Problems solved by technology

[0004] It can be seen that the current patents on high manganese steel mainly focus on the alloying and rare earth modification of high manganese steel using traditional processes. The performance improvement of high manganese steel is very limited, and it cannot fully adapt to medium and low impact stress conditions.

Abstract

The invention discloses a preparation technology of vanadium carbide reinforced high manganese steel base composite material, mainly comprising the following steps: weaving a vanadium wire mesh with vanadium wires; preparing mesh-type three-dimensional skeleton structure by tailoring, rolling by layers or overlying; manufacturing a casting mold according to casting technique; putting the vanadium wire mesh-type three-dimensional skeleton into a casting mold cavity in advance; smelting high manganese steel to be poured into the casting mold cavity to obtain a vanadium wire-high manganese steel binary material prefabricated body; putting the vanadium wire-high manganese steel binary material prefabricated body into a thermal treatment furnace; heating to the carbide forming temperature for preserving heat to obtain vanadium carbide reinforced high manganese steel base composite material. The composite material prepared with the method fully performs high wear-resisting property of vanadium carbide hard phase as well as favourable ductility, convenient regulation and control and reliable technology of high manganese steel, solves the problems of incomplete reaction of composite material, uneven wild phase particle distribution, weakened wild phase interface pollution and the like, and can be widely applied to the wear-resisting fields of mines, electric power, metallurgy, coal, building materials and the like.

Description

technical field [0001] The invention belongs to the technical field of metal-based composite materials, and in particular relates to a preparation process of vanadium carbide-reinforced high-manganese steel-based composite materials. Background technique [0002] High manganese steel has high strength, plasticity, low temperature toughness, work hardening, and impact resistance safety. As a wear-resistant material, in terms of resistance to abrasive wear or chisel wear under strong impact and high pressure, its wear resistance under high impact stress conditions is unmatched by other materials. Wear-resistant products such as liners, hammer heads, screen bars, and jaw plates made of high manganese steel have been widely used in metallurgy, mining, building materials, railways, electric power, coal and other mechanical equipment for a long time. However, it has been found in practice that the wear resistance of high manganese steel is conditional, and the high wear resistanc...
