HETEROGENEOUS GLASS DISCHARGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a heterogeneous glass discharge device for removing heterogeneous glass floating on a surface layer of molten glass which can contribute to suppress generation of inferior quality of a product and a decrease in yield of the molten glass by preventing an overflow control block for controlling the flow rate of the molten glass discharged from a discharge port from being corroded by the molten glass according to a use period. ! SOLUTION: A heterogeneous glass discharge device 1 separates and removes heterogeneous glass HG floating on a surface layer of molten glass G by installing a shelf part 32 in a discharge port part 30, which is a discharge port of the molten glass G, to make the molten glass G overflow from the shelf part 32. The heterogeneous glass discharge device 1 includes an overflow control block 40 that is mounted on a top surface of the shelf part 32 for controlling the height of the shelf part 32. The entire surface of the overflow control block 40 is made of pl
