Description
Technical field
The present invention relates to the conticaster system, particularly the two cold water spray devices used of a kind of billet continuous casting.
Background technology
Continuous casting production is the final step of steel making working procedure, also is a most important step.Square billet two cold water spray devices are one of emphasis equipment of conticaster, are the keys that guarantees continuous casting billet appearance and size and obtain good internal soundness.In two cold houses, just gone out the inner ot-yet-hardened of high temperature strand of crystallizer, need continue strand is cooled off in two cold-zones, collector pipe is passed through in cooling to strand in two cold houses, tube connector, and nozzles etc. spray to casting billet surface with water, heat is taken away, reached the purpose of cooling strand.
Environment very severe in two cold houses, the vibration that has high temperature heat radiation, heavily loaded stress alternation to cause, the erosion of high moist steam, water, iron scale etc., and the space is airtight relatively, narrow and small, the maintenance of equipment, and it is limited to change the operating space.Two cold water spray devices are because heat radiation distortion, and iron scale is burnt, stopped up, reasons such as bleed-out burn and normal consumption, and it is safeguarded, dismounting, frequency of changing want high many than other equipment of conticaster.Therefore the dismounting of two cold water spray devices, replacing be trouble, time-consuming bothersome very, just seems particularly important so design a kind of billet continuous casting spray equipment simple in structure, quick detachable, fast changeable.
The structural representation of existing billet continuous casting two cold water spray devices as shown in Figure 1, 2, mostly adopt collecting ring that cooling water is dispensed to collector pipe, 4 weeks of strand 6 are adopted 4 collector pipes, collector pipe is arranged in inner arc side, outer arc side, the left and right sides of conticaster, collector pipe is connected water pipe 3 and adopts screw thread to link to each other with nozzle, perhaps be fabricated integrally in together; Nozzle connects water pipe and adopts nozzle 4 that secondary cooling water is sprayed to cool off strand again.The shortcoming that existing equipment exists:
1) complex structure, two cold each district all need collecting ring, retainer ring and 4 collector pipes, on each root collector pipe many arms are arranged, and it forms the structure more complicated;
2) collector pipe is monoblock type, there are many nozzles to connect water pipe 3 on the collector pipe, it is to be welded to connect that nozzle connects between water pipe 3 and the collector pipe, bigger distortion is arranged or have nozzle to connect water pipe 3 damages in case nozzle connects water pipe 3, just need whole collector pipe all disassembled maintenance or change maintainability and economical all bad;
3) because the version complexity, collector pipe is monoblock type, and the collector pipe of in a section a certain or certain collector pipe damages and just production caused great influence, even need stop to water failure flow, and recover failure flow needs time of length and very difficult.
Summary of the invention
The two cold water spray devices that provide a kind of billet continuous casting simple in structure, quick detachable, fast changeable to use at the technical problem that exists in the above-mentioned prior art are provided technical problem to be solved by this invention.
The technical solution adopted in the present invention is: the two cold water spray devices that billet continuous casting is used, it is characterized in that it comprises inner arc collector pipe, outer arc collector pipe, nozzle tube connector, nozzle, inner arc collector pipe, outer arc collector pipe are fixed on the fixed mount, be equipped with the water inlet delivery port at inside and outside arc collector pipe, be provided with the nozzle tube connector that is mutually the right angle at the delivery port place of inside and outside arc collector pipe, each nozzle tube connector is symmetrically distributed in around the strand, and described nozzle tube connector is connected with nozzle.
By technique scheme, described nozzle tube connector adopts plug-in to be connected with inner arc collector pipe and outer arc collector pipe.
By technique scheme, described inner arc collector pipe and outer arc collector pipe are respectively 1, and correspondence is arranged on the cornerwise both sides of strand.
By technique scheme, described nozzle tube connector and inner arc collector pipe and outer arc collector pipe seal arrangement, and fix by bearing pin.
By technique scheme, be provided with protective cover in the junction of inside and outside arc collector pipe and nozzle tube connector.
By technique scheme, described protective cover is U-shaped.
By technique scheme, described inside and outside arc collector pipe is square collector pipe, sets out the mouth of a river respectively at the adjacent surface of inside and outside arc collector pipe.
The obtained beneficial effect of the present invention is:
1, the present invention fixes without collecting ring with respect to prior art, just arranges that at the diagonal of strand 2 collector pipes are inner arc collector pipe, outer arc collector pipe, so not only simplify the structure, and handled easily, and reduced equipment, saving cost;
2, adopt between nozzle tube connector and the inside and outside arc collector pipe that to flexibly connect be that plug-in is connected, be rigidly connected with respect to monoblock type of the prior art, the present invention can be according to the fact damaged situation, carry out local replacing, dismounting, it is convenient to realize changing fast and changing, can save a large amount of repair times, further improve the operating rate of conticaster.；
3, the junction of nozzle tube connector and inside and outside arc collector pipe arranges protective cover, and it is dead with the two weldering to prevent from occurring in the production process bleed-out, causes and can't dismantle.
