APPARATUS FOR MANUFACTURING GLASS

摘要

PURPOSE: An apparatus for manufacturing glass plate is provided to block the flow of gas containing volatile tin from a floating bath to a dross box by maintaining the internal pressure of the dross box which is relatively higher than the downstream pressure of the floating bath. CONSTITUTION: An apparatus for manufacturing glass plate(100) includes a floating bath(110). A dross box(120) is adjacently arranged to the downstream end part of the floating bath. A reflow unit(130) is installed in the dross box. The reflow unit maintains the pre-set temperature of the dross box and the internal pressure of the dross box. The flow of gas containing volatile tin from the downstream of the floating bath is returned to the upstream of the floating bath. The reflow unit includes a gas supplying part supplying inert gas to the upstream of the floating bath.
