Object of the present invention, in order to solve the problems of the technologies described above, provides a kind of Forging Technology of bearing ring, and this technique can eliminate metal latent defect, improves metal structure, and metal streamline is distributed rationally, and metal in close degree is good, extends the service life of bearing; Improve geometric accuracy and the dimensional accuracy of forging, eliminate Wall-Thickness Difference, and make forging shape to greatest extent close to the finished form of lasso, thus can reduce allowance and the tolerance of forging, improve stock utilization, reduce machining operations amount, reduce cost.Its technical scheme is as follows: a kind of Forging Technology of bearing ring, it is characterized in that, described bearing ring is made up of following component by weight percentage: C: 0.17 ~ 0.23 Ni:3.25 ~ 3.65, Cr:1.25 ~ 1.65, Mn:0.30 ~ 0.60, Si:0.17 ~ 0.37 S :≤0.035 P :≤0.035, and surplus is Fe; Described Forging Technology comprises the steps: 1), the first fire steel ingot will with above-mentioned composition adopts Medium Frequency Induction Heating Furnace heating-up temperature to 1200 DEG C, bar hold, chamfered edge, the wrong mouth of a river; 2), the second fire is to 1) the base material that obtains of step heats again, is heated to 1120 ~ 1150 DEG C, jumping-up, pulling; 3), the 3rd fire is to 2) the base material that obtains of step again heats, is heated to 1050 ~ 1100 DEG C, jumping-up, rotates and flatten, punching, reaming; 4), the 4th fire is to 3) step obtain base material again heat, be heated to 1020 ~ 1050 DEG C, in mould circle, jumping-up is to process, depanning, and reaming is to process, control total forging ratio > 5, shove charge is warmed up to 795 DEG C, and insulation 7h, is cooled fast to 720 DEG C, insulation 5h, is down to 650 DEG C of air coolings of coming out of the stove with 20 DEG C/h cooling velocity; 5), turning groove, closing the whole footpath of cold rolling on shaping staving press, raceway, chamfering one-shot forming, finishing, buffing both ends of the surface; 6), heat treatment: preheating 800 DEG C ~ 850 DEG C, after defect detecting test, after when being less than 450 DEG C, shove charge is preheated to 600 ~ 650 DEG C of insulations, the stove putting into 950 ~ 1000 DEG C again carries out quickly heating up to 1140 ~ 1200 DEG C, 550 ~ 600 DEG C of tempering immediately after employing shrend, be cooled to 400 ~ 450 DEG C in stove after, then air cooling of coming out of the stove.
