Abstract

PURPOSE:To improve required characteristics of a roll by forming the roll shape by rolling or forging the steel containing specified wt.% C, Cr, Mo, W, V and Co, further, by performing the heat treatment to keep the hardness adjacent to the surface to a specified one. CONSTITUTION:The steel having by weight, 0.8-1.4% C, 3-5% Cr, 4-7% Mo, 4-11% Co at need is rolled or forged to form into the roll shape. Then, the heat treatment is performed to keep its surface hardness being 85-90 HS and to keep the range of 5-10mm depth from the surface being >=85 HS. Carbides are formed by Cr, W, Mo, C, V and to improve an wear resistance, corrosion resistance, toughness, spolling resistance of the roll and the containing of Co promotes these properties much more. Because the hardness adjacent to the surface is maintained, each required property of the roll is improved.
