Abstract
The utility model relates to a meniscus-free electromagnetic crystallizer which is composed of a crystallizer, a heat preservation device and a high-frequency inductor. The heat preservation device is arranged at the upper part of the crystallizer. Simultaneously, the outer side of the upper part of the crystallizer is additionally provided with the high frequency inductor. The utility model is provided with a free meniscus in the crystallizer and has the advantages that crystallization conditions are improved, the quality of a casting blank is enhanced, etc.
Description
The utility model belongs to a kind of metallurgy ingot casting equipment, particularly a kind of crystallizer of liquid metal continuous pouring moulding.
All there is a molten steel meniscus surface area in existing strand process above crystallizer.Owing to meniscus is arranged, has then influenced first scull, thereby had a strong impact on the quality of strand.The Electro-Magnetic Metallurgy technology is to apply high-frequency alternating magnetic field by the meniscus surface area at molten steel, and the liquid towards metal produces inside electromagnetic push, thereby improves the just formation and the growth conditions of scull, thereby reaches the purpose of improving slab quality.
The purpose of this utility model is to provide a kind of electromagnetic crystallizer that does not have meniscus.
The utility model is realized by following scheme.
The utility model adds an attemperator above crystallizer.Thereby there is not meniscus in the scope that the first scull of metal in crystallization process produced, simultaneously added a high-frequency inductor and applied high-frequency alternating magnetic field in the crystallizer upper outside, make it the liquid towards metal and produce inside electromagnetic push, thereby improve first scull generation, growth and with the contact condition of crystallizer wall, reach the purpose of improving strand outside and internal soundness.
The utlity model has no meniscus in the crystallizer, improve crystallization condition, improve the advantage of slab quality.
Further narrate content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model;
Among the figure: 1 attemperator, 2 crystallizers, 3 high-frequency inductors, 4 strands.
Embodiment: the billet continuous casting with 100 * 100 (mm) is an example, crystallizer 2 tops are the attemperator that insulation material is made, attemperator 1 tightly is assembled together with crystallizer 2, high-frequency inductor 3 is induction coils of making for the square copper pipe of 15 * 10 (mm), feeding frequency to induction coil 3 during work is the high frequency electric of 20Khz, produces high-quality strand 4 under the normal running conditions.
Claims (2)
1, a kind of electromagnetic crystallizer that includes crystallizer at interior no meniscus is characterized in that the top of this crystallizer has added an attemperator, and has added a high-frequency inductor in the crystallizer upper outside.
2, a kind of electromagnetic crystallizer that includes crystallizer at interior no meniscus according to claim 1 is characterized in that said attemperator made by insulation material, be in crystallizer the top and with tight being assembled together of crystallizer.
