              軋制變形制度:即一定軋制條件下從坯料到成品的總變形量和軋制的總道次,各機(jī)組的總變形量各道次的變形量,軋制方式等。而一些大型高延性盤(pán)螺冷軋機(jī)生產(chǎn)線來(lái)說(shuō)的話,其電機(jī)的功率本身就很大。對(duì)于型鋼,軋件在孔型中軋制,并且在每個(gè)孔型中軋制一道,因此,型鋼的變形制度是以孔型的形式表示的,孔型的設(shè)計(jì)確定后變形制度就確定了。



              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.


              鋼錠或鋼坯在常溫下很難變形,不易加工,需要進(jìn)行加熱到1100℃到1250℃進(jìn)行軋制,這種軋制工藝叫做熱軋。在常溫下的軋制一般理解為冷軋.


              Ingot or billet are difficult to be deformed at normal temperature and are not easy to be processed. They need to be heated to 1100 and 1250 C for rolling. This rolling process is called hot rolling. Rolling at normal temperature is generally understood as cold rolling.


              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.
