Composite metal guide and guard guide wheel

The invention discloses a composite metal guide and guard guide wheel. The composite metal guide and guard guide wheel comprises a guide and guard guide wheel body. The guide and guard guide wheel body comprises a first metal layer 1. Chemical components of the first metal layer I comprise, by mass, 1.65-1.83% of C, 13.5-16.3% of Cr, 6.5-7.5% of B, 1.33-1.57% of Mo, 3.65-3.77% of Mn, 0.43-0.68% ofAl, 0.135-0.146% of RE, 0.078-0.092% of Mg, 0.223-0.310% of V and 0.045-0.053% of N. The components of the guide and guard guide wheel are selected and used and are subjected to treatment of all steps, and the metal guide and guard guide wheel with high wear resistance and high temperature resistance can be obtained. Through selection and use of a carbide composite, the manufacturing cost of thecomposite metal guide and guard guide wheel cannot be too high because of the pursuit of the properties. 本发明公开了种复合金属导卫导轮,包括导卫导轮，所述导卫导轮包括第金属层1，所述第金属层1的化学成分及其质量百分含量(％)为：C：1.65-1.83％，Cr：13.5-16.3％，B：6.5-7.5％，Mo：1.33-1.57％，Mn：3.65
