Metal guide guiding wheel based on carbide composite material

The invention discloses a metal guide guiding wheel based on a carbide composite material. The metal guide guiding wheel comprises a guide guiding wheel body. The outer end of the guide guiding wheelbody is clad with a protective alloy layer, and the guide guiding wheel body is in clearance fit with the protective alloy layer. The protective alloy layer comprises, by mass percentage, 22.4-33.5% of tungsten, 0.75-1.45% of carbon, 15.6-16.7% of copper, 5.6-6.7% of cobalt and the balance iron, wherein the conditions that S is smaller than 0.032, and P is smaller than 0.045 are met. According tothe metal guide guiding wheel, the metal guide guiding wheel with good wear resistance and high temperature resistance can be obtained by selecting the components of the guide guiding wheel body and treating the guide guiding wheel body through various steps; by selecting the carbide composite material, on the one hand, the comprehensive performance of the metal guide guiding wheel is good, and onthe other hand, the cost i
