高炉上紫铜与16MnR异种金属的焊接

阐述了紫铜与16Mn R钢异种金属材料焊接在柳钢3#高炉紫铜水冷壁修复中的应用。针对紫铜与16Mn R钢异种金属材料的焊接特点,在制造车间将新紫铜冷却水箱与炉壳等厚的16Mn R钢板(δ=40 mm)焊接制成一个组合工件,在高炉施工现场由组合工件与高炉炉壳直接焊接。加工适当的焊接坡口,选择合理的焊接工艺,成功解决了紫铜与16Mn R钢异种金属材料的焊接问题,按质、按期完成紫铜冷却水箱的更换,获得甲方的一致好评。

Welding of red copper and 16MnR dissimilar materials on the blast furnace

The welding of red copper and 16MnR steel dissimilar metal materials applied in the repair of red copper water-cooling wall on 3# BF.According to the welding characteristics of red copper and 16MnR steel dissimilar metal materials,the new red copper cooling water tank and 16MnR steel plate with same thickness of the furnace shell (δ=40 mm) are welded into a assembly workpiece in workshop,and then the workpiece are direcdy welded with the blast furnace shell on site.Processing proper welding groove and choosing reasonable welding technology successfully solve the welding problems of red copper and steel 16MnR material.This method is applied in the repair of red copper water-cooling wall of blast furnace,and the red copper cooling water tank is replaced on time with good quality,and a favorable reception is given by Party A.
