DEVICE FOR FORMING GLASS SURFACE LUBRICATING LAYER, ANNEALING FURNACE AND DEVICE FOR MANUFACTURING GLASS HAVING SAME

摘要

An apparatus for forming a lubricant layer on the surface of a glass prevents scratches from occurring at the surface of a glass and decrease corrosion of glass manufacturing equipment and may be included in an annealing furnace or a glass manufacturing apparatus. The apparatus includes a SO 2 supply unit for supplying SO 2 gas, a O 2 supply unit for supplying O 2 gas, and a catalyst retaining unit for retaining a SO 2 gas oxidation catalyst, the catalyst retaining unit receiving SO 2 gas and O 2 gas from the SO 2 supply unit and the O 2 supply unit to generate SO 3 gas and supplying the generated SO 3 gas to a glass.
