摘　　要：为解决竖炉齿辊卸料装置中水梁底部焊缝开裂漏水的原因。采用冷压成型结构件代替原有底部焊接水梁，以冷弯过渡R30圆角代替原有90°焊接角，经装机使用，效果十分明显，使用寿命达到2年，比原设计焊缝结构提高了3倍。In order to eliminate the reasons leading weld failure water leakage at the bottom of water beam in the toothed roll charging equipment for vertical furnace, cold - pressing - shaped structural parts are used to replace original bottom welded water beam with cold bended transient R30 round angle replacing the original welded 90° right angle. The practical using results shows that the service life can reach up two years, being 3 times of that of the original designed welding seam structure, obtaining very good results.
