【摘要】 简要分析了浆体输送管道的磨损机制以及材料类型对抗磨损性能的影响,分析得出浆体输送管道的磨损以冲蚀磨损为主,硬度不是影响材料抗冲蚀能力的唯一因素,而在保证一定硬度的前提下,增加材料的塑韧性和微观组织的协调变形能力,有利于增加材料的抗冲蚀能力。磨损试验对比表明,Mn系贝氏体钢具有较好的抗磨损性能,有利于提高浆体输送管道的使用寿命,降低综合成本,具有十分广阔的应用前景。更多还原

【Abstract】 The wear mechanism of the pipe used for slurry transportation and influences of pipe material on its wear resistance property were briefly analyzed. The analysis results showed that the wear of the pipe used for slurry transportation is mainly composed of flush erosion and the material hardness was not the only factor affecting the flush erosion resistance property. Given a certain hardness, the increase in plasticity and malleability of the pipe material as well as the rise in compatible deformation of the material microstructure were contributed to improving the flush erosion resistance property of the material. Wear tests and contrast indicated that Mn-series bainite steel possessed excellent wear resistance property that was helpful for improving the lifespan of the pipe used for slurry transportation and reducing overall cost, obviously it had broad application prospect.更多还原
