Description
Technical field
The invention belongs to metallurgical category, more particularly to a kind of continuous cast mold to feed steel band system, can be not only used for continuous casting billet,
Available for liquid metal alloy smelting and denaturation treatment.
Background technology
Crystallizer feeds steel band system and certain thickness flexible strip is fed crystallizer, is inhaled using the melting of steel band in the melt
Heat, changes the temperature field of melt in crystallizer, reduces the degree of superheat and temperature field temperature gradient of melt in crystallizer, utilizes at the same time
The mechanical movement of steel band crushes melt arborescent structure, increases the equiax crystal of grain growth, is to improve strand equiaxial crystal ratio, real
A kind of now possible technique of nearly equiax crystal strand, it is loose to the strand segregation that easily occurs in continuous casting process, the defects of crackle
Fine improvement result can be played.
The continuous cast method and implementation of patent WO2004012882A1, including continuous casting of metals crystallization apparatus, to crystallizer
Feed the component of molten metal.The mechanism assembly of cold material can be consumed by being fed to molten metal, and make contactless electric and magnetic oscillation type
The cold material that consumes of formula forces resonance source.Ensure that in above-mentioned method using contactless electromagnetic vibrator can consume cold material foot
Enough big amplitudes, hereby it is ensured that the rapid melting of cold material, reducing molten metal temperature, accordingly improves continuous casting ingot structure.But
Some shortcomings are have also discovered using the above method：（1）Cold material volume can be consumed and it is difficult to ensure that in casting process by being difficult to quick-replaceable
The uninterrupted of cold material can be consumed to feed；（2）The above method for continuous casting ingot structure impact effect with electromagnetic vibrator it is opposite
The change in location on crystallizer molten metal surface and change；（3）It is not very steady that cold material, which can be consumed, and run in guide pipe；（4）Steel
Band feed quantity is not suitable for often causing strand core rarefaction defect.
The content of the invention
It is contemplated that providing a kind of fast changeable steel band in place of overcome the deficiencies in the prior art, ensure casting process
Middle steel band is uninterruptedly steadily fed, and prevents opposite direction transmission of the vibrational energy to melt, and drawing is stablized, and casting metals cooling is equal
Even, the suitable continuous cast mold of steel band feed quantity feeds steel band system.
In order to solve the above technical problems, what the present invention was realized in.
Continuous cast mold feeds steel band system, it includes guide pipe, electromagnetic vibrator, pans and crystallizer；Steel band is from leading
Crystallizer is entered back into pipe into electromagnetic vibrator, steel band is sent into crystallizer；Molten metal is constantly passed through with from pans
Between pot bottom fix the immersed nozzle of mating and be sent into crystallizer, the semifinished product for processing in next step constantly drawn from crystallizer
Go out；When being sent into steel band to crystallizer, the steel band is assigned with mandatory resonance by the iron acting electromagnetic vibrator of electromagnetism；Institute
State guide pipe and use "] " type；Sealing fixture is fixed with the longitudinal opening of the guide pipe；One end of the fixture can be around
Shaft rotates, its other end connects through locking notch with locking member.
As a preferred embodiment, the present invention from the electromagnetic vibrator lower roll wheel axle center along discharging direction into crystallizer
The distance L on molten metal surface=（n-1）λ/2；Wherein：N is any integer；λ is steel band resonance wave wavelength.
As another preferred solution, the sectional area of feeding steel band of the present invention and the ratio of strand sectional area are 0.8
~1.5%.
The present invention by using] type guide pipe and be fixed with the longitudinal opening of guide pipe the combination knots such as sealing fixture
Structure, steel band can be quickly taken out, and can guarantee that the stationarity to metal bath feeding steel band.The present invention is from the electromagnetic vibration
Dynamic device lower roll wheel axle center along discharging direction molten metal surface into crystallizer distance L=（n-1）λ/2 can ensure casting process
Normal table, will not cause fluctuation in crystallizer metal surface, it also avoid consuming condensation upper gold when cold material is sent into molten metal
Belong to.The ratio of the sectional area and strand sectional area of feeding steel band of the present invention is 0.8~1.5%, by studying different feeding ratios
Steel band feeding influences continuous casting billet structure, is fed to feeding the suitable of steel band in molten steel crystallizer than being 0.8~1.5%, excessive feeds
Enter than strand core rarefaction defect can be caused.
