Article about Induction Furnace INDUCTION FURNACE The environment FRIENDLY MELTING EQUIPMENT Today preserving the Environment is supporting joints such as duty most word citizens. Nature has supported all human development activities over the year. However man's greed read more and more has tilted the good balance to such an extent that survival of making on the modern world has. Turn into a big question mark. Extraction of metals from primary sources (ores) is a very energy intensive activity hence recycling of metals has gained importance considering previously mentioned fact. Even here regarding Coal and other hydrocarbons cause energy sources cause immense environmental pollution and it is in this context. What an Induction Air conditioner? A water cooled Copper coil carrying High Frequency Current, produces eddy current in the charge / metal within the coil. Numerous hearts the shared metal and melts it. Handy working on such a principle is known as an INDUCTION FURNACE. The primary ingredients of an Induction Furnace: Medium frequency furnaces operate at frequencies ranging form 150 to 10,000 Hertz. Such furnaces prove concentrated High Power in small volumes with a definitely higher melt rate. Today the Coreless Medium Frequency Induction Furnace is extensively used than its Channel type comparable version. In an Induction Furnace, Electrical Energy is reconstructed as Magnetic Energy and again back to Electrical Energy which is converted into Heat the particular Joule Effect Crucible: Structurally it consists of three independent but interdependent sections: 1.Base Frame 2.Tilting Frame 3.Interchangeable Inductor comprising a coal created from specially shaped copper section featuring high strength as well as high conductivity. The melting basin positioned inside the inductor (coil) is isolated by a thick refractory lining the. A special hydraulic system ensures easy emptying, smooth and complete pouring. That the Induction Furnace assumes importance for its eco friendliness and energy efficiency. ADVANTAGE Of your INDUCTION FURNACE Faster Startup Flexibility Natural stirring Clean melting Simple Operation Higher Yield Low refractory cost Better working environment A Typical installation includes 1.Crucible 2.Solid state power converter 3.Power factor compensation capacitor bank 4.Auxiliary equipments Solid State Power Converter: Converts the series / mains frequency to some medium frequency essential for efficient undertaking. 1.Conversion from AC to DC 2.Rectifying & filtering DC current 3.Converting DC into AC (Medium Frequency) 4.Electrical safety, Protection, Regulation and Control circuits Closed loop water to water heat exchange using De mineralized pond.
