(1) The induction melting furnace should use a dedicated rectifier transformer to increase the supply voltage and limit the no-load operation of the transformer.
(2) Standard installation, shorten the connection between high voltage, transformer, intermediate frequency power supply and electric furnace. Use high purity T2 copper or oxygen-free copper, especially induction coils and water-cooled cables. Increasing its cross-sectional area can effectively reduce the current. Heat loss.
(3) Select a suitable capacity and frequency induction melting furnace according to the casting process, increase the power density to improve the melting efficiency, and reduce additional losses.
(4) It is preferred to choose a steel shell furnace with an intermediate frequency power supply and a series inverter with yoke and hydraulic pressure. The furnace shell connection prevents metal contact from forming a short circuit during operation.
(5) Formulate a reasonable casting process, standardize the technological operations from modeling, material selection, melting, pouring, heat treatment, and cleaning, and scientific management to reduce energy consumption.
(6) Strengthen equipment management and maintenance, reduce failure rate, and ensure smooth production.
(7) Always check whether the connection parts of the conductive systems are in good contact, especially whether the screws at the joints between the water-cooled cable and the induction coil are tightened. The insulation table and boots must be inspected once a year.
(8) It is strictly forbidden to cut off the electricity and water during the smelting process. Pay attention to the water temperature and water pressure at all times during the smelting process to keep the water pressure at 0.1 ~ 0.3MPa and the water temperature below 55 °.
