High-Cr iron roll as Work roll in the roughing and previous-finishing stands of hot strip continous rolling mill

The high-Cr cast iron rolls are made by centrifugal casting process,the work layer contains 12-22% Chromium.Through rational chemical composition allocations and different heat treatments,the matrix can be controlled as sorbite,troostite,bainite or martensite and certain kinds of carbides,such as Cr7C3 eutectic carbides,Cr23C6 second carbides,Mo2C carbides etc.According to diferent purposes of use,the material of the core could be nodular iron or grey iron.We make this type of roll by centrifugal cast double poured.In this case,we can achieve an excellent wear resistance in the shell with flake graphite,bainite & martensite and primary carbide type M7C3+ secondary carbide in the microstructure.Besides the excellent wear resistance,it is also good against fire cracking thanks to the oxide flm Cr203 formed on the body surface while roling.At the same time,the core is strong enough to assure the roll can work safely.The hi-Cr iron rolls are mainly used as work rolls in the roughing & previous -finishing stands of hot strip continuous roling mills;work rolls in the roughing & finishing stands of the plate mills;work rolls in temper mills and cold strip mills;rings in the large universal mills;work rolls in the finishing stands of small section mills and bar mils.
