Abstract

The invention relates to an iron-based metal and ceramic composite guide roller which comprises a high ceramic layer and an annular steel block in sequence from outside to inside. The high ceramic layer is made of, by weight, 30%-70% of 400-meshed TiC powder, 35%-60% of Fe powder, 1%-3% of Mo powder, 2%-5% of Ni powder and 6%-8% of Cr powder.

Description

technical field [0001] The invention relates to a metal-ceramic composite guide roller, in particular to an iron-based metal-ceramic composite guide roller and its sintering and welding integration process. Background technique [0002] Tungsten is a rare metal widely used in gun manufacturing, metal cutting blades, drill bits, superhard dies, wire drawing dies, etc. Tungsten has a wide range of uses, involving mining, metallurgy, machinery, construction, transportation, electronics, chemical industry, Light industry, textile, military industry, aerospace, science and technology, various industrial fields. Cobalt is not only an important metal for making alloy steel, but also an important raw material for various advanced pigments. Due to the limitation of tungsten and cobalt resources, many western countries focus on the development of tungsten-free cobalt cemented carbide with TiC ceramics as the reinforcement phase and nickel and nickel alloy as the binder phase, and hav...
