摘要 回转窑用大齿圈为铸造成型,其质量是QCP控制的重中之重。大齿圈不仅要使用超声波无损检测(UT)对其内部铸造质量进行严格检测,而且在成品时需使用磁粉无损检测(MT)对其表面进行检测。UT检测不合格时,通常齿圈不可使用,UT检测合格但MT检测不合格,尤其是齿面存在疏松、夹渣、微裂纹等缺陷而导致MT检测不合格时,对缺陷进行打磨清理干净即可。此时的问题是,表面外观(VC)检测不合格。为了解决该问题,一种表面冷焊技术被运用到齿面修复上,该技术只是针对齿圈外观进行“美化”修复,对齿圈本身的性能不会产生任何的影响。

Abstract: The quality of girth gear was always the top priority in Quality Control Planning which was formed by casting and used for rotary kiln. The inner quality of girth gear was not only strictly tested by the ultrasonic nondestructive testing (UT), but also the surface quality was tested by magnetic particle nondestructive testing (MT) in the finished. UT unqualified, the girth gear failed. UT qualified, but MT unqualified, especially loose, slag and micro cracks on tooth surface caused MT unqualified, the defect could be polished cleanly. At the same time, VC unqualified, in order to solve this problem, a surface cold welding technology was applied to the teeth on the girth gear technology only for the appearance "beautifying". Repair performance of the gear ring itself did not affect.
Key words:  rotary kiln    girth gear    quality    UT    MT    cold welding repair
