Problems solved by technology
After the pointing is completed, the galvanized sheet cannot be removed in this formwork support method, and it is always between the self-flowing castable of the pointing material and the anhydrous press-in mud, which leads to an increase in the thermal conductivity of the refractory material after the blast furnace is put into operation
In addition, the galvanized iron sheet is flexible, and the fixing method of 18# iron wire cannot withstand the high-strength pneumatic hammer construction, so that the quality of joint joints on the cold surface of the cooling wall cannot be guaranteed, and there are cases of looseness and unreliable ramming; the labor intensity cannot use machinery

The invention relates to a cooling wall pointing template structure capable of being detached and circularly used and an application method of the cooling wall pointing template structure. The cooling wall pointing template structure comprises a strip-shaped template and L-shaped fasteners. The strip-shaped template is vertically arranged on the outer side cooling face of the cooling wall. A plurality of grooves are formed in the strip-shaped template in the length direction. Through holes are formed in the bottoms of the grooves. The flat head ends of the L-shaped fasteners transversely penetrate out of the through holes and penetrate the cooling wall to be connected with lock nuts at the other end of the cooling wall. Supporting plates are clamped between the lock nuts and the cooling wall. The cooling wall pointing template structure is simple and has the beneficial effects of being high in strength, capable of being circularly utilized and high in installing efficiency.
Description
technical field [0001] The invention relates to the field of pointing construction after stave installation, in particular to a detachable and reusable stave pointing formwork structure and a use method thereof. Background technique [0002] In the traditional pointing construction of staves, 0.5-1mm galvanized sheet is punched and then fixed with 18# iron wire. After the pointing is completed, the galvanized sheet cannot be removed in this formwork support method, and it is always between the self-flowing castable of the pointing material and the anhydrous press-in mud, which leads to an increase in the thermal conductivity of the refractory material after the blast furnace is put into operation. In addition, the galvanized iron sheet is flexible, and the fixing method of 18# iron wire cannot withstand the high-strength pneumatic hammer construction, so that the quality of joint joints on the cold surface of the cooling wall cannot be guaranteed, and there are cases of loos...
