Method of manufacturing flat glass, flat glass of the buffer layer forming apparatus and flat glass manufacturing facilities

摘要

Production method of the sheet glass whose it is possible to substitute to the means forming of the buffer coat which uses former SO_2, to control the occurrence of the , the buffer coat formation device of the sheet glass and production equipment of the sheet glass are offered. Supplying melted glass 5 to the horizontal bath surface 1b of the melted metal bathtub 1 which accommodates the melted metal continually, with the forming step which forms glass ribbon 6 and conveying glass ribbon 6 to annealing furnace 3, you adopt the production method of the sheet glass which features that the buffer coat which consists of the occurrence inhibiter is formed for the underside 6of a glass ribbon 6, the annealing process which the annealing it does in the production method of the sheet glass which has, in the process after the forming step.
