Novel ventilation brick

Abstract

The invention relates to a novel ventilation brick. The novel ventilation brick comprises a ventilation brick core (1), and a ventilation brick base brick (2) arranged at the external of the ventilation brick core (1); elastic stoppers (3) are symmetrically arranged at the side part of the ventilation brick core (1); and positioning holes (4) for extending in the elastic stoppers (4) are formed in the corresponding parts of the ventilation brick base brick (2). The novel ventilation brick is provided with the elastic stopper; the elastic stoppers are extruded in the assembly process; the ventilation brick core can be conveniently assembled in the ventilation brick base brick only by overcoming the elastic force; as the elastic stoppers with the structure are only suffered from the extruding force, the elastic stoppers are not easy to damage; once the elastic stoppers enter the positioning holes, the elastic stoppers are turned due to disappearing of external force, that is, the assembly is finished; and due to existent of the elastic stoppers, the position of the ventilation brick core is fixed without generating the loosening phenomenon.

Description

technical field [0001] The invention relates to the technology for improving air-permeable bricks in the field of steelmaking, in particular to a novel air-permeable brick. Background technique [0002] In the field of steelmaking, the side wall of the ladle is provided with air-permeable bricks, and the air-permeable bricks are connected with gas pipelines to facilitate the gas blowing process in the ladle. The fixed strength of the final air-permeable brick is not enough, and it will loosen, which will not only affect its air-permeable performance, but also cause molten steel to seep into the brick joint, causing blockage and unfavorable repair problems. [0003] Therefore, the patent with the announcement number of 202845768U provides a new type of breathable brick. Its structure is: by setting the breathable brick core in the breathable brick seat brick, and setting the fixed piece to fix it, but in this structure, due to the existence of the fixed piece, It will form a...
