Abstract
The utility model provides a stopper rod type metering nozzle quick-pouring device, comprising a brick base; an upper water port is positioned in a cavity below the brick base, a water port core is arranged within the upper water port, and the upper water port is integrated with the water port core as one piece; a prolonged conical water port is arranged at the upper part of the cavity, a zirconium bowl is positioned at the upper cavity of the prolonged conical water port and a stopper rod is positioned at the upper part of the zirconium bowl; a lower water port is arranged at the bottom of the upper water port, and an immersion type prolonged water port is arranged at the bottom of the lower water port. 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 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's STEELMAKING PRODUCTION, uses, 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, and brick seat lower lumen is installed the mouth of a river, and mouth of a river core is installed in the filling pipe end, filling pipe end and mouth of a river core are one, brick seat inner chamber top is installed pyramid type and is added long nozzle, and pyramid type adds long nozzle inner chamber top the zirconium bowl is installed, and stopper is installed on zirconium bowl top, the mouth of a river is down installed in the filling pipe end bottom, and bottom, the following mouth of a river is installed immersion and added long nozzle.It is that the sphere outer wall is a column that immersion adds long nozzle top inner chamber, and the bottom is the taper pipe.Immersion adds the sphere inwall mounting spherical fiberglass packing on long nozzle top.Pyramid type adds long nozzle top inner chamber and is coniform, and lower lumen is cylindric, at cylindric inner chamber the zirconium core is installed.Pyramid type adds long nozzle upper cone shape inner chamber the zirconium bowl is installed, and it is coniform that the inner chamber top of zirconium bowl is open type, and the bottom is cylindric.Blind hole is offered at the stopper middle part, offers positioning through hole on the blind pore wall.
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.
