High chromium cast steel roll is manufactured by centrifugal casting process with high-Cr steel as the work later and nodular cast iron as the core, the material of work layer container 8-15% chromium, 1.0-1.8% carbon, as well as some alloyed elements such as molybdenum, nickel, vanadium etc. Through rational chemical composition allocations, normalized and tempered heat treatment, the final matrix can be controlled as tempered troostite, tempered sorbite, needle-liked bainite and some discontinuousM7C3 carbides.

Because of the existence of chromium matrix and fine carbides, the high or-steel possesses excellent thermal cracking and wearing resistance. This kind of rolls could be used widely, especially in the roughing stands of hot strip continuous rolling mills.
