Chilled Cast Iron Rolls for Indefinite Chilled Double Poured Cast Iron ICDP mill Rolls

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.
OEM and ODM is available

Application
bar & wire rod mill, hot strip mill, cold strip mill, PC mill, section mill, plate rolling mill and nonferrous mill etc.
