Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings.
As shown in fig. 1 and 2, the whole air brick of the present invention comprises an air brick seat 3 and a first air brick core 1 and a second air brick core 2 arranged in the air brick seat 3. The top end of the first air brick core 1 protrudes upwards and is exposed outside the air brick seat brick 3, the second air brick core 2 is embedded in the air brick seat brick 3, and the upper part of the second air brick core is covered by a covering layer 8 formed by the air brick seat brick. The height of the first gas permeable brick core 1 at the setting position is higher than that of the second gas permeable brick core 2, and during use, the first gas permeable brick core 1 is firstly utilized to blow argon. The protruding height of the top end of the first air brick core 1 is set according to requirements, and the distance between the top end of the first air brick core 1 and the upper surface of the air brick seat brick can be selected within the range of 0-20 mm.
The covering layer 8 is used for protecting the second gas permeable brick core 2 from being eroded when the first gas permeable brick core 1 works normally, the thickness of the covering layer 8 is determined according to the eroded speed and the effective working height of the second gas permeable brick core 2, and the second gas permeable brick core 2 is not exposed when the first gas permeable brick core 1 is used normally, for example, the thickness can be selected to be 20-50 mm.
When the first core 1 is eroded to a safe standard height with use, the first core 1 is stopped and the vent pipe is transferred to the second core 2. At this time, in order to put the second core 2 into use, it is necessary to remove the coating layer 8 on the second core 2 as soon as possible. For the purpose of facilitating the removal of the cover layer 8, the top surface of the second gas brick core 2 is spaced from the cover layer 8, so that an interlayer space 4 is formed between the top surface of the second gas brick core and the cover layer. The specific height of the interlayer space 4 is determined according to the brick core size, the thickness of the covering layer, the material hardness of the air brick seat brick and other factors, and the specific height is larger than the deformation amount which can be borne by the covering layer 8 on the principle, so that the lower part cannot be supported by the top of the brick core when the covering layer is knocked to be broken, for example, about 10 mm. The second air brick core 2 can have the use condition by pounding or burning the covering layer 8 formed by the air brick seat brick on the second air brick core by an oxygen lance, thereby efficiently replacing the brick core for continuous use and prolonging the service life of the air brick under the state that the ladle is not stopped.
And a silicon carbide rod 5 is embedded in the covering layer above the second air brick core 2, and compared with the surrounding air brick seat brick materials, the silicon carbide rod has darker color at the same temperature, relative to the surrounding, the color is blackened, and the embedded position of the second air brick core 2 can be clearly marked. When the upper covering layer 8 is broken, the breaking range can be accurately determined, and burning deviation can be prevented.
When the first gas brick core 1 is switched to the second gas brick core 2, gas is introduced through a pipeline at the tail part of the second gas brick core 2, and enters the interlayer space 4, so that the interlayer space 4 becomes a gas chamber. The gas in the gas chamber can reduce the temperature of the covering layer 8 to some extent, while the silicon carbide rod 5 becomes darker relative to the surroundings. Therefore, the interlayer space 4 (i.e., the air chamber) is not only favorable for removing the covering layer, but also can make the marker (i.e., the silicon carbide rod) in the covering layer more conspicuous, and is favorable for determining the breaking range.
As shown in fig. 3, the first air brick core 1 and the second air brick core 2 are distributed along the diagonal line of the air brick seat brick 3, and the size of the air brick seat brick 3 on the diagonal line is the largest, so that the distance between the first air brick core 1 and the second air brick core 2 can be effectively increased, the mutual influence between the first air brick core and the second air brick core can be avoided during working, and the safety of the whole brick is improved.
As shown in figure 1, the tails of the first air brick core 1 and the second air brick core 2 are connected with a one-way check valve 6 through pipelines, so that the situation that the slit clamps steel due to the fact that the argon is suddenly closed and the negative pressure generated in the moment is effectively prevented, and the blowing-through rate is improved. The one-way check valve 6 is made of high-temperature-resistant stainless steel, and can ensure that the ladle does not lose efficacy when being baked at high temperature.
The air brick seat brick 3 can be designed into a rectangle shape or a cylinder shape at two sides according to the building requirement of the ladle, the material is corundum spinel, and the molding process is casting molding. The interlayer space can be filled with low-melting filler in advance, so that the integral molding of the air brick is facilitated. The whole air brick is heated after the ladle is put into use, low-melting substances are melted or burnt at a certain working temperature, and the interlayer space 4 forms an air chamber which can be filled with air.
And safety marks are arranged in the first air brick core and the second air brick core, and the safety marks can also be made of silicon carbide and used for indicating the safe working height of the brick cores. When the brick core burns out to the safe mark position, indicate promptly that to have used to safe limit, need switch the brick core or change whole air brick.
And air passages are reserved between the first air brick core and the second air brick core and between the air brick seat bricks, and the air passages are in slit type, dispersion type, plate splicing type or ceramic rod through hole type.
The rest of the non-description can refer to the prior air brick technology, and the detailed description is not repeated.
