在經(jīng)過改進(jìn)之后，320rolling mill，目前的軋機(jī)設(shè)備采用的是被動(dòng)一軋一拖式生產(chǎn)方式，可以實(shí)現(xiàn)兩道軋制成型，錦州rolling mill，不僅解決了速度配合問題，而且改變了傳統(tǒng)的四道軋制方式，生產(chǎn)效率明顯提高。

After the improvement， the current  mill equipment adopts a passive one rolling and towing mode of production， which can realize two rolling forming. It not only solves the problem of speed matching， but also changes the traditional four way rolling method， and the production efficiency is  improved.

四棍軋機(jī)的工作輥直徑較小，傳遞軋制力矩，軋延壓力由直徑較大的支承輥承受。這類設(shè)備的主要優(yōu)點(diǎn)是相對(duì)剛度較大，壓下量大、軋延力小，可軋制較薄的板材，700rolling mill，也包括有可逆和連軋兩種。

The working roll diameter of the four bar mill is **all， and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness， large reduction， low rolling force，350rolling mill， thin rolled sheets， and reversible and continuous rolling two.

輥式軋機(jī)生產(chǎn)率可以很高，有的可達(dá)到2000-4000 件/小時(shí)甚至更高，易于實(shí)現(xiàn)自動(dòng)化生產(chǎn)?？傊?，輥式軋機(jī)適用于對(duì)產(chǎn)品精度要求不高，且同時(shí)軋制一個(gè)或幾個(gè)零件的情況。輥式軋機(jī)是三種類型中運(yùn)用多的一種。圓弧式軋機(jī)適用于大批量的為以后鍛造供坯的生產(chǎn)情況。

The productivity of the roller mill can be very high， some can reach 2000-4000 pieces / hour or even higher， and it is easy to realize automatic production. In conclusion， the roll mill is suitable for the low accuracy of products and rolling one or several parts at the same time. Roll mill is the most widely used in three types. The circular arc mill is suitable for large quantities of production for forging later.
