    Glass Annealing Principle

          Annealed glass is heated first, and then follow the prescribed temperature products for insulation and cooling, so that a permanent glass can reduce stress to the actual allowable value.
          In particular the thickness unevenness articles of glassware, articles of complex shape, the molding was cooled to room temperature and from the temperature of the process,The rapid cooling of glass ,which products to a temperature difference between the inner and outer layers and the shape of the products arising from the relationship parts of the temperature,make glass thermal stress.When products encountered by mechanical impact or thermal shock, the stress will cause product breakdown. In order to eliminate the permanent stress glass, glass products need to be annealed.Annealed glass is heated first, and then follow the prescribed temperature products for insulation and cooling, so that a permanent glass can reduce stress to the actual allowable value.

            Shijiazhuang Wufeng Thermal Machinery Co.,Ltd. supply high quality annealing furnace/lehr.Welcome the customers all world to consult the related products.
