的壓力加工過(guò)程。所謂軋鋼工藝過(guò)程就是一系列軋鋼工藝過(guò)程組合而成的加工流程。


Rolling is the process of changing the pressure of the ingot and the shape of the billet between the rotating rolls. The so-called steel rolling process is a process of combination of a series of steel rolling process.


精整,是軋鋼生產(chǎn)過(guò)程中后一個(gè)工序,也是較為復(fù)雜的一個(gè)工序。他對(duì)產(chǎn)品的質(zhì)量起著終的保證作用。產(chǎn)品的技術(shù)要求不同,精整工序的內(nèi)容也不大相同。精整的工序通常又包括鋼材的卷取,軋后冷卻,矯直,成品熱處理,成品表面清理以及各種涂色等許多具體工序。


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.


棒材精軋件后為什么要采用穿水冷卻工藝?(1)提高了產(chǎn)品的力學(xué)性能;(2)減少了產(chǎn)品表面二次氧化損失;(1)切分孔型老化,切分孔出來(lái)的料在切分契尖處較厚,增加了切分刀的切分負(fù)荷。(3)穿水后,由于軋件溫度低,剛度大,在冷床輸入輥道上事故減少,軋件在冷床上冷卻時(shí)塌腰彎曲減少,可以提高成材率和產(chǎn)品質(zhì)量;(4)冷床長(zhǎng)度可相應(yīng)減少。

Why do we need to wear water cooling technology after finishing bar?

(1) improve the mechanical properties of the product; (2) reduce the two oxidation loss on the surface of the product; (3) after water, because the rolling temperature is low, the stiffness is large, the accident on the roller table of the cold bed is reduced, the bending of the rolled piece in the cold bed is reduced, the yield and quality of the product can be improved; (4) the length of the cold bed can be reduced correspondingly.




單就冷軋機(jī)的軋制速度而言,其型號(hào)就可分為兩種,一種是每秒線速度在3米的冷軋機(jī),還有一種則是線速度在20米冷軋機(jī),后面這一種設(shè)備已經(jīng)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.
