The right way to operate your induction melting furnace safely

Induction melting furnace is a kind of equipment for casting and forging and thermal processing. It consists of frequency conversion device, furnace body and furnace front control. It converts three-phase power frequency AC power to DC power and outputs it through inverter circuit. After the conversion of the single-phase intermediate frequency AC power, the heat treatment of the metal is realized according to the principle of electromagnetic induction. However, in order to ensure the efficient operation of the intermediate frequency furnace, it is necessary to operate it safely. The following section describes how to operate it safely.

I. Precautions before opening the furnace

Before starting the induction melting furnace, it is necessary to check the electrical equipment, water cooling system, inductor copper tube, etc. Only when these equipments are in good condition can the furnace be opened to ensure the safety of heat treatment, otherwise it is prohibited to open the furnace; Identify the person responsible for power transmission and furnace opening, and the responsible person must not leave the post without authorization. During the work, the external conditions of the inductor and crucible must be monitored to prevent someone from touching the sensor and cable after power transmission, which will affect the intermediate frequency electric furnace. Normal operation or safety accident.

Notes after opening the furnace

After the induction melting furnace is opened, when charging, the inside of the furnace should be inspected to avoid mixing with flammable and explosive materials. In order to prevent the phenomenon of capping, it is strictly forbidden to directly add cold and wet materials into the molten steel, and do not add large-volume blocks after the molten liquid is filled to the upper part; in order to avoid explosion accidents, it is necessary to ensure the pouring site and furnace There is no stagnant water and no obstacles in the front pit; while two people need to cooperate to carry out the pouring, the remaining molten steel can only be poured in the designated place, and can not be littered everywhere.

Three, precautions during maintenance

时 When performing maintenance on the IF electric furnace, keep the IF generator room clean. It is strictly prohibited to stack flammable and explosive items. Repair the over-melted furnace in a timely manner. Avoid mixing iron filings and iron oxide during the furnace repair to ensure the crucible is compact.
