冶金矿山湿式磨机衬板钢冲击腐蚀磨损行为的研究

利用改造的MLD - 10型冲击腐蚀磨损模拟试验机 ,研究了三种冶金矿山湿式磨机衬板钢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 ,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

Behavior of corrosion - abrasion of liner of wet - grinding machine in metallurgical industry

The test was carried out using a modified MLD-10 tester. The test methodology very well simulates the working condition of metallurgical industry. The behavior of corrosion-abrasion of the liner of wet-grinding machine in metallurgical industry were discussed. The results show that under the same conditions, the corrosion rate and the wear loss of the low carbon high alloy steel is better than the high manganese steel and the medium carbon alloy steel. And with the test time increased, the superiority of the low carbon high alloy steel was well illuminated. The worn surfaces of the three steels show that the mechanism of the low carbon high alloy steel is impact abrasion, the high manganese steel is impact-corrosion wear, and the medium carbon alloy steel is the heaviest impact-corrosion wear.
