Chilled Cast Iron Rolls alloy infinite chilled cast iron roll ICDP

  • The alloy infinite chilled cast iron roll(ICDP) is centrifugal casting, it has double chemical, the outside has a high tensile strength and the inside is a lower one, the drop of the hardness is lower.It is usually used for the finishing mill to roll the final material, to roll the angles, bars, flats and so on.
  • Standard includes ISO, GB, ASTM, DIN, JIS.
  • Application
bar & wire rod mill, hot strip mill, cold strip mill, PC mill, section mill, plate rolling mill and nonferrous mill etc.
