Abstract
The invention discloses the method for refining that a kind of steel water uses high-frequency vibration sublimate homogenization, it is after steel water injects ladle, ladle is placed on high-frequency vibrating table, adjusting amplitude is 0.5-1.0mm, frequency is to vibrate 60-150 seconds within the scope of 100-200Hz, escape gas, on impurity is floating, cast parts again after sublimate, homogenization.The invention has the advantages that the sublimate of steel water, homogenization method are easy to operate, securely and reliably, the time is quick；Refining equipment is low in cost, and small investment, operating cost is low, and with 5 kilowatt meters, shake table starts 120 seconds the vibrating motor power of high-frequency vibrating table needed for 5 tons of steel waters, and power consumption is 0.17 degree, just corresponds to the refining cost of 0.1 yuan；Steel water sublimate, uniformization effect are splendid, can pour the casting for casting out high quality.
Description
Technical field
The present invention relates to the refining of steel water, the specifically refining side that is homogenized by high-frequency vibration sublimate of steel water
Method.
Background technique
There are about 50,000 Foundry Works, the overwhelming majority thinks little of, does not implement the refining of steel water sublimate, but completes furnace in China
It is poured at once after interior melting.Therefore, in the case where chemical component indifference, the service performance and service life difference of casting
It is very big.The whole nation only has only a few Foundry Works to implement degasification removal of impurities in the packet of steel water stokehold, when traditional and existing method is tapping
Argon gas is passed through toward Bao Neijia " refining agent ", or from packet bottom.The former is molten to eliminate by the effect of elements certain in " refining agent "
Gas and impurity of the solution in steel water, there is certain clean-up effect, but it is at high cost, stirring operation is difficult, refining agent five spends eight
Door, influences steel water constituent, and steel water serious cooling in packet.The latter's effect is not very obvious, and what argon gas was passed through
Device is complicated and easily goes out safety problem, and air consumption is big, operates not safe reliable.
Summary of the invention
The invention aims to disclose a kind of method of refining that steel water uses high-frequency vibration sublimate to homogenize.
Realizing the technical solution of the object of the invention is:
A kind of steel water uses the method for refining of high-frequency vibration sublimate homogenization, is after steel water injects ladle, by ladle
It is placed on high-frequency vibrating table, adjusting amplitude 0.5-1.0mm, frequency is to vibrate 60-150 seconds within the scope of 100-200Hz, make gas
Evolution, on impurity is floating, cast parts again after sublimate, homogenization.
Vibration of the present invention is vibration strongly, and amplitude 0.5-1.0mm is equivalent to generation 100- per second
The strong stirring of 200Hz and the acceleration up and down of 100-200Hz are squeezed and are stretched strongly, make the gas being dissolved in steel water and
Steel water surface is floated on field trash is rapid, can not only achieve the effect that sublimate, homogenization, and can promote and force steel
The nucleus refinement come into being in water and increase, it is highly beneficial to the subsequent compact crystallization process being cast in after casting mold.
The invention has the advantages that
1. the sublimate of steel water, homogenization method are easy to operate, securely and reliably, the time is quick；
2. refining equipment is low in cost, small investment, operating cost is low, the vibrating motor function of high-frequency vibrating table needed for 5 tons of steel waters
Rate is started 120 seconds with 5 kilowatt meters, shake table, and power consumption is 0.17 degree, just corresponds to the refining cost of 0.1 yuan；
3. steel water sublimate, uniformization effect are splendid, the casting for casting out high quality can be poured.
Specific embodiment
The content of present invention is further elaborated below by embodiment.
Embodiment 1:
The vibration of ZG270-500 molten steel and depressed test
1. high-frequency vibrating table power of motor used in is 5kw, amplitude 0.8mm, frequency 130Hz, contains molten steel 3360kg in ladle, implements
Time of vibration 120 seconds；
2. when vibration, straight-forward phenomenon --- many small sprays of molten steel in molten steel surface dodge jump (gas overflowing) again and again, micro field trash is emerged
Liquid level；
3. being poured casting (5 casees, 15, every case, every 41kg), none equal gas hole defect after 75 appearances and processing, processing cutting
It is functional, crystallize fine and closely woven, yield strength 290MPa, tensile strength 553MPa；
4. same furnace molten steel is refined without high-frequency vibration, interior molten steel 346kg is wrapped, comes out of the stove and is poured same kind after first standing 2 minutes
It 75, casting, is compared through quality inspection:
Surface spilehole (Φ 2-5mm size) defect 13, gas hole defect 4 still visible after processing, Mechanical processing of casting cutting ability
Not as good as the former, its yield strength of mechanics properties testing 266MPa, tensile strength 505MPa.
Embodiment 2:
The vibration of HT250 molten iron and depressed test
1. shake table technical indicator is identical as preceding ZG270-500 test, molten iron 3116kg is filled in packet, implements time of vibration 120
Second；
2. 5 casees are poured, 21, every case, totally 106, part weight 26kg；
3. casting quality inspection: gas hole defect 2；Tensile strength 270MPa；Graphite form: A type is tiny；
4., without high-frequency vibration processing, wrapping interior standing with the HT250 molten iron 310kg of furnace melting and being poured similar casting after 2 minutes
106, quality inspection result: gas hole defect 16；Tensile strength 248MPa；Graphite form: A type+D type.
Claims (3)
1. a kind of method of refining of steel water sublimate homogenization, it is characterized in that: the 3-5 minute in steel water injection ladle
