機(jī)架是軋鋼機(jī)的主要部件，它在軋鋼過(guò)程中承擔(dān)金屬變形給予的負(fù)荷。因此要求機(jī)架有足夠的強(qiáng)度和剛度，以保證設(shè)備安全和產(chǎn)品質(zhì)量。型鋼軋機(jī)的機(jī)架形式較多，常見(jiàn)的機(jī)架形式有開(kāi)口式機(jī)架、閉口式機(jī)架和半閉口式機(jī)架3種。

The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to have sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.

半閉口式機(jī)架是機(jī)架與機(jī)架蓋之間采用斜楔連接的一種機(jī)架。這種機(jī)架兼有開(kāi)口式機(jī)架和閉口式機(jī)架的優(yōu)點(diǎn)，裝卸、換輥方便，制造容易，并有較高的剛度，故一般大中型的型鋼軋機(jī)都采用這種形式的機(jī)架。

A semi closed frame is a frame with a wedge between the frame and the frame cover. The rack has the advantages of open frame and closed frame. It has the advantages of loading and unloading, easy roll changing, easy manufacture and high rigidity. Therefore, a large and medium-sized steel mill is adopted in this form.

楔橫軋機(jī)類(lèi)型有輥式、板式和單輥弧式楔橫軋機(jī)。三種類(lèi)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.
