Novel multi-element alloy grinding forging and preparation method and heat treatment process thereof

Abstract

The invention discloses a novel multi-element alloy grinding forging and a preparation method and a heat treatment process thereof. The novel multi-element alloy grinding forging comprises the following components in percentage by weight: 2.2 to 2.8 percent of C, less than or equal to 1.0 percent of Si, less than or equal to 0.8 percent of Mn, more than or equal to 10 percent of Cr, 0.05 to 0.15 percent of Re, less than or equal to 0.05 percent of P, less than or equal to 0.05 percent of S, 0.1 to 0.3 percent of V, 0.05 to 0.2 percent of Ti, 0.05 to 0.08 percent of Al, and the balance of Fe. The novel multi-element alloy grinding forging is formed by adopting a metal mold sand coverage process, the thickness of a sand coverage layer of the forging is between 3mm and 4mm, and the size of the novel multi-element alloy grinding forging is phi (40-60)mm*(50-70)mm. By adjusting the content of the C, Si, Mn, Cr, Re, P, S, V, Ni and Al elements, controlling the thickness of the sand coverage layer in the preparation process and adjusting the heat treatment process, the obtained novel multi-element alloy grinding forging has the advantages of good mechanical property, strong impact toughness and low unit abrasion.

Description

technical field [0001] The invention relates to the technical field of abrasive materials, in particular to a novel multi-element alloy grinding forging, a preparation method and a heat treatment process thereof. Background technique [0002] Grinding and forging is the key equipment for crushing materials after they are crushed. It is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industries. Grinding and forging is composed of a horizontal cylinder and a hollow shaft for feeding and discharging And the grinding head and other parts, the cylinder is a long cylinder, the cylinder is equipped with a grinding body, the grinding body can be divided into grinding balls or grinding forgings, the material is loaded into the cylinder from the hollow shaft at the feeding end of the grinding forging, when grinding the forging cylinder When rotating, the grinding body adheres to the liner of the cylinder...

AI Technical Summary

Problems solved by technology

[0003] During the falling and throwing process of traditional grinding forging, the impact resistance of the product is poor, and the throwing wear is relatively large. How to prepare a grinding forging that is not easy to wear, has good mechanical properties, and strong impact resistance and toughness has become a technical problem that needs to be solved urgently.
