摘　　要：阳极导杆组是铝电解槽阳极的金属结构件,在铝电解槽生产过程中,阳极导杆组会因为导杆缺陷、焊接缺陷、钢爪头缺陷、外观几何尺寸、表面质量等质量因素下线,下线后的导杆组经维修合格后进入下一个循环周期。钢爪头的修复是导杆修理过程中的重要环节,原有修复工艺是将报废的钢爪头切割,锯切新钢爪头,对结合面开坡口并打磨,再组对焊接。这种工艺生成的焊缝压降较大,焊接质量难以保证。钢爪头半自动熔铸技术,成功的解决了阳极钢爪头焊接的难题,有效的提高了焊接质量,降低了焊缝压降,提高了劳动效率,降低了维修成本。The anode guide rod group is a metal structural component of the anode in an aluminum electrolysis cell.During the production process of the aluminum electrolysis cell,the anode guide rod group may be taken offline due to quality factors such as guide rod defects,welding defects,steel claw head defects,appearance geometric dimensions,and surface quality.After being taken offline,the guide rod group is repaired and qualified before entering the next cycle.The repair of the steel claw head is an important part of the guide rod repair process.The original repair process was to cut the scrapped steel claw head,saw the new steel claw head,groove and polish the joint surface,and then assemble and weld it.This process generates a significant pressure drop in the weld seam,making it difficult to ensure welding quality.The semi-automatic casting technology of steel claw head has successfully solved the problem of anode steel claw head welding,effectively improving welding quality,reducing weld pressure drop,improving labor efficiency,and reducing maintenance costs.
