600rolling mill-圣霖国际【客户至上】

轧制H型钢时，轧机作为机架使用，带有两个水平辊和两个立辊，对轧件的腹板和翼缘四面碾压。轧制普通型钢时，420rolling mill，轧机转换成两辊机架，盘锦rolling mill，即不带立辊，只带有两个水平辊，对轧件进行轧制.

When rolling H steel， the universal mill is used as a universal frame， with two horizontal rolls and two vertical rolls，350rolling mill， which are rolled over the web and flange of the rolled piece. When rolling ordinary steel， the universal rolling mill is converted into a two roll frame， that is， without a vertical roll， with only two horizontal rolls， rolling the rolled piece.

开坯机为两辊水平轧机，坯料送至轧机前后，根据轧制程序表进入相应的轧槽可逆轧制，600rolling mill，并通过翻钢装置将轧件夹紧进行翻转。一般轧制5-7道次(多9道次)。

The blooming machine is a two roll horizontal mill， and the billet is sent to the front and rear mills. According to the rolling schedule， the roll is rolled into the corresponding rolling groove， and the workpiece is clamped and turned through the turning device. The general rolling is 5-7 times (up to 9 times).

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 ***all and medium mill in the steel workshop. Its advantages are that the strength and stiffness are high， the roll jump value is ***all 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.
