A manufacturing method of a marine gear box wear ring with a steel core plate mainly includes the following steps of firstly, preparing a material, wherein the surface wear-resistant layer of the wearring is prepared from 75% of Cu, 4% of Sn, 2% of Zn, 5% of Pb and 1% of Ni; secondly, mixing the material, wherein the mixture prepared in the first step is put in a mixer to be mixed; thirdly, plating a core plate with copper, wherein the core plate is plated with copper through an electroplating method to prepare the copper-plated core plate; fourthly, conducting spraying and presintering, wherein the powdery material mixed in the second step is evenly sprayed on at least one surface of the core plate through a spraying machine, and the core plate is put in a mesh belt furnace to be sintered to prepare a wear-reduction layer; fifthly, conducting groove rolling, wherein the wear ring subjected to spraying and presintering in the fourth step is put in a groove rolling die and subjected togroove rolling on a press
