| 摘 要： | 对硅锰铸钢添加稀土后的铸态组织、断口、热处理组织进行了观察分析，认为硅锰铸钢中添加稀土后，对铸态组织、夹杂物、淬火组织产生良好的影响，从而使铸钢的冲击韧度有较大幅度的提高。在保证硅锰铸钢淬火、低温回火后，吼值大于200KJ／m^2的前提下，可提高硅锰铸钢的含碳量，使其耐磨性提高，为扩大硅锰铸钢的应用范围创造了有利条件。

| Abstract: | The as-cast structure , fracture and structure of heat treatment of Si-Mn steel casting with rare earth elements were analyzed.The results show that, putting rare earth in Si-Mn steel has a good influence on as-cast structure,impurity and quenching structure, can improve the impact toughness. In the precondition of quaranting ak>200kJ/m2 after quenching and tempering at low temperature, the anti-wear property of Si-Mn steel can improve by increasing carbon content, which extends the use of Si-Mn steel . |
