| 摘 要： | 研究经准铸态贝氏体工艺处理低碳球墨铸铁冲击磨料磨损特性。采用消失模铸造工艺，经准铸态贝氏体工艺处理后，得到了贝氏体组织。冲击磨料磨损过程以冲击变形磨损为主，兼有切削磨损和凿削磨损。通过在水泥厂应用，结果表明：磨球的成本可比低铬合金铸铁磨球降低18％，而磨球的吨水泥磨耗还不到后者的80％，破球率降低了50％。 |
| 关 键 词： | 低碳球铁 准铸态贝氏体 冲击磨料磨损 |

| Abstract: | The impact abrasive properties of as-cast bainitic low-carbon ductile iron were investigated. By controlling knock-out time, bainite structure was obtained in the as-cast low-carbon ductile iron cast with EPC process. The impact abrasive wear-off process contained the impact deformation wear as main, and also the cutting wear, as well as the chiseling wear.The application in a cement plant showed that, compared with low chromium alloyed cast iron grinding balls, the cost of as-cast bainitic low-carbon ductile iron balls could be decreased by 18%, the wear off weight of grinding balls per ton cement was reduced by more than 20%, and the broken ball rate was reduced by 50%. |
| Keywords: | low-carbon ductile iron quasi as-cast bainitie impact abrasive wear off |
