【摘要】：通过玻璃钢化炉炉内的玻璃和辊道仿真研究,使我们认识了玻璃钢化过程中玻璃和辊道的三维温度场的变化规律。改变工艺参数,可较为方便地得到不同工况条件下玻璃钢化的仿真结果,例如在钢化炉的基本参数确定的工况下,以玻璃的长度为变量时,玻璃与辊道接触的根数最好小于三根,且玻璃长度对辊道三维温度场的影响很小等,这些结果可为玻璃钢化过程提高质量和降低能源消耗提供重要的参考和依据。然后对玻璃钢化流程以及需要的仿真软件作出简单的介绍,论文运用传热学和流体力学的相关知识,在合理假定的基础上,建立起玻璃钢化过程中玻璃和辊道的数学模型,并确定出玻璃和辊道的边界条件。在设置仿真的方案时,以玻璃的长度、宽度、厚度为变量,以辊道的直径、长度、间隙为变量,以钢化炉炉内的工作温度为变量,仿真并得出玻璃及辊道三维温度场的变化规律。由此可知,玻璃钢化市场存在着质量低和能耗大等各种问题,对玻璃及辊道三维温度场进行研究和分析,可有针对性地采取相应措施,在一定程度上提高玻璃钢化的质量,降低能耗,在未来的玻璃钢化市场中,可以提高市场的竞争力,生产出多样化的钢化玻璃。
[Abstract]:Through the simulation study of glass and roller table in glass tempering furnace, we know the change law of three dimensional temperature field of glass and roller table in the process of glass tempering. The simulation results of glass hardening under different working conditions can be easily obtained by changing the process parameters, for example, under the condition of determining the basic parameters of the tempering furnace and taking the length of the glass as the variable, The contact number between glass and roller is better than three, and the length of glass has little effect on the temperature field of roll table. These results can provide important reference and basis for improving quality and reducing energy consumption in the process of glass tempering. Then the process of glass tempering and the simulation software are introduced briefly. The mathematical model of glass and roll table is established on the basis of reasonable assumption by using the knowledge of heat transfer and hydrodynamics. The boundary conditions of glass and roller table are determined. In setting up the simulation scheme, the length, width and thickness of glass are taken as variables, the diameter, length and clearance of roller table are taken as variables, and the working temperature in the furnace is taken as variable. The three-dimensional temperature field of glass and roller table is simulated and obtained. It can be seen that there are many problems in glass hardening market, such as low quality and large energy consumption. To study and analyze the three-dimensional temperature field of glass and roller table, we can take corresponding measures to improve the quality of glass tempering to a certain extent. Reduce energy consumption, in the future glass toughening market, can improve the competitiveness of the market, the production of a variety of tempered glass.
