| 摘 要： | 利用改造的MLD-10型冲击腐蚀磨损模拟试验机,研究了3种矿山湿式磨机衬板钢在石英砂酸性介质中的冲击腐蚀磨损行为。研究表明,在同样的模拟工况条件下,新研究开发的低碳高合金钢比高锰钢、中碳合金钢具有更佳的耐冲击腐蚀磨损性能,随着时间的延长,低碳高合金钢的优越性越明显。并通过对试样表面磨损形貌的观察分析,发现低碳高合金钢以冲击磨损为主,高锰钢以冲蚀为主,而中碳合金钢则是严重的冲蚀磨损。

| Abstract: | In order to study the impact-corrosion-abrasion behavior of the steel used in the liner of wet-grinding machines applied in mines,an experiment was carried out using a modified MLD-10 tester to study the behavior of three kinds of steel in quartzite slurry. The study results show that under the same simulative working conditions, the impact and corrosive wear resistence of the low carbon high alloy steel is better than that of both the high manganese steel and the medium carbon alloy steel,and that with the increase of the test time, the low carbon high alloy steel shows marked superiority. By observation and analysis of the worn surfaces of the samples,it is found that the wear mechanism of the low carbon high alloy steel is impact wear,that impact-corrosion is the main wear form of the high manganese steel, and that the medium carbon alloy steel is characterized by the heaviest impact-corrosion wear. |
