Definitions

  • the present invention relates to an electrolytic dressing device and an electrolytic dressing method suitable for cylindrical grinding of steel rolls for rolling.
  • steel rolling rolls such as cast steel and tool steel (die steel, high speed steel).
  • hot rolling which involves rolling hot materials, the material is heated and is at a high temperature, making it soft.
  • the purpose of hot rolling is to reduce the thickness of the material by crushing the material as much as possible during high temperatures.
  • Large diameter cast steel rolls are used for hot rolling. After hot rolling, it is shaped into plates and coils, resulting in thick plate products.
  • Cold rolling is the process of rolling a hot-rolled plate product into a thin plate or ribbon product. The plates and coils have already been cooled and are at room temperature.
