一种快速修复中频炉感应器铜管烧穿的工艺

感应线圈打火严重时会将形成拉弧，严重的拉弧会导致铜管在拉弧部位被击穿。另一种情况是在炉衬被烧穿后，铁液外溢引起铜排烧穿。 铜排烧穿后造成冷却水外溢，必须立即停炉修复。由于铜排安装在炉壳内，焊补不便，修复时需拆卸取出。通常铜排修复工艺至少要浪费一个炉衬，还比较费时，下面就为大家介绍一种粘补法，为大家节约维修成本。 

对第一种原因引起的铜排烧穿，可暂时停炉，同时将1～2mm厚的铜片剪成小块，其面积应稍大于铜排烧裂口面积，然后用锯片或手砂轮清除铜排烧穿处的残渣，并用砂纸打磨干净，迅速将FCR铜裂纹快速修补剂与固化剂混合，把修剪好的铜片在铜排烧裂处粘好，几分钟后FCR固化，即可形成很高的铜排粘结强度，此时就可以重新开炉了。

 对第二种原因引起的铜排烧穿，修复工艺过程如下：倾炉出铁→停炉→维修炉衬→铜排粘补→开炉。该修复工艺较传统的焊补修复也节省了一个炉衬及大量工时和烘炉电力。

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.
