Intermediate frequency electric furnace along the crack technology, an intermediate frequency electric furnace melting cast iron bravery why more and more small answer: what kind of lining material, is a question of lining.
With the decarburization process in medium frequency furnace smelting process, cupola melting can be avoided.
Using medium frequency furnace melting molten iron should be overheating to more than 1500 degrees, can improve the quality of molten iron, reducing chilling and the hardness of the casting.
But you can't copy the original process, chemical composition also felt need to adjust.
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 electric furnace before use should be detection electric circuit are in good condition, whether the element damage, the contact point is loosening and release, if have the above situation occurs should eliminate faults in rear can use.
Check intermediate frequency electric furnace water, water temperature, water quality, should meet the requirements of the device, the water temperature + 5 ℃ ~ + 40 ℃, the water pressure is 10 kg/cm2 ~ 20 kg/cm2.
What is the principle of intermediate frequency electric furnace?
A: intermediate frequency electric furnace is a kind of smelting equipment, not household electric furnace!
- - - - - -
Through the electromagnetic induction eddy current in the metal surface melt metal heating equipment, consists of furnace body, bus before furnace busbar, frequency conversion device, water cooling device, control of five parts.
Features: 1, the melting speed, metal components uniform,
2, low temperature around the stove, smoke less, make it.
How much is the frequency band of the intermediate frequency electric furnace, high frequency electric furnace?
High frequency electric furnace, intermediate frequency electric furnace along the crack a: also known as high-frequency heating machine, high frequency induction heating equipment, high frequency induction heating equipment, high-frequency heating power supply, high frequency power supply, high frequency electric furnace.
High frequency welding machine, high frequency induction heating machine, high frequency induction heater (
Medium frequency induction heating equipment, etc. , in addition, ultra-high frequency induction heating equipment, etc.
Frequency range in the 50 - high frequency electric furnace
Medium frequency electric furnace in the sudden power failure. What should I do answer: if there are any power failure, what method is used to see in what state power don't know everyone in the workpiece during induction hardening, if all of a sudden power outage, workpiece is how to deal with, not to continue and then quenching?
Direct start all over again, if hardness is too high, is only the annealing?
Parts technical requirements is not high, set aside a certain distance, continue to quenching.
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.
What is the advantage of intermediate frequency electric furnace smelting iron on medium frequency electric furnace along the crack a: medium frequency induction furnace
is a kind of will power frequency 50 hz alternating current into intermediate frequency (
More than 300 hz - 1000 hz)
Power supply device, the three-phase alternating current (ac) power frequency, after rectification into direct current, then laid adjustable intermediate frequency electric current, direct current supply by capacitance and induction coil in through the intermediate frequency alternating current, generate high density magnetic field lines in the induction coil, induction and cut.
What kind of job intermediate frequency electric furnace with high efficiency intermediate frequency electric furnace along the crack a: intermediate frequency electric furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency (
More than 300 hz - 10000 hz)
Power supply device is controlled by frequency conversion device, furnace, furnace before such a few parts.
Chinese intermediate frequency electric furnace equipment principle of three-phase power frequency alternating current into direct current advantage after rectifying element layout reasonable coordination, easy maintenance features low temperature around the stove.
Why intermediate frequency electric furnace shell leakage intermediate frequency electric furnace along the crack answer: generally there is no problem on insulation processing, intermediate frequency electric furnace shell should be no leakage.
Want to ask you: are you of intermediate frequency furnace aluminum shell furnace or steel shell furnace?
That's good to answer your question.
Intermediate frequency electric furnace along the cracking medium frequency furnace and electric furnace technical data than what's the difference?
A: a kind of intermediate frequency furnace is inside the furnace, furnace can be divided into intermediate frequency furnace, resistance furnace, electric arc furnace, and so on.
Intermediate frequency furnace will be compared with other energy conservation and environmental protection, and high heat energy utilization, recommend you a website, you can go to the 'divine radiation electric furnace' websites search the related information.
The difference between induction medium frequency furnace and electric furnace, which make steel?
The advantages and disadvantages?
Intermediate frequency electric furnace along the crack answer: actually not steelmaking with medium frequency furnace, is to melt the steel, the impurities in the steel can't take out, can only rely on slag.
This is a disadvantage.
Advantage is that it turns out that some elements of the steel basic don't loss, can reduce the amount of valuable elements to add, reduce the cost.
Arc furnace can be burnt up all the impurities in the steel scrap and precious metals, and then add the various elements as required.
Cast iron pan with why always cracking on the induction cooker?
Intermediate frequency electric furnace along the crack a: the working principle of induction cooker is: magnetic flux generated by the induction cooker of rapid change, cause the eddy current is generated in the metal pot then fever is not in the fire heat conduction, induction cooker is destroyed pot, general family expenses 3 ~ 4 months is about to change.
Thermal conductivity and the following three factors related to the thickness of the material of pan the same thickness and diameter of the diameter of the bottom of the pot of cast iron.
