Medium frequency electric furnce coil is the heart of the induction furnace, induction coils in the role of the current produced under strong magnetic field, the magnetic field in the furnace of metal produce eddy current and fever. Coil heat energy is electrical energy conversion to the key, so the coil design is very important. The yiphee furnace with intermediate frequency electric stove coil is the actual use of the situation, according to the principle of electromagnetic field, through the calculation of computer professional software and set a better plan, the design of the induction coils of power and the power of the actual operation error is not more than 5%, the insulation of the coil, especially between the use of advanced turns insulation insulation treatment ways to ensure, special clamping technology can effectively reduce the coil axial vibration. Induction coil with imported high temperature resistant wall insulation materials, and equipped with leak furnace alarm system, which can effectively prevent medium frequency electric furnace wear furnace. Optional lining ejector institution, can quickly remove damaged lining, convenient and rapid furnace building.
