近年来,采用合金铸铁制造光球板在轴承行业发展很快,目前,光球板成份均以Cr-Mo-Cu系合金铸铁为基础,在下述方面有变化或发展,例如,加Ni、W、B,和V加稀土,增Mn代Mo,以W代Mo等。 我厂全部采用Cr-P-Cu系合金铸铁板,制定合理的铸造工艺,从而保证了合金铸铁板有合适的硬度,高的致密性和均匀性。在未改装的 3M4630磨球机上使用本厂的光球板,磨削效率稳定在每小时5公斤,磨削11/16″球时,光球板每返修一次可加工30～60盘球,一块板可返修10次左右;而把Cr-P-Cu系铸铁板用作软磨或硬磨的固
In recent years, the use of alloy cast iron manufacturing optical ball plate in the bearing industry has developed rapidly, at present, the optical ball plate components are based on Cr-Mo-Cu alloy cast iron, in the following areas have changed or developed, for example, plus Ni, W , B, and V plus rare earth, Mn by Mo on behalf of W on behalf of Mo and so on. I plant all the Cr-P-Cu alloy cast iron plate, to develop a reasonable casting process, thus ensuring the alloy cast iron plate has the appropriate hardness, high density and uniformity. In the unmodified 3M4630 ball machine ball factory use the ball, the grinding efficiency stable at 5 kg per hour, grinding 11/16 "ball, the ball re-board processing time for each 30 to 60 balls, a The plate can be repaired about 10 times; while the Cr-P-Cu-based cast iron plate used as soft or hard grinding solid
