摘要： The invention relates to a method for annealing flat bodies, especially flat bodies consisting of an amorphous, inorganic material, especially flat glass panes or glass ceramic panes. One or more of the flat bodies are subjected to a heat treatment within a temperature range between room temperature and the respective glass transition temperature. The invention is characterized in that said heat treatment is carried out in an annealing container and in that said annealing container is configured in such a way that it is closed sufficiently to prevent impurities from the environment surrounding the annealing container from coming into contact with the flat body.

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 DEG C, notably at between 20 and 1705 DEG 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.

摘要： The invention relates to an easy and affordable method for precompressing flat glass panes in which a high temperature homogeneity is guaranteed in the glass. At least one flat glass pane which is situated on at least one ceramic plate is subjected to a thermal treatment ranging from 300 DEG C to 900 DEG C in radiation furnace. Said ceramic plate comprises a caloric conductibility which is at least 5 times greater in the range of the thermal treatment temperature than that of the glass pane which is to be treated. Such ceramic plates with a certain thickness can be used such that the relationship of the entire thickness of the ceramic plates to the glass staple height amounts to at least 1/ lambda . 40 W/mK, whereby lambda represents the caloric conductibility of the ceramic material in the range of the thermal treatment temperature.

摘要： The invention relates to a method for relaxing stress in glass, especially at the base of the neck of a television funnel, comprising at least the following steps: the glass which is to be relaxed is heated from an initial temperature T1 to a holding temperature T2; said glass is maintained at the holding temperature T2 for a period of time t2 until the glass has relaxed; the glass is cooled to a temperature T3 which is always less than T1; the temperature T2 is maintained, and the heating and cooling processes are carried out by means of a regulating circuit comprising at least one temperature sensor for detecting the temperature and one heating unit as a control element. The invention is characterised in that the heating unit comprises infrared beam emitters for heating the glass which is to be relaxed, said beams having a thermal delay time of less than 10 s, especially less than 5 s.
