Abstract
The utility model provides a condenser and immersion type water gap, which is characterized in that the condenser and immersion type water gap is arranged between a crystallizer and a tundish, and the condenser and immersion type water gap can act functions of a molten steel path from the tundish to the crystallizer. The condenser and immersion type water gap is composed of a high temperature resistance immersion type water gap (3) and a water-cooling device. The water-cooling device can be a spiral tube type and can be a sleeve cylinder type, and the high temperature resistance immersion type water gap (3) can be made of ceramic materials and can be made of composite materials of metal and ceramics. The utility model has the advantages that the condenser and immersion type water gap can reduce temperature of the molten steel which enters the tundish or can cast moulds or other metal liquids; crystallite can be refined; segregation can be reduced, and looseness can be reduced.
Description
The utility model provides a kind of remodeling or substituting product of casting process submersed nozzle, also can be used for casting, metal solidification process.
Existing submersed nozzle can provide protection to the molten steel from the tundish to the crystallizer, prevents that gas from entering molten steel, thereby guarantees not make the air pollution molten steel in this process of casting.
The basic demand of high-quality steel is that steel is pure, uniform ingredients, grain refinement.So the metallargist takes all measures to realize above-mentioned three requirements.
In casting process, from improving the quality of continuous casting billet, wish that the cast temperature with molten steel is controlled near the liquidus curve, reducing segregation, the shrinkage cavity and loose that casting process produces, and in casting cycle, make grain refinement as far as possible.Existing submersed nozzle has the function that prevents the air pollution molten steel, but does not have at casting process condensation molten steel, thereby reduces segregation, shrinkage cavity and loose, and makes the function of grain refinement in casting cycle as far as possible.
At crystal grain thinning, the groundwork that reduces loose aspect had in recent years:
1, the liquid core is depressed.As: YAMANAKA, The slab casting with liquid corereduction, Ironmaking and steelmaking, 1999, vol.26, No6,457-462 does brave, Chen Dongliang, the numerical simulation that sheet blank continuous casting liquid core is depressed process, iron and steel, 1999, vol.34, No6,27-31.
2, zerolling.As: Li Xiaoyu, zerolling technology and application thereof, steel rolling, in June, 1998,13-18.For the space to crystallizer from middle water containing opening, Shang Weijian is used to control the grain size of molten steel and solidifies loose.
The object of the present invention is to provide a kind of condensation type submersed nozzle, the space of utilization from middle water-coating port to crystallizer, make original submersed nozzle become an existing original air-breathing function that prevents, again can be by being looped around the water quench molten steel on the crystallizer or in the cooling water pipe, control molten steel cast temperature, reduce segregation, shrinkage cavity and loose that casting process produces, the function of crystal grain thinning.
Formation of the present utility model: the utility model has the resistant to elevated temperatures intrusive mood mouth of a river (3) and water cooling plant to form, and its water cooling plant can be a helix tube type, also can be telescopic; The resistant to elevated temperatures intrusive mood mouth of a river can be a ceramic material, also can be metal and ceramic composite.The utility model is placed between crystallizer and the tundish, plays the molten steel channel effect of tundish to crystallizer.
Advantage of the present utility model is: can reduce the temperature that enters tundish or casting die molten steel or other molten metal, crystal grain thinning reduces segregation, reduces loose.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a helix tube type condensation type submersed nozzle schematic diagram of the present utility model, and wherein (3) are the resistant to elevated temperatures intrusive mood mouth of a river, and (4) are helix tube, and (1) is that water inlet, (2) on the helix tube are the delivery port on the spiral.
Fig. 2 is a telescopic condensation type submersed nozzle schematic diagram of the present utility model, and wherein (3) are the resistant to elevated temperatures intrusive mood mouth of a river, and (7) are sleeve, and (5) are that water inlet, (6) are delivery port.
Embodiment: when Zhengzhou Yongtong Special Steel Co., Ltd.'s two stream 130mm billet caster integral bearing bearing steels, compare test, first-class therein installation condensation type submersed nozzle, water inlet pressure is 0.5MPa, 50 ℃ of leaving water temperatures, the first-class billet surface of cooling is a kermesinus, and another stream is for red.Cut the presentation of results of analysis open along the square billet center line, the first-class equiax crystal amount of cooling increases by 7%, no shrinkage cavity, segregation, loose obviously minimizing.
Claims (3)
1, a kind of condensation type submersed nozzle, it is characterized in that being placed between crystallizer and the tundish, play the molten steel channel effect of tundish to crystallizer, be made up of the resistant to elevated temperatures intrusive mood mouth of a river (3) and water cooling plant, its water cooling plant is a helix tube type or telescopic; The resistant to elevated temperatures intrusive mood mouth of a river is the composite of ceramic material or metal and pottery.
2, condensation type submersed nozzle according to claim 1 is characterized in that water cooling plant is a helix tube type, and helix tube (4) has water inlet (1), delivery port (2).
3, condensation type submersed nozzle according to claim 1 is characterized in that water cooling plant is telescopic, and by sleeve (7), water inlet (5), delivery port (6) are formed.
