半闭口式机架是机架与机架盖之间采用斜楔连接的一种机架。这种机架兼有开口式机架和闭口式机架的优点，圣霖650轧机，装卸、换辊方便，制造容易，并有较高的刚度，故一般大中型的型钢轧机都采用这种形式的机架。

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，650轧机价格， a large and medium-sized steel mill is adopted in this form.

闭口式机架为一整体铸件制成。这种机架形式在型钢车间中小型轧机上应用较多。其优点是强度和刚度较高，辊跳值较小，产品精度较高。其主要缺点是制造比较困难，装卸、换辊不方便。轧制压力较大、对轧件尺寸要求比较严格时常采用闭口式机架。如初轧机、型钢连轧机和型钢成品轧机等。

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，650轧机哪家好， etc.

轧机专业厂家介绍，在热轧机运行的过程中，关于其的温度控制系统主要包括两个部分，650轧机，分别为可逆轧机温度控制系统以及连轧机温度控制系统。

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.
