摘要： Automatic heating controls for heating of glass sheets and methods utilizing such controls are provided so that area temperatures approach plus or minus 1 degree Fahrenheit of area desired temperatures, in a steady state operation through a furnace having heaters. Area temperatures and area desired temperatures are combined to obtain area temperature errors. The area temperature errors, area setpoint temperatures, and a comparison of adjacent area temperatures and/or area setpoint temperatures are then applied to integral-only feedback control so as to provide area furnace system demand. For thick glass (i.e., greater than approximately 3mm thickness) core temperatures are included to obtain temperature errors. Then, area furnace system demand is utilized to adjust the heat output of the heaters, the speed of the transport system, or both. Following a gap in the flow of glass sheets, the area temperatures are returned to steady state operation within 10 minutes.
摘要翻译：提供用于加热玻璃板的自动加热控制和利用这种控制的方法，使得在通过具有加热器的炉的稳态操作中，面积温度接近正或负1华氏度的区域所需温度。区域温度和面积所需温度相结合以获得面积温度误差。区域温度误差，区域设定点温度以及相邻区域温度和/或区域设定点温度的比较然后被应用于仅积分反馈控制，以提供面积炉系统需求。对于厚玻璃（即，大于3mm厚度），包含核心温度以获得温度误差。然后，利用区域炉系统需求来调节加热器的热量输出，运输系统的速度，或两者。在玻璃板流动之后，面积温度在10分钟内恢复到稳定状态。
