The invention relates to the technical field of shot blasting treatment, in particular to a 18CrNiMo7-6 steel carburization element shot blasting process. A 18CrNiMo7-6 steel carburization element isa wind power gear element with the diameter being greater than 1000mm. The process parameters are as followings: the shot conveying quantity is 10kg/min; the shot blasting pressure is 0.42Mpa; the rotating speed is 2.4 to 10rpm; the upward and downward walking speed is 38mm/min; the reciprocating times is 1 to 2; the shot blasting time is 11 to 34.4min. The shot blasting uses steel wires with thehardness being 58 to 63HRC for shot cutting; the diameter is 0.7mm, G2. When the process is used, the surface residual pressure of the steel carburization element reaches the requirement of 500MPa orhigher; the subsurface and the stress depth meet the requirements.
