我矿φ4000×1400湿式自磨机簸箕板,因长期使用,螺孔处磨穿,而其它部位还可以继续使用。但这使衬板固定不住,还往外甩矿浆,衬板螺栓也经常折断,直接影响生产。要更换全部簸箕板不但检修工作量大而且经济损失也大。针对这种情况,我们采用结506焊条,用哈巴粉做皮下过渡的办法焊接修补簸箕板,收到了较好的效果。自磨机簸箕板材质为QT45-5,重260kg,共18块,每块578元。该件安装在磨机筒体上,不易拆卸,更换时,其它的衬板也得拆除,然后重新安装,故需几天的时间才能完成。每块 I mine φ4000 × 1400 wet self-grinding machine dustpan plate, due to long-term use, worn at the screw hole, while other parts can also continue to use. But this makes the liner can not hold, but also throw pulp, liner bolts are often broken, a direct impact on production. To replace all the dustpan plate not only overhaul the workload and the economic loss is also large. In view of this situation, we use the knot 506 electrode, with the way to make subcutaneous Habasitiao welding repair patchpan, received good results. Since the mill dustpan board material QT45-5, weight 260kg, a total of 18, each 578 yuan. The piece mounted on the mill barrel, not easy to disassemble, replacement, the other liner has to be removed, and then re-install, it takes a few days to complete. Each piece
