Research on Temperature Distribution Rule of Glass Mold During Surfacing
The rule of temperature distribution of glass mold during surfacing were measured with G90-SAT thermal infrared imager. The results show that the temperature distribution of glass mold is complicated during surfacing and the regular of thermal circle of every point on the glass mold is low-high-highest-high-low, and the temperature is the highest when it is remelted. Thermal surfocing is a flash heating and cooling process the temperature in the upper surface of glass mold exists inhomogeneity and asynchronism during thermal surfacing.
