Description
Technical field
The utility model relates to a kind of refractory product, particularly relates to a kind of gas permeable brick.
Background technology
Steel ladle bottom argon blowing technology is impurity removing technology conventional in steel-making, its principle is, by being blown into rare gas element from ladle bottom, forms tiny bubble population after gas permeable brick, slag inclusion in molten steel is carried into the slag blanket on molten steel by bubble capture, thus reaches the effect of removal of impurities.Obvious, the distribution range of bubble population is wider, bubble contact to catch the probability of the slag in molten steel higher, and impurity-eliminating effect is also better.But gas permeable brick of the prior art is normally provided with one or several slit, and can only form a small amount of bubble flow, bubble distribution is limited in scope.
In existing patent documentation, the existing dispersive air brick making porous by special technique increases the passage of air-flow, generates the technology of a large amount of bubble flow.Such as, in existing open file, have that notification number is CN201620177U, the day for announcing is the Chinese patent literature of 2010-11-03, disclose a kind of refining composite air bricks with inclusion in efficient removal molten steel, this composite air bricks is made up of two portions: dispersive air brick pressed by the machine that top is even air hole distribution, aperture is less, and bottom is ventilative good non-dispersive air brick; Have air chamber between upper and lower gas permeable brick, upper and lower gas permeable brick is connected by double buckle, and whole gas permeable brick outside adopts parcel steel bushing to be fixed.The advantage of this utility model is: the argon gas of winding-up forms the less bubble population of diameter by top dispersivity gas permeable brick, thus has the performance of inclusion in more excellent removal molten steel.The weak point of this technical scheme is, the volume of dispersive air brick is larger, and the argon gas of input can only be appeared from the upper surface of gas permeable brick by the bubble population generated after this gas permeable brick, bubble population is too concentrated, bubble distribution scope is little, and the effect removing impurity in molten steel is undesirable, and the non-dispersive air brick of top dispersive air brick and bottom is fixed by the mode of outer wrap steel bushing, easily issue raw relative movement in the impact of heat and air-flow, cause molten steel to leak.
Utility model content
For the bubble population overflow table area solving the generation of existing gas permeable brick is little and concentrated, bubble population distribution range in molten steel is little, the problem of impurity-eliminating effect difference, the utility model provides that a kind of bubble formation position is many, bubble population overflow table area is large and disperse, the bubble population gas permeable brick that distribution range is large in molten steel, good impurity removing effect, gas effciency are high.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of gas permeable brick, comprise the air brick body with gas port, the top of air brick body has the mounting groove of bar shaped, the cross section of mounting groove is inverted T-shape, the upper surface of air brick body is run through in the upper end of mounting groove, mounting groove runs through the front and back sides of air brick body along the radial direction of air brick body, air brick body is provided with the breathable block be engaged in mounting groove, the cross section of breathable block is inverted T-shape, breathable block has the disperse pore of some equally distributed minor diameters, air brick body is also provided with air chamber, the lower end of air chamber is communicated with gas port, the upper end of air chamber is communicated with the disperse pore on breathable block.The breathable block that can generate a large amount of bubble population is arranged in the mounting groove of air brick body upper end, make gas permeable brick have good physicals simultaneously, can generate a large amount of simultaneously, large-scale bubble population, namely ensure that gas permeable brick can keep good physicals under the impact of thermal stresses and air-flow, simultaneously a large amount of, on a large scale bubble population too increase the impurity-eliminating effect of Argon technology; By the screens of inverted T-shape structure installment, breathable block can be changed alternative fast, simple to operate, and bubble can generate in the end face of breathable block, side, and move upward along different angular separation, form large-scale bubble population, add the efficiency of removal of impurities and the utilization ratio of gas, improve the quality of molten steel, reduce cost.
As preferably, the end face of breathable block is arc, and exceeds the end face of air brick body.Breathable block end face is arc and exceeds the end face of air brick body, adds the surface-area that bubble occurs, and improves bubble formation scope, improves impurity-eliminating effect.
As preferably, air brick body is provided with some sides air slot, and side air slot is communicated with side and the end face of disperse pore on breathable block and air brick body.Side air slot adds the breather hole of air brick body side, adds the position that bubble overflows, and then increases the distribution range of bubble population in molten steel, improves impurity-eliminating effect.
The beneficial effects of the utility model are: bubble formation position is many, bubble population overflow table area large and disperse, and bubble population distribution range in molten steel is large, good impurity removing effect, gas effciency are high, cost-saving.
