Abstract
The utility model relates to an electromagnetic slab stirrer with a movable narrow-edge iron core and belongs to the technical field of metal continuous casting process. An iron core is added on the narrow edge of the electromagnetic slab stirrer and is movable to the left and right along the wall of a crystallizer on the narrow edge. The narrow-edge iron core is bonded to the crystallizer on the narrow edge and connected to the wall of the crystallizer on the wide edge through a slide rail. The iron core is made of superposed silicon steel. The narrow-edge iron core makes traveling wave magnetic field to generate a magnetic loop at the narrow edge and reduces magnetic leakage. The narrow-edge iron core is movable to the left and right along the wall of a crystallizer on the narrow edge, which allows the narrow-edge iron core to stir slabs different in width without changing the crystallizer. Compared with a common electromagnetic slab stirrer, the stirrer improves the stirring efficiency on the narrow edge and improves the texture of casting blanks. The electromagnetic slab stirrer saves the cost for replacing the crystallizer, and is simple for operation and convenient for use.
Description
Technical field
The utility model relates to a kind of narrow limit iron core movable-type slab magnetic stirrer, belongs to metal continuous cast technology field.
Background technology
Since electromagnetic agitation (being called for short EMS) technology is come out, progressively developed into one of the important correlation technique in continuous casting steel machine field.Utilize multi-form field generator for magnetic to produce alternating electromagnetic field in crystallizer, when the liquid metal in the continuous casting billet passes through alternating electromagnetic field, produce induced current in liquid metal, the effect of induced current and magnetic induction intensity produces electromagnetic force.Control molten steel flow in the casting process, conduct heat even solidify by electromagnetic force, thereby make the surface quality of continuous casting billet and subcutaneous quality wait until tangible improvement, improve the cleannes of steel, enlarge the equiax crystal district of strand, reduce component segregation, alleviate or eliminate center porosity and central pipe, realize the purpose of production high-quality, high-grade steel.
Operation principle and the normal asynchronous of magnetic stirrer are similar, all follow two basic laws: electromagnetic induction and current and magnetic field interaction, namely working as molten steel is in the alternating magnetic field, produce induced-current within it, this electric current and externally-applied magnetic field interact and produce electromagnetic force, promote the molten steel motion.So reasonably electromagnetic mixing apparatus plays crucial effects to the quality of steel.
The design of traditional slab magnetic stirrer all is that broadside is coiled by iron core and forms, and produces travelling-magnetic-field, narrow limit Open architecture.The travelling-magnetic-field that two broadside iron cores produce is opposite to the motion of narrow limit and direction.One of subject matter that this traditional slab agitating device exists is that narrow limit does not add screening arrangement and can not make travelling-magnetic-field form the magnetic field closure at place, narrow limit, the leakage field phenomenon is very serious, influence the effective rate of utilization that EMS excites magnetic field, the low continuous casting billet structure of stirring efficiency is bad; The 2nd, general magnetic stirrer can only stir the strand of single size, when changing the slab of different in width, need change the agitator of corresponding size, the slab that uses same agitator to stir different in width be can not satisfy, complex operation, cost height like this changed.
The utility model content
In order to solve above-mentioned existing in prior technology problem, the purpose of this utility model provides a kind of narrow limit iron core movable-type slab magnetic stirrer, can improve magnetic field, narrow limit utilization rate, reduces leakage field.And under the situation of not changing agitator, stir the slab of different in width, and simple to operate, save cost.
For achieving the above object, the utility model adopts following technical scheme:
A kind of narrow limit iron core movable-type slab magnetic stirrer comprises the broadside iron core, coil, broadside Cu crystallizer wall, narrow limit Cu crystallizer wall and narrow limit iron core; Described coil is wrapped on the broadside iron core, described broadside Cu crystallizer wall is arranged on the centre of slab magnetic stirrer, described narrow limit Cu crystallizer wall and narrow limit iron core are bonded together, connect by slide rail and to be installed between the broadside Cu crystallizer wall, described narrow limit Cu crystallizer wall and narrow limit iron core by slide rail can be in broadside Cu crystallizer wall the broad ways move left and right.
Above-mentioned broadside iron core and narrow limit iron core are that silicon steel sheet is formed by stacking.
Compared with prior art, the utlity model has and tell down substantive distinguishing features and progress:
The utility model has added removable iron core on the narrow limit of agitator, iron core is to be formed by stacking by silicon steel, make its travelling-magnetic-field that in whipping process, produces form magnetic in narrow edge regions and close the loop, less leakage field, thereby improve the magnetic field of narrow edge regions, improve this regional stirring efficiency and improve tissue, prevent the formation of some defectives; Simultaneously the iron core installed of this place, narrow limit and the enough move left and right of narrow limit Cu crystallizer wall energy and connects by track with broadside Cu crystallizer wall just can stir the slab of different in width under the situation of not changing agitator, and be easy to operate, the saving cost.
Description of drawings
Fig. 1 is the schematic diagram of the narrow limit of the utility model iron core movable-type slab magnetic stirrer.
The specific embodiment
After now the specific embodiment of the utility model device being described in by reference to the accompanying drawings.
As shown in Figure 1, a kind of narrow limit iron core movable-type slab magnetic stirrer comprises broadside iron core 1, coil 2, broadside Cu crystallizer wall 3, narrow limit Cu crystallizer wall 4 and narrow limit iron core 5; Described coil 2 is wrapped on the broadside iron core 1, described broadside Cu crystallizer wall 3 is arranged on the centre of slab magnetic stirrer, described narrow limit Cu crystallizer wall 4 and narrow limit iron core 5 are bonded together, connect by slide rail and to be installed between the broadside Cu crystallizer wall 3, described narrow limit Cu crystallizer wall 4 and narrow limit iron core 5 by slide rail can be in broadside Cu crystallizer wall 3 the broad ways move left and right.
Described broadside iron core 1 and narrow limit iron core 5 are for silicon steel sheet is formed by stacking, and the magnetic induction intensity of this material is the most desirable.Narrow limit iron core 5 is bonded on the narrow limit Cu crystallizer wall 4, both are installed between the broadside Cu crystallizer wall 3 by the slide rail connection, in the electromagnetic agitation process, can change travelling-magnetic-field in the path at place, narrow limit, reach the closed-loop path, magnetic field, reduce leakage field and improve stirring efficiency acquisition favorable tissue.Narrow limit iron core 5 and narrow limit Cu crystallizer wall 4 can move left and right by slide rail at width in whipping process, purpose is the stirring that can satisfy under the situation of not changing agitator the different in width slab, when being transformed into by little width slab when stirring big width slab, only need narrow limit iron core 5 and narrow limit Cu crystallizer wall 4 are outwards moved, just can satisfy sheet slab and stir.Only need when in like manner needing to stir little width slab narrow limit iron core 5 and narrow limit Cu crystallizer wall 4 toward interior movements, simple to operate, save cost.
