Description
Technical field
The utility model relates to metallurgy industry equipment technical field, refers more particularly to anti-air-breathing slide gate nozzle for a kind of continuous casting hydraulic model.
Background technology
Flowing of molten steel in metallurgical process container is very complicated, laboratory often adopts hydraulic model to test to study flowing of the interior molten steel of container, according to the principle of similitude, the physical quantity under physical condition is similarly simulated in hydraulic model, studied flowing of the interior molten steel of metallurgical process container.
Slide gate nozzle is during continuous casting is produced, and is arranged on ladle and tundish bottom to realize the device that regulates molten steel flow.Its primary structure comprises: upper fixed sliding plate, Sliding partitions, lower fixed sliding plate, 5 parts of slide gate nozzle casing and hydraulic jack, wherein go up fixed sliding plate and connect metallurgical tank outlet, lower fixed sliding plate connects molten steel protection tube, and (refractory material is made, arrive next metallurgical tank for delivery of molten steel, play the tube connector of the effect of isolated air), between upper and lower fixed sliding plate, Sliding partitions is housed, three slide plates overlay in slide gate nozzle casing, Sliding partitions is connected with hydraulic jack, under hydraulic oil cylinder driving, horizontally slip, thereby make itself and the upper and lower fixed sliding plate mouth of a river produce relative dislocation and realize adjusting steel stream.
The theoretical foundation of metallurgical fluid water Mechanical Model Test is the principle of similitude, meet the principle of similitude, first will guarantee model and metallurgical tank prototype geometric similarity.Slide gate nozzle is in casting process, and ladle is to tundish, tundish to molten steel flow control device conventional between crystallizer.In hydraulic model test, to the simulation of slide plate flow control device, there are two kinds of modes: 1, adopt the metal gate valve simulation slide gate nozzle with bore, metal gate valve is by regulating the opening degree of valve plate in valve to realize the adjusting of flow, because its degree of regulation is high, air-tightness is good, buys and the advantage such as easy for installation, has good applicability for the water model of simple piping flow adjusting.2, install and simulate slide gate nozzle with the mode of the scalable plate in aperture in exit.Be about to have the plate in same aperture, vertically be inserted on the cross section of export pipeline, by push-and-pull plate, adjust the registration at itself and the mouth of a river and control flow, because its flow control mode is identical with slide gate nozzle, can accurately simulate flowing of the interior molten steel of the mouth of a river and pipeline.But there is following problem in method at present:
(1) the flow control mode of metal gate valve is different from slide plate, does not meet geometric similarity requirement in hydraulic model.Because the mode of its overcurrent and actual slide gate nozzle are distinguished to some extent, actual slide gate nozzle is that the segment fluid flow overlapping between fixed sliding plate hole and Sliding partitions hole can pass through.And metal gate valve is by regulating the opening degree between flashboard and tube wall to carry out adjust flux.In the time of the flow field of studying in the little volume receptacles such as long nozzle, the SEN mouth of a river and crystallizer, the difference of overcurrent mode, can have a huge impact by stream field.
(2) poor with the flow control mode sealing of the flexible plate in aperture, in process of the test, often cause the suction of gas, and flow control accuracy is low, operation easier is high, has affected the accuracy of result of the test.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency to above-mentioned existence just, provide a kind of continuous casting hydraulic model to prevent air-breathing slide gate nozzle, this slide gate nozzle adopts screw rod to rotarily drive slide plate slides, by regulating the registration between upper lower skateboard to carry out adjust flux, meet the similitude of overcurrent mode and actual slide gate nozzle, guarantee the accurate control of Flow-rate adjustment, whole Sliding partitions is sealed in the casing of upper bottom plate formation simultaneously, avoid the suction of air in process of the test, improve the accuracy of test.
The utility model solves the technical scheme that its technical problem adopts:
Anti-air-breathing slide gate nozzle for continuous casting hydraulic model, it is characterized in that: include fixed sliding plate, Sliding partitions and lower fixed sliding plate, wherein, in upper fixed sliding plate, there is water inlet, water inlet raises up and extends into tubulose, on lower fixed sliding plate correspondence position, there is delivery port, delivery port extends into tubulose to lower convexity, water inlet is identical with delivery port caliber size, and upper and lower fixed sliding plate stacks, intake-outlet forms coaxitron structure, and by upper and lower fixed sliding plate sealing, its joint portion forms the slip storehouse of Sliding partitions, Sliding partitions is placed in slip storehouse, on Sliding partitions, be provided with the through hole identical with delivery port caliber with water inlet, and at Sliding partitions during in extreme position, through hole and intake-outlet coincide.
In such scheme, in described Sliding partitions, be provided with internal thread, and screw rod is being installed, one section of screw rod extends slip storehouse, and the end extending at screw rod is provided with handle.
In such scheme, described screw rod extends slip storehouse from lower fixed sliding plate, and in junction, sealing ring is housed, and sealing ring plays the effect in standing screw and sealing screw rod and lower fixed sliding plate perforate gap; Sealing ring includes setscrew nut, gasket seal and fastening nut, setscrew nut is metal material, left end and lower fixed sliding plate tapping are enclosed within on screw thread, play the effect of positioning screw, setscrew nut is also provided with external screw thread, its outside with fastening nut with being threaded, fastening nut wraps setscrew nut from outsourcing, and between gap location is provided with gasket seal, while tightening up fastening nut, can abut against between setscrew nut and screw rod by crush seal pad, play seal clearance, prevent the effect that gas enters.
