Abstract
The invention provides a rotor guide bar and a preparation method thereof. The rotor guide bar includes Zr, Ni, Co, Mg, Si, Al, Ag, Cu and unavoidable impurities. The preparation method comprises the following steps: The formula amount is ball milled and mixed with zirconium powder, magnesium powder, silicon powder, aluminum powder, silver powder, copper plate and binder. During ball milling, absolute ethanol is used to immerse the grinding material to obtain the first grinding material; the first grinding material is heat treated, and the second grinding material is obtained after cooling. Second grinding material: mix nickel powder, cobalt powder and the second grinding material according to the formula amount, use absolute ethanol to immerse the grinding material during ball milling, and obtain the third grinding material; carry out hot isostatic pressing sintering after cold isostatic pressing, heat preservation treatment After natural cooling, the rotor conductor is obtained. The preparation method is simple and practicable, and the prepared rotor bar still has excellent tensile strength, elongation and electrical conductivity at 400° C., which meets the use requirements of the asynchronous motor.
