Abstract

The invention discloses an alloy roller with high abrasion resistance and high heat resistance. The alloy roller comprises the following components in percentage by weight: 2.5-3.5% of C, less than 2.0% of Si, 1.6-2.0% of Mn, less than or equal to 0.06% of P, less than or equal to 0.05% of S, less than or equal to 0.2% of Cu, less than or equal to 0.10% of As, 1.5-2.0% of Cr, 10.0-20.0% of Ni, 10.5-15.0% of Mo and the balance of Fe. Through greatly increasing the contents of Ni and Mo elements in the alloy roller with high abrasion resistance and high heat resistance, the heat-resisting property and abrasion-resisting property of the alloy roller are improved, and the service life of the alloy roller with high abrasion resistance and high heat resistance is prolonged.

Description

technical field [0001] The invention belongs to the technical field of roll manufacturing, and in particular relates to an alloy roll with wear resistance and high heat resistance. Background technique [0002] Cast steel rolls have high tensile strength and toughness, and are widely used in blanking mills or blooming mills with high rolling temperature and heavy rolling load, and can also be used as backup rolls. According to its chemical composition and heat treatment process, the alloy cast steel roll can make the matrix structure of the outer layer of the roll body be pearlite and bainite. Pearlite can be flaky or spherical, or sorbite type. Tempered sorbite not only has high strength and toughness, but also has good thermal cracking resistance, especially tempered sorbite with phase phase. It has excellent wear resistance, so when it is used in the roughing mill, the rolling effect is good. [0003] Generally, the increase of Ni content will lead to the increase of re...
