Chrome-plated rolls and textured chrome-plated rolls are widely used in galvanized lines and continuous withdrawal lines in the metallurgical industry. The roll body adopts coil or forging quenching process, especially for tension rolls. Most of the surface of the roll body is quenched. After the roll body is ground, hard chrome plating , thickness: 0.05-0.12mm, hardness: HV800-900, roughness is made according to customer needs.
Chrome plating: Our company adopts the advanced hanging immersion 360º rotation method for chrome plating, and the coating performance is not lower than the drawing requirements.
After chrome plating: the roller surface is not allowed to have defects such as chrome plating burrs, looseness, peeling, cracks, and vibration lines; the appearance of the coating is smooth and smooth, and the textured roughness is uniform.
After the coating is processed, the roller must ensure that the thickness, hardness and surface roughness of the coating meet the requirements of the drawing.
The roughness of the coating is measured by a needle-tip contact roughness meter, and the thickness of the coating is measured by an ultrasonic coating thickness gauge. The unit of measurement accuracy is microns. The hardness cannot be measured on the roll surface, if necessary, provide the metallographic test report of the test piece.
