Specific embodiment
With reference to the accompanying drawings and detailed description the adjustable electromagnetism of the stirring region of the present invention is stirred
Mix device and method to be described in further detail, but not as a limitation of the invention.
As described in Figure 1, coil 3 is wound on the iron core 4 with teeth groove and constitutes magnetic field generation
Device, is one group per three coils, and its lead-out wire is connected with corresponding phase-change switch 2, by power supply 1
It is powered.So, by the closed and disconnected of each phase-change switch 2 of control, control energising
Coil number, so as to control the size of the stirring region to slab.
For example, by 1～No. 3 of the close one end on the iron core 4 of the side in the wide face 5 of crystallizer
Phase-change switch that coil is connected 2 is disconnected with power supply 1 and will be close to the 28～30 of the other end
The phase-change switch 2 connected by number coil is disconnected with power supply 1, and other phase-change switches 2 are all closed.
By the energising situation of the coil 3 on the iron core 4 of the opposite side in the wide face 5 of crystallizer and position therewith
The energising situation for putting corresponding coil 3 does identical process.So so that electromagnetic agitation
The width of stirring region is roughly the same with the distance of No. 4 coil to No. 27 coils, stirring now
The width in region is less than the length in the wide face of crystallizer.
Therefore, by with upper type, each phase-change switch 2 can be controlled according to the width of slab
Closed and disconnected so that the size of stirring region is matched with the width of slab.
On the other hand, can also be come by the phase place of the input of each phase-change switch 2 of control
Control the magnetic direction of each coil 3, so as to control each agitating unit corresponding with each coil 3
Mixing direction.Agitating unit refer on the iron core 4 of both sides corresponding two coils 3 in position it
Between one block of molten steel 7 sub- stirring region.
For example, by 4～No. 6 coils on the iron core 4 of the side in the wide face 5 of crystallizer and 25～
The phase sequence of the phase-change switch 2 of No. 27 coil connections is set to U, V, W, crystallizer opposite side
Iron core 4 on 4～No. 6 coils and the connection of 25～No. 27 coils phase-change switch 2 phase sequence
Be set to W, V, U in contrast so that 4～No. 6 coils and 25～No. 27 coils institute right
The mixing direction of the agitating unit that answers forms corner stirring region 9 for counterclockwise, that is,.Meanwhile,
By the phase sequence of the phase-change switch 2 of 7～No. 24 coils connection on the iron core 4 of side be set to W,
V, U, the phase sequence of the phase-change switch 2 of 7～No. 24 coil connections on the iron core 4 of opposite side set
It is set to U, V, W so that the mixing direction of the agitating unit corresponding to 7～No. 24 coils is suitable
Clockwise, that is, form main stirring region 8.
Therefore, it can the phase sequence by controlling each phase-change switch, so as to the stirring side of agitating unit
It is the to so that the mixing direction of multiple agitating units corresponding with the two of slab corner positions
One direction, forms corner stirring region 9, multiple agitating units corresponding with the medium position of slab
Mixing direction be second direction, form main stirring region 8.Wherein, first direction and second party
To conversely, corner stirring region 9 can form effectively stirring, main stirring area to the corner of slab
Wick-containing can be goed deep in domain 8, play preferable mixing effect.
Certainly, it will be appreciated by persons skilled in the art that the stirring region of slab can not also
Main stirring region 8 and corner stirring region 9 is distinguished, i.e., the phase sequence of all of phase-change switch 2 is homogeneous
With the mixing direction of whole stirring region is consistent.
Wherein, the coil for forming corner stirring region 9 and the coil for forming main stirring region 8 can
Powered by power supply A and power supply B respectively.Power supply A and power supply B adopt simultaneous techniques, can
Ensure two power supplys while startup, commutation and stopping.And then guarantee crystallizer flow field state
Stable.
As the coil for forming corner stirring region 9 is powered by power supply A, main stirring region is formed
8 coil is powered by power supply B, therefore, it can the input by adjusting power supply A and B respectively
Size of current, to adjust the stirring intensity of corner stirring region 9 and main stirring region 8 respectively.
