Abstract
A system and method is provided for tempering a glass container. The method includes the steps of pre-heating the glass container to a first predetermined temperature. The method also includes the steps of applying radio-frequency energy to the pre-heated glass container to heat the glass container to a second predetermined temperature and, after a predetermined amount of time, simultaneously cooling at least one surface of the heated glass container to a third predetermined temperature to treat the glass container. The method further includes the steps of, after a predetermined amount of time, quenching the treated glass container to a fourth predetermined temperature to produce a tempered glass container.
Claims11
A system for tempering a glass container comprising:
- a radio-frequency energy source having a plurality of substantially rectangular plates vertically orientated and horizontally spaced relative to each other to apply radio-frequency energy to a pre-heated glass container to heat the glass container to a predetermined temperature, wherein the glass container receives the radio-frequency energy and the radio-frequency energy heats the glass container to the predetermined temperature;
- a spindle adapted to support and transport the glass container between said plates;
- a quench tube including a portion adapted to be disposed inside of the glass container, said quench tube adapted for allowing air to pass therethrough and into the glass container to thereby quench the glass container and produce a tempered glass container;
- and
- wherein each of said plates includes a plurality of air-outlet holes spaced vertically from each other on an inside surface of said radiation plate for supplying air to an outside surface of the glass container.
A system for tempering a glass container comprising:
- a radio-frequency energy source having a plurality of substantially rectangular radiation plates vertically orientated and horizontally spaced relative to each other to apply radio-frequency energy to a pre-heated glass container to heat the glass container to a predetermined temperature;
- a plurality of plenums supplied with air under positive pressure, each of said plenums including a plurality of air nozzles disposed on an inside surface thereof and spaced vertically from each other for allowing air to pass therethrough to cool an outside surface of the heated glass container to cool the glass container;
- a spindle adapted to support and transport the glass container between said plates;
- and
- a tube including a portion adapted to be disposed inside of the glass container, said tube adapted for allowing air to pass therethrough to an inside surface of the heated glass container to cool the glass container.
