Abstract
The utility model provides a stopper rod type metering nozzle quick-pouring device, comprising a brick base; wherein, the external walls of the brick base are closely assorted with the inner walls of the outer package, an inner lining package is positioned at the bottom of the brick base, an upper water port is positioned on the inner lining package, and a zirconium bowl is arranged on the top of the inner lining package. The outer walls of the zirconium bowl are cylindrical and assort closely with the inner walls of the brick base, and the bottom of the zirconium bowl assorts closely with the zirconium core in the upper water port. A through hole is opened in the center of the zirconium bowl, the inner surface of the zirconium bowl is bent, a stopper rod is fixed on the zirconium bowl, a lower water port is positioned at the bottom of the upper water port, and a submerged long water port is arranged on lower part of the lower water port. The inner upper cavity of the long submerged water port is spherical-shaped with equal outer wall diameter and a cone at the bottom. The utility model has solved the problems in the prior art, realizes the control of the flow pouring by adjusting the matching gap between the bottom of the pouring stopper rod and the inner cavity of the zirconium bowl the during continuous casting production, so as to guarantee the casting machine works under a best speed and to improve the productivity and casting quality.
Description
Technical field
The utility model relates to smelting equipment, is a kind of Bar type fixed diameter water port fast exchanging pouring device in the continuous casting production in the iron and steel enterprise that is exclusively used in.
Background technology
The metering nozzle fast replacing device that in iron and steel enterprise, uses in the STEELMAKING PRODUCTION, though the improvement through 10 years left and right sides time has had bigger progress, but its deficiency is still comparatively outstanding: the molten steel speed of cast need adopt down the mouth of a river adjustment when continuous casting was produced, otherwise can not make casting machine be stabilized in work under the best pulling rate.And this adjustment can not realize multistage unlimited adjustment, only is applicable to the adjustment of a certain section flow, and when the mouth of a river is not as yet to service life instantly, then must destroy down the mouth of a river owing to need to adjust flow, and production cost is improved relatively.In addition, the metering nozzle fast replacing device of present various structures in use need cut off steel when stream in case accident occurs, can only squeeze into blind end by quick-changing mechanism and cut off steel stream at the cast passage, the method of this cut-out steel stream, if the filling pipe end of cast passage goes wrong, then be difficult to cut off steel stream, maybe need to take more complicated operations method, this also is that one of problem that needs solution is studied in this area always.
Summary of the invention
The purpose of this utility model provides a kind of Bar type fixed diameter water port fast exchanging pouring device, it mainly solves the deficiency that prior art exists, make the flow of its pour steel when continuous casting is produced can reach unlimited adjustment, and the purpose that when needs cut off steel stream, can reach quick and precisely, be convenient to operate.
The purpose of this utility model is achieved through the following technical solutions: Bar type fixed diameter water port fast exchanging pouring device, comprise the brick seat, brick seat outer wall closely cooperates with outer cylinder-packing inwall, cylinder-packing in install brick seat middle and lower part, interior cylinder-packing inwall is installed the mouth of a river, the zirconium bowl is installed in interior cylinder-packing upper end, zirconium bowl outer wall is that column and brick seat inwall closely cooperate, zirconium core in zirconium bowl bottom and the filling pipe end closely cooperates, and through hole is offered at zirconium bowl middle part, and zirconium bowl inwall is a conical camber, stopper is installed on zirconium bowl top, the mouth of a river is down installed in the filling pipe end bottom, and the immersion long nozzle is installed in bottom, the following mouth of a river, and immersion long nozzle top inner chamber is a dome shape, outer diameter equates, the bottom is a conical tube.The sphere place mounting spherical shape fiberglass packing of immersion long nozzle top inner chamber.Blind hole is offered at the stopper middle part.Aperture, zirconium bowl top is greater than the aperture, bottom, and inner chamber is cambered surface.Zirconium bowl outer wall bottom is provided with the plane, and the place, plane closely cooperates with interior cylinder-packing end face, and the plane tilts to be connected with zirconium bowl bottom.
Advantage of the present utility model is: solved problems of the prior art, realized when continuous casting is produced by adjusting the purpose that the gap of matching with zirconium bowl inner chamber the stopper bottom reaches control cast flow, having guaranteed that casting machine can be stabilized under the best pulling rate carries out work, has improved production efficiency and casting quality.And when needs cut off steel stream, can accomplish quick and precisely errorless, any quality problems and production accident can not appear, and, avoided air to enter in the molten steel owing to the sealing condition that has improved between the immersion long nozzle and the following mouth of a river, further improved the quality of cast product etc.
