[0002] A bell-type furnace is a heat treatment furnace with a furnace body in the shape of a cover, or a fixed furnace bottom and a movable furnace cover, or a fixed furnace cover and a movable furnace bottom, and is used for batch heat treatment heating of workpieces. At present, during the annealing process of the bell-type furnace, the titanium coil becomes soft when heated, and the edges will be deformed under the action of its own gravity, affecting the overall quality of the titanium coil. Therefore, it is necessary to design a convection plate between two titanium coils during the annealing process of the bell-type furnace titanium coil, so as to effectively avoid the problem of damage to the edges of the titanium coil during the annealing process and improve the processing quality of the titanium coil. Summary of the Utility Model

[0004] The technical solution of the utility model is: a convection plate for a bell-type furnace includes two circular external convection plates with the same size. The central circular opening of the external convection plate is the first ventilation hole. A plurality of hoisting connection plates are evenly distributed at equal intervals between the two external convection plates. The hoisting connection plate is an isosceles trapezoid with an arc-shaped upper base. The upper base of the hoisting connection plate is adapted to the arc edge of the first ventilation hole. The lower base of the hoisting connection plate extends outside the external convection plate. An internal support plate and an intermediate connection plate are successively connected between the plurality of hoisting connection plates and one of the external convection plates. The central circular openings of the internal support plate, the intermediate connection plate and the external convection plate are the same; it also includes multiple groups of second ventilation holes. The second ventilation holes penetrate through the external convection plate, the hoisting connection plate, the internal support plate and the intermediate connection plate. Each group of second ventilation holes consists of a plurality of second ventilation holes arranged in sequence. Each group of second ventilation holes is symmetrically arranged along the diameter direction of the external convection plate, and each group of second ventilation holes is arranged between every two hoisting connection plates.
[0005] The beneficial effects of the utility model are as follows: The structure of the utility model is simple, compact, convenient and fast to use, intuitive and highly practical. By arranging the utility model between two titanium coils during the annealing process of the bell-type furnace titanium coil, the first ventilation hole and the second ventilation hole can realize convection, facilitate the circulation of argon gas, make the steel coil evenly heated, increase the contact area with the edges of the titanium coil, effectively avoid the problem of damage to the edges of the titanium coil due to lack of convection during the annealing process, and improve the processing quality of the titanium coil.
