摘要:
Method for monitoring molten state of a glass batch charged into a melting bath of a glass melting furnace, and a method and control device for controlling an amount of a glass batch to be so charged. Regions to be measured are set in regions corresponding to particular partial regions on an image obtained by capturing an image of a liquid surface of the bath to be monitored using a camera. The occupying ratio of an area occupied by image portions representing unmolten glass batches in each region, and a distribution state of the batches in the partial region is recognized from the measured value of the occupying ratios so as to determine whether the molten state quality of the batch is favorable. When the determined quality is not favorable, the amounts thereof to be charged by batch chargers are controlled so that appropriate distribution states can be obtained.

In order to allow vertical ventilation in a plurality of circumferential locations around the contour surface of a mold in the process of molding and regulate the temperature, the ventilation is carried out using an abutting path formed between the abutting surfaces of inner and outer members forming the contour surface part and its outer peripheral part of the mold, thereby achieving cooling. In this way, various shapes based on the axially changing shape of the contour surface are obtained readily and inexpensively, and temperature control suitable for the axially changing shape of the contour surface is carried out with high cooling effect.
