The invention discloses a smelting method for a steel ball for a bearing. The steel ball is formed by smelting polymerized carbon powder, silica fume powder, a ferric salt compound, titanium dioxide, aluminum powder, chromium, hydroxyethyl cellulose, resin, xanthan gum, softener, coupling agents and curing agents through the steps of heating, fusing, shoveling, pressing, mixing, grinding and palletizing. The method is adopted for manufacturing the steel ball for the bearing, the quality of the steel ball is effectively improved, the impurity content is low, the wear-resisting property is excellent, the surface smoothness is good, the defects of the traditional technology are overcome, the smelting method has high practical value and is simple and convenient to use, and the industrialized application degree is high.
