The invention discloses a
grinding roller manufacturing /
remanufacturing abrasion-resistant material and a preparation method thereof. A
grinding roller is formed by a core roller body, a substrate abrasion-resistant layer, a
transition layer and a roller face abrasion-resistant shape layer in a
coupling mode. A core material is provided with the highly-abrasion-resistant modified
boron-containing high-
chromium cast iron substrate abrasion-resistant layer through
casting and compounding. The substrate abrasion-resistant layer comprises, by
mass, 1.75%-3.0% of C, 12.0%-18.0% of Cr, 0.2%-2.0% of B, 0.4%-0.8% of Mn, 0.4%-1.2% of Si, 0.30%-0.80% of Ni, 0.02%-0.04% of Mg, 0.03%-0.05% of Ce, 0.05%-0.10% of Ti, 0.006%-0.015% of N, 0-0.04% of S, 0-0.04% of P, and the balance Fe. Then surfacing of materials of the roller face abrasion-resistant shape layer is conducted on the surface of the
transition layer. The roller face abrasion-resistant shape layer is formed by flux-cored wires through surfacing. The flux-cored wires comprises, by
mass, 2.3%-3.5% of C, 14.0%-26.0% of Cr, 1.5%-2.0% of Ni, 0.8%-2.0% of Nb, 1.3%-2.0% of Mo, 1.2%-2.3% of Si, 1.0%-1.7% of Ti, 0.3%-1.0% of V, 0.2%-1.5% of B, 0-<0.007% of S, 0-0. 015% of P, and the balance Fe.
