Abstract

The invention discloses a high-wear-resistance cold roll. The high-wear-resistance cold roll comprises the following components of, in percentage by mass, 1.00%-2.00% of C, 0.01%-0.20% of N, 3.00%-6.00% of Cr, 2.00%-4.00% of Mo, 1.00%-3.00% of V, 0.10%-1.00% of Ti, 0.50%-2.00% of Si, 0.50%-1.50% of Mn and the balance of Fe and inevitable impurities. Meanwhile, the invention further discloses a preparation method of the high-wear-resistance cold roll. Compared with the prior art, the formula is more scientific and rigorous, and the impurity content is low; the preparation method is scientific,simple, low in energy consumption and less in pollution; and the high-wear-resistance cold roll prepared by the preparation method forms a large amount of uniformly distributed nitrides and carbides of Ti, V and Mo, and the nitrides and carbides are used as wear-resistant particles to increase the wear resistance of the material.

Description

technical field [0001] The invention belongs to the field of roll cold treatment, and in particular relates to a high wear-resistant cold roll and a preparation method thereof. Background technique [0002] The roll is an important part in metal rolling, how to improve the service life of the roll and the surface quality of the rolled product is an important subject in the field of metal rolling. During the rolling process of metal, rolling deformation heat, friction heat, heat of the rolled piece itself will cause the surface temperature of the roll to rise, which will cause surface thermal cracks, oxidation, and roll breakage of the roll. Therefore, in order to improve the service life of the roll and the roll is properly cooled, it is one of the important measures in the field of metal rolling. [0003] The cooling technology of the roll surface can usually be divided into two types: internal cooling technology and external cooling technology. Both of these cooling metho...
