開口式機架由機架底座和上橫梁組成。

開口式機架是型鋼車間常見的一種機架形式。這種機架的優(yōu)點是制造簡單，裝卸、換輥方便。其缺點是強度和剛度較低，軋輥輥跳值較大，影響產(chǎn)品精度，故只適用于大型軋機。

The open frame is of the frame base and the upper cross beam.  

The open frame is one of the most common forms in the steel workshop. The advantages of this frame are simple manufacturing, loading and unloading, and convenient for roll change. Its disadvantage is that its strength and stiffness are low, the roll roll value is larger and the precision of the product is affected, so it is only suitable for large rolling mill.

輥式軋機生產(chǎn)率可以很高，有的可達到2000-4000 件/小時甚至更高，易于實現(xiàn)自動化生產(chǎn)?？傊?，輥式軋機適用于對產(chǎn)品精度要求不高，且同時軋制一個或幾個零件的情況。輥式軋機是三種類型中運用多的一種。圓弧式軋機適用于大批量的為以后鍛造供坯的生產(chǎn)情況。In1553theFrenchlawAdlercloth(Brulier)rolledgoldandsilverplate,usedinthemanufactureofcoins。

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.

六輥軋機，軋機專業(yè)廠家介紹，這種軋機的輥系相對來說比較穩(wěn)定，而且其主要是由一對工作輥和兩對支承輥組成。不過，其在操作上有著諸多不便，因此應用并不廣泛，通常是用于軋制海底電纜的銅帶。

Six-high mill, rolling mill professional manufacturers that the roll system of this mill is relatively stable, and it mainly cists of a pair of work rolls and two pairs of backup rolls. However, it has many inconveniences in operation, so it is not widely used, usually used for rolling high-precision submarine cable copper strip.
