Heating furnace brick holding frame structure

Abstract

The invention discloses a heating furnace brick holding frame structure which comprises a brick holding plate, a brick pulling rod and a heating furnace wall plate. The brick pulling rod is in a strip-shaped structure. The cross-section of the strip-shaped structure is F-shaped. Two shorter sides parallel to each other of the F-shape cross section are connected with the heating furnace wall plate. The brick holding plate comprises a plate body and a support. A bending portion towards the reverse surface of the plate body is arranged on one edge of the plate body. The support is connected with the reverse surface of the plate body. The support is L-shaped. One side of the L-shaped support is connected with the plate body. The bending portion of the plate body is fastened on the longer side of the L-shaped support. The other side of the L-shaped support directs toward the bending portion and abuts against the heating furnace wall plate. Due to the structure of the heating furnace brick holding frame, the heating furnace brick holding frame structure can be manufactured in a casting mode and applied to various heating furnaces. In this way, novel alloy materials can be selected to use, and heat-resistant property of the heating furnace brick holding frame structure is improved.

Description

technical field [0001] The technical proposal relates to a brick support plate, in particular to a novel casting type heating furnace brick support structure. Background technique [0002] The brick support plate is a part used to support the refractory brick in the lining structure of the heating furnace. It is a very important and indispensable part for the furnace wall of the light brick support structure, especially for high-temperature heating furnaces (like those in petrochemical plants) Ethylene cracking furnace, hydrogen conversion furnace, etc.), the structure and material of the supporting brick board, the quality of construction and installation, all directly affect the stability of the furnace wall structure, the service life of the furnace lining, the temperature of the wall surface of the furnace shell and the appearance of the furnace heat loss. [0003] The existing heating furnace pallet bricks are commonly used in the following two forms: [0004] The fir...

Problems solved by technology

This avoids the problem that the long steel plate is easily deformed during welding and use, and the brick supporting plate is not in direct contact with the furnace shell plate. It is better than direct contact, but the disadvantage of this structure is that when the quality of a single supporting brick plate is not good and the welding quality of the angle steel is not good, it is difficult to adjust the level of the adjacent brick supporting plate during installation.
