摘要
为提高料钟、料斗的耐磨性能和密封性能 ,采取了在料钟、料斗结合面上堆焊一层硬质合金 TDGC-1的方法。选择软芯堆 667焊条 ,堆焊层为索尔玛依特合金 ,可提高其抗裂性能 ;同时在两层钢板中间加塞石棉保温罩 ,保证了焊接质量。堆焊后的料钟、料斗使用寿命是堆焊前的
For increasing the resistance to wear and sealing property between bell and hopper of blast furnace the method overlaid welding a lay of TDGC-1 hard alloy on the matching surface of bell and hopper is used.After overlay welding,the service life of bell and hopper is increased by a factor of 5 than before.
