技术领域 technical field
本发明涉及玻璃加热加工设备技术领域，具体涉及一种玻璃加热炉及加热方法。 The invention relates to the technical field of glass heating and processing equipment, in particular to a glass heating furnace and a heating method.
背景技术 Background technique
玻璃在（物理）钢化过程中，加热是第一道工序，也是影响玻璃最终钢化质量的最重要工序。目前的钢化玻璃设备中，加热炉是控制过程最复杂、对钢化玻璃产品影响最大的一部分。控制好玻璃的加热过程，是生产出优质钢化玻璃的前提。 In the (physical) tempering process of glass, heating is the first process and the most important process that affects the final tempering quality of glass. In the current tempered glass equipment, the heating furnace is the part with the most complex control process and the greatest impact on tempered glass products. Controlling the heating process of glass is the prerequisite for producing high-quality tempered glass.
玻璃在炉膛内的加热过程是一个炉膛温度下降、升温、均衡的过程；玻璃的加热过程是一个先快速升温、再逐渐均热的过程。玻璃在炉内被加热时不同的时间段需要不同的加热方式来满足玻璃的加热需要，减少常规加热方式对玻璃造成的加工缺陷是每一个设备厂家需要解决的难题。 The heating process of glass in the furnace is a process in which the temperature of the furnace drops, rises, and balances; When the glass is heated in the furnace, different heating methods are required for different periods of time to meet the heating needs of the glass. Reducing the processing defects caused by conventional heating methods to the glass is a difficult problem that every equipment manufacturer needs to solve.
玻璃刚进炉时会造成炉温和陶瓷辊道的温度剧烈下降，这个时候由于玻璃底部接触陶瓷辊道受热传导的影响，玻璃下表面升温很快，而玻璃的上表面受热辐射的影响升温很慢，加热初期玻璃变形很大，容易出现玻璃向上弯曲和大板面玻璃因受热不均反复变形的现象，此时容易造成玻璃出现“白雾”和厚板玻璃的炸裂，而随着上部加热元件的热量补充，玻璃上表面温度逐渐升高，玻璃上下表面的温差减小，玻璃逐渐展平，这个过程大约占玻璃加热过程的20％～30％，此时的玻璃表面与玻璃板中心的温差逐渐缩小，玻璃的升温速度逐渐放慢，这种现象会持续到玻璃的加热结束。 When the glass just enters the furnace, the temperature of the furnace temperature and the ceramic roller table will drop sharply. At this time, because the bottom of the glass contacts the ceramic roller table and is affected by heat conduction, the temperature of the lower surface of the glass rises rapidly, while the temperature of the upper surface of the glass rises slowly due to the influence of heat radiation. , the glass deforms a lot in the early stage of heating, and it is prone to upward bending of the glass and repeated deformation of the large plate glass due to uneven heating. The temperature of the upper surface of the glass is gradually increased, the temperature difference between the upper and lower surfaces of the glass is reduced, and the glass is gradually flattened. This process accounts for about 20% to 30% of the glass heating process. At this time, the distance between the glass surface and the center of the glass plate The temperature difference gradually narrows, and the heating rate of the glass gradually slows down. This phenomenon will continue until the heating of the glass ends.
