What are the measures to improve the operating environment of induction melting furnaces?

Measures to improve the operating environment of the induction melting furnace equipment include: eliminate smoke and dust; reduce noise; reduce environmental temperature; eliminate pollution to the power grid.

The main noise of the เตาหลอมเหนี่ยวนำ comes from the oscillation of the magnetic yoke and coil, in addition to noise sources such as fans and water pumps. Under normal circumstances, the noise is not significant, and no major measures need to be taken. However, with the advent of large-capacity intermediate frequency power supplies, the power density of induction melting furnaces has increased from 250-300kW/t for induction melting furnaces in the past to 500-600kW/t or even as high as 1000kW/t in this case. Take necessary measures for the yoke part of the induction melting furnace body and the clamping member of the induction coil to reduce its noise. The induction melting furnace is a continuous long-term operation method. According to the relevant standards of our country, the noise should be controlled below 85dB.

The main measure to reduce the ambient temperature is to reduce the time of opening the lid. For large furnaces, a small furnace cover with a small diameter is usually opened on the furnace cover for observation, sampling or adding a small amount of alloy, which can effectively reduce the radiant heat to the surrounding environment when the cover is opened.

The elimination of smoke and dust, the ventilation of the electrical room, and the elimination of the high-order harmonics generated by the intermediate frequency power supply of the induction melting furnace are three measures that need to be paid attention to.
