We adopt the hard alloy particle welding technology, which forms a high-temperature metal melt pool on the surface of the workpiece, and uniformly sends the hard alloy particles into the melt pool. After cooling, the hard alloy particles form a hard alloy layer. Due to the melting and solidification of the metal body, a wear-resistant layer is formed, and there are no issues such as dissimilar welding cracks or peeling. The product has extremely high wear resistance and is highly favored by European and American customers.
High hardness: The hardness of tungsten carbide materials is very high, with tungsten carbide particles having a hardness of HRC70-75, which is only surpassed by a very small number of materials such as diamond. This high hardness enables tungsten carbide rollers to resist strong wear and friction.
Excellent wear resistance: The wear resistance of tungsten carbide coating far exceeds that of ordinary steel, which can significantly extend the service life of the pressure roller and reduce maintenance frequency. In industries such as papermaking, tungsten carbide coating can effectively resist the wear of fibers and minerals in pulp, maintaining the durability of the pressure roller.
Good corrosion resistance: Tungsten carbide coating has good resistance to various chemical media and can maintain stable performance in harsh working environments. This is particularly important for applications in industries such as chemical engineering, as it can reduce the impact of corrosion on the pressure roller and maintain its stable performance.
Wide application areas: Tungsten carbide pressure rollers are widely used in the processing and manufacturing of metal materials such as steel, aluminum, copper, stainless steel, etc., which can improve production efficiency and product quality.
The roller shell, commonly known as the Roller Shell or roller shelskin, is an indispensable working component and vulnerable part of the pellet machine. It mainly works in conjunction with pellet machine molds, responsible for processing and shaping various biofuel pellets, animal feed, and other particulate matter. The functions of the roller shell include cutting, kneading, inlaying, and squeezing.
HMT company is committed to research, development, and experimentation in this area, and has achieved significant results. Customized professional pressure rollers for customers based on material characteristics, highly praised by domestic and foreign customers.
