Description
Technical field:
The utility model relates to the amorphous band manufacturing technology field in the metal smelt, and particularly a kind of production amorphous band is used tundish.
Background technology:
In the system band process of amorphous band; Molten steel in the smelting furnace gets into tundish through guiding device; Through the volume control device in the tundish, the control molten steel gets into spray band bag with certain flow then, thereby guarantees that molten steel liquid level is at certain altitude in the spray band bag; Molten steel in the spray band bag drops on the atwirl chill roll after flowing out through nozzle, behind chilling, forms amorphous band on the chill roll surface.At present in actual production process, when high-temperature molten steel when guiding device gets into tundish, a large amount of molten steel are at the bottom of the inlet beam directly impacts crucible, the phenomenon that long-term use possibly cause crucible bottom to occur running through has reduced service life of crucible.Field trash is more in the molten steel, can cause spray nozzle clogging, influences nozzle place molten steel flow, influences strip density or causes the band bifurcated, influences strip quality.So, be to solve the field trash plug nozzle in the molten steel, influence the problem of the discharge stability of nozzle place molten steel, press for occur a kind of simple in structure, easy to use, can cleaning molten steel and effectively reduce the tundish of beam molten steel to the crucible bottom impact.
Summary of the invention:
The purpose of the utility model is to overcome the shortcoming that exists in the prior art, provides simple in structure, and is easy to use, effectively cleaning molten steel and reduce the tundish that the beam molten steel impacts crucible bottom.
To achieve these goals, the utility model provides a kind of production amorphous band to use tundish, comprises housing, crucible and heater; Wherein, said crucible and heater are positioned at enclosure interior, and said heater is looped around the outside of crucible; Be provided with heat-insulation layer between said heater and the said housing; The top of said housing is provided with inlet, further is provided with buffer stopper under the said inlet, and said buffer stopper is positioned at the bottom of said crucible.
Further be provided with funnel on the said inlet; Said housing is provided with stopper; Said stopper runs through housing and extends to the bottom of crucible; The bottom of said housing is provided with porous plug and housing liquid outlet, and the bottom of said crucible is provided with liquid outlet, and said housing liquid outlet is connected with liquid outlet on the said crucible.
Said heater is a U type elema heater,
But said heater fast online replacement.
Said porous plug is the diffusion-type porous plug, and its material is a chrome corundum.
Said porous plug is through housing bottom and crucible bottom, and said porous plug is used for charging into argon gas to crucible inside, plugs together between said funnel and the said inlet to be connected, and said inlet is positioned at the top of said crucible.
The advantage of the utility model is, and is simple in structure, easy to use, and its major advantage is for making inclusion floating in the molten steel, can effectively reducing the beam molten steel crucible bottom is impacted and the elema heater fast changeable.The tundish of the utility model is provided with buffer stopper in crucible bottom, when molten steel injects crucible; Fall earlier on the buffer stopper, flow to crucible bottom from buffer stopper again, molten steel speed has obtained very big buffering; Reduced of the impact of beam molten steel, effectively protected at the bottom of the crucible crucible bottom.
The tundish of the utility model in addition; In crucible bottom the porous plug that logical argon gas is used is installed, porous plug is vertical setting with respect to crucible bottom, is blown into small Argon Bubble through porous plug; Can on this position, form the air curtain partition wall; Both can change the flow performance of tundish fluid, air curtain can play buffer action to field trash again, stops field trash to flow to the fluid oral-lateral.Big or small field trash with the minute bubbles collision will be taken on the molten steel face by bubble.Therefore, the inclusion floating that the crucible argon bottom-blowing helps in the molten steel is separated, and improves the removal ability that is mingled with of tundish.
The tundish of the utility model is provided with heater between housing and crucible, heater can prevent effectively that the molten steel in the crucible from cooling off fast, and, but the heater fast online replacement.
The tundish of the utility model; The external shell that inlet is corresponding is provided with funnel; The effect of funnel is to admit the molten steel from the smelting furnace, thereby avoids causing molten steel to be not easy to get into the phenomenon of tundish because inlet is less, has reduced operation easier.
