Taizhou stop using the principle of intermediate frequency furnace
technology, an intermediate frequency furnace answer: medium frequency induction furnace
works: PS series power supply adopt ac -
Ac frequency conversion way, by a (
Three-phase bridge rectifier three-phase alternating current into direct current, and then by a single-phase bridge inverter dc into intermediate frequency alternating current (ac), and intermediate frequency ac induction coil, when passing a medium frequency induction coil produces alternating alternating current (ac).
Intermediate frequency furnace copper laps leaking blow-in influential? Answer: medium frequency furnace copper laps leaking furnace.
Can try the following treatment method: medium frequency furnace in use process, can appear sometimes furnace inductor turn-to-turn flint and leaking, stay after the traditional processing method is tilting furnace crucible cooled, remove oxygen sensor with welding repair again after installation construction.
Greatly reduces the average electric furnace crucible furnace life.
After practicing, is summarized.
Intermediate frequency furnace maintenance common sense A: silicon controlled rectifier is good or bad judgment A measurement gate (
Resistance, the resistance in 8 - commonly
Measurement of Yin and Yang (50 b
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.
1 acid lining material: carbon steel smelting.
Quartz sand (
40%, quartz sand,
5 ~ 2% (
2%, water (
Quartz sand should be magnetic separation, remove the ferromagnetic material.
Alkaline lining: for alloy steel smelting.
A 4 x 4 mm sieve)
96%, refractory clay,
Intermediate frequency furnace which is the best answer: medium frequency furnace problem can look for 'divine radiation electric furnace,' baidu professional is minority after all, you go to search their company's web site or directly to make a phone call best consulting market research in the past, the hope can help you.
The working principle of intermediate frequency furnace a. INDUCTOTHERM induction melting system evolution of INDUCTOTHERM induction melting system the basic structure of the rectifier part of furnace body parts of an alternating current through the rectifier inverter into direct current, dc energy is stored direct current through the required frequency inverter into the alternating current supply of furnace body part INDUCTOTHERM parallel inverter ac current feedback.
Principle of intermediate frequency furnace figure a. INDUCTOTHERM induction melting system evolution of INDUCTOTHERM induction melting system the basic structure of the rectifier part of furnace body parts of an alternating current through the rectifier inverter into direct current, dc energy is stored direct current through the required frequency inverter into the alternating current supply of furnace body part INDUCTOTHERM parallel inverter ac current feedback.
Wear in medium frequency furnace before what are the symptoms of a: 1 observe furnace wall thickness distribution, will understand probably punched parts.
2 after each furnace hot metal pouring, observe whether the lining is the part of the black mark.
3 in the part of the black mark, supplement the reoccupy after with sand.
4 for the sake of safety, not sure to stop using it.
Intermediate frequency furnace control board rectifier pulse what is normal phenomenon?
A: after the rectifier dc voltage can rise to the largest input ac 135 times, such as to rise to normal, also is to use an oscilloscope to watch, you ask, is that the voltage is the most intuitive.
Why old medium frequency furnace to burn the same answer: silicon controlled rectifier in the waterways are clear, radiators and thyristor (
Silicon controlled rectifier)
The installation of the standard under the premise of damage of the old one and the same position of the thyristor, you have to check: with the thyristor corresponding resistance capacity to absorb circuit is open,
Resistance or capacitance internal circuit)
Check the corresponding to the pulse of the thyristor power amplifier boards, the above resistance, capacitance and diode, including pulse.
Taizhou stop using the intermediate frequency furnace technical information how to improve the medium frequency furnace hot metal flow taizhou stop using the intermediate frequency furnace answer: you this is the right formula may be material, result in hot metal fluidity is very poor, specific you can go to the 'divine radiation electric furnace technology information website see if there is any related articles, maybe can help you.
The difference between cast iron and cast steel medium frequency furnace maintenance a: raw iron hard and brittle, lack of toughness, carbon content 211%
667% more iron carbon alloy and nonferrous impurities.
Cast iron is more than 21% of the iron carbon carbon alloy, it is to cast iron (
Part of pig iron for steel making)
To melt in the furnace, and adding ferroalloys, scrap steel, foundry return the components to adjust.
With cast iron cast iron is the difference between secondary processing, processing into a mostly.
How the online measurement of intermediate frequency electric furnace thyristor is good or bad?
Everyone help answer: online should pay attention to safety, not to teach you the method of electricity, stop the heating time, high temperatures for short circuit, high heating temperature for a period of time the bottom open, novice had better not charged detection.
electric melting furnace aluminum steel melting induction furnace manufacturers, as the name suggests, find extensive use in coreless type induction furnace institutions. Since cast iron melting furnace has become much dependent on technology in today's world, there is wide use of such electric metal melting furnace.
