The specific types of metal rolling mill and their simple understanding
- Jun 26, 2018 -

The metal rolling mill in the rolling mill is a specific rolling mill type obtained by dividing the rolling material by rolling material. Therefore, as the name suggests, this rolling mill is made of metal material on the rolling material, and the main function is to complete the metal rolling. This work. And from the current point of view, the application of metal rolling mills is also very extensive and can be used in many industries and fields.


Metal rolling mills are generic and collective, so they can be reclassified, such as by the number of rolls or the arrangement of racks. Moreover, under different classification criteria, there are different kinds. Therefore, in the following, it is worthwhile to classify the metal rolling mill from the angle of the number of rolls and briefly introduce some specific types.


Two-Roll Metal Rolling Mill: The main advantages of this type of rolling mill are its simple structure and wide application, and it can be divided into two kinds, reversible and irreversible. In the roll diameter of the mill, it can reach 1500mm and the length of the roll body can reach 3500mm. In the mill rolling speed, it is generally 3-7 m/s.


Three-roller metal rolling mill: The rolling process is to allow the rolling pieces to be alternately rolled from the upper and lower roll gaps to the left or right. However, due to its poor performance and use effects, there are gradually two rolls. The trend of replacing the mill.


Four-high metal rolling mill: The main features of this rolling mill are the small diameter of the work rolls and the bearing roll bearing performance. It is also very rigid, so it can be used to roll thin metal sheets and can be used as a plate mill and cold Use the mill and the complete machine.


Five-high metal rolling mill: It can also be divided into two types. One is used to roll hard-to-deform metal and alloy strips, and the other is changed in the intermediate rolls to make it adjustable. To ensure the rolling thickness, it can be used for rolling stainless steel, carbon steel and non-ferrous metal strips, but the thickness tolerance is smaller.


Six-high metal rolling mill: It has a pair of work rolls and two pairs of backup rolls on the rolls, so it has a more stable roll system. The rigidity of the equipment is similar to that of a four-high mill, and is mainly used in the rolling of copper tapes for cables.


Multi-roller metal rolling mill: A multi-roller metal rolling mill mainly includes twelve rolls, twenty rolls, and thirty-six rolls. In this type of metal rolling mill, the work roll is smaller in the roll diameter, and the roll diameter of the backup roll is larger. The advantages of the rolling mill are high rigidity, large rolling reduction and small rolling force, and can be used to roll extremely thin strips. Therefore, a multi-roll mill can be used for foil rolling. It is 200-1000mm and rolling thickness is 0.0015-0.012mm.
