Description
Technical field
The utility model belongs to continuous casting technology field, to particularly relate in continuous casting production process in ladle pouring molten steel to collector nozzle of ladle during tundish.
Background technology
In continuous casting production process; for reducing the secondary oxidation of molten steel, have employed whole process protection cast measure: molten steel ladle face to add in coverture → ladle stamp → ladle molten steel by long nozzle be poured into molten steel face in tundish → tundish add heat preserving agent → Metal in Tundish by whole immersion type water-gap pouring in crystallizer → crystallization in molten steel face add covering slag.When wherein pouring molten steel is to tundish in ladle, between collector nozzle of ladle and long nozzle, adopt the duplicate protection of seal washer and long water gap bowl part blowing argon gas.The material of seal washer is alumina silicate fibre, its shape is inverted cap and bottom has through hole, the internal diameter of seal washer is slightly larger than collector nozzle of ladle external diameter, and the external diameter of seal washer is slightly less than long nozzle internal diameter, and the height of seal washer is slightly less than long water gap bowl part height.
When using seal washer; seal washer be enclosed within collector nozzle of ladle bottom or put into long water gap bowl part, after ladle rotates to cast position, then operating long nozzle mechanism; top cover on long water gap bowl part and seal washer is lived collector nozzle of ladle;: on long nozzle in the process of top the phenomenons such as seal washer comes off, breakage often occur, seal washer of having to change at this method Problems existing; if deal with improperly; low liquid level will be caused to connect water, or affect molding casting effect, add the labour intensity of workman.Collector nozzle of ladle upper surface is provided with groove besides, and this groove matches with the boss of upper slide, and this structure is not easy to shaping and Mould Machining, and production cost is higher.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and a kind of collector nozzle of ladle with bowl seal circle is provided.
The technical solution of the utility model is: a kind of collector nozzle of ladle with bowl seal circle, and it comprises collector nozzle of ladle and bowl seal circle, and bowl seal circle is fixedly bonded on the conical shell of collector nozzle of ladle lower end.
Described collector nozzle of ladle is made up of collector nozzle of ladle body and box hat, collector nozzle of ladle body is cylindrical shell, the bottom of collector nozzle of ladle body is conical shell, the upper surface of collector nozzle of ladle body and lower surface adopt planar design, the cylindrical of collector nozzle of ladle body upper end is provided with a round platform, the cylindrical of collector nozzle of ladle body upper end and round platform upper surface adopt the transition of circular arc chamfering reducing, collector nozzle of ladle body is provided with central cast hole, box hat is wrapped on collector nozzle of ladle body, the upper surface of box hat is concordant with the upper surface of round platform, the conical shell bottom of collector nozzle of ladle body lower part is exposed outside the bottom of box hat.
The bottom of described bowl seal circle is provided with plug hole, and the internal diameter of plug hole is greater than the internal diameter of center plug hole on collector nozzle of ladle body, is provided with the stepped hole matched with collector nozzle of ladle body lower part conical shell bottom in the bottom of bowl seal circle.
The utility model compared with prior art has following features:
1, collector nozzle of ladle upper surface is designed to plane, shaping and easy to process, reduces production cost;
2, sealing ring is bowl structure, is fixedly bonded on collector nozzle of ladle, decreases the link of a molten steel air-breathing, meanwhile, avoids the breakage of sealing ring in the process of top on long nozzle, reaches good molding casting effect.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
