開口式機(jī)架由機(jī)架底座和上橫梁組成。

開口式機(jī)架是型鋼車間常見的一種機(jī)架形式。這種機(jī)架的優(yōu)點(diǎn)是制造簡(jiǎn)單，裝卸、換輥方便。其缺點(diǎn)是強(qiáng)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(jī)。

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.

楔橫軋機(jī)類型有輥式、板式和單輥弧式楔橫軋機(jī)。三種類型的楔橫軋機(jī)相比，板式楔橫軋機(jī)模具制造較為簡(jiǎn)單，模具的調(diào)整比較容易，因而軋件的精度較高，并且工藝可靠.

The cross wedge rolling mill has roller type, plate type and single roll arc cross wedge rolling mill. Compared with the three types of cross wedge rolling mill, the mould manufacturing of the plate type cross wedge rolling mill is simpler and the adjustment of the die is easy, so the precision of the workpiece is high and the process is reliable.

軋機(jī)專業(yè)廠家說，熱軋機(jī)的優(yōu)點(diǎn)主要可以歸納為三個(gè)方面。一點(diǎn)，采用熱軋可以明顯的減少能耗，降低成本。此外，熱軋時(shí)可以發(fā)揮出較高的金屬塑性，而且所產(chǎn)生的變形抗力較小，能夠有效的防止金屬出現(xiàn)嚴(yán)重的變形問題。

The mill manufacturer explains that the advantages of the hot rolling mill can be summed up in three aspects. First, the use of hot rolling can significantly reduce energy cumption and reduce costs. In addition, hot rolling can give full play to the high metal plasticity, and the deformation resistance is small, which can effectively prevent the serious deformation of the metal.
