Background technology
Magnetic stirrer is used for about 50 years on conticaster, and guarantee is provided for steel product quality, has been refining
The standard configuration of steel conticaster.But magnetic stirrer has born defect.
The apparent energy of general separate unit magnetic stirrer is that large energy consumption in steel mill equips it between 200 ~ 600KVA
One, and efficiency is less than 30%, a large amount of electric energy all becomes the coil Joule heat water that is cooled and takes away.Especially at casting blank solidification end
End, because plant capacity is big, while blender, by the radiation heat affecting of strand, coil must use the pure water cooling of big flow.
Conducting wire is water-cooled, and brings a series of troubles：Cooling water, which must be pure water, coil insulation ag(e)ing, causes stirrer life general
No more than 1 year.
The permanent magnetic stirrer for manufacturing and designing conticaster, is the dream of many people, since magnetic stirrer is born, is occurred as soon as
The imagination of permanent magnetic stirrer, does not there is commercial Application unfortunately.
A kind of hydraulic drive continuous casting permanent magnetic stirrer designed by Zhang Senlin and Li Bing（The patent No. 2,010 2
0032017.2）, because having abandoned the driving method of other schemes so that permanent magnetic stirrer can be promoted on conticaster and be answered
With.But, which is primarily adapted for use in conticaster crystallizer built-in type permanent-magnet blender.In scheme designed by the patent, magnetic
Body and hydraulic motor are within the protection of conticaster crystallizer cooling water, and the safety problem of component especially magnet is not present.
And permanent magnetic stirrer is used in casting blank solidification end, in face of caster two cold room between withdrawal straightening machine 10000The high temperature spoke of C or more
It penetrates and high temperature shower water, it is necessary to have new more perfect technical solution, to ensure permanent magnetic stirrer in continuous casting billet solidifying end area
Section reliability service.

It closes；It is equipped with hydraulic motor in the outer surface of the double-deck outer barrel；It is equipped with driven gear, driven gear and master in the outer surface of upper of yoke
Moving gear engages, and drives driving gear and driven gear that magnet rotation is made to generate rotating excitation field by hydraulic motor；In hydraulic pressure
Motor and the double-deck outer barrel at gear drive position are equipped with Double layer motor cover.
The magnet is using rare earth high-strength field magnets opposite disposed two magnetic grade N-S.
The shape of the yoke is tubular yoke.
The magnet steel is the high magnet steel of rare earth material, and shape is that integral curved or fritter is assembled into quasi- arc, per side arc
The interior arc length of shape magnet steel is inside between the 1/8-1/4 perimeters of circle.
The double walled floor, the double-deck inner cylinder, the double-deck top plate, the double-deck outer barrel inner cavity be full of cooling water, cooling water passes through
Pipeline enters double walled floor to the double-deck inner cylinder to the double-deck top plate to the double-deck outer barrel to water outlet from water inlet.
The Double layer motor cover by pipeline from the double-deck top plate diversion, into inner cavity after bilayer is discharged by another pipeline
Outer barrel.
The magnetic field of the present invention is provided by the high magnet steel of rare earth material, and magnet steel forms N-S pole pairs, magnetic pole-yoke bearing
It is combined with bearing block, motor function is provided, and the double-deck inner cylinder of bearing block and blender, the double-deck outer barrel, the double-deck top plate and double
Layer bottom plate fastening combines.The gear installed in yoke is engaged with the gear of hydraulic motor end, in the case where hydraulic motor drives, magnet
It is pivoted, the strong magnetic field of rotation evokes induced field, externally-applied magnetic field and the magnetic field phase incuded in the wick-containing of strand
Interaction, according to lorentz principle, the sticky molten steel of solidification end generates the movement consistent with applying rotating magnetic field direction, and reaches
To stirring purpose.
The magnet of the present invention uses rare earth high-strength field magnets, is to consider that solidification end wick-containing is small and large viscosity, needs strong
Magnetic field drives.
For this particular surroundings of solidification end, the present invention provides to magnet, installation secure component and driving part one
The reliable protection scheme of kind, i.e., the described component all cooled water conservations, is allowed to completely isolated with external high temperature high humidity environment, with
Ensure magnet safety without demagnetizing.
