冷轧卷板罩式退火炉高温风机叶轮,是由Cr22Ni38、Cr20Ni14Si2及Cr20Ni10等几种材质的零件焊接而成的焊接结构。本文介绍了这些材料的焊接性能试验结果、焊条选择及焊接变彤控制等问题,并叙述了采用哈尔滨焊接研究所制造的镍317(镍基1号)焊条焊接叶轮的工艺要点。叶轮工作温度为750～800℃。
Cold-rolled bell-type annealing furnace high-temperature fan impeller, by the Cr22Ni38, Cr20Ni14Si2 and Cr20Ni10 and other materials welded parts of several welded structures. This paper introduces the welding performance test results of these materials, electrode selection and welding variable Tong control problems, and describes the use of Harbin Institute of Welding nickel 317 (nickel base 1) welding of the impeller technology points. Impeller working temperature is 750 ~ 800 ℃.
