摘　　要：文章选定包钢稀土耐磨钢板BTNM450和国外某厂家生产的NM1^(#)耐磨钢板两种试验材料,从显微组织、硬度、耐磨性能等方面进行对比分析。研究结果表明,包钢稀土耐磨钢板BTNM450的磨损量为0.3900 g,明显低于NM1^(#)耐磨钢板的磨损量。与未添加稀土元素的耐磨钢板BTNM450-NORE相比,添加稀土元素后包钢稀土耐磨钢板BTNM450的磨损量降低20.9%。NM1^(#)耐磨钢板截面上的硬度分布不均匀,包钢稀土耐磨钢板BTNM450的硬度沿截面厚度方向的变化不明显,具有优良的耐磨性能。In this paper,such aspects as microstructure,hardness and wear resistance of rare earth wear resistant steel plate BTNM450 of Baotou Steel and NM1^(#)wear resistant steel plate produced by a foreign manufacturer are selected to be compared and analyzed.The study results showed that the wear extent of rare earth wear resistant steel plate BTNM450 of Baotou Steel was 0.3900 g,which was significantly fewer than that of NM1^(#)wear resistant steel plate.Compared with the wear resistant steel plate BTNM450-NORE without adding rare earth elements,the wear extent of rare earth wear resistant steel plate BTNM 450 of Baotou Steel after adding rare earth elements is reduced by 20.9%.The hardness distribution on section of NM1^(#)wear resistant steel plate is not uniform and hardness of rare earth wear resistant steel plate BTNM450 of Baotou Steel does not change significantly along the direction of section thickness,which is with excellent wear resistance.
