What are the rollers used for?

The roller is an important part of the rubber machine in the rubber factory. It uses the pressure generated by a pair or a group of rollers to roll steel. It mainly bears the effects of dynamic and static loads, wear and temperature changes during rolling.

The main working parts and tools on the rolling mill that produce continuous plastic deformation of rubber. The roll mainly consists 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 transmits the rolling force to the frame through the bearing seat and the pressing device. The transmission end shaft head is connected to the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roller. The rolls can be arranged in the form of two-roller, three-roller, four-roller or multi-roller in the rolling mill frame.

There are many ways to classify rolls, the main ones are: (1) According to product type, they are divided into strip steel rolls, profile steel rolls, wire rod rolls, etc.; (2) According to the position of the rolls in the rolling mill series, they are divided into blank rolls, rough rolls, Finishing rolls, etc.; (3) According to the roll function, it is divided into scale breaking roller, perforated roll, smoothing roll, etc.; (4) According to the roll material, it is divided into steel roll, cast iron roll, cemented carbide roll, ceramic roll, etc.; (5) According to the roll material The manufacturing methods are divided into casting rolls, forging rolls, cladding rolls, nested rolls, etc.; (6) According to the state of the rolled steel, they are divided into hot rolls and cold rolls. Various classifications can be combined accordingly to give the rolls a clearer meaning, such as centrifugally cast high chromium cast iron work rolls for hot rolled strips.
