Description
Technical field
The present invention relates to a kind of continuous cast mold system, particularly relate to a kind of continuous casting electromagnetic stirrer, be applied to metal metallurgy smelting equipment technical field.
Background technology
Since electromagnetic agitation (Electromagnetic stirring:EMS) technology is come out, one of important correlation technique progressively developing into continuous casting steel machine field.The essence of magnetic stirrer is the electromagnetic force by inducting in casting blank liquid core, the motion of strengthening molten steel.Specifically, the alternating magnetic field that agitator excites penetrates in the molten steel of strand, just induces electric current wherein, this induced-current and local magnetic field interaction produce electromagnetic force, electromagnetic force is body force, acts on molten steel volume element, thus can promote molten steel motion.So just by electromagnetic force control molten steel in casting process flowing, heat transfer even solidify, thus make the surface quality of continuous casting billet and subcutaneous quality wait until obvious improvement, improve the cleannes of steel, expand the equiax crystal district of strand, reduce component segregation, alleviate or eliminate center porosity and central pipe, realizing the object of production high-quality, high-grade steel.
The design of tradition bar plate electromagnetic agitator is all coiling on iron core, produces the travelling-magnetic-field of certain area from the yoke of iron core, then stirs the molten steel of magnetic fields at certain area.One of subject matter that this traditional slab agitating device exists is that the region of magnetic fields is comparatively single, because the factor in structural design can only stir the molten steel in yoke region, stirring scope is fixed, when the molten steel of more wide region or less stirring scope will be stirred, need the agitator changing corresponding size, can not meet and use same agitator expand and reduce the scope of stirring, in industrial processes, seem loaded down with trivial details, and the cost changing agitator is high.
Summary of the invention
In order to solve prior art problem, the object of the invention is to the deficiency overcoming prior art existence, a kind of sheet billet continuous casting magnetic stirrer of the controlling magnetic field zone of action is provided, when not changing agitator, magnetic fields region can be changed, can expand and reduce magnetic fields region, simple to operate, save cost.
Create object for reaching foregoing invention, the present invention adopts following technical proposals:
A kind of sheet billet continuous casting magnetic stirrer of the controlling magnetic field zone of action, comprise magnetic stirrer iron core and coil, coil winding is on magnetic stirrer iron core, yoke place outside magnetic stirrer iron core adopts and opens dress mode correspondence fixed installation silicon steel, silicon steel adopts a series of silicon steel sheet to be formed by stacking, according to the zone of action size applying electromagnetic agitation to the metal bath in sheet billet continuous casting magnetic stirrer, select the silicon steel sheet determining size needed for specification, and be assembled into corresponding size, the silicon steel of shape and thickness, by the installation site of adjustment silicon steel relative to the yoke place outside magnetic stirrer iron core, the size of silicon steel, shape and thickness, and then the zone of action of magnetic field to metal bath is expanded, reduce and move adjustment with position, silicon steel is also fixedly connected with copper pipe is set, pass into recirculated water to copper pipe to dispel the heat to silicon steel.
As the preferred technical scheme of the present invention, silicon steel is fixedly mounted on the yoke place outside magnetic stirrer iron core by screw.
As preferred technical scheme further in technique scheme, copper pipe is fixed on silicon steel by welding manner.
The present invention compared with prior art, has following apparent outstanding substantive distinguishing features and remarkable advantage:
1. the present invention has added silicon steel in the outside of agitator corresponding to yoke place, expand by designing the size of silicon steel, shape and thickness and reduce magnetic fields region, thus changing magnetic fields region when not changing agitator, structure is simple, easy for installation, save cost;
2. silicon steel of the present invention is formed by stacking by silicon steel sheet, and be provided with water-cooling system to silicon steel increase, can prevent the generation of eddy current like this, avoids silicon steel temperature too high, improves the job stability of sheet billet continuous casting magnetic stirrer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sheet billet continuous casting magnetic stirrer of the preferred embodiment of the present invention controlling magnetic field zone of action.
Detailed description of the invention
Details are as follows for the preferred embodiments of the present invention:
In the present embodiment, see Fig. 1, a kind of sheet billet continuous casting magnetic stirrer of the controlling magnetic field zone of action, comprise magnetic stirrer iron core 1 and coil 2, coil 2 is wrapped on magnetic stirrer iron core 1, yoke place outside magnetic stirrer iron core 1 is adopted by screw and opens dress mode correspondence fixed installation silicon steel 3, silicon steel 3 adopts silicon steel sheet to be formed by stacking, according to the zone of action size applying electromagnetic agitation to the metal bath in sheet billet continuous casting magnetic stirrer, select the silicon steel sheet determining size needed for specification, and be assembled into corresponding size, the silicon steel 3 of shape and thickness, by the installation site of adjustment silicon steel 3 relative to the yoke place outside magnetic stirrer iron core 1, the size of silicon steel 3, shape and thickness, and then the zone of action of magnetic field to metal bath is expanded, reduce and move adjustment with position, silicon steel 3 is fixedly connected with by welding manner copper pipe 4 is set, pass into recirculated water to copper pipe 4 to dispel the heat to silicon steel 3.
In the present embodiment, see Fig. 1, silicon steel 3 is formed by stacking for silicon steel sheet, and the magnetic induction intensity of this material is the most desirable, can be prevented the generation of eddy current, avoid silicon steel temperature too high by lamella superposition.Water flowing in the copper pipe of spot welding on silicon steel 3, avoids silicon steel overheated like this and endangers agitator.The size of silicon steel 3, shape and thickness adjustable, excite the magnetic field comprehensive that will obtain in magnetic field and crystallizer determine and adjust according to agitator, when we need to stir wider region, can by the enlarged leather area of silicon steel 3, by screw, silicon steel 3 being fixed on yoke place, obtaining the magnetic field that we need like this when not changing agitator.In like manner, when we need to reduce stirring scope, can silicon steel 3 area be done little.The present embodiment adds silicon steel 3 at bar plate electromagnetic agitator iron core yoke place, by the zone of action regulating silicon steel 3 to change magnetic field, carry out expanding, reduce, on move, move down, move to left, move to right magnetic fields region, the present embodiment is under the prerequisite not changing agitator, the magnetic fields region in crystallizer can be changed, structure is simple, easy to operate, saves cost.
