5H12 roll steel processing industry with the development of materials, the development of a large number of industrial restructuring, the corresponding high-speed multi-roll rolling steel 9Cr2Mo He Deguo roll steel 86CrMoV7 it is necessary to have a new industrial method breakthroughs, to deal with strengthening and toughening of making a fuss about, in the introduction of a new roll of steel as well as new breakthroughs. Currently in high-speed rolling mill work roll drive roller has adopted what D2 (Cr12MOv; Cr12Movco) and 5H12 (5Cr5MovSi) and so on. Authors believe to have made contact with friction and wear compression fatigue, stress and point of view to selection of work roll material, to bring the incident with the anti-breaking ability to use transmission roller material.
