Abstract
The utility model relates to a continuous casting mould. A non-equal gap soft contact electromagnetic continuous casting mould comprises a mould body(1), an inductive coil(2), a distinguishing body(3), a gap(4) between distinguishing bodies and an inductive coil tap(5). The inductive coil surrounds the distinguishing bodies which are equal and have different gaps. From the inductive coil tap at the upper part of the inductive coil, the gap in 0 to 90 degrees is at least one third of the joint cutting width, and gap in 90 to 180 degrees is at least two third of the joint cutting width, while gap in 180 to 360 degrees is the joint cutting width. The utility model, with even magnetic field in the mould and even stress on the molten metal meniscus as well as even and smooth casting powder, obtains perfect electromagnetic continuous blank with smooth surface and even quality; besides, the utility model has simple structure and obvious effect, thereby being applicable to such electromagnetic continuous casting mould as round blank, rectangular blank and plate blank.
Description
Technical field
The utility model relates to the continuous casting technology of steel, relates in particular to continuous cast mold.
Background technology
In the continuous casting steel machine process, the mechanical oscillation of crystallizer are the inflows that guarantees covering slag, and steady and continuous is produced indispensable equipment, and it is again the basic reason that produces the casting billet surface oscillation mark simultaneously.In recent years, outside crystallizer, apply high frequency magnetic field, the casting billet surface oscillation mark alleviated, quality be improved significantly the soft-contact electromagnetic continuous casting technology obtained the exploitation.So-called soft contact is that the split body continuous cast mold is applied high frequency magnetic field; produce an electromagnetic pressure that points to strand inside in the initial solidification district; this electromagnetic pressure partial offset the static pressure of molten steel; make motlten metal meniscus projection; be contactless state between the motlten metal at meniscus place and the crystallizer, the covering slag flow channel broadens, the even Channel Group of covering slag; thereby alleviated owing to mold oscillation, covering slag flows into, flows out the dynamic pressure variation that is caused and the casting billet surface oscillation mark that causes.Through fundamental research and simulated experiment, verified under the effect of high frequency magnetic field, continuous casting billet surface oscillation mark alleviates, and surface quality is improved.Yet; the soft-contact electromagnetic continuous casting crystallizer is owing to be a kind of joint-cutting split body; and between each joint-cutting and all be equidistant between the split body; but the induction coil that crystallizer applies outward is but because induction coil tap cause (referring to Fig. 3); cause at the magnetic induction intensity of crystallizer upper induction coil tap place bigger than normal; the suffered electromagnetic force size of the molten steel at meniscus place is heterogeneous; thereby cause the motlten metal at meniscus place and the noncontact distance between the crystallizer; it is unequal to be that covering slag flows into the degree of depth, cause the cc billet surface quality fashion, the time bad unstable.
Summary of the invention
The utility model has overcome soft-contact electromagnetic continuous casting crystallizer intrinsic inductance inequality and has caused the suffered electromagnetic force defective heterogeneous of molten steel at meniscus place, the more uniform non-impartial slit of a kind of crystallizer intrinsic inductance soft-contact electromagnetic continuous casting crystallizer is provided, be implemented in the soft-contact electromagnetic continuous casting steel machine process, the electromagnetic pressure equalization that meniscus is subjected to, thereby the zero defect continuous casting electromagnetic base of acquisition smooth surface homogeneous, high-quality.
The utility model is achieved in that a kind of non-impartial slit soft-contact electromagnetic continuous casting crystallizer, comprise slit between crystallizer body, induction coil, split body, split body, induction coil tap, induction coil surrounds split body, its inventive point is the split body equalization, the slit is unequal between split body, from the induction coil tap on induction coil top is starting point, slit width is 1/3 joint-cutting width in 0 to 90 °, slit width is 2/3 width of slit in 90 ° to 180 °, and slit width is a width of slit in 180 ° to 360 °.
The utility model operation principle be for the induced field intensity that remains in the soft-contact electromagnetic continuous casting crystallizer even; the split body equalization of employing in crystallizer; and the unequal kerf structure of slit width degree between split body; make the Distribution of Magnetic Field in the crystallizer even; the motlten metal meniscus is stressed evenly; promote the even Channel Group of covering slag, thereby obtained the high-quality continuous casting electromagnetic base of smooth surface, quality homogeneous.The utility model is simple in structure, effect is obvious, is applicable to continuous casting electromagnetic crystallizers such as round base, square billet, slab.
Description of drawings
Fig. 1 is the non-impartial slit of a utility model soft-contact electromagnetic continuous casting crystallizer circular body structural representation, and Fig. 2 is the square body construction schematic diagram of non-impartial slit soft-contact electromagnetic continuous casting crystallizer, and Fig. 3 is an impartial slit soft-contact electromagnetic continuous casting crystallizer.
Among the figure: 1 crystallizer body (circular, square), 2 induction coils, 3 slits, 4 split bodies, 5 induction coil taps,
Embodiment
A kind of non-impartial slit soft-contact electromagnetic continuous casting crystallizer, comprise crystallizer body 1, induction coil 2, split body 3, the slit 4 between split body, induction coil tap 5, induction coil 2 surrounds split body 3, split body 3 equalizations, slit 4 is unequal between split body, the width of slit in slit 4 (h) is 0.5 to 3 millimeter between split body, from the induction coil tap 5 on induction coil 2 tops is starting point, slit width is 1/3 joint-cutting width (h) in 0 to 90 °, slit width is 2/3 width of slit (h) in 90 ° to 180 °, and slit width is width of slit (h) in 180 ° to 360 °.
The non-impartial slit of the utility model soft-contact electromagnetic continuous casting crystallizer is the key technology that realizes smelting-continuous casting and direct rolling abbreviated system and zero defect continuous casting steel machine.By the joint-cutting to the crystallizer unequal-interval, the Distribution of Magnetic Field that reaches in the crystallizer is even, the stressed purpose of the same size of meniscus, thus can obtain smooth surface, the soft-contact electromagnetic continuous casting base of quality homogeneous.
