Reasons and Solutions for Blocking of Induction Coils in Electric Furnace

Author : Hongteng Time: 2022-04-02

When using the furnace, sometimes the induction coil is blocked, which affects the production capacity of the entire production line. Today, Hongteng editor will analyze the reasons and solutions for the blocking of the induction coil of the furnace.

There are two common reasons.

One is a foreign body blockage. The cooling water source used by the user sometimes directly extracts the river water as the cooling water for the electric furnace. There are many foreign objects in the river water. Therefore, when extracting and using the river water, the foreign objects can easily block the induction coil, resulting in blocked or blocked waterways.

Another is limescale clogging. The water source used for cooling is basically natural water with relatively high hardness, and the smelting furnace will generate high temperature when it is working. At this time, when water is used for cooling, it is easy to produce scale attached to the inside of the induction coil copper tube. The composition of scale is basically calcium carbonate and magnesium hydroxide. If it is not treated for a long time, these deposits will become more and more hard. Finally, the sediment will not only block the coil and cause the water to flow unsmoothly, but also affect the overall performance and service life of the electric furnace.

So is there any solution to the blockage of the induction coil of the electric furnace?

1. Before the cooling water source enters the furnace body, we can install a filter screen to filter out larger foreign objects in the river water.

2. If there is a small foreign body blockage, and the blockage position is not too deep, we can try to use iron wire to pass into the copper tube of the induction coil, and hook out the sundries inside.

3. When the scale and other oxides block the induction coil, we can inject dilute sulfuric acid to make the oxide and dilute sulfuric acid react chemically to eliminate the scale. Don’t worry about the induction coil, copper and dilute sulfuric acid will not react.

Using these methods after blockage will not harm the induction coil, nor will it affect the use of the smelting furnace. Users can use it as a reference to solve the problem of coil blockage of the furnace. If it still can’t be solved, you need to contact relevant professionals.

This is what we have compiled for the knowledge of induction coils for smelting electric furnaces. Welcome to Luoyang Hongteng, let us solve more furnace repair doubts for you.
