METHODS FOR HEATING A METALLIC VESSEL IN A GLASS MAKING PROCESS

Methods for making a glass article are described that include flowing molten glass through a metallic vessel, and supplying alternating electrical currents to multiple electrical circuits, each electrical circuit including a power supply, a pair of adjacent electrical flanges connected to the power supply, and a portion of the metallic vessel extending between and in electrical communication with the pair of adjacent flanges. At least two adjacent electrical circuits of the multiple electrical circuits share an electrical flange that is a common electrical path for the two adjacent electrical circuits, the two adjacent electrical circuits being supplied with alternating electrical currents, wherein at least one of the electrical currents is cut by a phase-fired controller. 描述了制作玻璃制品的方法，所述方法包括：使熔融玻璃流动通过金属容器；和向多个电路供应交流电流，每个电路均包括电源、连接到所述电源的一对相邻的电凸缘、和所述金属容器的延伸于该对相邻凸缘之间且与该对相邻凸缘电连通的一部分。所述多个电路中的至少两个相邻电路共用一个电凸缘，所述电凸缘是所述两个相邻电路的共同电路径，所述两个相邻电路被供应交流电流，其中所述电流中的至少一个被相爆控制器切断。
