Abstract
The utility model discloses a long-service life steel ladle drain hole, comprising a steel shell, wherein a fireproof liner is moulded by casting on the inner wall of the steel shell; a steel passing hole is formed at the middle of the fireproof liner; an inwards recessed positioning hole is formed on the outer wall of the steel shell; and the positioning hole is a blind hole so that the fireproof liner is closely and integrally combined with the inner wall of the steel shell. The long-service life steel ladle drain hole is characterized in that the steel shell is well fixed with the fireproof liner without falling, and easy to mount, position and use; and therefore, the phenomenon of steel liquid leakage is reduced, the smelting danger coefficient of steel materials is reduced and the practical service life of the product is prolonged.
Description
Technical field
The utility model relates to metallurgical technology field steel-making industry, refers to particularly a kind of high life collector nozzle of ladle.
Background technology
Slide gate nozzle in 1964, after Germany is used successfully, receives steel mill greatly and welcomes, and steel mill imitates and applies one after another all over the world.Slide gate nozzle is mainly used in the steel flow control system of ladle and tundish, is one of chief component of non-oxidation continuous casting protection system.Slide gate mechanism is the passage that molten steel enters tundish; work to control the steel temperature, regulate steel stream; because controllability is good, safe, developed rapidly; steel ladle sliding water gap mainly is comprised of filling pipe end, sliding plate brick and the lower mouth of a river; collector nozzle of ladle is the passage of stream steel; and be connected with large bag long nozzle, guarantee protective casting, prevent the secondary oxidation of molten steel.Collector nozzle of ladle, as the critical function parts in the slide gate mechanism system, requires its fire resistance and reliable in mechanical performance, and synchronizes and use with slide plate.Along with the development of refinery practice, the production technology of collector nozzle of ladle is also in continuous development.The production technology of collector nozzle of ladle by original die casting moulding after the demoulding, be inserted in box hat, develop into gradually directly direct moulding by casting on box hat, this molding mode technique is improving production efficiency greatly, but exist dry rear inner castable and the apertured defect of box hat, cause molten steel leakage, increased steel and smelted danger coefficient, and box hat and the castable phenomenon that easily shells.
Summary of the invention
The purpose of this utility model will overcome above-mentioned deficiency exactly, and a kind of high life collector nozzle of ladle is provided.
For achieving the above object, the high life collector nozzle of ladle that the utility model is designed, comprise box hat, described box hat inwall moulding by casting has fire-resistant inner bag, in the middle of described fire-resistant inner bag, be provided with the steel hole, it is characterized in that: on described box hat outer wall, be provided with the locating hole of depression inwards, described locating hole is blind hole, thereby fire-resistant inner bag and box hat inwall are closely as one.
Further, described locating hole is uniformly distributed on the box hat outer wall.
Further, described locating hole is arranged on the same cross section in box hat outer wall middle part, and interval 120o distributes.
Again further, the depth bounds of described locating hole is 3 ~ 5mm.
The utility model has the advantage of:
1, box hat and fire-resistant inner bag are fixed well, and can not shell, and are easy to install, locate, use.
2, box hat and fire-resistant inner bag are seamless, reduce molten steel leakage, reduce steel and smelt danger coefficient.
3, the box hat generation melting of collector nozzle of ladle, generally caused by molten steel leakage, adopts the present invention, when reducing molten steel leakage, can increase the service life of product.
When 4, improving service life, also can reduce production costs.
The accompanying drawing explanation
Fig. 1 the utility model high life collector nozzle of ladle structural representation.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
In figure: box hat 1, fire-resistant inner bag 2, cross steel hole 3, locating hole 4.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
High life shown in figure takes off collector nozzle of ladle, comprise box hat 1, in box hat 1, be cast with fire-resistant inner bag 2, in the middle of fire-resistant inner bag 2, be provided with steel hole 3, depression locating hole 4 is laid every 120o in box hat 1 middle part, thereby fire-resistant inner bag 2 is closely as one with box hat 1 inwall, or lays corresponding hole and be uniformly distributed according to service condition, locating hole 4 does not run through, and depth bounds is at 3-5mm.Fire-resistant inner bag 2 casts directly in box hat 1, and natural Health preservation 24 hours, carry out drying, and baking temperature is in 200 ℃, and insulation, more than 10 hours, is arranged on collector nozzle of ladle on sled mechanism and uses during use, after reaching lower line standard, and the dismounting of rolling off the production line.
