Tungsten Carbide Standard Ring Roller

Short Description:

RenQiu HengRui Tungsten Carbide Roller  hot rolls and cold rolls are two different types of rolls used in metal rolling processing, the main difference lies in the materials and processes used. 1. Different materials: Carbide hot rolls generally choose special materials such as high strength and high temperature oxidation resistance, while cold rolls usually choose high-quality cast iron, alloy cast iron and other materials. 2. Different processes: Carbide hot rolls need to be processed at high temperatures, so they need to have high strength, high heat resistance, high wear resistance, high oxidation resistance and other properties, and require strict processing technology control. Cold rolls need to be processed at room temperature, so the requirements for hardness and strength are relatively low.
