Abstract

The invention discloses an intermediate frequency induction coil. The intermediate frequency induction coil includes: effective coils, which are multiple groups independently arranged on the periphery of the crucible from top to bottom, and each group of effective coils has a water cable inlet and a water cable outlet; empty coils, which are located in the multiple independent effective coils. The upper and lower parts of the ring have magnetic shielding effect; a plurality of bakelite rollers are located around the effective ring and the empty ring, and are used to fix the effective ring and the empty ring as a whole; and a magnetic shielding plate. The intermediate frequency induction coil has multiple groups of effective coils fixed on the periphery of the crucible, and can be used in conjunction with a set of intermediate frequency power supply intelligent adjustment system, so as to distribute the output current of each group of effective coils according to the height of the molten metal level, and realize intermediate frequency induction heating Intelligent adjustment, optimized power distribution, and maximized efficiency utilization.

Description

technical field [0001] The invention relates to the field of vacuum induction melting furnaces, in particular to an intermediate frequency induction coil. Background technique [0002] Now, the vacuum induction melting furnace is an important metallurgical equipment. It uses the principle of electromagnetic induction to generate eddy current heat as a heat source to heat, degas, melt and refine various metal charges in the crucible to achieve full melting of the charge, accurate composition and distribution. Uniform purpose. [0003] As the charge melts from a solid state to a liquid state, the top of the charge gradually descends, and the heating effect of the upper half of the coil on the charge gradually weakens. At the same time, in order to maintain the full liquid state of the charge, the intermediate frequency power supply continues to output current to the induction coil, especially in the refining stage. It can be lowered to the middle of the crucible. In order to ...
