Method and apparatus for homogenising molten glass by stirring

摘要

A method and apparatus for making float glass, the apparatus being a furnace (1) comprising a melting zone (2), a refining zone (7) and a conditioning zone (8) communicating with the refining zone (7). The outlet (16) from the conditioning zone (8) leads into a float canal (13). Stirring by means of stirrers (15a,15b) having a shaft (17) projecting downwardly into the molten glass (6) and a stirring device having a generally rectangular configuration, major and minor axes of different dimensions and being coplanar with the axis of the shaft, is effected in the conditioning zone (8) adjacent the entrance (16) to the float canal (13). <IMAGE>
