大型水泥回转窑托辊的焊接工艺研究

Research on Welding Process of Turn-kiln Supporting Roller

研究了回转窑托辊的焊接工艺,结合拉伸和冲击试验、弯曲角测试、接头金相组织和断口分析,进行了焊接工艺评定。结果表明,试样接头组织正常,接头抗裂性能和综合力学性能与母材相当,焊接工艺基本可行。

The welding process of the turn-kiln supporting roller was studied. By means of tensile and impact and curved angle test, microstructure and fracture analysis, the evaluation of the welding process was made. The results show that the microstructur~ of welding joint is normal, the welding joints and based metal are well-matched in anti-cracking and mechanical properties. The welding processes fit for the roller.
