Abstract
The utility model relates to a continuous-cast tundish-nozzle on-line baking device composed of a furnace body, an ejector smoke-exhausting pipe, a compressed air pipe, and a flux-adjusting valve, wherein, the middle at the top of the furnace body is provided with a round hole for a continuous-cast tundish being inserted, the circumference of the round hole is provided with a sealing device; the lower part of the furnace body is provided with a smoke outlet communicated with the ejector smoke-exhausting pipe, the compressed air pipe is installed on the ejector smoke-exhausting pipe, and the flux-adjusting valve is installed on the compressed air pipe. A silencer is arranged at the end of the ejector smoke-exhausting pipe. The continuous-cast tundish-nozzle on-line baking device has the advantages that the baking speed is fast, the baking temperature is high, the temperature evenness is good, and the baking speed can be adjusted. The utilization ratio of the heat-energy can be improved by making use of flames achieving heat-exchange with the tundish lining to bake the nozzle.
Description
Technical field
The utility model relates to a kind of middle water containing opening apparatus for baking of field of steel-making, the online apparatus for baking of especially a kind of continuous casting middle water containing opening.
Background technology
At present, along with the development of continuous casting technology, stricter requirement has been proposed for the mouth of a river of continuous casting tundish.Along with the progress of refractory technology, the requirement of production technology has been satisfied at the aluminium carbonaceous mouth of a river basically, has been widely used in the continuous casting production.
The characteristic limitations of aluminium carbonaceous mesophase water-coating port itself stoving time and baking temperature.Stoving time is too short, is easy to generate crackle at the cast initial stage, even produces cold steel; Stoving time is long, can reduce the service life at the mouth of a river again.Baking temperature is low excessively, causes nozzle blocking easily; Baking temperature is too high, then can reduce mouth of a river intensity.Generally make the mouth of a river reach 1100 ℃ or higher slightly in 1～2 hour, the incipient stage of heating up simultaneously should be rapidly heated, and reaches more than 600 ℃ in the short as far as possible time.
At present, the apparatus for baking that many enterprises use all can't reach the optimum efficiency of baking, exists shortcomings such as baking speed is slow, baking temperature is low, has influenced the quality of continuous casting billet.
Summary of the invention
The purpose of this utility model provides the online apparatus for baking of a kind of continuous casting middle water containing opening, and this device has fast baking, baking temperature height, saves the discharging of consumption of energy consumption and low pollutant.
The utility model is realized by the following technical solutions:
The online apparatus for baking of continuous casting middle water containing opening, this device is made up of body of heater, injection smoke exhaust pipe, compressed air hose, flow control valve, is provided with the circular port that a continuous casting tundish inserts in middle, body of heater top, is provided with sealing device around the circular port; The body of heater bottom is provided with exhaust opening and communicates with the injection smoke exhaust pipe, is provided with compressed air hose on the injection smoke exhaust pipe, and compressed air hose is provided with flow control valve.Be provided with muffler in injection smoke exhaust pipe end.
The course of work of the present utility model is: adopt compressed air as power, utilize the injection smoke exhaust pipe to extract flue gas in the body of heater out.Flow control valve is housed above the compressed air line, controls exhaust smoke level by regulating compressed-air actuated flow, thus baking temperature, programming rate and the stoving time at the control mouth of a river.The sealing device sealing is adopted in the junction of the mouth of a river and body of heater, prevents to reduce baking quality because of stove sucks cold wind.Simultaneously on the injection smoke exhaust pipe muffler is installed, the noise in the time of can subduing the induction tunnel smoke evacuation improves operating personnel's working environment.
The beneficial effects of the utility model are, fast baking, baking temperature height, temperature homogeneity are good, toast adjustable-speed simultaneously.Utilize the flame that carried out heat exchange with middle cylinder-packing to toast the mouth of a river, can improve the utilization rate of heat.

The specific embodiment
See Fig. 1, the online apparatus for baking of continuous casting middle water containing opening, the online apparatus for baking of continuous casting middle water containing opening, this device is made up of body of heater 5, injection smoke exhaust pipe 2, compressed air hose 3, flow control valve 4, body of heater 5 is cylindrical, and outside diameter is between 300～600mm, highly is between 400～700mm, the body of heater inner surface is lined with refractory material, and its thickness is between 80～200mm.Be provided with the circular port of the about 180mm of a diameter in middle, body of heater 5 top, continuous casting middle water containing opening 9 inserts from this circular port, is provided with sealing device 8 around the circular port, and body of heater sucks cold wind from the external world when preventing to toast.Body of heater 5 bottoms are provided with exhaust opening and communicate with injection smoke exhaust pipe 2, are provided with compressed air hose 3 on injection smoke exhaust pipe 2, and by the ejector action smoke evacuation of compressed air hose 3, compressed air hose 3 is provided with flow control valve 4 can carry out the adjusting of exhaust smoke level.Be provided with muffler in injection smoke exhaust pipe end, be used to reduce the noise that blast injection brings.Bottom of furnace body is equipped with two directional wheels and a universal wheel, at the body of heater sidepiece handle 6 is installed, and can promote apparatus for baking and enter accurate operating position.
During work, open the flow control valve 4 above the compressed air hose 3, produce negative pressure in body of heater, the heat in the tundish enters body of heater 5 by middle water containing opening, thereby middle water containing opening is heated.Can adjust flow control valve 4 according to the requirement of baking temperature and baking speed, adjust the heat that enters in the body of heater 5.
