摘要： A glass manufacturing system is described herein that has an elongated forming device (e.g., elongated isopipe) which was made longer by attaching two extensions to two ends of a body so it can be used to make a larger glass sheet. The elongated forming apparatus includes the body and two extensions which when connected to one another have a trough formed therein in which molten glass flows and then overflows two top surfaces of the trough and runs down opposites sides of the body and two extensions before fusing together to form the glass sheet. A method for making glass sheets using the glass manufacturing system and the elongated forming apparatus is also described herein.

摘要： Isopipes for use in making sheet glass by a fusion process are provided which exhibit reduced sag. The isopipes are composed of a zircon refractory which has a mean creep rate (MCR) at 1180° C. and 250 psi and a 95 percent confidence band (CB) for said mean creep rate such that the CB to MCR ratio is less than 0.5, the MCR and the CB both being determined using a power law model. The zircon refractory can contain titania (TiO2) at a concentration greater than 0.2 wt. % and less than 0.4 wt. %. A concentration of titania in this range causes the zircon refractory to exhibit a lower mean creep rate than zircon refractories previously used to make isopipes. In addition, the variation in mean creep rate is also reduced which reduces the chances that the zircon refractory of a particular isopipe will have an abnormally high creep rate and thus exhibit unacceptable sag prematurely.

摘要翻译：提供用于通过熔融方法制造玻璃板的等压管，其具有减小的下垂。等压管由锆石耐火材料组成，其在1180℃和250psi下具有平均蠕变速率（MCR），对于所述平均蠕变速率为95％置信带（CB），使得CB与MCR的比率小于0.5 ，MCR和CB都是使用幂律模型来确定的。锆石耐火材料可以含有浓度大于0.2wt。的二氧化钛（TiO 2）。％且小于0.4wt。％。在这个范围内，二氧化钛的浓度使得锆石耐火材料的平均蠕变速率低于先前用于制造等压管的锆石耐火材料。此外，平均蠕变速率的变化也降低，这降低了特定等压槽的锆石耐火材料将具有异常高的蠕变速率并因此过早地显示不可接受的凹陷的机会。
