Abstract
The present invention relates to electromagnetic stirring roller for continuous metal casting, and is especially one kind of high magnetic field two cold plate blank electromagnetic stirring roller. The electromagnetic stirring roller includes a winding and a cylindrical iron core, and has shielding rings to mask the non-working surface. Adopting cylindrical iron core without teeth and slots results in high space utilization rate of the winding, increased magnetic conducting area of the iron core, raised magnetic field strength and enhanced electromagnetic stirring force. Shielding the non-working surface with shielding rings can minimize the magnetic leakage, increase the magnetic field strength in the working surface and enhance the electromagnetic stirring force.
Description
Technical field
The present invention relates to the electromagnetic agitation roller that uses in the continuous casting of metal technology, refer in particular to a kind of electromagnetic mixing roller of two cool areas of highfield unburnt earthenware.
Background technology
Slab two cold-zone electromagnetic agitation adopt following three kinds of forms usually: travelling-magnetic-field type behind a. roller, b. roll-type travelling-magnetic-field type, c. magnetic pole plug-in type travelling-magnetic-field type.What use was maximum now is back two kinds.Wherein roll-type travelling-magnetic-field type is owing to directly place electromagnetic inductor formation electromagnetic agitation roller in the backing roll, and profile is the same with conventional roller.Can be installed in very easily on the slab caster and do not change the structure of conticaster, thereby be easy to be accepted by the user.But owing to be subjected to the restriction of installing space in the roller, the inductor core section is less, thereby magnetic flux density is not high, and mixing power is less than normal.Existing electromagnetic agitation roller adopts E font iron core usually, the gram winding configuration that goes in ring.The electromagnetism roller of this structure has the following disadvantages: a. iron core teeth has accounted for bigger volume, makes the shared ratio of winding and core section reduce, and number of ampere turns and magnetic conductive area are little, so magnetic field is also little.B. distribution is dispersed in magnetic field around iron core, and leakage field is big, makes working face magnetic field reduce.E font spline iron core, the iron core magnetic conductive area that the belt winding configuration of gram is had is little, and magnetic resistance is big, and the defective that leakage field is big has badly influenced the result of use of electromagnetic agitation roller.
Summary of the invention
The objective of the invention is to be improved, a kind of magnetic flux density that can improve the electromagnetic agitation roller is provided, increase the electromagnetic mixing roller of two cool areas of highfield unburnt earthenware of electromagnetic stirring force at shortcoming that exists in the background technology and problem.
Technical scheme of the present invention is: construct a kind of novel core configuration and be provided with the electromagnetic mixing roller of two cool areas of highfield unburnt earthenware that magnetic covers the screen structure.It comprises winding and iron core, is characterized in that iron core adopts the not cylinder-shaped iron core of spline, and agitating roller is provided with ring shielding magnetism, and the ring shielding magnetism outer surface is a non-working surface, and the face that is sheltered from by ring shielding magnetism is not a working face.
The present invention changes E font iron core into the not cylinder-shaped iron core of spline, can improve the space availability ratio of winding to greatest extent, increases the magnetic conductive area of iron core, thereby increases magnetic field intensity, strengthens electromagnetic stirring force.Install ring shielding magnetism additional at agitating roller other faces except that working face, can prevent to greatest extent that magnetic field from revealing from non-power direction, thereby increase the magnetic field intensity of working face greatly, increase electromagnetic stirring force.

The specific embodiment
By Fig. 3,4 as can be known, the present invention includes winding (1) and iron core (2), be characterized in that iron core (2) adopts the not cylinder-shaped iron core of spline (2), agitating roller is provided with ring shielding magnetism (3), ring shielding magnetism (3) outer surface is a non-working surface, and the face that is sheltered from by ring shielding magnetism (3) is not a working face.
Winding of the present invention (1) at interval or be wound on the periphery of cylinder-shaped iron core (2) continuously.Described ring shielding magnetism (3) is set in the skin of winding (1) and cylinder-shaped iron core (2).Described ring shielding magnetism (3) has one worn-out mouthful, and worn-out mouthful of place's winding (1) is exposed to the outer agitating roller working face that is.Described iron core (2) is cylindrical, does not have tooth and groove.
The inventor by above method manufactured experimently one with the same big model machine of electromagnetic agitation roller appearance and size in the past.After tested, the working face magnetic field intensity has increased by 80%, and electromagnetic force has increased by 120%.Effect is quite obvious.The increase of mixing power, make the electromagnetic agitation roller both realize the advantage that magnetic pole plug-in type travelling-magnetic-field magnetic stirrer mixing power is big, metallurgical effect is good, keep the advantage that roll-type travelling-magnetic-field magnetic stirrer is easy for installation, with low cost, need not change the conticaster structure again, become the direction of slab two cold-zone magnetic stirrer development.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; be not that design of the present invention and scope are limited; do not breaking away under the preceding topic of design philosophy of the present invention; engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
