The cooling efficiency of water-quenching rollers is very high. Through high-speed spraying water, the temperature of the steel surface can be quickly reduced, while the temperature inside the steel is relatively slow. In this way, the temperature difference between the inside and outside of the steel is effectively controlled, thereby avoiding drastic thermal stress changes and reducing the occurrence of deformation.

7 types of rollers needed in the automobile manufacturing industry: 1. Coating Roller, 2. Embossing Roller, 3. Chrome Plated Roller, 4. Tungsten Carbide Roller, 5. Guide Roller, 6. Heating Roller, 7. Cooling Roller.

Steps to repair the chrome-plated surface of industrial rollers: 1. Surface inspection and evaluation 2. Surface cleaning and removal of damaged layer 3. Surface repair and re-chrome plating 4. Surface polishing and passivation 5. Final inspection and quality control
