我厂在钢球生产过程中使用的锉球板如图所示。要求锉面平整,耐磨。由于我厂条件有限,无法用轴承钢或渗碳钢制造。为解决生产问题,我们试用了ZG45钢渗碳制造锉球板,经过几年试制,取得了良好效果,其锉磨使用寿命与高频淬火的轴承钢锉相当。其生产工艺如下:工件经车削和刨齿加工后装入渗碳箱,压实后用黄土密封,然后加热渗碳。渗剂为:CaCO_35%+BaCO_313～17%+SiO_21.5%,其余为木炭。渗碳淬火工艺及其结果如表所示。为防渗碳后二次
I plant in the ball used in the production process of the file as shown. Requires filing flat, wear-resistant. Due to the limited conditions of our factory, it can not be made of bearing steel or carburized steel. In order to solve the production problem, we tried ZG45 steel carburizing manufacturing file ball, after several years of trial production, and achieved good results, the service life of its filing and high frequency quenching bearing steel file quite. The production process is as follows: The workpiece after turning and planing teeth into the carburizing box, compacted with loess seal, and then heated carburizing. Penetration agent: CaCO_35% + BaCO_313 ~ 17% + SiO_21.5%, the rest is charcoal. Carburizing quenching process and the results shown in the table. To prevent carburizing after two
