High hardness Tungsten Carbide Roller Ring for High Speed Rolling of Alloy Steel Bars

Carbide roller rings were born with the development of the metal processing industry after the advent of powder metallurgy technology in 1909. Since the introduction of cemented carbide wire drawing dies in Germany in 1918, it has stimulated research on cemented carbide in various countries, and rolls for various purposes have also appeared one after another. However, the large-scale application of cemented carbide rollers came after 1960. In 1964, the birth of the first high-speed twist-free wire rod rolling mill of Morgen Company increased the finishing speed of wire rod by 4 times. Since the finishing rolling mill unit works at high speed and high stress, the cast iron rollers and tool steel rollers have poor wear resistance, the rolling groove life is short, and the repair and loading and unloading of the rolls are very frequent, which affects the efficiency of the rolling mill and is no longer suitable for finishing rolling production. requirements, so it was replaced by combined carbide rollers. There are more than 200 root mills in the world, which consume hundreds of tons of cemented carbide rolling every year.
