摘要
介绍回转窑轮带裂纹修复补焊工艺。实践证明,通过采取焊前预热,CO2tAr气体保护焊和林肯药芯焊丝,焊后退火及焊接过程中多次渗透探伤和超声波探伤等焊接工艺,可以保证补焊后轮带达到预期使用效果。
The repairing welding process for the cracks in rotary kiln was introduced.Practices prove that,taking the process measures,such as preheating before welding,CO2 gas shielded arc welding and Lincoln flux cored wire,annealing after welding and multiple penetration testing and ultrasonic exploration welding process,can guarantee to achieve the desired effect after welding in rotary kiln.
