Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.

Due to the rapid development of the foundry industry in China in recent years, this has driven the development of the foundry machine tool industry to some extent, and has achieved remarkable results, and continues to develop steadily. According to relevant data, the Shenyang Machine Tool Group's casting machine tool production has achieved the world's top ranking.
Although the development of China's foundry machine tool industry has achieved certain results, its development is still facing a number of constraining issues, especially compared with the foreign foundry machine tool industry, China's foundry machine tool industry is significantly behind the level of manufacturing process, This makes it have obvious deficiencies in the technical level and running speed of the core running parts, the product precision retention and the reliability of the machine tool.
At present, China's foundry machine tool companies lack the awareness and ability of independent innovation and basic theoretical research, which restricts the development of our country's foundry machine tool technology. To change this situation, it is necessary to thoroughly study the user industry product process characteristics and requirements, combined with technology Features Develop high-level processing equipment. At the same time, we must also pay attention to the research of basic theoretical work, so that our country's foundry machine tool industry will have better development in the near future.
However, experts pointed out that China's foundry machine tool industry still faces some restrictive factors. Among them, the backwardness of the technological level of the casting machine is a major bottleneck. Only by breaking this bottleneck, China's foundry machine tool industry may achieve substantial breakthroughs and achieve rapid development in the steady development.
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
