High Power density induction furnace

Brief introduction of MF induction furnace system AC current with 50Hz or 60Hzshall be firstly converted into DC current through three phases bridge type rectifier configured with SCR and then, through the inverter, the AC current with medium frequency (shorted as MF below) to be output. The MF power supply then shall, through copper busbar and water-cooled electrical cable, feeds power to the inductor (induction coil) of the MF furnace for transforming it into alternating magnetic field, which shall make the metal in the crucible producing eddy current for heating and melting. The furnace consists of the furnace body, pedestal, intake system of water and electricity, furnace lid device, hydraulic system, furnace tilting oil cylinders, swing/lifting cylinders for furnace lid (available for FN more than 1.5t), push out device for worn lining (to be equipped according to the users demand) and crucible alarming device, etc.. The solid state power supply (shorted as SPS below) configured with the single integrated circuit Micro-CPU control board, which as the core component for SPS, may detect, display, feedback, follow up control and over-bound protect the electrical parameters such as electric current,power and frequency, etc., also detect and protect the parameters of water cooling such as water temperature and water pressure, etc.
