Introduction of melting process of intermediate frequency furnace melting furnace-Kehua
With the rapid development of society and economy, the intermediate frequency furnace melting furnace has become more and more important for the smelting industry. Do you know the introduction of the smelting process of the intermediate frequency furnace melting furnace? Kehua will introduce the intermediate frequency furnace melting furnace in detail for you, come and have a look. Intermediate Frequency Furnace Melting Furnace Intermediate frequency furnace is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency (above 300HZ to 1000HZ), converts three-phase power frequency alternating current into direct current after rectification, and then converts direct current into adjustable intermediate frequency current , supply the intermediate frequency alternating current flowing through the capacitor and the induction coil, generate high-density magnetic lines of force in the induction coil, and cut the metal material contained in the induction coil, generating a large eddy current in the metal material. Smelting furnace Smelting furnace refers to the equipment that melts metal ingots and some scrap metals and adds necessary alloy components, and smelts them into the required alloys through slag removal, refining and other operations. Intermediate frequency furnace smelting process Due to the low temperature of the slag of the induction furnace and the weak chemical ability, the non-oxidizing method is mostly used to make steel. Under normal circumstances, after the charge is completely melted, deoxidation, chemical composition adjustment and tapping are carried out. Due to the weak chemical reaction ability of slag, dephosphorization and desulfurization are generally not carried out in the steelmaking process. Both acidic and basic furnace linings are used in production. Smelting process 1. Furnace building The refractory material used in the lining of the acid induction furnace is silica sand. The binders are generally boric acid and water glass. The refractory material of the alkaline induction furnace is magnesia, and the binder is boric acid and water glass. Intermediate frequency furnace smelting furnace 2. Charge and charging The acid induction furnace cannot be dephosphorized and desulfurized, so the charge used must be low in phosphorus and sulfur. The alkaline induction furnace can dephosphor Induction furnace steelmaking generally does not use oxidation. Since there is no means of oxidative decarburization and boiling refining, the source of gas and inclusions should be reduced (the charge should be free of rust and oil on the surface), and the chemical composition of the charge should be clear and precise ingredients are required, and the charge should not be too large or too small. , the principle is to make the charge compact to facilitate magnetic and electrical conductivity. The above is the detailed introduction of the intermediate frequency furnace melting furnace. Did you know about the intermediate frequency furnace melting furnace after reading it?
