What are the benefits of an induction furnace for an intermediate frequency furnace? What are the characteristics? -Kehua
In many industries, induction furnaces are heavy machines that can be used in many ways. So what are the advantages of the induction electric furnace of the intermediate frequency furnace? What are the characteristics? Kehua will introduce the induction electric furnace of the intermediate frequency furnace in detail. Come and see it together. Intermediate frequency furnace induction 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. The working frequency of the intermediate frequency induction furnace (hereinafter referred to as the intermediate frequency furnace) is between 50 and 10 Hz, and it is widely used in the smelting of non-ferrous and ferrous metals. The advantages of induction furnace of intermediate frequency furnace 1. The atmosphere in the furnace can be controlled The working gas in the furnace can be argon. The gas can maintain a neutral atmosphere in the furnace, and it can be argon, hydrogen or pure hydrogen as the working gas. Keep the reducing atmosphere in the intermediate frequency electric furnace. Nitrogen gas or compressed air can also be used to smelt nitrogen-containing steels or remove them. Different process purposes can be achieved by changing the working gas. Currently, argon gas is mostly used. 2. It can be smelted with or without slag. Under the condition of slag, a series of physical and chemical reactions can be realized, such as deoxidation, desulfurization, decarbonization, etc. The role of slag in the smelting process of intermediate frequency electric furnace is much greater than that of ordinary induction furnace. If only molten steel is poured into castings, slag-free melting can be used. 3. The recovery rate of alloying elements is high. The induction furnace is carried out in a neutral protective atmosphere during melting, refining and pouring. The partial pressure of oxygen in the furnace is very low. If strong reducing slag is used, the burning loss rate of alloying elements will be reduced. very low. Medium Frequency Induction Furnace The outstanding features of the medium frequency electric furnace: In the early stage of the smelting industry, electric arc furnaces were also used a lot. This kind of equipment is a short-circuit large current generated by electrodes short-circuiting each other through carbon rods, and then high temperature is generated to melt molten iron or molten steel. The disadvantage of this kind of equipment is that when it generates high temperature, it will generate dazzling arc light, stab the operator's eyes, and at the same time generate harmful powder gas, which will pollute the environment. It is also burned, which reduces the effective yield of molten steel and elements, increases the cost, and burns the furnace wall. In particular, the lining life of small-tonnage electric furnaces is very low. The relevant departments of the State Economic and Trade Commission have clearly stipulated that electric arc furnaces under 10 tons cannot be used. Therefore, these users have replaced electric arc furnaces with intermediate frequency electric furnaces to improve enterprise efficiency. The above is a detailed introduction to the induction furnace of the intermediate frequency furnace. Do you have any questions after reading it?
