Abstract

The invention belongs to the metal material field and discloses a novel improved roll material, particularly a material for forged steel rolls. The material comprises component elements by the following weight percentages: C, 0.86%-0.98%; Si, 0.60%-0.90%; Mn, 0.30%-0.45%; Cr, 3.10%-3.80%; Ni, 0.40%-0.60%; Mo, 0.30%-0.50%; V, 0.05%-0.10%; P less than or equal to 0.020%; S less than or equal to 0.015%; Fe and other unavoidable impurities, the rest. As the component elements are adopted, the roll after heat treatment is improved with quenching hardness, depth of hardening zone and wearing resistance, thereby prolonging the service life of the roll.

Description

technical field [0001] The invention belongs to the field of metal materials, and relates to the improvement of roll materials, in particular to a material of high wear-resistant rolls. Background technique [0002] Due to the sharp increase in my country's steel output, steel plates and non-ferrous metal plates continue to increase, and a large number of forged steel rolls are required for steel mills and non-ferrous processing enterprises. The research and development of new materials for forged steel rolls has always been a difficult problem and a tackling project for related enterprises at home and abroad. [0003] However, the existing roll materials 9Cr2Mo and MC3 have the disadvantages of relatively thin hardened layer, low hardenability, poor wear resistance, and short service life, which lead to low quality of rolling surface materials, increasing production costs and energy consumption of enterprises, Reduce the economic benefits of the enterprise.
