Structure for putting bricks into annealing electric stove hearth

Abstract

The invention discloses a structure for putting bricks into an annealing electric stove hearth. A fan-shaped included angle of a brick-putting body is made 60 degrees; and a convex arc groove and a concave arc groove are formed at protrusion parts of two side surfaces of the fan shape and can be exactly fastened with grooves on adjacent bricks. A flange is formed in an excircle direction for putting the bricks along the excircle direction; and an inward semicircular groove is formed on the inner side of the flange to serve as a place for accommodating and fixing an electric stove wire. The structure has the advantages that: due to the reduction of joints between bricks, the whole heat insulation effect of the electric stove wire is improved and the electric energy consumption is reduced; meanwhile, because the electric stove wire can be effectively arranged and positioned, an accident probably caused by ageing and falling off of the electric stove wire is avoided.

Description

technical field [0001] The invention relates to a structure for placing bricks in a hearth of an annealing electric furnace, in particular to a structure for placing bricks in a hearth of an annealing electric furnace, and belongs to the technical field of industrial heat treatment equipment. Background technique [0002] Electric annealing furnace is the main heating equipment used in the heat treatment process. In all heat treatment electric annealing furnaces at present, the bricks carrying the electric furnace wire are all small in size, similar to rectangular parallelepiped bricks. The outstanding problems of this kind of bricks are: along the circumference The layout of the furnace needs to be trimmed, which increases the time taken for equipment installation and maintenance. At the same time, the joints are not tight. Due to the small size, the amount of bricks used is correspondingly increased, so the joints also increase accordingly. The overall thermal insulation p...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for overcoming the unreasonable structure of bricks in the furnace of the existing annealing circuit: the use of bricks is large, installation and maintenance are inconvenient, there are many joints between bricks, and the furnace is lowered. At the same time, in order to overcome the defect that the existing brick end has no protruding flange and the electric furnace wire is easy to fall off, the invention provides a structure for annealing electric furnace hearth brick, using this brick, can effectively avoid the above defects
