摘　　要：选用不同的电流频率对新型Q235La0.1 Ti0.1建筑钢结构材料进行了高频感应热处理。对材料进行显微组织、力学性能和耐磨损性能的测试与分析,结果显示,材料的力学性能和耐磨损性能,随电流频率增加先提高后降低。与150 kHz电流频率相比,采用200 kHz电流频率时的材料抗拉强度增加18%,屈服强度增加11%,断后伸长率增加11%,磨损体积减小56%;采用250 kHz电流频率时的材料抗拉强度减小5%,屈服强度减小4%,断后伸长率减小5%,磨损体积增大21%。优选材料高频感应热处理的电流频率为200 kHz。Different current frequencies were chosen to carry out high frequency induction heat treatment of new Q235La0.1Ti0.1 construction steel structure material. Test and analysis of microstructure, mechanical properties and wear resistance of the material were carried out. The results show that mechanical properties and wear resistance of the material first increase and then decrease with the increase of current frequency. Compared with 150 kHz current frequency, tensile strength, yield strength, break elongation of the material using 200 kHz current frequency increase by 18%, 11%, 11% respectively and wear volume reduces by 56%; tensile strength, yield strength, break elongation of the material using 250 kI-Iz current frequency reduce by 5%, 4%, 5% respectively and wear volume increase by 21%. The optimal current frequency of high frequency induction heat treatment of the material is 200 kHz.
