Intermediate frequency furnace uds mixing technology, an intermediate frequency furnace steelmaking process, and the relevant matters needing attention!
2: feeding by furnace of work completed, at the time of loading, dropping material, melt faster, pay attention to have a seal can't add, of cold water as much as possible in the oven baked first, and pay attention.
What is the advantage of intermediate frequency electric furnace
smelting iron on 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 are the advantages of medium frequency furnace compared to natural gas heating furnace a: medium frequency 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 coil, and cutting.
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.
How to correctly choose medium frequency furnace crucible mold?
Answer: the intermediate frequency furnace crucible belongs to medium frequency furnace is an important part in the composition, so this part to be able to very good under high temperature, can also insulation and heat insulation, as well as for energy transmission between.
And crucible mold must have good anti scour and compressive capacity.
At the same time, the equipment and electrical characteristics of medium frequency furnace and can't.
Used to cast copper medium frequency furnace and power frequency furnace have why to distinguish?
A: intermediate frequency furnace and power frequency furnace has the following main difference: 1, intermediate frequency furnace power density is larger, high productivity, namely under the same stirring power, the same capacity, intermediate frequency furnace can be input 3 times the power frequency furnace power, in other words, the same power medium frequency furnace crucible size was only about a third of the power frequency furnace crucible size in large oven, because of the influence of the sensor wire Qing current and voltage.
Medium frequency coreless induction furnace coil daub made answer: main ingredients for alumina silica mica powder, then add some rust red color mixing, do add water painting after drying or crack, so the inside of the particles do not too big, but must have a proportion, all powder will crack.
Medium frequency furnace melting quality steel and alloy steel practical case how to do?
Answer: the AOD and VD/VOD furnace AOD the argon oxygen decarburization refining furnace, is a proprietary technology for stainless steel smelting.
A refining furnace, AOD argon oxygen equipment: 1, AOD furnace 2, 3, 4, AOD suspension AOD slag cover 5, and 6 AOD base, bearing and bearing 7, tilting furnace system drive eight AOD tilting accident driving mechanism, AOD method two features: *.
How to improve the quality of molten steel medium frequency furnace steelmaking?
Intermediate frequency furnace uds stirring a: just a melting scrap steel, medium frequency furnace smelting process without oxygen, such as refining slagging agent means, so the intermediate frequency furnace molten steel under the influence of PZH steel material, improve the steel quality is mainly in the intermediate frequency furnace after a few steps behind, namely refining outside the furnace and the quality control of continuous casting mould.
Why my intermediate frequency furnace hearth has been leaking!
Who can help ah!
Thank you very much!
Uds stirring a: intermediate frequency furnace hearth, whether some permanent layer preset vent to open, otherwise the moisture out, sintering furnace bottom are not reliable, easy to burn through.
First charge to choose better material, charging wants light, want to slowly increase power, in this way can is quartz sand sintering is good, strong and durable.
Bottom can be appropriately increasing point.
Intermediate frequency furnace uds mixing liquid medium frequency furnace roll technical data related to what factors uds stirring a: intermediate frequency furnace and medium frequency furnace of electromagnetic stirring.
Intermediate frequency furnace in ironmaking silting pan uds stirring a: what's going on intermediate frequency furnace heating principle of intermediate frequency furnace: induction coil through the alternating current, the alternating magnetic field, the alternating magnetic field on the inside of the heating element (
Alternating induction to produce alternating inductive electromotive force, resistance heating element itself to a certain extent, so have to form inductive current, also known as eddy current.
Vortex is the cause of the current penetration, the lines of magnetic force is uneven distribution in the coil.
Always wear in 500 kg of intermediate frequency furnace medium frequency furnace uds stirring a: you is a novice to use central quartz sand with 2% boric acid and 6% of the water!
Points several times to join in 30 kg timber drying at least eight hours, when used in furnace sundry pour clean!
The effect must be better than you.
