Submerged plate for selective diversion of molten metal flow in a glass forming chamber

摘要

A glass forming chamber wherein glass is formed while floating on the surface of a pool of molten metal is provided with a submerged plate in the pool of molten metal, which plate is contoured to divert the flow of molten metal in a central portion of the pool beneath an advancing layer of glass and to cause the flow of molten metal from the central portion into marginal portions of the pool or vice versa.
