GLASS MANUFACTURING APPARATUS AND METHODS

A glass manufacturing apparatus may include a portion of a conduit positioned within an internal bore of a refractory tube. In one embodiment, the refractory tube includes a first heating element operable to heat a first length of the refractory tube and a second heating element operable to heat a second length of the refractory tube. In another embodiment, a forming vessel includes an inlet and alower end of the refractory device is positioned within the inlet. In further embodiments, methods of manufacturing glass include flowing molten material along the flow axis through the interior pathway of the conduit. In some embodiments, the method includes flowing molten material through an outlet of a downstream segment of a delivery pipe positioned within the inlet. 玻璃制造设备可以包括位于耐火管的内孔中的一部分导管。在一个实施方式中，耐火管包括第一加热元件和第二加热元件，所述第一加热元件能够运行成对耐火管的第一长度进行加热，以及所述第二加热元件能够运行成对耐火管的第二长度进行加热。在另一个实施方式中，成形容器包括入口，并且耐火装置的下端置于入口内。在其他实施方式中，制造玻璃的方法包括使熔融材料沿着流动轴流动通过导管的内部路径。在一些实施方式中，方法包括使熔融材料流动通过位于入口中的传递管的下游区段的出口。
