How long does it take for an induction melting furnace to melt a furnace of molten iron?

The induction melting furnace is equipped with different intermediate frequency power supply powers. It can be done for as long as a furnace of molten iron can be melted. Normally, it is between tens of minutes and 90 minutes. The greater the power of the intermediate frequency power supply, the faster the melting speed and the furnace capacity. The larger the melting speed should be slower. It takes 40 minutes for 1T induction melting furnace to melt 1 ton of cast iron at 1550℃ with the power of the intermediate frequency power supply of 1000kw.
