Description
Technical field
The utility model relates to charging mechanism more particularly to a kind of material alloying mechanisms of vacuum induction furnace zone preservative pipe.
Background technique
Vacuum induction melting furnace generated in metallic conductor under vacuum conditions, using electromagnetic induction eddy heating for heating furnace charge come
Melting is carried out, the vacuum metling complete set of equipments of metal molten is made.Particular by the AC power source of certain frequency, it is generally divided into
Frequency and power frequency generate the magnetic field of an alternation when the electric current of alternation is by coil on crucible, and according to Ferrari electromagnetism sense
It answers this magnetic field of principle that can generate the eddy current for having certain depth in the material surface for needing melting, and then passes through this whirlpool
Metal material inside the heating and melting crucible of galvanic electricity stream.When the material of melting is ferrous metal material, it is in alternating magnetic field
In molten steel will receive the effect of electromagnetic force and generate relative motion, produce one further according to the distribution situation in magnetic field and similar stir
The effect mixed, so that molten steel be made to seethe, melting is abundant, and then the material for melting out and can be allowed more uniformly high-quality.
With the development of modern science and technology, especially modern aerospace, the rapid development of nuclear power, military project cause, very
Primary smelting equipment of the empty induction melting furnace as materials such as melting high-temperature alloy material, Precise Alloy material, super-high strength steels needs
It asks increasing, while requirement of the vaccum sensitive stove to raw material and smelting process is also higher and higher, is especially smelting the later period pair
The addition of alloy material, one of melting later period, that is, refining period main task is that adjustment molten steel component is also known as alloying, in deoxidation
It closes and deaerates in good situation, add some such as manganese, silicon, lanthanum, titanium, molybdenum, niobium, tantalum, tungsten alloying element into molten steel to adjust
Molten steel component, during vacuum metling, since the saturated vapor pressure of different-alloy is different, the sequence of alloy addition is not yet
Together, traditional charging process is directly to feed into charging bucket, opens vacuum lid, and loading channel directly is arranged in bell, adds
Charging basket falls into working chamber, and charging bucket is placed on above crucible after a distance, and charging barrel soleplate is melted by the high temperature of molten steel
Cotton cord or the rope made of hemp open charging barrel soleplate, alloy is fallen into molten steel, and on the one hand this traditional feed way is opened very every time
Empty bell, which directly feeds, can make air pollute the molten steel in furnace, seriously affect material composition, performance and the use of material
Service life, this feed way inefficiency of another aspect, because of the affinity size and volatile journey according to alloying element and oxygen
The different sequencings and condition is added that degree needs to determine to be added, this just brings up is added a kind of alloying element every time, needs every time
It wants vacuum breaker, vacuumize, and the limited alloy material for needing to be added required type within the limited time of melting later time, together
Shi Shangci charge melted charging basket baseplate temp is very high, and replacement charging bucket is extremely inconvenient every time, and inefficiency is it is also possible to influence
Manufacturing schedule, the loading channel of setting are directly entered furnace charge in furnace into channel is crossed, and furnace charge occurs to splash when entering molten steel to produce
Raw a large amount of dust, pollutes and blocks to vacuum pipe and vacuum pump, and safety accident even occurs when serious.Furthermore it splashes
Molten steel is solidifying to be attached on furnace charge channel, will also result in great waste on fire door and bell, and molten steel component is influenced.
