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。其主要缺點(diǎn)是制造比較困難，裝卸、換輥不方便。關(guān)于機(jī)械產(chǎn)量，二十世紀(jì)七十年代后期，控制冷卻技術(shù)的發(fā)展使得鋼板軋制中的TMCP技術(shù)得到廣泛發(fā)展。軋制壓力較大、對軋件尺寸要求比較嚴(yán)格時常采用閉口式機(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.

軋機(jī)專業(yè)廠家介紹，在熱軋機(jī)運(yùn)行的過程中，關(guān)于其的溫度控制系統(tǒng)主要包括兩個部分，分別為可逆軋機(jī)溫度控制系統(tǒng)以及連軋機(jī)溫度控制系統(tǒng)。

In the process of rolling mill, the temperature system of the hot rolling mill mainly includes two parts, which are the temperature system of the reversible rolling mill and the temperature system of the continuous rolling mill.
