Abstract
The utility model discloses a composite permeating brick which comprises a composite permeating brick body and a permeating slit. The utility model is characterized in that a permeating ceramic rod is arranged inside the composite permeating brick body, the permeating slit is arranged outside the permeating ceramic rod, and a gas passage is arranged inside the permeating ceramic rod. The composite arrangement of the permeating slit and the permeating ceramic rod can provide enough gas passages in the limited volume to ensure the requirement for the gas flow rate in the refinement process. The ceramic rod arranged in the composite permeating brick has extremely high strength, which is beneficial to enhance the scour resistance performance and the service life of the permeating brick.
Description
Technical field
The utility model relates to the gas supply element that a kind of furnace for treating liquid steel is used, and relates in particular to a kind ofly when high-temperature molten steel is handled, and being used for supply gas carries out gas stirring to reach a kind of composite air bricks of even composition and temperature.
Background technology
During steel-making, be the inclusion floating in the promotion molten steel, even molten steel composition and temperature, the quality of raising steel adopts stirring technique to come molten steel is handled more, and gas stirring is comparatively common a kind of alr mode.Tradition gas permeable brick air path part all is made up of slit, because ladle is increasing, thereby require the gas permeable brick gas supply capacity also more and more higher, in the so less space of gas permeable brick, often a large amount of slits to be set, gas permeable brick just is divided into a large amount of small unit, and isolated substantially between each unit, the gas permeable brick globality is destroyed bigger, be subjected to easily to produce after the molten steel scouring problem such as peel off, reduced work-ing life.Gas-permeable channels is if be made up of slit fully simultaneously, because material character and gas circuit structure, molten steel can more seriously cause through-blowing rate lower to wherein permeating.
Gas permeable brick in the market mostly is the slit structure of chrome corundum, because ladle generally develops towards the high capacity direction at present, this requires gas permeable brick that very strong gas supply capacity and higher through-blowing rate are arranged; On the other hand, for improving the quality of steel, ladle adopts refining process such as LF, LF+VD, LF+RH in a large number, and this makes that the working conditions of gas permeable brick is more abominable, and the life-span is shorter; Present slot-type ventilating brick can not satisfy above-mentioned service requirements.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides the composite air bricks that a kind of gas supply capacity is strong, through-blowing rate is higher, work-ing life is long.
The technical solution of the utility model is achieved in that a kind of composite air bricks, and permeable-gas ceramics rod and ventilative slit are arranged in the composite air bricks body, wherein in the permeable-gas ceramics rod gas passage is arranged.
The permeable-gas ceramics rod be shaped as cylindrical or cuboid.
The gas passage is distributed as uniform distribution or uneven distribution in the permeable-gas ceramics rod.
The gas passage can be pore and also can be slit and also can be the disperse structure that forms by control material granularity, grating in the permeable-gas ceramics rod.
The quantity of permeable-gas ceramics rod is the 1-15 root in the composite air bricks, preferred 3-6 root.
Ventilative slit integral body in the composite air bricks is annular, and annular quantity can be 1-5 ring.
Compared with prior art the beneficial effects of the utility model are: the permeable-gas ceramics rod passes through the pyroprocessing mistake in advance, has improved the through-blowing rate of composite air bricks; Ventilative slit and the compound setting of permeable-gas ceramics rod can be provided with abundant gas passage to guarantee the requirement of refinery practice to gas flow in limited volume; The permeable-gas ceramics rod that is provided with in the composite air bricks has high intensity, helps improving the scour resistance of composite air bricks, improves the life-span of composite air bricks.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail, as shown in Figure 1, a kind of composite air bricks, this composite air bricks gas circuit is made of two portions: permeable-gas ceramics rod gas circuit and slit gas circuit, gas can be fed to molten steel by gas passage in the ceramic rod 3 and ventilative slit 4 and carry out gas stirring.
Permeable-gas ceramics rod 2 and ventilative slit 4 are arranged in the composite air bricks body 1, permeable-gas ceramics rod 2 is in advance through 1100 ℃ of-2000 ℃ of pyroprocessing, be high temperature ceramic material, the material that these pyroceramic rods can be types such as zirconium dioxide, zircon corundum constitutes, shapes such as that permeable-gas ceramics rod 2 can be is cylindrical, cuboid; Permeable-gas ceramics rod 2 is in advance through the pyroprocessing mistake, as its quality of a kind of high temperature ceramic material can be fine and close more, intensity is higher, performance is more stable, has improved the ballistic performance of anti-molten steel, has stablized the gas permeable brick quality, has improved gas permeable brick work-ing life.
Permeable-gas ceramics rod 2 is in gas permeable brick inside, the gas passage of composite air bricks is by gas passage 3 in the permeable-gas ceramics rod 2 and 4 compound compositions of ventilative slit, prevented that molten steel is to exosmosis, avoided the reduction of through-blowing rate, permeable-gas ceramics rod 2 its high-density, low pore, high-intensity performance make molten steel significantly reduce to the infiltration of gas passage, thereby have improved the through-blowing rate of composite air bricks simultaneously.
Gas passage 3 in the composite air bricks in the permeable-gas ceramics rod 2 can be also can be uneven uniformly in the distribution of permeable-gas ceramics rod 2, preferred uniform distribution; The shape of gas passage 3 can be pore, slit etc., even can be the gas circuit that forms by the control material grain composition.Because high-temperature molten steel is different with the wettability of traditional gas permeable brick constituent material to high temperature ceramic material, molten steel also can be lower to the perviousness of the gas passage 3 of permeable-gas ceramics rod 2; Gas passage 3 in the permeable-gas ceramics rod 2 even the disperse structure that can form by the grain composition and the particle diameter of control ceramic rod material also are obviously feasible as the gas passage.
The quantity of the permeable-gas ceramics rod 2 in the composite air bricks is the 1-15 root, can reach same purpose equally, and the quantity of preferred permeable-gas ceramics rod 2 is the 3-16 root.
Ventilative slit 4 integral body in the composite air bricks are preferably annular, and annular quantity can be encircled for 1-5.
The utility model is not limited to the foregoing description, and for the professional in present technique field, any improvement that the utility model embodiment is made or change can not exceed the protection domain of spirit of the present utility model and claims.
