1982年,华山冶金车辆修造厂用堆焊法修复了济南钢铁厂的吊轴磨耗深度已达24mm的5号65吨铁水罐,经电磁和超声波探伤,确认堆焊质量合格,又经六个多月的承载运行,未发现变形及裂纹,其磨耗程度与新投入使用的4号罐相同。长期以来,用堆焊法修复铁水罐吊轴被视为禁区,而整体更换罐臂,则许多中小企业又受到条件限制,因此,铁水罐吊轴的堆焊修复为中小企业找到了一种简便的就地修复方法。
In 1982, Huashan Metallurgical Vehicle Repair Factory repaired the steel mill in Jinan Iron and Steel Plant Shaft wear depth has reached 24mm on the 5th 65 tons of hot metal tank, electromagnetic and ultrasonic testing, to confirm the quality of welding surfacing, but also by more than six The bearing operation of the month, did not find the deformation and the crack, the degree of abrasion and the new tank 4 the same. For a long time, the use of surfacing method to repair the hot metal shaft is considered as a forbidden area, and the overall replacement of the cantilever arm, many small and medium enterprises are subject to conditions, therefore, the hot metal welding repair hanger shaft found a simple for SMEs In-place repair method.
