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.

五輥軋機，軋機專業(yè)廠家介紹，這種軋機也可以進行更為細致的分類，其中一種可以可以用于軋制比較難變形的金屬和合金帶材，另外一種常用于軋制厚度公差很小的不銹鋼、碳鋼和有色金屬帶材。

Five-high mill, mill professional manufacturers, this kind of mill can also be more detailed classification, one can be used for rolling more difficult to deform metal and alloy strips, another is often used for rolling thin tolerance of stainless steel, carbon steel and non-ferrous metal strips.
