Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a whole air brick top protection device, whole air brick includes brick cup 9, inlays in the brick cup 9 and is equipped with at least one brick core 10, and the device is including setting up framework 1 at brick cup 9 top, separates at least one region corresponding with brick core 10 in the framework 1, and regional intussuseption is filled with the pouring material.

When processing, build whole air brick by laying bricks or stones behind the package bottom position of ladle, place the top of whole air brick with the device to make brick core 10 correspond the setting in the below of pouring material can, because protection device has shielded brick core 10, so can effectively avoid building by laying bricks or stones the ventilative passageway of in-process brick core 10 and blockked up, guaranteed the gas permeability of brick core 10. After the brick core 10 is put into use, the castable is eroded by molten steel, and normal use of the brick core 10 can be guaranteed.

Furthermore, the top of the brick core 10 is higher than the brick cup 9, the bottom of the casting material is provided with a brick core protection chamber 4, and the brick core 10 correspondingly extends into the brick core protection chamber 4. The core 10 can be easily positioned by the core protection chamber 4 and the device is prevented from shifting on the brick cup 9.

Referring to fig. 1 and 2, when there is only one brick core 10 in the brick cup 9, there is only one area in the frame 1, and the area is filled with the porous protection layer 3. The porous protection layer 3 can be made of a light-weight casting material or a diffuse porous material, wherein the light-weight casting material can be an alumina hollow ball casting material, and the diffuse porous material can be a foam casting material, a porous ceramic material or a diffuse brick.

Referring to fig. 3 and 4, when two or more brick cores 10 are embedded in a brick cup 9, a first region and at least one second region are separated from the frame 1, the brick cores 10 are correspondingly arranged below the first region or the second region one by one, the first region is filled with the porous protection layer 3, the second region is filled with the heavy castable 7, and the top of the heavy castable 7 is embedded with the indicator rod 6. Specifically, the first brick core 10 is disposed below the porous protection layer 3, and the remaining brick cores to be used are disposed below the heavy castable 7.
