Intermediate frequency furnace via power management techniques to eliminate harmonic disturbance caused by the medium frequency furnace? A: obviously interference problem. May be harmonic, may also be conducted radiation interference, is likely to be this kind of electromagnetic interference problem. Harmonic can use harmonic filter, conduction radiated interference power supply filter can be used. Schaffner emc is a professional do the power quality of this piece, intermediate frequency furnace is obviously a nonlinear load, the harmonic problem is possible. Intermediate frequency furnace causes of harmonic, and how to governance. A: intermediate frequency electric furnace is due to the power frequency inverter for medium frequency power supply by the rectifier, in the process of the work for grid produced a large number of damaging the higher harmonic, is one of the largest harmonic source in power grid load. Harmonic will seriously affect the safe operation of power grid, such as harmonic current in the transformer, high frequency eddy current to generate additional iron loss, make the transformer overheating, reduces the output of the transformer capacity. What is the difference between the electric arc furnace and intermediate frequency furnace answer: 1, the electric arc furnace, big volume are generally not more than 3 tons, have a certain scale of the enterprise to use the electric arc furnace, smelting steel is more pure. Intermediate frequency furnace: relative electric arc furnace steelmaking cost lower, suitable for small and medium enterprises, refining the steel material, high carbon steel coming out is not so pure. 2, electric arc furnace with electric power frequency; Intermediate frequency electric furnace used. I want to ask, frequency converter, intermediate frequency furnace can achieve the goal of energy saving, intermediate frequency furnace power management answer: in theory, frequency converter can be control of intermediate frequency furnace, to be honest, seen not thousands of intermediate frequency furnace, several hundred affirmation is some, but have never been used. Reason may be that there are two aspects: first, the frequency converter control cost is very high, may the inverter cost than the cost of intermediate frequency furnace, if the two together, with. Intermediate frequency furnace and induction cooker heating principle? Intermediate frequency furnace power management answer: 1, intermediate frequency furnace is mainly composed of induction coil, induction coil, power supply, and made of refractory material in the crucible. Within the crucible containing metal furnace charge, equal to each winding transformer, induction coil, when on ac power, to produce alternating magnetic field in the induction coil, the magnetic force line in the crucible furnace charge, metal is produced in the furnace charge induction electromotive force, formed due to charge itself. Ferroalloy enterprises of intermediate frequency furnace ( KGPS - 1250 - 500). General electric energy conversion answer: general efficiency at about 85%, not too high, it is not realistic. Intermediate frequency furnace pollution in the intermediate frequency furnace power management a: soil, that is the metal smelting, as well as dust, you add dust removal system, pollution is small, medium frequency furnace in the smelting industry is more environmental protection equipment, hope can help you. The service life of intermediate frequency furnace answer: in addition to the requirements of the physical and chemical indicators, burden coefficient of expansion as small as possible, in order to avoid the use of expansion of crack due to repeated temperature difference effect, affecting the service life of crucible. According to the equipment models, melting materials of ph and melting temperature control to determine. At present, the domestic intermediate frequency furnace crucible of masonry materials with quartz sand and high alumina materials. Suitable for the high alumina material 500 kg. Intermediate frequency furnace installation requirements answer: user, please first provide the scene graph and the scene of some of the requirements or the technical parameters, designed by experts detailed on-site installation plan; Equipment for basic requirements: the flat cement ground, without a fixed or slightly fixed; Equipment should be placed on ventilation, shade, outdoor shade; User is responsible for the installation of materials and the need of civil engineering and the necessary tools, I. Answer: according to the characteristics of the main harmonic frequency produced by intermediate frequency furnace is measured, and then according to the results of the measurement to determine the direction of the harmonic governance, for example, may be one, or a certain characteristic frequency harmonic, 5,7,11,13 inferior, and then on the basis of the characteristic frequency to formulate special filter circuits, prompting the whole standard of intermediate frequency furnace harmonic. Also. Intermediate frequency furnace power management technical information how to select frequency furnace lc intermediate frequency furnace power management a: intermediate frequency furnace in use to produce a large number of harmonic, harmonic pollution in the power grid is very serious. Harmonic make and use in power transmission efficiency is lower, the electrical equipment overheating, vibration and noise, and make its insulation ageing, reduce the service life, even down or burned; Harmonic can cause local parallel resonance or serial resonance power system, the harmonic content. Intermediate frequency furnace service life of the intermediate frequency furnace power management a: in addition to the requirements of the physical and chemical indicators, burden coefficient of expansion as small as possible, in order to avoid the use of expansion of crack due to repeated temperature difference effect, affecting the service life of crucible. According to the equipment models, melting materials of ph and melting temperature control to determine. At present, the domestic intermediate frequency furnace crucible of masonry materials with quartz sand and high alumina materials. Suitable for the high alumina material 500 kg.
induction melting furnace steel shell furnace, as the name suggests, find extensive use in steel melting induction furnace institutions. Since induction electric melting furnace has become much dependent on technology in today's world, there is wide use of such induction heating furnace.
