The coil is the heart of the induction melting furnace. The induction coil exerts a strong magnetic field under the effect of the current, which causes the metal in the furnace to vortex and heat up. The coil is the key to the conversion of electrical energy into heat, so the depiction of the coil is very important. The coil of the furnace is in contact with the induction use of the induction melting furnace. According to the principle of electromagnetic field, the better plan determined by the accounting software of the computer, the latest coil anti-winding skill (double induction loop parallel), very good collection The magnetic field, the magnetic field mixing force, the induction coil's drawing power and the actual running power error are not more than 5%. The insulation of the coil, especially the inter-turn insulation, uses the leading insulation treatment method to ensure that the special clamping skill can be effectively reduced. The axial oscillation of the coil.
