High-Cr Composite Spin-Cast Iron Roll
The ductile iron is generally used as the material of roll core and the roll neck for the alloy cast Iron Roll. The high alloy composite cast iron roll produced by the centrifugal composite casting process.
Due to the presence of lath-shaped M7c3, eutectic carbide, chrysanthemum M2c eutectic carbide and granular M23C6 secondary carbide in the matrix, the high chromium composite cast iron roll has excellent wear resistance and high Resilience and impact resistance, thus it is widely used as the rough rolling and finishing rolling work rolls in the hot strip rolling mill, the wide and medium plate rolling mill. as well as the finishing rolling work rolls in the small section steel and sheet rolling mill.
