Chrome-plating-free cold roll and producing method thereof

The invention discloses a chrome-plating-free cold roll and belongs to the field of production of metallurgical rolls. The cold roll comprises chemical components in percentage by mass as follows: 0.85%-0.95% of C, 0.50%-0.80% of Mn, 8.00%-9.00% of Cr, 2.00%-3.50% of Mo, 1.00%-2.20% of V, 1.10%-1.80% of W, less than or equal to 0.35% of Si, less than or equal to 0.20% of Ni, less than or equal to 0.015% of P, less than or equal to 0.010% of S and the balance of Fe and inevitable impurities. According to the cold roll, the alloy ratio is further optimized, the grinding performance of the roll is improved on the basis that the high abrasion resistance and roughness retention capacity is guaranteed, various roughness requirements of a cold-rolling mill can be met through adjustment of grinding parameters, the surface quality of the roll is good, and the chrome-plating-free cold roll reaches the same level of chrome-plated rolls in the aspects of rolling cycle, plate surface cleanness and rolled plate quality and
