Taizhou does it stop all intermediate frequency furnace technology, an intermediate frequency electric furnace frequency locking is not what's the reason?
Taizhou all intermediate frequency furnace stop? Answer: questions you should ask more clearly: 1 intermediate frequency furnace works well, only the frequency fluctuating model;
2 frequency table kept swinging up and down,
, intermediate frequency furnace can't normal boot.
Belong to the former, check the instrument related wiring and terminals.
The latter case is to check whether there is problem intermediate frequency power source or load.
Stop when the intermediate frequency furnace, how can have instantaneous large current answer: ever show flow, over-voltage, generally is inverter hairy bo reason 1 】
Silicon controlled quality problems.
Seemingly current maximum outage, when the actual current is biggest, the dc voltage is also the biggest, intermediate frequency voltage is also the biggest.
Also have to consider the original compressive Emmanuel.
Intermediate frequency electric furnace operation procedures a: intermediate frequency electric furnace operation procedures: 1, check whether the water drainage systems, the hydraulic pressure gauge is normal, the pipe is leaking.
Electric control cabinet of the feed water pressure for 01 mpa, condenser water pressure 008 mpa, furnace feed water pressure for 02 mpa, transformer of the feed water pressure as 01 mpa.
2, water after normal through to protect the tank control power supply first, in the start of transformer.
Intermediate frequency furnace control board rectifier pulse what is normal phenomenon?
Taizhou all intermediate frequency furnace stop? Answer: 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.
In 2017 after the closure of intermediate frequency furnace scrap down price? A: intermediate frequency furnace generally just melting scrap, don't adjust the carbon content!
If you want to adjust the carbon content, oxygen blowing off carbon oxide, it don't have this ability, also have no test ability.
What is the intermediate frequency furnace?
What are doing?
Taizhou all intermediate frequency furnace stop? Answer: medium frequency furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency (
More than 300 hz - 1000 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 melting, heating.
Such as molten pig iron practice, ordinary steel, stainless steel, tool steel, copper, aluminum, gold, silver and alloy, etc. ;
Diathermy forging purposes.
Intermediate frequency furnace energy-saving?
Answer: medium frequency furnace is a nonlinear inverter, such equipment will work process will produce large amounts of electromagnetic harmonic, the harmonic not only can interfere with other sensitive electrical and mechanical equipment, even lead to electric power metering system disorder, even lead to electric power metering system disorder, at the same time, also can reduce the power factor, or is that the reactive power will increase.
Why opened after intermediate frequency furnace, induction cooker can't heat?
Opened after a: intermediate frequency furnace, induction cooker can't heat, generally because the intermediate frequency interferes with the intermediate frequency furnace control system of induction cooker, induction cooker into protection state stopped working.
All intermediate frequency furnace service life of the intermediate frequency furnace taizhou stop? 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.
Intermediate frequency furnace steelmaking taizhou all the main points of the intermediate frequency furnace all stop? Answer: god light electric co. , LTD. Web site is introduced as follows: a, the task of smelting steel part of the main raw material is steel scrap and pig iron.
Outsourcing in scrap steel rust, with mud and other dirt, sulfur, phosphorus content in steel is higher also.
Steel's task is to put the above conditions of raw material of smelting gas and low inclusion content, composition of qualified, temperature meet the requirements of high quality.
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,
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.
