The intermediate frequency furnace is mainly composed of a ruthenium made of refractory material in the power source, the induction coil and the induction coil. The crucible contains a metal charge, which is equivalent to the secondary winding of the transformer. When the induction coil is connected to the AC power source, an alternating magnetic field is generated in the induction coil, and the magnetic flux cuts the metal charge in the crucible, and the crucible is generated in the furnace. The induced electromotive force is characterized by a single turn and is closed because the charge itself forms a closed loop. Therefore, an induced current is simultaneously generated in the charge, and when the induced current passes through the charge, the charge is heated to cause it to melt.

The intermediate frequency electric furnace uses the intermediate frequency power source to establish an intermediate frequency magnetic field, so that the induced eddy current inside the ferromagnetic material generates heat and reaches the purpose of heating the material. The medium frequency electric furnace adopts 200-2500Hz intermediate frequency power supply for induction heating, smelting and heat preservation. The medium frequency electric furnace is mainly used for melting carbon steel, alloy steel, special steel, and can also be used for melting and warming of non-ferrous metals such as copper and aluminum. The equipment is small in size and weight. Light, high efficiency, low power consumption, fast melting and heating, easy control of furnace temperature and high production efficiency.

The intermediate frequency furnace needs to be sintered in its maintenance. It should be noted that if the equipment is used once, the equipment should be lining. In operation, the acid lining is more advantageous for the protection of the furnace body.

When you are lining, prepare the materials you want to use. A protective layer is then placed on the inner wall of the furnace to ensure isolation of the inner induction coil. In addition, a one-time molded household is placed in a low temperature fire for baking, and then waits for tens of minutes, which will condense into a solid body. There is almost no requirement in terms of hardness, as long as the operations of melt agitation and feeding are performed, it will not be broken.

This is followed by a sintering operation, which is continued to bake for 24 hours in a slow temperature rise until it is completely condensed and solidified. The user must correctly complete the above two processes because they are the basis for ensuring the long-term use of the intermediate frequency electric furnace.

In addition, in operation, in general, the system water flow must first be checked. Check for leaks. Keep a strict work style when working: Avoid spraying the medium frequency furnace with your fingers or body; once you find that the furnace body is red, you should cut off the power immediately; if you find that the lining is broken, you should immediately blast the lining.
