简析低温时效工艺对液压支架结构件的影响

Brief Analysis of the Effect of Low Temperature Stress Relief Process on the Structural Parts of Hydraulic Support

随着国内工业技术水平的提高,水力支撑结构件的使用领域越来越广泛。液压支撑构件的焊接技术在强化其功能的同时,也存在着抗拉强度低、残余应力不足、抗冲击性能差等缺陷。采用低温时效技术,对水力支撑结构件的焊接接头抗拉强度、抗冲击强度、硬度和残余应力等都有较大的改善。将低温时效技术的应用作为研究的出发点,对比了三种不同工艺的影响,总结出了低温时效技术的优势以及它对液压支架结构件的影响。希望可以为今后的研究带来一些帮助。

With the improvement of domestic industrial technology,the use of hydraulic support structures is becoming increasingly widespread.The welding technology of hydraulic support components not only enhances their functions,but also has defects such as low tensile strength,insufficient residual stress,and poor impact resistance.Using low-temperature stress relief technology has greatly improved the tensile strength,impact strength,hardness,and residual stress of welded joints of hydraulic support structures.Taking the application of lowtemperature stress relief technology as the starting point of the study,the effects of three different processes were compared,and the advantages of low-temperature stress relief technology and its impact on hydraulic support structures were summarized,hoping it can bring some help for future research.
