Method of repairing leakage of induction furnace coil

中频电炉在运行过程中，感应器加热线圈作为最大的发热体，需要独立水路来冷却，以确保出水温度低于55度。然而，由于长期使用导致的腐蚀或铜管本身的制造缺陷，线圈容易出现漏水状况。以下是中频电炉线圈漏水修补的详细方法：

During the operation of the induction furnace, the induction coil heating coil, as the largest heat-generating, requires an independent water circuit for cooling to ensure that the water outlet temperature is below 55 degrees. However, due to corrosion caused by long-term use or manufacturing defects the copper tube itself, the coil is prone to water leakage. Here is a detailed method for repairing a medium frequency electric furnace coil which  is leaking water:

1 查明漏水部位：1 Identifying Leakage Location:

首先，需要准确查明漏水部位，确定漏点是在线圈的两侧面、内侧还是外侧。

Firstly, it is necessary to accurately identify the leakage location and determine whether the leakage point is on the two sides of the coil, the inner, or the outer side.

根据漏水部位的修补难易程度，决定具体的修补方法。

Based on the difficulty of repairing the leakage location, the specific repair method is determined.

2 停炉修理与安全措施： 2 Shutdown Repair and Safety Measures:

原则上，中频电炉漏水修补需要停炉修理，严禁带电作业，以确保安全。

In principle, medium frequency electric furnace leakage repair requires shutdown repair, and it is strictly prohibited to work with electricity to ensure safety.

漏水部位修补可采取紫铜焊接补漏或者粘贴剂补漏，具体方法需根据漏水情况选择。

The repair of the leakage location can done by welding with red copper or by using an adhesive, and the specific method needs to be chosen according to the leakage situation.

3 排水与避免气泡：  3 Draining and Avoiding Bub:

在补漏之前，需将线圈内的水全部放掉，以避免产生气泡影响补漏效果。

Before patching, all the water in the coil must be drained to avoid the generation of bubbles affecting the patching effect.

4 线圈内部漏水修补： 4 Internal Leakage Repair the Coil:

若线圈内部漏水，需砸掉炉衬以露出线圈铜管上的漏水部位。

If there is internal leakage in the coil, it is necessary to smash the furnace lining to expose the leakage location on the copper tube of the coil.

如线圈温度过高，需先将其降至常温后再进行补漏修补。

If the coil temperature is too high, it is necessary to reduce it to room temperature before patching and repairing.

5 根据漏水情况选择修补方法：

5 Selecting the Repair Method Based on the Leage Situation:

根据漏水点孔眼的大小、腐蚀程度或击穿情况，采取不同的修补方法。

According to the size of the hole at the leakage point, the degree of corrosion, or the situation of perforation, different repair methods are adopted

如果孔眼过大，原则上应采取紫铜焊接修补方法。

If the hole is too large, the principle should be to use red copper welding repair method.

如果只是渗水裂纹，可采取薄紫铜片粘贴的方法进行修补。

If it is just a seepage crack, it can be repaired pasting a thin red copper sheet.

6 粘贴法修补的注意事项：6 Precautions for Patching Repair:

使用粘贴法修补的漏水线圈，在使用中严禁缺水，且不可使线圈铜管升温过高。

For the coil that has been repaired with the pasting method, it is strictly to lack water during use, and it is not allowed to make the coil copper tube too hot.

过高的温度会影响粘贴补漏的使用寿命，甚至可能导致漏点重新开裂。

Excessive temperature will affect the service life of the pasting repair and may even cause the leakage point to crack again

7 打压试验与通水试验： 7 Pressure Test and Water Test:

有条件的，应在线圈修补过后进行打压试验，以确保修补效果。

If possible, a pressure test should be conducted after the coil is repaired ensure the repair effect.

没有条件的，需做3公斤水压的通水试验10分钟，仔细观察修补处是否有水迹渗出。

If not possible, a water pressure test of 3 kilograms should be conducted for 10 minutes to carefully observe whether there is any water seeping out from the repaired part.

通过打压试验或通水试验，确保线圈漏水修补完好无误。

By conducting a pressure test or a water test, it ensures that the coil leakage repair is perfect.

在修补过程中，务必遵循安全操作规程，确保人员和设备的安全。同时，根据漏水情况选择合适的修补方法，并严格按照修补步骤进行操作，以确保修补效果。

During the patching process, it is imperative to follow the safety operation procedures to ensure the safety of personnel and equipment. At the same time, select the appropriateing method according to the leakage situation and strictly follow the patching steps to ensure the patching effect.
