1. , a kind of manufacture method of wear-resistant composite roller is characterized in that, may further comprise the steps:

  • 1) steel pipe is processed in the collars overlaps, and recessing on the outer surface that in collars, overlaps, recess width 10-15mm, depth of groove 10-12mm, flute pitch 15-25mm;

    2) cover in the collars is washed with watery hydrochloric acid and alcohol successively, dry back applies the borax of a layer thickness 0.8-1.2mm in collars lining the outer surface of and groove, dries to be placed in the casting mold;

    3) outer antifriction metal (AFM) liquation is entered metal mold cavity by cup, sprue, ingate successively, obtain the compound roller shell of castingin;

    4) the compound roller shell of castingin is heat-treated and machining after dead head cleaning and surface finish, combine by spline with cast steel or forged steel roll shaft at last and interference fit in one, the magnitude of interference is 0.10-0.15mm, obtains wear-resistant composite roller.
