Abstract
The invention discloses a gas curtain, comprising a casting body and a ventilate plate fixed on the casting body. A gas chamber is molded between the casting body and the ventilate plate, and is communicated with outside through a ventilating pipe. The invention has simple structure and good ventilation property. The gas chamber is formed through the ventilating plate and the casting body, and gas penetrates the ventilating plate through the ventilating pipe after entering the gas chamber so as to remove impurity in substances to be purified, improve the cleanliness and quality thereof.
Description
Technical field
The present invention relates to a kind of air curtain barricade wall.
Background technology
At present, along with applying of China's high-efficient continuous casting technology, the continuous pouring stove number of continuous casting and the pulling rate of continuous casting improve constantly, and occur two new problems again.Steel-passing amount and molten steel flow speed increase aggravation molten steel wash away refractory material, and the slag weir refractory products descends service life; The molten steel flow speed increase has reduced the time of non-metallic inclusion come-up relatively, and the purification of molten steel effect is weakened to some extent.As a whole, the tendency of the needs of high-efficient continuous casting technology development has appearred satisfying in the slag blocking wall refractory products.
Summary of the invention
The object of the present invention is to provide the air curtain barricade wall on a kind of tundish, can prolong the non-metallic inclusion floating interval of floating dock, strengthen purification of molten steel effect, long service life.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: comprise pour mass and be fixed on air permeable plate on the pour mass that form air chamber between described pour mass and the air permeable plate, described air chamber is in communication with the outside by breather pipe.
Preferably, described air permeable plate is connected with the pour mass cast; Cast connects simple and convenient, and relatively firmly, good seal performance prevents that the gas leakage from causing energy waste.
Preferably, described pour mass is provided with one and is used to connect extraneous fixed part.Pour mass and extraneous contact area are increased, can make connection more firm.
Preferably, described fixed part is arranged on the both sides of pour mass.Both sides are provided with more can strengthen firm degree, and can keep inherent balance.
Preferably, the left side wall of described pour mass is provided with the groove of ccontaining breather pipe, and the right side wall of described pour mass is provided with the groove of ccontaining breather pipe, and the diapire of described pour mass is provided with the groove of ccontaining breather pipe; Place tracheae according to actual conditions in different azimuth.
Compared with prior art, advantage of the present invention is: form an air chamber by air permeable plate and pour mass, pass air permeable plate after entering air chamber by tracheae by gas, get rid of the impurity in the material to be clean, improve its cleanliness factor, improve the quality.

The specific embodiment
As the embodiment of Fig. 1-Fig. 5 for a kind of air curtain barricade wall of the present invention, a kind of air curtain barricade wall, comprise pour mass 1 and be fixed on air permeable plate 2 on the pour mass 1, form air chamber 3 between described pour mass 1 and the air permeable plate 2, described air chamber 3 is in communication with the outside by breather pipe 4, and described pour mass 1 is connected with air permeable plate 2 cast, cast connects simple and convenient, relatively firmly, good seal performance prevents that the gas leakage from causing energy waste.Described pour mass 1 is provided with one and is used to connect extraneous fixed part 5, and pour mass and extraneous contact area are increased, and can make connection more firm.Described fixed part 5 is arranged on the both sides of pour mass 1, and both sides are provided with more can strengthen firm degree, and can keep inherent balance.The left side wall of described pour mass 1 is provided with the groove 11 of ccontaining breather pipe 4, the right side wall of described pour mass 1 is provided with the groove 11 of ccontaining breather pipe 4, the diapire of described pour mass 1 is provided with the groove 11 of ccontaining breather pipe 4, places tracheae according to actual conditions in different azimuth.
As shown in Figure 6, externally arrive air chambers 3 for the argon gas in the argon device by breather pipe 4, argon gas passes the air permeable plate 2 that is fixed on the pour mass 1, and argon gas is blown in the molten steel in the tundish 5 Ya Qi Shen and looses and form a large amount of trickle bubbles, can adsorb pernicious gases such as N, H in the molten steel, O; Trickle bubble floating plays the effect of stirring molten steel, takes up inorganic non-metallic inclusion floating such as oxide in the molten steel, nitride, sulfide, silicate effectively, makes them be adsorbed by the slag charge of molten steel face.
