Causes and Solutions of Induction Furnace Earth Leakage

Reasons for Induction Furnace Earth Leakage

A common accident in an induction furnace block is a leak through the hearth. If an accident occurs, if no measures are taken, it will cause the copper tube of the coil to rupture, and the molten iron and coolant will explode. reason:

1. The quality factor of the materials used in the construction of the furnace: generally, the lining material of quartz acid is used. The silicon content of quartz sand and quartz powder should be more than 99.5%, in the form of oily crystals, transparent and free of impurities. Generally, high-purity quartz sand (silicon content 99.85%, hardness 8, density 2.65, refractoriness 1850 degrees) is used.

2. Binder factors used in furnace construction: traditional furnace construction methods generally use boric acid as a binder. Boric acid has both advantages and disadvantages: the advantage is that it adheres quickly at low temperatures, generally starting at 600-700 degrees; the disadvantage is that it is not resistant to high temperatures and erosion. Under high-temperature conditions, boiling will occur in the lower part of the furnace wall, and the number of furnaces used will be greatly reduced. It is recommended to use boric acid as a binder because boric acid has the characteristics of high-temperature bonding, high melting point, high-temperature resistance, and corrosion resistance.

Induction Furnace Earth Leakage Solution Technical Solution

In order to overcome the shortcomings of high coil maintenance cost and long maintenance cycle of the induction coil, a method to quickly solve the leakage and ignition of the induction coil of the induction heating furnace can eliminate the phenomenon of leakage and ignition of the induction coil in a short period of time. The induction coil can be put into use again in a short time, and at the same time, the overall service life of the induction coil can be greatly improved.

The induction furnace earth leakage solution technical solution is a method for quickly solving the induction coil leakage and ignition of the induction heating furnace, comprising the following steps:

1. First confirm the leakage and ignition parts of the induction coil, and then remove the guide rail on the induction coil;

2. Remove the leakage on the induction coil and the damaged insulating material on the ignition part to expose a section of copper tube wound on the induction coil;

3. Re-insulate the exposed section of copper pipe;

4. Apply a layer of refractory mud on the surface of the newly insulated part of the induction coil;

5. Reinstall the guide rail on the induction coil that has been coated with refractory mud;

6. Use the residual heat of the heated workpiece to dry the newly applied refractory mud.

This induction furnace earth leakage solution technical solution quickly solves the technical solution of the induction coil leakage and ignition method of the induction heating furnace. It does not need to destructively repair the entire induction coil, as long as the leakage and ignition parts are partially repaired, it can be repaired Eliminate the phenomenon of leakage and ignition of the induction coil in a short period of time, so that the induction coil can be put into use again in a short period of time, and at the same time, the overall service life of the induction coil can be greatly improved.

This induction furnace earth leakage solution has the characteristics of simplicity, reasonableness, speed, and practicality. It can be repaired at the user terminal, and it is very practical in the actual production of the enterprise. As long as the induction coil is not completely damaged, the present invention can be used almost method has great economic significance.
