Medium Frequency Furnace Hardware Tools, Machine Tools, Metal Workpieces, Heat Treatment Equipment

Working principle of intermediate frequency furnace:

The medium frequency electric furnace uses the medium frequency power supply to establish the medium frequency magnetic field, which makes the ferromagnetic material generate induction eddy current and generate heat, so as to achieve the purpose of heating the material. The medium frequency electric furnace uses 200-2500 Hz medium frequency power supply for induction heating, melting and heat preservation. The medium frequency electric furnace is mainly used for melting carbon steel, alloy steel, special steel, and also for smelting and temperature raising of non-ferrous metals such as copper and aluminum The equipment is small in size, light in weight, high in efficiency, low in power consumption, fast in melting and heating, easy to control the furnace temperature, and high in production efficiency.

Safe operation of intermediate frequency furnace:

1. Precautions before starting the furnace

Before starting the medium frequency electric furnace, the electrical equipment, water cooling system, inductor copper pipe, etc. must be inspected. Only when these equipment are in good condition can the furnace be started to ensure the safety of heat treatment. Otherwise, it is prohibited to start the furnace; Determine the personnel specially responsible for power transmission and furnace opening, and the responsible personnel shall not leave the post without authorization. During the work, the external conditions of the inductor and crucible must be monitored to prevent anyone from touching the inductor and cable after power transmission, affecting the normal operation of the medium frequency electric furnace or causing safety accidents.

2. Precautions after furnace opening

After the medium frequency electric furnace is opened, the charging shall be checked to avoid mixing inflammable and explosive substances. In order to prevent capping, it is strictly prohibited to directly add cold and wet materials into the molten steel, and do not add large block materials after the molten liquid is filled to the upper part; To avoid explosion accidents, it is necessary to ensure that the pouring site and the pit in front of the furnace are free of water and obstacles; During pouring, two persons are required to cooperate with each other, and the remaining molten steel can only be poured at the designated place, and can not be poured everywhere.

3. Precautions during maintenance

During the maintenance of the medium frequency electric furnace, the medium frequency generator room shall be kept clean, and inflammable and explosive articles are strictly prohibited. The furnace with excessive melting loss shall be repaired in time. During the furnace repair, iron scraps and iron oxide shall be avoided to ensure the compactness of the crucible.
