Abstract

The invention discloses a glass annealing device and method. The glass annealing device comprises a mesh belt annealing furnace, wherein the mesh belt annealing furnace is provided with a hearth; heating devices are arranged on the four faces of the inner wall of the hearth; a heat preserving region and a cooling region are formed in the hearth; a heating section is formed in the hearth, and is partitioned into a plurality of section units; and the plurality of section units constitute a heat preserving region and a cooling region from front to back respectively. In the glass annealing device and method, the conventional mesh belt annealing furnace is lengthened, annealing control sections are increased, and control accuracy is increased specific to a glass production requirement, so that secondary annealing is not required, production procedures are reduced, turnover steps for semi-finished glass are reduced, and product yield is increased.

Description

technical field [0001] The invention relates to a glass annealing device and an annealing method, and relates to the field of glass manufacturing annealing. Background technique [0002] The stress index in the field of glass manufacturing is one of the important indicators to measure the quality of glass. Generally speaking, the smaller the stress, the better the performance of the product. At present, in order to obtain glass products with good stress, glass manufacturers generally adopt the method of secondary annealing, that is, the once-formed products undergo secondary annealing treatment to eliminate the residual stress generated during the primary forming process and obtain products with very small stress. Secondary annealing equipment usually adopts mesh belt annealing furnace and square annealing furnace. The operation method is to heat the normal temperature product that has been formed once to the annealing temperature; after a certain period of time, the inter...
