Induction Furnaces

Refractory Casing for Induction Furnace Refractory casing, as known as high temperature-resistant casing, or silicone rubber fiberglass casing, is made of high-purity alkali-free glass fiber, and then coated with organic silica gel on the outer wall of the pipe and vulcanized. After vulcanization, it can be used for a long time in the temperature range of -65°C - 260°C and maintain its soft and elastic properties. The refractory casing can be used in high-temperature workshops. Many pipes, valves, or equipment have very high internal temperatures. If they are not covered with protective materials, it is easy to cause burns or heat loss. The refractory sleeve has better thermal stability, radiation resistance, and heat insulation than other polymer materials, preventing accidents and reducing energy consumption. If the temperature is too high, save the cooling cost. Moisture-proof, oil-proof, weather-proof, and anti-pollution, prolong the service life of the equipment. The cables and hy...

Electric arc VS Induction Furnace The Difference Between  Electric Arc Furnace VS Induction Furnace The Cost Difference Between Electric Arc Furnace VS Induction Furnace Compared with the electric arc furnace, the steelmaking cost of the induction furnace is lower, and it is suitable for small and medium-sized enterprises (small workshops) However, the steel he smelt has many impurities and high carbon content, so the steel smelted is not pure. If the requirements are not high, you can choose induction furnace steelmaking. The volume of the electric arc furnace is generally more than 3 tons, so only enterprises with a certain scale can use the electric arc furnace, and the steel produced by it is relatively pure. The difference in Electricity Consumption Between Electric Arc Furnace VS Induction Furnace The Same Points:                               1. Both use electricity;       ...

How Does an Electric Induction Furnace Work? The electric induction furnace is a power supply device that converts the power frequency of 50HZ alternating current into an intermediate frequency (above 300HZ to 1000HZ). It converts three-phase power frequency alternating current into direct current after rectification and then converts direct current into adjustable intermediate frequency current, which is supplied by capacitors. And the medium-frequency alternating current flowing in the induction coil generates high-density magnetic force lines in the induction coil, and cuts the metal material contained in the induction coil, generating a large eddy current in the metal material. The working frequency of an electric induction furnace  (hereinafter referred to as an intermediate frequency furnace) is between 50 and 10 Hz, and it is widely used in the smelting of non-ferrous metals and ferrous metals. Compared with other casting equipment, the medium-frequency induction furna...

Composition of medium frequency induction furnace The intermediate frequency induction furnace system is composed of the transformer of the power supply part, the intermediate frequency power cabinet of the intermediate frequency power supply part, the induction coil of the furnace body part, the closed cooling tower of the cooling part, the auxiliary transmission part, ...

Electric Induction Furnace Diagram Induction furnace steelmaking is a steelmaking method that uses induction electrothermal effect to heat and melts metal. It is especially suitable for smelting a small amount of high-quality steel and alloy with high-quality raw materials (high-quality scrap steel, ferroalloy, etc.). The vacuum induction furnace equipped with a vacuum system is an important piece of equipment for smelting high-quality alloys. Induction furnaces are widely used in metal smelting and are the main equipment in foundry and heat treatment workshops. The intermediate frequency induction furnace converts the three-phase power frequency alternating current into direct current after rectification, and then converts the direct current into an adjustable intermediate frequency (above 300hz to 20khz) power supply, and flows through the intermediate frequency alternating current in the capacitor and induction coil to generate high density. The magnetic line of force cuts the meta...

Electric Induction Furnace Steel Electric Furnace Steel Electric furnace steel is steel produced in a steelmaking furnace powered by electricity. There are many types of electric furnaces, including electric arc furnaces, induction electric furnaces , electro-slag furnaces, electron beam furnaces, and consumable electric arc furnaces. But the so-called electric furnace steel is the steel produced by a basic electric arc furnace. There are various types of electric furnace steel, mostly high-quality carbon structural steel, tool steel, and alloy steel. The electric furnace steel has excellent quality and uniform properties. When the carbon content is the same, the strength and plasticity are better than open hearth steel. Electric furnace steelmaking has the advantages of less pollution, high thermal efficiency, and high smelting quality. But it also has the disadvantages of large power consumption and high production cost. Electric furnace steel production is one of the main production...
