Induction smelting is a process of melting metal by using electromagnetic induction to generate eddy current heating in metal materials within an induction furnace, also known as induction melting.
Electromagnetic Induction: Induction smelting uses electromagnetic induction to generate eddy currents in metal materials in an induction furnace. This method is suitable for melting high-grade alloy steel, high-grade cast iron, high-temperature alloys, electrical engineering alloys, etc., as well as non-ferrous metals and their alloys such as copper, aluminum, zinc, etc.
Induction Coil: The main parts of the induction furnace include the induction coil, furnace body, power supply, and control system. The induction coil is made of water-cooled copper pipes in a spiral hollow cylindrical shape, with a ratio of inner diameter to height usually between 1:2 and 1:3. The pitch of each turn of the spiral is equal, and sufficient space is left between turns for insulation.
Material Preparation: Place the metal material to be smelted into the furnace.
Induction Heating: High-frequency current generates a magnetic field in the induction coil, which in turn induces eddy currents in the metal material, rapidly heating the metal.
Melting: The metal melts under the effect of induction heating, forming liquid metal.
Smelting Control: Control the smelting process and temperature accurately by adjusting the parameters of the power supply and induction coil.
Cooling and Casting: After smelting, the liquid metal can be cooled and cast to form the required metal castings.
Efficient Heating: Induction smelting can achieve rapid and uniform heating, with high thermal efficiency and fast smelting speed.
Easy Operation: The induction smelting process is highly automated, making it easy to operate and reducing the complexity of manual operations.
Environmentally Friendly: Compared with traditional smelting methods, induction smelting does not produce a large amount of harmful gases and dust, having a smaller impact on the environment.
High Material Utilization Rate: Due to the more uniform melting and mixing of metals during the smelting process, the utilization rate of materials is higher.
Induction smelting is widely used in the casting industry, including the melting, holding, and nodulizing of cast iron, as well as the melting, holding, and alloying of steel castings.
In addition, induction smelting is suitable for the preparation of high-performance metal materials, such as high-entropy alloys. High-entropy alloy matrix composites reinforced with in-situ TiC particles, such as FeCoCrNiCu, can be successfully prepared using vacuum induction smelting methods.
Full air cooled induction heating technology, including the heating coil is also made of special custom materials, without additional water cooling.
With intelligent control system, constant power output mode, including full power output and constant power output, the temperature of zinc liquid can be controlled within 3 degrees to achieve the purpose of improving the quality of zinc liquid.
Heating rod heating, that is, direct heat conduction of zinc liquid heating, effectively improve the efficiency of heating zinc liquid. Further reduce the atmosphere temperature in the furnace, reduce the zinc oxide slag formed by the combination of zinc liquid and air, and can achieve continuous use of 1 month to 3 months without slag cleaning.
Energy saving effect, achieve electromagnetic induction heating rod heating, heat conduction to zinc liquid, compared with the traditional silicon carbon rod heating with the air to the zinc liquid slow heat conduction characteristics, energy saving of about 30%.
