METHOD AND DEVICE FOR THE HOMOGENEOUS HEATING OF GLASS AND/OR GLASS-CERAMIC ARTICLES USING INFRARED RADIATION

摘要

The invention relates to a method for the homogeneous heating of semitransparent and/or transparent glass and/or glass-ceramic articles using infrared radiation so that the glass and/or glass-ceramic articles undergo heat treatment at between 20 and 3000 ~C, notably at between 20 and 1705 ~C. The invention is characterized in that heating is achieved by a component of infrared radiation which acts directly on the glass and/or glass-ceramic articles and by a component of infrared radiation which acts indirectly on said glass and/or glass-ceramic articles. The radiation component indirectly acting on the glass and/or glass-ceramic articles accounts for more than 50 % of total radiation output.
