我厂有一台75千瓦电极盐浴炉,原电极冷却系统是在每个电极上钻一φ20毫米的冷却孔,上下分别焊进出水管。冷却水由三个进水管流进,经三个出水管流入集水器再流到下水道,冷却效果不好,冷却水溅得满地都是。现改为在电极冷却孔一侧再扩长60～80毫米,在冷却槽上方焊一带上水管的铁板,下水管位置不变,最后把三个电极的冷却水管串联 I plant a 75-kilowatt electrode salt bath furnace, the original electrode cooling system is drilled in each electrode φ20 mm cooling holes, respectively, up and down into the water pipe. Cooling water from the three inflow into the water through the three pipes into the catchment and then to the sewer, the cooling effect is not good, cooling water splashed all over. Now changed to the side of the electrode cooling holes and then expanded 60 to 80 mm, welded in the top of the cooling tank with a pipe on the iron, the water pipe position unchanged, and finally the three electrodes of the cooling water pipe in series
