Abstract

The invention discloses a wear-resistant rare earth alloy material for a rolling mill guide and guard device and a heat treatment method for a rolling mill guide and guard device. The wear-resistant rare earth alloy material comprises, by mass, 1.4-1.6% of C, 1.1-1.3% of Si, 1.1-1.3% of Mn, 1.7-2.0% of Cr, 0.1-0.2% of Mo, 0.1-0.4% of Ni, 0.03-0.04% of V, 0.02-0.04% of Nb, less than or equal to 0.02% of P, less than or equal to 0.03% of S, 0.1-0.3% of rare earth element and the balance of Fe. The heat treatment method comprises: putting a rolling mill guide and guard device prepared from the wear-resistant rare earth alloy material into a furnace, carrying out annealing treatment, pretreating the rolling mill guide and guard device, carrying out intermediate frequency quenching treatment onthe rolling mill guide and guard device through a batch-type furnace and a well-type electric furnace and carrying out tempering treatment. The wear-resistant rare earth alloy material has the advantages of long service life and excellent wear resistance.

Description

technical field [0001] The invention relates to the field of wear-resistant rare-earth alloy materials, in particular to a wear-resistant rare-earth alloy material for rolling mill guides and a heat treatment method for rolling mill guides. Background technique [0002] A rolling mill is the equipment that realizes the metal rolling process. Generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment, etc., but generally speaking, the rolling mill often only refers to the main equipment, and the rolling mill is mainly composed of rolls, rolling mill archways, bearing packages , bearings, worktables, rolling guides, rail seats, roll adjustment devices, upper roll balance devices, and roll change devices. [0003] The guide refers to the device installed before and after the roll pass to help the rolled piece enter and exit the rol...
