High Chrome Cast Iron Roll for Rolling Mill

 

Properties

Thanks to its high content of M7C3 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 (M7C3, M23C6 and M3C types), increasing therefore the wear resistance of roll, The Cr2O3 enriched oxide

film on the roll surface is highly resistant to oxidization and plastic strain, making the roll extremely suitable for steel hot rolling process.

Mechanical Properties
Hardness of shell HSD65-85
Hardness of neck HSD35-48
Tensile Strength of core ≥450Mpa
