Evaluation of bubble removing Performance in a TV glass furnace : Part 2. Verification using real furnace data

Abstract

In part 2, a furnace for melting TV panel glass is studied to examine the effectiveness of the Simulator developed by the authors. Because panel glass is used as a part of a cathodic ray tube where the TV image is projected and its defect is easily recognizable, bubble-free glass quality is defmitely required. If the bubble quality becomes worse, a heap of rejected products is piled up, which leads to tremendous economical loss. In order to avoid such trouble designing and operating a TV glass furnace and inspecting glass quality are conducted with great care, and therefore, lots of field data have been accumulated so far. Accordingly, it is meaningful to utilize a TV glass furnace to verify the effectiveness of such simulating technology. The values and phenomena predicted by the Simulator and the data having been observed in real furnaces were found to be in reasonable agreement. Therefore, it may be concluded that the proposed Simulator is useful as a method of scale-up and trouble-shooting for glass furnaces.
