FURNACE AND METHOD OF BENDING GLASS AND SHEET MADE BY THIS METHOD

摘要

FIELD: glassmaking furnaces. SUBSTANCE: furnace has at least one zone of differential heating formed by great number of heating elements; furnace is provided with shield located in differential heating zone on the same side of glass sheet to be bent where heating elements are located. This shield is used to deliver the heat radiated by heating elements in desired direction owing to which controllable differential heating of glass may be obtained. EFFECT: accurate control of profile of temperature distribution over sheet and consequently improved control of desired form.
