Abstract
The utility model relates to an improved molten steel continuous casting water opening sealing device which is characterized in that a circular groove on the upper end of a large or medium long water opening and a circular flange at the lower end of the large or medium water opening are spliced to form a parent-child connection; a fusible metal sealing ring is arranged at the joint; during casting, the fusible metal sealing ring contacts the high temperature molten steel, fused and left in the groove at the join to thoroughly stop the air from entering, so as to prevent the molten steel from secondary oxidation and ensure the quality of continuous casting steel billets.
Description
Technical field
The utility model relates to continuous casting of molten steel equipment, promptly a kind of continous casting sprue sealing device.
Background technology
Molten steel will be avoided contacting with air in casting process, in case secondary oxidation makes gas and inclusion content rising in the steel, influences product quality.In the casting process, the molten steel flow at high speed, big bag or Zhong Bao with wrap greatly or middle bag long nozzle seam crossing can produce negative pressure, make air enter long nozzle and contact with molten steel, cause the secondary oxidation of molten steel.Therefore, the seal protection to continous casting sprue just becomes key problem in technology.At present, to the general grafting argon envelope that adopts between continuous casting Da Bao and the big bag long nozzle, promptly on long nozzle, establish an Argon pipe import, spray into argon gas during continuous casting and intercept air, but owing to the argon gas that sprays into can not be consistent at mouth of a river seam crossing pressure, so argon envelope effect is not good enough; And adopting the pad envelope of pegging graft at Zhong Bao and middle bag long nozzle seam crossing, effect is more undesirable, is difficult to stop air to be inhaled into molten steel.
Summary of the invention
The utility model will provide a kind of practical and effective sealing device exactly, flows through in casting process with thorough solution molten steel and wraps greatly, and the air-breathing problem of middle water-coating port seam crossing is guaranteed the continuous casting steel billet quality.
For this reason and the design the continous casting sprue sealing device, form with the seal of big bag or middle bag long nozzle and junction thereof by big bag or middle water-coating port, the annular groove that on big bag or middle bag long nozzle, has notch to make progress, and there is the annular lip of inserting in big bag or long mouthful of top ring connected in star of middle bag bag or middle water-coating port lower end greatly, the formation mother-son mouth connects, fusible metal or alloy material sealing ring are arranged between connection place annular groove and the annular lip, in the casting process, sealing ring contact high-temperature molten steel is molten state, and rests on mouth of a river seam crossing sealing mother-son mouth and thoroughly intercept air.For fusible metal or the alloy sealing ring that prevents molten state overflows annular groove, the outer rim of bag or middle bag long nozzle top ring connected in star can be higher than inner edge greatly.
The utility model continous casting sprue sealing device structure is scientific and reasonable, and the meltable sealing ring of mother-son mouth connection place can effectively stop air, stops secondary oxidation of steel.
Description of drawings
Fig. 1 is the utility model continous casting sprue sealing device schematic diagram.
The specific embodiment
As shown in Figure 1, annular lip 5 and being made up of fusible metal such as tin, aluminium, zinc or its alloy material sealing ring 3 therebetween in the annular groove 2 inserted in annular groove 2 that the continous casting sprue sealing device is made progress by big bag or middle bag long nozzle 1 upper end notch and big bag or middle water-coating port 7 lower ends, in the casting process, meltable sealing ring 3 is molten state, and stay the mother-son mouth connection place, seal seam, intercept air.The outer rim 6 of annular groove 2 is higher than inner edge 4 on big bag or the middle bag long nozzle 1, overflows to stop molten state fusible metal encapsulant.
Claims (2)
1, the continous casting sprue sealing device, form with the seal of big bag or middle bag long nozzle and junction thereof by big bag or middle water-coating port, it is characterized in that the annular groove (2) that said big bag or middle bag long nozzle (1) upper end has notch to make progress, there is the annular lip of inserting in big bag or middle bag long nozzle (1) the top ring connected in star (2) (5) said big bag or middle water-coating port (7) lower end, the formation mother-son mouth connects, fusible metal or alloy material sealing ring (3) are arranged between annular groove (2) and the annular lip (5), in the casting process, sealing ring (3) is molten state, the sealing mother-son mouth.
2, continous casting sprue sealing device according to claim 1 is characterized in that the outer rim (6) of said big bag or middle bag long nozzle (1) top ring connected in star (2) is higher than inner edge (4).
