Product Introduce

The main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. The roll is mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing, and the rolling force is transmitted to the stand through the bearing seat and the pressing device. The shaft head of the transmission end is connected with the gear seat through the connecting shaft, and transmits the rotating torque of the motor to the roller. The rolls can be arranged in the form of two rolls, three rolls, four rolls or multiple rolls in the rolling mill stand.

There are many ways to classify rolls, mainly:

(1) According to product types, there are strip steel rolls, section steel rolls, wire rod rolls, etc.;

(2) According to the position of the rolls in the mill series, they are divided into billet rolls, rough rolls, Finishing rolls, etc.;

(3) According to the functions of the rolls, there are scale-breaking rolls, perforated rolls, smoothing rolls, etc.;

 (4) According to the material of the rolls, there are steel rolls, cast iron rolls, cemented carbide rolls, ceramic rolls, etc.;

(5) Press The manufacturing methods are divided into casting rolls, forging rolls, surfacing rolls, sleeved rolls, etc.;

(6) According to the state of the rolled steel, there are hot rolls and cold rolls. Various classifications can be combined accordingly to make the rolls have a clearer meaning, such as centrifugal cast high chromium cast iron work rolls for hot rolled strip steel.
