Advantages(cast iron roll) Casting and freezing under the effect of centrifugal force, to make the roll has fine configuration, uniform white iron layer, avoid the defects of gas hole, sand explosion and residue, etc. Cast iron rolls can inlay shaft to shaft sleeve, significantly save on raw material consumption and reduce the weight of roll .
High Chromium Cast Steel Rolls . The hardness of High Chromium Cast Steel Rolls rolls is as high as 65-80 HSC.Its matrix gives itself excellent wear resistance and good fire-crack resistance. HiCrS rolls have a low carbon content range of about 10%.
Properties. Thanks to its high content of M 7 C 3 type carbide in the range of 20-30% and discontinuous network distribution of carbide, the roll offers a high wear resistance performance. The matrix consist of tempered martensitic and sorbite with finely-dispersed secondary carbides (M 7 C 3, M 23 C 6 and M 3 C types), increasing therefore the wear resistance of roll.
2.1. High-chromium white cast iron characteristics High-chromium white cast irons are ferrous alloys containing 11-30% Cr and 1.8-3.6% C along with variable amounts of molybdenum, manganese, copper and nickel . The standard procedure most commonly used for the classification of this kind of cast iron alloy is ASTM A532-10 (2014).
