Process for quickly repairing copper tube burn-through of intermediate frequency furnace inductor
When the induction coil is severely ignited, a arc will be formed, and a severe arc will cause the copper tube to be broken at the arcing portion. In another case, after the lining is burned through, the iron overflow causes the copper platoon to burn through. After the copper platoon is burned, the cooling water overflows and must be immediately repaired. Since the copper bars are installed in the furnace shell, the welding repair is inconvenient and needs to be removed and removed during the repair. Usually, the copper platoon repair process wastes at least one lining, which is more time consuming. Here is a sticky method for everyone to save maintenance costs.
For the first reason caused by the copper row burn-through, the furnace can be temporarily shut down, and the copper piece of 1 ~ 2mm thick is cut into small pieces, the area should be slightly larger than the area of the copper discharge crack, and then removed by a saw blade or a hand grinding wheel. The residue of the copper platoon is burned and cleaned with sandpaper. The FCR copper crack fast repairing agent is quickly mixed with the curing agent, and the trimmed copper sheet is stuck in the copper row cracking. After a few minutes, the FCR is solidified. The high copper bond strength can be re-opened at this time.
For the second reason caused by the copper row burn-through, the repair process is as follows: tilting the furnace iron → stopping the furnace → repairing the furnace lining → copper row bonding + opening furnace. This repair process also saves a lining and a large amount of man-hours and oven power compared to conventional weld repairs.
