High-Speed Wire Rod Rolling Tungsten Carbide Rollers

High-speed wire rod rolling tungsten carbide rollers of wire production is an important tool, high-speed wire rod rolling tungsten carbide rollers at work, endure harsh working conditions, working in hot rolling mill rollers open rolling temperature is generally 1000℃ to 1180℃ finishing temperature in 800℃ above neutral or rolling weak base water cooling at room temperature, high-speed wire rod rolling tungsten carbide rollers rolling speed up the rolling speed meters per second. Working conditions require rollers rollers not only have high strength and wear resistance, must also have a high resistance to thermal fatigue and corrosion resistance, oxidation resistance.

When the high-speed wire rod rolling, rolling groove wear mechanism and tungsten carbide cutting tool wear mechanism in the process are similar, but the wear groove is more complex, more comprehensive analysis to respond to a variety of factors. Materials groove for WC-Co / WC-Co-Ni-Cr-based alloy, wherein, excellent abrasion resistance and WC substrate bonding phase Co / Co-Ni-Cr wear resistance is poor; hard interstitial alloy, WC particles are bonded by a Co / Co-Ni-Cr formed, and there is also a very complex physical and chemical reaction between WC and Co / Co-Ni-Cr. With tungsten carbide rollers as the base material, a metal cobalt or cobalt and nickel for bonding materials with high hardness, wear-resistant properties, is widely used in high-speed wire rod finishing mill.

Due to the high rollers speed, centrifugal force will change the amount of deformation in the quiet with the resulting pieces, which affects the size of the mating surface compressive stress, when the elastic modulus is accommodating member accommodating member lower than the high-speed rotation of the surface compressive stress values increase. High-speed wire rod rolling tungsten carbide rollers internal quality control is strict control of the rollers material design and production process of.
