24R steel single row:

There are many types of rollers, and they all have their own unique functions. According to the technological process, they are divided into calendering rollers, smoothing rollers, casting rollers, etc., and according to their functions, they are divided into heating rollers, cooling rollers, take-off rollers, and supporting rollers. The structure is divided into seamless steel tube roller, forging and centrifugal casting roller, etc. In short, different processes of plastic products require different rollers. Therefore, as a roller manufacturer, in the process of undertaking roller production, it should design and manufacture corresponding rollers for different products and different processes to ensure that the rollers are in good condition. Play its normal role in the production process.

Regardless of the process method used, the structure, design, material selection and manufacturing of the roller should meet the following basic requirements:

1. The roller should have sufficient rigidity to ensure that the bending deformation does not exceed the allowable value under heavy load.

2. The surface of the roller should have sufficient hardness, generally required to reach HRC50 degrees or more, with strong corrosion resistance. The coating has anti-stripping ability to ensure that the working surface of the roller has good wear resistance and corrosion resistance.

3. The working surface of the roller should be finely processed to ensure dimensional accuracy and surface roughness. The roughness should be above Ra0.16, without pores or grooves. The wall thickness of the working surface of the roller must be uniform, otherwise the temperature of the roller surface will be uneven and the product quality will be affected. ? 4. The material of the roller should have good thermal conductivity, usually chilled cast iron, cast steel or molybdenum-chromium alloy steel in special circumstances, whether it is heating or cooling, can achieve rapid and uniform.
