Description
Technical field
The utility model relates to the apparatus for baking of continuous casting tundish submersed nozzle.
Background technology
Conticaster tundish submersed nozzle is a kind of steel stream protective casing that is used between tundish and the crystallizer, and is oxidized because of ingress of air in the process of injecting crystallizer to prevent the molten steel in the tundish, influences the quality of continuous casting billet.Because submersed nozzle directly contacts with molten steel, because of the moisture that includes contacts with molten steel explosion takes place for preventing submersed nozzle when casting, must toast submersed nozzle before use.
At present, the method to the submersed nozzle baking is divided into two kinds: first method is separately submersed nozzle to be toasted, and generally adopts baking box to toast, but this kind baking method energy consumption is bigger, is unfavorable for environmental protection; Another kind method is to utilize the heat that is produced when tundish toasted that submersed nozzle is toasted synchronously, to reach the purpose of energy savings.
At second kind of baking method, Chinese patent ZL97238682.3 discloses a kind of air suction type mouth of a river apparatus for baking, this apparatus for baking links to each other the air hose of combustion-supporting usefulness with mouth of a river roaster, the gas that flows by the air hose high speed makes in the roaster of the mouth of a river and produces negative pressure, thereby make heat in the tundish enter the mouth of a river roaster mouth of a river is toasted.This apparatus for baking also has been injected into harmful exhaust in the air hose of combustion-supporting usefulness when utilizing waste heat, makes that oxygen content descends in the combustion-supporting air, influences cured effect.
Need a kind of apparatus for baking can guarantee the oxygen content of combustion air for this reason, can make full use of tundish baking heat again submersed nozzle is toasted, utilize heat energy as much as possible.
The utility model content
The purpose of this utility model is to provide a kind of apparatus for baking of continuous casting tundish submersed nozzle, this apparatus for baking can make full use of tundish baking heat submersed nozzle is toasted, effectively improved the service efficiency of heat energy, simultaneously can also play pre-heat effect to the air in the air hose, improve the calory burning of burner, reduce energy resource consumption.
The utility model is achieved in that
A kind of apparatus for baking of continuous casting tundish submersed nozzle, comprise: tundish, clad, submersed nozzle, burner, Gas Pipe, air hose, first centrifugal blower, the bottom of tundish has the duct, be provided with submersed nozzle in the duct, the top of tundish is provided with clad, have through hole on the clad, be provided with burner in the through hole, one end of burner is arranged in the tundish, the other end of burner links to each other with Gas Pipe, air hose, Gas Pipe communicates with outside gas pipeline, and air hose communicates with extraneous air behind first centrifugal blower; Described apparatus for baking also comprises second centrifugal blower, exhaust column, sleeve pipe, discharge pipe, the lower end of submersed nozzle is arranged in the sleeve pipe, one end of exhaust column communicates with sleeve bottom, the other end of exhaust column communicates with the air inlet of second centrifugal blower, and the air outlet of second centrifugal blower communicates with discharge pipe.
Described discharge pipe is sleeved on the described air hose outside.
Fill up high temperature resistant soft material in the slit between described submersed nozzle and the sleeve pipe.
The utility model is provided with sleeve pipe in the lower end of tundish bottom submersed nozzle, and second centrifugal blower communicates with sleeve bottom by exhaust column, by the running of second centrifugal blower, is bled in the lower end of submersed nozzle, thereby forms negative pressuren zone.Under the effect of negative pressure, the heat in the tundish flows downward and the whole submersed nozzle of process, thereby submersed nozzle is carried out heated baking, has effectively improved the service efficiency of heat energy.After having toasted, the waste gas that has heat is discharged outside the apparatus for baking through the discharge pipe of second centrifugal blower.Because discharge pipe is sleeved on the air hose outside, so the waste gas in the discharge pipe can play pre-heat effect to the air in the air hose, thereby improved the calory burning of burner, reduced energy resource consumption.
Description of drawings
Fig. 1 is the apparatus for baking structural representation of the utility model continuous casting tundish submersed nozzle.
Among the figure: 1 submersed nozzle, 2 tundish, 3 clads, 4 burners, 5 air hoses, 6 Gas Pipe, 7 first centrifugal blowers, 8 second centrifugal blowers, 9 exhaust columns, 10 sleeve pipes, 11 discharge pipes, 12 asbestos cords.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of apparatus for baking of continuous casting tundish submersed nozzle comprises: tundish 2, clad 3, submersed nozzle 1, burner 4, Gas Pipe 6, air hose 5, first centrifugal blower 7, second centrifugal blower 8, exhaust column 9, sleeve pipe 10, discharge pipe 11.
The top of tundish 2 is provided with clad 3, has through hole on the clad 3, is provided with burner 4 in the through hole.One end of burner 4 is arranged in the tundish 2, and the other end of burner 4 links to each other with Gas Pipe 6, air hose 5.Gas Pipe 6 communicates with outside gas pipeline, imflammable gas, and for example coal gas or natural gas can be transported to burner 4 places by Gas Pipe 6, for burner 4 burnings provide combustion gas; Air hose 5 communicates with extraneous air behind first centrifugal blower 7, for burner 4 burnings provide combustion air.The heat that produces during burner 4 burnings toasts tundish 2, and 3 pairs of tundish 2 of the clad at tundish 2 tops play insulation effect.
The bottom of tundish 2 has the duct, is provided with submersed nozzle 1 in the duct.The lower end of submersed nozzle 1 is arranged in the sleeve pipe 10, and with high temperature resistant soft material the slit between submersed nozzle 1 and the sleeve pipe 10 is filled up.In the present embodiment, high temperature resistant soft material selection asbestos cord 12.One end of exhaust column 9 communicates with sleeve pipe 10 bottoms, and the other end of exhaust column 9 communicates with the air inlet of second centrifugal blower 8; The air outlet of second centrifugal blower 8 communicates with discharge pipe 11, and discharge pipe 11 is sleeved on air hose 5 outsides, and promptly discharge pipe 11 is wrapped in air hose 5 outsides of tundish 2 roasting nozzles 4.
The utility model is work like this:
Point burner 4 toasts tundish 2 at the heat that tundish 2 internal combustion produce by burner 4.After having toasted a period of time, start second centrifugal blower 8, by the exhaust column 9 that communicates with second centrifugal blower, 8 air inlets, the sleeve pipe 10 that is arranged on submersed nozzle 1 lower end is bled, thereby form a negative pressuren zone.Under the effect of negative pressure, the heat that is used for tundish 2 bakings flows downward, and the whole submersed nozzle 1 of process, thereby finishes the heated baking to submersed nozzle 1.Simultaneously, the waste gas that has heat of the submersed nozzle 1 of flowing through then by the air outlet of second centrifugal blower 8, is discharged in the discharge pipe 11, discharges outside the apparatus for baking through discharge pipe 11 again.Because discharge pipe 11 is sleeved on air hose 5 outsides, the heat of waste gas has just passed to the air in the air hose 5, be that discharge pipe 11 interior waste gas can play pre-heat effect to being about to carry out combustion-supporting air in the air hose 5, thereby improved the calory burning of burner 4, reduced energy resource consumption.
The utility model can make full use of tundish baking heat submersed nozzle is toasted, and has effectively improved the service efficiency of heat energy, can also play pre-heat effect to the air in the air hose simultaneously, improves the calory burning of burner, reduces energy resource consumption.
