Abstract
The utility model provides a novel thin immersion nozzle for continuous slab casting, should be thin continuous slab casting for immersion nozzle the immersion nozzle neck directly period number put and has set up one section aluminium foil composite bed. Toast and when using, the aluminium foil composite bed can prevent effectively that moisture content in the ramming mass from to thin for the continuous slab casting destruction on the anti -oxidation glaze layer of immersion nozzle neck, effectively having reduced the phenomenon of thin immersion nozzle neck oxidation for the continuous slab casting, has solved the thin perforation that immersion nozzle caused for the continuous slab casting, fracture problem because of the neck oxidation, has stabilized thin for continuous slab casting immersion nozzle's product quality.
Description
Technical field
The utility model belongs to Sheet-bar Continuous Casting Technique field, relates generally to a kind of Novel sheet billet continuous casting submersed nozzle.
Background technology
Sheet blank continuous casting is the comparatively advanced near net shape continuous casting technique of present stage steel industry.Submerged nozzle for continuous casting of thin slabs is one of core technology of sheet blank continuous casting, and the service life and the quality stability that improve submerged nozzle for continuous casting of thin slabs improve the key link of tundish casting sequence.Along with the increase of casting sequence, the perforation of submerged nozzle for continuous casting of thin slabs neck, phenomenon of rupture frequently, have had a strong impact on the normal production of thin-slab caster.
Utility model content
The purpose of this utility model is the above-mentioned technical problem solving prior art existence, designs a kind of Novel sheet billet continuous casting submersed nozzle.
The utility model is achieved through the following technical solutions: described Novel sheet billet continuous casting submersed nozzle arranges one section of aluminium foil composite bed in the neck straight section position of submersed nozzle.
The beneficial effects of the utility model are embodied in, arranging aluminium foil composite bed can effectively prevent the moisture content in ramming mass to the destruction of the anti-oxidation glaze layer of submerged nozzle for continuous casting of thin slabs neck, effectively reduce the phenomenon of neck oxidation in submerged nozzle for continuous casting of thin slabs baking and use procedure, solve submerged nozzle for continuous casting of thin slabs because neck oxidation and cause perforation, breakage problem, stabilize the product quality of submerged nozzle for continuous casting of thin slabs.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Wherein, 1, submerged nozzle for continuous casting of thin slabs, 2, aluminium foil composite bed.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
The utility model provides a kind of Novel sheet billet continuous casting submersed nozzle, as shown in Figure 1, comprises submerged nozzle for continuous casting of thin slabs (1) and aluminium foil composite bed (2).
Further, above-described a kind of Novel sheet billet continuous casting submersed nozzle, described aluminium foil composite bed (2) is arranged on the neck straight section position of submerged nozzle for continuous casting of thin slabs (1).
The beneficial effects of the utility model are embodied in, arranging aluminium foil composite bed (2) can effectively prevent the moisture content in ramming mass to the destruction of the anti-oxidation glaze layer of submerged nozzle for continuous casting of thin slabs (1) neck, effectively reduce the phenomenon of submerged nozzle for continuous casting of thin slabs (1) neck oxidation in baking and use procedure, solve because neck oxidation and cause perforation, breakage problem, stabilize the product quality of submerged nozzle for continuous casting of thin slabs (1).
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of being formed, all drop within the claimed scope of the utility model.
Claims (1)
