Can a natural gas furnace replace the melting furnace ?

It depends on the hardness and power of the parts you process. The melting furnace is suitable for induction heating and smelting of various metal materials with high power. I don't know what you are doing, depending on the advantages of your materials. The furnace, the intermediate frequency electric furnace is a power supply device that converts the power frequency 50HZ alternating current into the intermediate frequency ( 300HZ to 1000HZ ), converts the three-phase power frequency alternating current into a direct current, and then converts the direct current into an adjustable intermediate frequency current. The intermediate frequency alternating current flowing through the capacitor and the inductive coil is supplied, and a high-density magnetic line is generated in the induction coil, and the metal material contained in the induction coil is cut to generate a large eddy current in the metal material.
