What are the main advantages of electric furnaces?
Electric furnaces are widely used for the smelting of non-ferrous metals [mainly used in the smelting of ferrous metal materials such as steel, alloy steel, special steel, cast iron, and the smelting of non-ferrous metal materials such as stainless steel and zinc. It can also be used for the smelting and heating of non-ferrous metals such as copper and aluminum. , heat preservation, and can operate in tandem with the blast furnace.
Fast heating speed: The induction heating principle of the electric furnace is electromagnetic induction. The heat is generated by the workpiece itself. Therefore, the heating speed is fast, the oxidation is minimal, the process repeatability is good, the material and cost are saved, and the mold life is extended.
High temperature control accuracy: The application of a temperature control system can achieve precise temperature control, ensure product repeatability, and improve product quality and qualification rate.
Good equipment performance: In recent years, electric furnaces have adopted advanced IGBT variable frequency induction heating devices, which have high component density, excellent performance, better startup, more reliable use, simple and convenient maintenance, less floor space, and more advanced manufacturing processes.
Short smelting time: The furnace body and furnace lining of the electric furnace are made of new structures and new materials. The parts close to the inductor coil are isolated with high-insulation and high-strength materials, which greatly extends the service life of the crucible and furnace and makes it easier to replace the crucible.
Energy saving and environmental protection: Electric furnaces have high heating efficiency. Compared with coal furnaces, workers will no longer be baked and smoked by coal furnaces under the scorching sun, which effectively reduces energy consumption. It has high labor productivity, no pollution, and the equipment is more environmentally friendly. The department’s various indicator requirements.
To sum up, the electric furnace has the advantages of fast heating speed, easy operation, high temperature control accuracy, good equipment performance, short melting time, energy saving and environmental protection in the mold steel manufacturing process.
The role of LF and VD is also very important
Ladle furnace refining and vacuum degassing play an important role and significance in mold steel manufacturing. ladle furnace refining can further remove harmful elements and gases in steel and improve the purity and quality of steel. vacuum degassing can further reduce the oxygen, nitrogen and other gas content in the steel and improve the density and toughness of the steel. these measures can improve the performance and service life of mold steel, so when manufacturing mold steel, the application of out-of-furnace refining and vacuum degassing should be fully considered.
