| description | The invention relates to a manufacturing method of a high-quality long-service-life core roller of a ring rolling machine, and belongs to the technical field of core roller machining. The core roller forging material adopted by the invention mainly comprises the following components: 0.40-0.44 wt% of C, 0.20-0.30 wt% of Si, 0.60-0.80 wt% of Mn, 0.95-1.25 wt% of Cr, 0.20-0.30 wt% of Mo, less than or equal to 0.015 wt% of P, less than or equal to 0.008 wt% of S, less than or equal to 0.05 wt% of Cu, less than or equal to 0.008 wt% of Ti, less than or equal to 0.01 wt% of V, less than or equal to 0.20 wt% of Ni, 0.020-0.040 wt% of Al, less than or equal to 0.0080 wt% of N, less than or equal to 18ppm wt% of [O] and less than or equal to 2ppm wt% of [H]. After the core roller is formed according to the forging method provided by the invention and the heat treatment method provided by the invention is adopted, the service life of the produced core roller product reaches that 28 times of ring rolling are not broken |
