閉口式機(jī)架為一整體鑄件制成。這種機(jī)架形式在型鋼車間中小型軋機(jī)上應(yīng)用較多。其優(yōu)點(diǎn)是強(qiáng)度和剛度較高，輥跳值較小，產(chǎn)品精度較高。比如二輥軋機(jī)，其的主要特點(diǎn)就是結(jié)構(gòu)簡單、用途廣泛，也包括可逆式和不可逆式兩種。其主要缺點(diǎn)是制造比較困難，裝卸、換輥不方便。軋制壓力較大、對軋件尺寸要求比較嚴(yán)格時(shí)常采用閉口式機(jī)架。如初軋機(jī)、型鋼連軋機(jī)和型鋼成品軋機(jī)等。

The closed frame is made of a whole castings. This type of frame is used more in the small and medium mill in the steel workshop. Its advantages are that the strength and stiffness are high, the roll jump value is small and the precision of the product is high. Its main disadvantage is that it is difficult to manufacture, and it is inconvenient to load and load and change the roll. When the rolling pressure is larger and the requirements for the size of the rolled piece are strict, the closed frame is often used. Such as the early rolling mill, the type steel continuous rolling mill and the steel finished rolling mill, etc.

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)廠家介紹，其實(shí)從實(shí)際生產(chǎn)作業(yè)來看，關(guān)于冷軋機(jī)的安全生產(chǎn)主要包括三個(gè)方面，分別為：定期檢修、日常安全操作以及日常的培訓(xùn)管理等。

In fact, from the actual production operation, the safety production of the cold rolling mill mainly includes three aspects, which are the regular maintenance, the daily safety operation and the daily training etc.
