METHOD FOR MONITORING GLASS MELTING FURNACE, METHOD FOR CONTROLLING INTRODUCTION OF RAW MATERIAL, AND DEVICE FOR CONTROLLING INTRODUCTION OF RAW MATERIAL

摘要

Provided are a method for monitoring a molten state of a glass batch charged into a melting bath 2 of a glass melting furnace, and a method and a control device for controlling an amount of a glass batch to be charged into the melting bath 2 using such a method. Regions 21L, 21R 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 melting bath 2 to be monitored using a camera 6. The occupying ratio of an area occupied by image portions representing unmolten glass batches 70 in each of the regions 21L, 21R to be measured is measured, and a distribution state of the unmolten glass batches 70 in the partial region is recognized from the measured value of the occupying ratios so as to determine whether the quality of the molten state of the glass batch is favorable or not. When it is determined that the quality of the molten state of the glass batch is not favorable, the amounts of the glass batch to be charged into the melting bath 2 by batch chargers 4L, 4R are controlled so that appropriate distribution states can be obtained.
