The new intermediate frequency furnace technology, an intermediate frequency furnace can't normal answer: start the new intermediate frequency furnace below is I have years of experience, intermediate frequency furnace fault and solutions; 1 boot cannot start, first check the power supply three phase is normal, lack of phase is not starting. Carefully check the control circuit is loose, it is best to tighten the screws. Motherboard power supply is normal, general motherboard is 15 v, common three-terminal voltage regulator to 7815 voltage regulator, to focus on. Often in the vicinity of intermediate frequency furnace work what's the harm? ? ? A: the new intermediate frequency furnace is a kind of intermediate frequency furnace will power frequency 50 hz alternating current into intermediate frequency ( More than 300 hz - 10000 hz) Induction coil, power supply units, deserve to go up and compensation capacitor, applied the principle of electromagnetic induction heating equipment. Widely used in non-ferrous metal and black metal and melting, heating. Such as melting cast iron, ordinary steel, stainless steel, tool steel, copper, aluminum, gold, silver and alloy, etc. ; Through. Intermediate frequency furnace equipment characteristics of the new intermediate frequency furnace answer: low heating speed, high production efficiency, less oxidation decarburization, save material and cost, extend the service life of mould due to the principle of electromagnetic induction medium frequency induction heating, the heat inside the workpiece itself, ordinary workers with intermediate frequency electric furnace to work after ten minutes for the task of forging work continuously, without burning furnace professional workers for burning furnace and furnace work ahead of time. Due to the. Intermediate frequency furnace service life of the new 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. Failure 1 failure phenomenon: intermediate frequency furnace large dc current when starting, low voltage dc voltage and frequency and over-current protection device and start the deep voice. Analysis: there is a bridge inverter bridge arm of the thyristor may cause short circuit or open circuit inverter bridge running three arm bridge. Oscilloscope were observed four bridge inverter bridge thyristor (tube voltage waveform on the arm of the if there is a bridge. Intermediate frequency furnace maintenance common sense A: silicon controlled rectifier is good or bad judgment A measurement gate ( 门将) Resistance, the resistance in 8 - commonly - - Measurement of Yin and Yang (50 b AK) Resistance measurement should be open, measurement in K - in the road - - Note: in the multimeter is positive and negative way or open in the medium frequency power supply circuit, the test method can only be simple judge of silicon controlled because of the size and usage of SCR is different, the test. Intermediate frequency furnace energy-saving reform of the new intermediate frequency furnace answer: such as panel optimization, furnace optimization, the other is a divine the latest IGBT medium frequency furnace, electric furnace production energy saving rate is much higher than the original KGPS medium frequency furnace, http://wwwnb- shenguangcom /cn/productsphp。 Intermediate frequency furnace used for a period of time will not be able to start a: startup, the furnace of iron is hot or cold iron? Can't start, how many furnace of iron. What are the common faults intermediate frequency furnace? Answer: 1, the startup system without any reaction (1) rectifier board failure; (2) over current, over voltage protection action; (3) the main switch is not together; (4) control tuning work potentiometer damage or break; (5) rectifier control power supply part of the bad. 2, only dc voltmeter has instructions, other no reaction (1) inverter board and inverter circuit fault; (2) the inverter power supply failure. No 22 v inverter pulse power supply. Note:. The maintenance of the common sense answer: medium frequency furnace oven for dry type furnace, furnace of steel is not out. When the oven must be based on the principle of add sauce and infill, avoiding local flint and melt the tank, make the dry material to collapse. So try to save a few small in front of the oven. At the same time in the process of heating up to strictly observe the steel case, when a dozen arc serious should reduce current, if the current in the lead. New intermediate frequency furnace medium frequency furnace manufacturers technical data a: what are the new intermediate frequency furnace Shanghai new research industrial equipment co. , LTD. , Shanghai new research industrial equipment co. , LTD is invested by HaiDing on letter ( Group) Co. , LTD, invested and controlled by a collection of r &d, production, sales in the integration of medium frequency induction furnace and the induction heating equipment manufacturing enterprises. Address: 1015 new rivers sand road baoshan district of Shanghai. What are the advantages of IGBT medium frequency furnace answer: saving features low heating speed, high production efficiency, less oxidation decarburization, save material and cost of forging die due to the principle of electromagnetic induction medium frequency induction heating, the heat inside the workpiece itself, ordinary workers with intermediate frequency electric furnace to work after ten minutes for the task of forging work continuously, without burning furnace professional workers for burning furnace and furnace work ahead of time. Don't have to bear. How to play the new intermediate frequency furnace furnace for good new intermediate frequency furnace answer: it depends on you what kind of burden, quartz sand? Or a neutral charge, the craft is different, generally charge suppliers will have to play the furnace process, I just do the intermediate frequency furnace lining, can free service for you. Intermediate frequency furnace reactive compensation answer: god light electric data ( Please visit shekinah furnace query more) : in the face of the domestic large number of intermediate frequency furnace and the urgent need of environmental protection and energy saving a lot of manufacturers and try to do a lot of useful efforts. Some manufacturer use system transient protection class, surge, higher harmonic suppression products of intermediate frequency furnace system, practice shows that the intermediate frequency furnace harmonic content more than 85% for low harmonics. What are the common faults intermediate frequency furnace? A new intermediate frequency furnace: 1, the startup system without any reaction (1) rectifier board failure; (2) over current, over voltage protection action; (3) the main switch is not together; (4) control tuning work potentiometer damage or break; (5) rectifier control power supply part of the bad.
