The invention relates to a manufacturing method of wear-resistant transmitting roll and belongs to manufacturing methods of transmitting rolls for steel rolling equipment. The manufacturing method comprises the following steps: 1, manufacturing a transmitting roll blank; 2, forming and manufacturing a transition buffering layer, and carrying out primary plasma deposition to obtain a 1Cr18Ni9Ti buffering layer; 3, forming and manufacturing a transmitting roll working face, and carrying out plasma deposition on a buffering depositing layer to obtain a 1Cr18Ni9Ti-NiCrMoCo-WC alloy layer which is 3-4mm thick; and 4, grinding to manufacture a formed transmitting roll. According to the manufacturing method disclosed by the invention, particle sizes of 1Cr18Ni9Ti powder and NiCrMoCo-WC powder are respectively 100-200 meshes and 200-300 meshes; in percentage by mass, 35-70 percent of the1Cr18Ni9Ti powder and 65-30 percent of the NiCrMoCo-WC powder are adopted; the NiCrMoCo-WC powder is mainly prepared from 10.5-15.5 percent of Ni, 12.5-25.0 percent of Cr, 2.0-5.5 percent of Mo, 0.2-1.0 percent of Co and 45-65 percent of WC and is treated by vacuum melting and gas atomization formation to prepare spherical particles, and the 1Cr18Ni9Ti powder is mixed with the spherical particles mechanically to form a depositing powder material of the transmitting roll working face. The manufacturing method has the advantages that 1, the service life of the transmitting roll is prolonged; 2, the compatibility of alloys is improved, so that the crack sensitivity of the depositing layer of the alloys is lowered; 3, the two alloys are fully mixed to form high-performance surface quality; and 4, the manufacturing method can be applied to forming and manufacturing of the transmitting roll.
