Induction Furnace Assembly Copper Coil
Induction furnace assembly copper coil, also known as inductor, is made by winding extruded rectangular copper tubes with a grade of T2 (purity of 99.9% electrolytic copper) and a wall thickness of ≥ 6 on a dedicated mold. It not only ensures the rigidity of the coil, but also has the largest conductive cross-section. The coil is the heart of an induction furnace. Under the action of current, the induction coil generates a strong magnetic field, which causes eddy currents in the metal inside the furnace and generates heat. The coil is the key to converting electrical energy into thermal energy, so the design of the coil is very important.
The appropriate number of turns in the coil can achieve maximum electrical efficiency. The copper tube of the induction coil is made of high conductivity TU1 oxygen free copper tube, and the coil is supplied with cooling water by multiple waterways. The induction coil is evenly distributed and coated with high temperature and high voltage resistant insulation paint, which is immersed and vacuum dried as a whole, achieving an insulation level of H. Before leaving the factory, the induction coil will undergo a 12kg/cm2 test (as shown in the attached picture of the connection between the water pipe and the induction coil), and there will be absolutely no water leakage.
The upper and lower parts of the induction furnace assembly copper coil are not only equipped with water-cooled coils to ensure uniform heating of the furnace lining. And it is equipped with Faraday short-circuit rings to fully absorb the leakage magnetic flux at the upper and lower ends, preventing the furnace from heating up. The sensor is powered by a large section water-cooled cable and adopts a side lead out form. The coil clamping device adopts a stainless steel rod to tighten up and down, which is easy to disassemble and replace the coil..
