The invention discloses a technology for processing a CrNiMo series steel material. The technology comprises the steps of adopting an electroslag remelting technology to obtain a steel ingot which contains 0.14-0.19% of C, 1.5-1.8% of Cr, 0.17-0.35% of Si, 0.4-0.6% of Mn, 0.25-0.36% of Mo, 1.4-1.7% of Ni, 0-0.035% of P and 0-0.030% of S according to percent by weight, forging the steel ingot, then carrying out normalizing and high temperature tempering, carburizing, high temperature tempering and oil quenching, and finally, carrying out low temperature tempering to complete the processing. According to the technology, a heat treatment processing technology which is simple and easy to operate is utilized to ensure the product quality, the problem that a loading part of a coal machine fails to work is solved, the service life of a product is prolonged, and the producing and processing costs are lowered.
