Abstract

The invention discloses a box-type annealing furnace, which comprises a box body; the box body is provided with a mounting frame, the mounting frame is provided with a multi-layer bracket, the bracket is provided with a tray, and the tray is covered with through holes; A heating layer and a fan are arranged on the inner wall of the box; the box body is equipped with a box door, and a sealing layer is arranged on the edge of the box door, and the box door is equipped with a door lock. When the box-type annealing furnace guarantees the quality of the glass after annealing treatment, the annealing treatment period is greatly shortened. It takes 7 days to complete the annealing treatment in the original, and it can complete an annealing treatment in 4 days.

Description

technical field [0001] The invention relates to the technical field of glass annealing, in particular to a box-type annealing furnace. Background technique [0002] Annealing refers to slowly heating the glass to a certain temperature, maintaining it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects. [0003] When the existing glass is annealed, many glass blocks are filled into the box. During annealing, many glasses in the box cannot be heated evenly, resulting in poor quality of the annealed glass, and the annealing cycle is long, reducing production. efficiency. Contents of the invention [0004] The object of the present invention is to provide a box-type annealing furnace to solve the deficiencies of the prior art. [0005] For realizing the objec...
