1 概述 退火窑是浮法玻璃生产线三大热王设备之一。其主要任务是消除玻璃中的残余内应力和光学不均匀性,稳定玻璃内部结构,保证玻璃带在退火窑内各区的降温速度。但随着设备使用年限的增加,窑体老化,辊道变形使得退火窑的退火工况陷入混乱,造成玻璃炸裂次数增加,成品率下降。现就某厂300 t/d退火窑冷修改造进行讨论。……  相似文献

随着浮法玻璃工业的迅速发展,如何改善和提高玻璃的退火质量,越来越引起各厂家的关注.退火技术是浮法厚玻璃生产中的关键因素,它将直接影响到玻璃产品的质量,也将影响到玻璃的生产、储存、运输、深加工等.近年来我国不少浮法生产线采用STEIN公司的退火窑,它在生产控制技术上有一定的特点.本文对STEIN退火窑生产12 mm浮法玻璃的退火控制做了简要分析.  相似文献

A computerzed system was developed and integrated into a thermally polished glass line to control the temperature parameters in its annealing lehr. This served to optimize the annealing of Metelitsa glass, to cut down to 2 h the time required for the lehr to attain steady-state operation, and to raise the glass yield to 0.75. Suitable prompts were devised for operators in charge of the annealing operation, and the optimal format was found for the presentation of information about the on-going process. Translated from Steklo i Keramika, No. 7, pp. 3–5, July, 1997.  相似文献

Conclusions As a result of our investigations for the first time we were able to develop a method for determining the density without breaking silica products, based on the use of correlation relationships between density and group I parameters, the permitted limits of which can be determined by the control chart method.The method developed was checked and introduced for the specification of silica at the Pervourals Factory. This method enables us to accelerate the specification by a factor of 10–12 times compared with a pycnometric method, and by seven times compared with the rapid method.Translated from Ogneupory, No. 1, pp. 9–12, January, 1968.  相似文献
