Induction Furnaces

10-500Kg Vacuum Induction Furnace Specifications The melting of metals by electromagnetic induction heating in a vacuum state is called vacuum induction melting. The main structure of the vacuum induction furnace includes a furnace body, a crucible, an induction coil, a vacuum system, a melting power supply, and a control system. The melting power supply is an intermediate frequency AC power supply, and the frequency selection depends on the metal properties and melting volume. 10-500Kg vacuum induction melting can realize refining, and impurities are removed, decomposed, floated, and volatilized through chemical reactions in the melting process. When the metal is melted to the desired pure state, it is usually poured into the mold through a preheated funnel. Vacuum induction melting is generally used to produce superalloys, stainless steels, composite magnet alloys, and other important advanced alloys. 1. 10-500Kg Vacuum Induction Melting Furnace Application: It is used for smelting a...

Induction Furnace Slag Composition Induction Furnace Slags are often chemically complex and contain a variety of contaminants from raw metals. Slag can make up about 25% of a foundry's solid waste stream. Common slag components include metal oxides, molten refractories, sand, and coke ash (if coke is used), among others. The main metal oxides present in the slag were Fe 2 O 3 (14.30%), Al 2 O 3 (7.89%), MnO (5.06) and CaO (1.49%), and metalloid SiO 2 (66.42). The actual composition of slag is much more complicated. Because of the erosive effect of the slag on the crucible material during the smelting process, a part of the crucible material dissolves into the slag. In addition, the deoxidation reaction products of many deoxidizers are also absorbed by the slag, which complicates the actual slag composition. However, the basic composition of the slag did not change much. What is the function of smelting slag in intermediate frequency induction furnace ? (1) Protect molten steel to ...

Induction Furnace Slag During induction furnace smelting, the metal is heated by induction and then conducted to the slag, so the temperature of the slag is low, and the furnace structure determines that the steel-slag interface is small, which is not conducive to the physical and chemical reactions between the molten pool and the slag. Therefore, when smelting special steel or nickel-based alloys, we should strive to use better raw materials, mix ingredients according to the burning loss of each element, and heat and melt quickly. When a large amount of charge has been melted, slag should be added to reduce oxidation. The slag should be compatible with the furnace lining . After complete melting, according to the composition of the finished product, add deoxidizers (ferrosilicon powder, silicon calcium powder, aluminum powder, etc.) in batches, take samples for analysis, and adjust the composition if necessary. When the composition is qualified and the deoxidation is good, the steel c...

Induction Furnace Refractory Lining Materials Refractory Materials for Induction Furnace Should Meet the Conditions Requirements that Refractory Materials Should Meet Furnace lining refractory materials , no matter whether they are used for heart induction furnaces or centerless induction furnaces, should meet the following requirements. (1) have the good chemical stability Metal aluminum and aluminum alloys not only have high chemical activity but also have excellent fluidity of the melt. The viscosity of molten aluminum at 750°C is only 1.04 centipoise, which is quite close to the viscosity of water at 20°C (1.0 centipoise), which is the main reason why it easily penetrates into the furnace lining and undergoes chemical reactions. At the temperature where the liquid aluminum is in contact with the refractory material, aluminum acts as a strong reducing agent. SiO2, TiO2, FeO, and other oxides in refractory materials should be reduced by aluminum. The reaction between the molten alumi...

Induction Furnace Repair Services Energy-saving intermediate frequency furnace - matters needing attention in maintenance In induction furnace repair services, the energy-saving intermediate frequency furnace needs attention not only before the furnace is turned on, after the furnace is turned on, but also during maintenance. The intermediate frequency induction furnace should check the electrical equipment, cooling water system, induction switch air conditioning copper pipe, etc. before starting the furnace.
