Abstract
The invention relates to a kerf-valving external water-cooled type electromagnetic soft contact continuous casing crystallizer, comprising a kerf copper pipe (1), an upper-section inner water jacket (3), a lower-section inner water jacket (2), an electromagnetic induction coil (4), a shell (8), an upper flange (9) and a lower flange (10), wherein the shell (8), the upper flange (9) and the lower flange (10) constitute a crystallizer assembly structure; the upper-section inner water jacket is made of engineering plastics and is sleeved in the electromagnetic induction coil; a groove (12) is machined on the outer wall of the outer wall surface of the kerf copper pipe along each kerf (5); a high-temperature resisting insulation sheet (11) is inserted into each kerf; bonding glue (120) is coated and filled in the groove; the edge of the inserted tail end of the insulation sheet slightly protrudes out of the bottom plane of the groove; and the high-temperature resisting insulation sheets and the serf copper pipe are fixed by the binding glue. A top rib sealing bar (8) which aims at each kerf is arranged between the outer wall of the kerf copper pipe and the upper-section inner water jacket. The invention has the advantages of strong electromagnetic permeability and safe and reliable cooling water path.
Description
technical field [0001] The invention relates to an electromagnetic soft-contact continuous casting crystallizer, in particular to an electromagnetic soft-contact continuous casting crystallizer with slit and split flaps and external water cooling. Background technique [0002] Electromagnetic soft contact continuous casting is a new continuous casting technology. Its basic principle is to set an electromagnetic induction coil for alternating current outside the mold to excite the electromagnetic field. According to Faraday's law of electromagnetic induction, the time-varying electromagnetic field acts on molten steel and will The eddy current is induced on the surface of the liquid, and the interaction between the electromagnetic field and the eddy current will generate an electromagnetic pressure pointing to the interior of the slab, which offsets part of the static pressure of the molten steel, making the molten steel convex at the meniscus of the mold This widens the infl...
