Vacuum Induction Melting Furnace
The vacuum induction melting furnace utilizes the principle of electromagnetic induction to heat and melt metal raw materials in a vacuum environment. Using an induction coil, it generates an alternating magnetic field, causing eddy currents in the metal itself to heat and melt. This reduces oxidation, removes impurities, and ensures melt purity. Capable of melting stainless steel, high-temperature alloys, and titanium alloys, it is widely used in universities and research institutes.

FAQ
Focus on answering common questions to provide users with clear and practical usage guidelines:
-
Q:How does induction melting's vacuum and refining meet electronics' metal needs?
A:The vacuum environment in induction melting reduces harmful gas emissions to avoid molten metal defects like porosity, and provides sterilization by removing contaminants. With targeted refining to clear inclusions and adjust composition, it meets high-purity metal needs of aviation and electronics.
-
Q:How does the material selection of an induction crucible positively impact melting efficiency?
A:Choosing a crucible material suitable for the metal being melted can reduce reaction losses between the crucible and the molten metal, extending the life of a single use. Furthermore, high-quality crucibles offer thermal conductivity that better matches the characteristics of induction heating, accelerating melting speed and improving production efficiency.
-
Q:How can the cooling water system adapt to the needs of different melting stages?
A:The water flow can be adjusted according to the melting stage: increasing the flow rate to enhance heat dissipation during temperature rise, and appropriately reducing the flow rate during temperature retention. This not only meets the cooling needs of each stage but also avoids energy waste.
