摘要
轧机除鳞集管结构复杂、焊缝密集、焊缝探伤要求的比例高、结构形位公差控制严。在生产中,运用焊接技术理论并结合多年的实际经验,经过综合分析制定出了一套正确的制造工艺,使生产的三个除鳞集管的质量均较好地满足了技术要求。
For the descaling header in H section mill, its structure of is complex, the welding is closely spacedt the requiring crack detection rate for weld is high, the requiring form tolerances and locations tolerance are strict. During production, based on the welding technical theory and practical experience, the proper manufacturing process has been made by comprehensive analysis , and the quality of three produced descaling header has met better the technical reguirements.
