Abstract
The utility model discloses a submersed nozzle with a novel structure. The submersed nozzle comprises bodies 1 and slag lines 2; the surfaces of inner holes of the bodies 1 and the slag lines 2 are respectively covered with inner linings 3 made of calcium zirconate material; and a medium binding layer 4 made of alumina-carbon material is arranged between each inner lining 3 and each slag line 2. The submersed nozzle is characterized in that the inner linings made of calcium zirconate material are added on the basis of the present submersed nozzle, so that the scouring resistant effect is achieved, the scouring to the inner holes is alleviated, and the service life of the nozzle is prolonged. The slag lines are made of zirconia-carbon material of which the thermal expansion coefficient is largely different from that of calcium zirconate material, so that the probability of cracking of the nozzle is high; however, in the utility model, the medium binding layer made of alumina-carbon material is added between each inner lining and each slag line, and the thermal expansion coefficient thereof is better matched with that of the slag lines and the inner linings, so that the probability of cracking of the nozzle is low.
Description
Technical field
The utility model relates to a kind of immersion nozzle for continuously casting.
Background technology
Submersed nozzle is the functional refractory of most critical during continuous casting is produced, it is located between continuous casting tundish and the crystallizer, be used for molten steel is transported to crystallizer, except prevent that molten steel from reoxidizing and stable supply molten steel, in crystallizer inner control molten steel flow pattern is the important function that submersed nozzle rises, and its result of use directly influences casting efficiency and billet quality.The submersed nozzle that uses in the casting process is generally the aluminium carbonaceous material now, because molten steel impulsive force when toppling over of fusion is bigger, make the decarburization easily in use of this material, cause endoporus to wash away seriously, thereby limited the performance and the raising of continuous casting line efficient, strengthened production cost.
Summary of the invention
Problem to be solved in the utility model provides that a kind of endoporus anti-ly washes away, the submersed nozzle of long service life.
The submersed nozzle of a kind of new structure of the utility model comprises body 1 and slag line 2, and at surface coverage one deck liner 3 of body 1 and slag line 2 endoporus, material is that zirconic acid is calcareous; Also have one deck middle close binder 4 between liner 3 and slag line 2, material is the aluminium carbonaceous.
Characteristics of the present utility model are: increased one deck liner on the basis of existing submersed nozzle, its material is the calcium zirconate material, has anti-effect of washing away, and has alleviated endoporus and has washed away, and has prolonged the service life at the mouth of a river.Because the material of slag line is the zirconium carbonaceous material, differ bigger with the thermal coefficient of expansion of calcium zirconate material, cause the mouth of a river easy to crack, so between liner and slag line, add a middle close binder, adopt the aluminium carbonaceous material, its thermal coefficient of expansion and slag line, liner thermal coefficient of expansion mate more, make the mouth of a river not easy to crack.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the structural representation of the submersed nozzle of a kind of new structure of the utility model,
Fig. 2 is existing submersed nozzle structural representation.
The specific embodiment
The submersed nozzle of a kind of new structure of the utility model comprises body 1 and slag line 2, and at surface coverage one deck liner 3 of body 1 and slag line 2 endoporus, material is that zirconic acid is calcareous; Also have one deck middle close binder 4 between liner 3 and slag line 2, material is the aluminium carbonaceous.Wherein, the thickness of slag line 2 is 10-12mm, and the thickness of liner 3 is 3-8mm, and the thickness of middle close binder 4 is 10-15mm.
Characteristics of the present utility model are: increased one deck liner on the basis of existing submersed nozzle, its material is the calcium zirconate material, has the effect of resistance to erosion, has alleviated endoporus and has washed away, and has prolonged the service life at the mouth of a river. Because the material of slag line is the zirconium carbonaceous material, differ bigger with the thermal coefficient of expansion of calcium zirconate material, cause the mouth of a river easy to crack, so between liner and slag line, add a middle close binder, adopt alumina graphite material, its thermal coefficient of expansion and slag line, liner thermal coefficient of expansion mate more, make the mouth of a river not easy to crack.
