Abstract
The utility model relates to an electromagnetic stirrer, which mainly solves the electromagnetic stirring problem in the continuous casting operation. The utility model is characterized in that an inner part of a roller cylinder 1 is provided with an inner axle 2 of the roller cylinder and the inner axle is connected with a motor 5. The inner axle of the roller cylinder is provided with permanent magnets regularly arranged according to a spiral type along the axial direction. The permanent magnets can generate the induction field in a traveling wave type. The utility model is mainly used for the connection of the plate blank steel in the modern smelting technology.
Description
The utility model relates to a kind of electromagnetic mixing apparatus, is particularly useful in the continuous casting process of slab steel.
The magnetic stirrer that current domestic and international enterprise adopts mainly is to adopt the alternating current impression type, as IRSID-CEM company, Nippon Steel Corporation etc. succeed in developing all belongs to the alternating current impression type, because they comprise the linear electromagnetic agitator of several low-frequency currents, by big electric current, so the usage factor of energy low (generally having only 0.5～2% utilization rate), auxiliary equipment and power supply unit capacity are big, shortcomings such as maintenance, maintenance workload is big have limited the application of alternating current impression type magnetic stirrer.
The purpose of this utility model is to provide a kind of continuous casting energy-saving permanent-magnetism electromagnetic agitator, overcomes the shortcoming of above-mentioned alternating current impression type magnetic stirrer.
The utility model is achieved in that axle 2 in the roller in roller 1, it connects with motor 5, in roller, have vertically by spiral regularly arranged permanent magnet 6 on the axle, can produce the travelling-wave-type induced field, form electromagnetic force with the eddy current effect in the continuous casting steel billet molten bath, make the directed stirring of molten steel, reach the effect of electromagnetic agitation, cold water reaches cooling effect by entery and delivery port.
The utility model has the advantages that: 1. do not have coil in the agitator, do not need electric current, its power factor is low, does not need big power supply unit, and the rotating energy of driven by motor axle almost all is used to stir molten steel, and high efficient is arranged, and can save the energy in a large number.2. simple in structure, cost is low, does not need jumbo power supply unit, has advantages such as province's line, energy-conservation, life-span be long, is easy to apply.
Fig. 1 is its structural representation, and wherein 1 is roller, and 2 is axle in the roller, and 3 is bearing block, and 4 is entery and delivery port, and 5 is motor, and 6 is permanent magnet.
Below in conjunction with accompanying drawing invention is described further:
As everyone knows: the essence of electromagnetic agitation is to force MOLTEN STEEL FLOW in the steel billet molten bath by electromagnetic force, thereby improves the inherent quality of steel billet.The main effect of electromagnetic agitation is to reduce to be mingled with content, reduces central pipe, eliminates gross segregation, and axial ratio rates such as increase are improved the alloy effect of solidified structure.The invention is characterized in and utilize in the motor drives roller on the axle, make it produce the travelling-wave-type induced field vertically by the permanent magnet rotation of spiral arrangement
Variation in molten steel, produce eddy current again
With
And velocity
Vertical mutually, produce electromagnetic force
Act in the unit volume unit of molten steel, thereby form function composite by electromagnetic stirring.Since roller be enclosed within axle go up rotatable, space sealing therebetween and by the cooling water of certain pressure is arranged.Motor is positioned at its two ends, and motor and rotating mechanism make the reverse sync rotation exactly of contiguous two rollers, thereby makes molten steel form closed jet to stirring in the steel billet molten bath.
The utility model also can be applied in the electromagnetic agitation of other types continuous casting.
