一、引言随着玻璃工业的发展,玻璃池窑的熔化率不断提高,相应地熔化温度高了,池窑中的玻璃流加快,导致将未熔化好的玻璃液带到作业池中,从而降低了玻璃液的化学均匀性和温度均匀性。为了解决这个问题,当前发展趋势是采用强化玻璃熔融技术,鼓泡技术是强化熔融过程的一种先进而又可靠的手段之一。 相似文献

An important step in the optimization of a glass container production cycle is the determination of the glass temperature distribution during heat treatment. The ideal approach to this problem is to formulate a theoretical model for comparison against experimental data measured in a well-determined system. Discrepancies between theory and experiment may then give further direction for model improvement. This approach, however, is limited because of the difficulties in measuring glass temperature distribution during forming.
Another approach is to use the model to predict glass surface heat fluxes during the forming cycle and test the computed results against published values of glass to metal heat fluxes measured during glass container production on an individual section (I.S.) Blow-and-Blow bottle machine.
A computer model has been developed to calculate the temperature distribution in a glass plate. The model includes the three modes of heat transfer: conduction, convection and radiation. The process is complicated by simultaneous internal emission and reabsorption of radiant energy within the glass in the non-opaque region of the spectrum. With the problem being simplified to a one-dimensional case, the glass plate is divided into several slices. An energy balance on each slice yields a system of integro-partial differential equations which are solved to obtain the temperature distribution.
Results in the form of temperature-time, temperature-distance and surface heat flux-time plots arc presented and compared with published models and with experimental data. 相似文献
