摘　　要：用正交试验法探讨了自保护硬面药芯焊丝药芯粉中金红石、氟化物、硅灰石、氧化锆和镁砂对焊接飞溅的影响,对含氮自保护硬面药芯焊丝药芯粉的最佳配比进行了优化。结果表明:随着药芯中氟化物、氧化锆含量的增加,焊接飞溅增大;随着药芯中金红石、硅灰石和镁砂含量增加,焊接飞溅减少;当金红石、氟化物、氧化锆、镁砂和硅灰石质量分数分别为8.0%,4.0%,4.0%,5.0%和2.0%时,含氮自保护硬面药芯焊丝焊接工艺性能最佳。Effects of flux compositions of self-shield hardfacing flux-cored wire such as rutile, fluoride, wollastonite, zircite and magnesia on spatter were studied by orthogonal experimental design, an optimal mixture ratio of varied flux powders for nitride alloyed self-shield hardfacing flux-cored wire was got. With increasing contents of fluoride and zircite in the flux, the spatter increase. But with increasing contents of futile, wollastonite and magnesia, the spatter decrease. When the flux contained 8. 0%of futile, 4. 0% of fluoride, 4.0%of zircite, 5. 0% of magnesi and 2. 0% of wollastonite, the welding process properties are optimal.
