Product Description

High-speed steel rolling mill replacement roller has high wear resistance and hardenability, especially the red hardness at high temperature, which makes high-performance high-speed steel more suitable for manufacturing rolls and roll rings.

Therefore, high-speed steel replacement rolls are not only suitable for plate and strip mills, but also for wire and bar mills, and have achieved remarkable results.

Features:

  • High-speed steel replacement rolls have high carbon content and high alloying elements such as tungsten, molybdenum, vanadium, chromium, niobium, etc. Therefore, the types of carbides in the roll structure are mainly MC type and M2C type, and the carbide hardness is high and has good wear resistance.
  • The HSS replacement roller has good thermal stability and the roll surface has high hardness and good wear resistance at the rolling temperature.
  • The high-speed steel replacement rolls and rings have good hardenability, and the hardness from the surface of the roll body to the inside of the working layer is almost not reduced, so as to ensure that the roll has the same good wear resistance from the inside to the outside.
  • During the use of the roll, under good cooling conditions, a thin and dense oxide film is formed on the surface of the roll body. This uniform, thin and dense oxide mold exists for a long time without falling off, making the high-speed steel roll wear-resistant Significantly increased.
  • The formation of an oxidation mold on the surface of the HSSmill rolls during rolling reduces the friction between the rolled material and the roll surface. Therefore, it is easy to cause slippage during the rolling process, which makes the adjustment of the rolling mill more difficult.
  • The high-speed steel material has a large expansion coefficient and good thermal conductivity. It is easy to cause roll shape deformation during rolling and affect the accuracy of the rolled material. Therefore, when the high-speed steel roll is used on the plate and strip rolling mill, not only the cooling system design must be changed, but also Also change the design of the roll shape.
  • Since the core of the HSSrolling rings is made of alloy ductile iron, graphite steel, or forged steel, the roll diameter is high in strength.
  • Because the high-speed steel material has good wear resistance, but the ability to resist accidents is poor, the effect of the use of high-speed steel rolls depends not only on the quality of the high-speed steel mill roll itself but also more importantly on the use conditions and maintenance of the roll.

Product Applications

Rolling mill replacement roller is used in various industries and for various applications, including:

  1. Steel production: Work rolls are used in hot rolling mills and cold rolling mills to shape and reduce the thickness of steel sheets, bars, and plates.
  2. Non-ferrous metals production: Work rolls are also used in non-ferrous metals production, such as aluminum and copper, to produce sheets, plates, and coils.
  3. Automotive industry: Work rolls are used in the production of automotive parts, such as body panels and engine components.
  4. Aerospace industry: Work rolls are used in the production of aerospace parts, such as turbine blades and engine components.
  5. Electrical and electronic industry: Work rolls are used in the production of electrical and electronic components, such as transformer cores and printed circuit boards.
  6. Jewelry industry: Work rolls are used in the production of jewelry, such as gold and silver rings, bracelets, and necklaces.
  7. Paper industry: Work rolls are used in the production of paper to smooth and flatten the surface of the paper.

In addition to rolling mills, work rolls are also used in other equipment that performs rolling operations, including roll forming machines and tube and pipe mills.
