Abstract
A glass heating furnace is disclosed. The glass heating furnace allows glass to be heated up more uniformly, which reduces effectively the formation of the thermal stress marks on the glass. The glass heating furnace uses primarily a roller power module to control the rollers to displace reciprocatively, allowing the glass to be heated up uniformly and reducing significantly the formation of the thermal stress marks in the heating process of the glass, through the reciprocative displacement of the rollers. A glass is made by the glass heating furnace. The glass displaces in a chamber of the glass heating furnace along an S-shaped moving path or an 8-shaped moving path.
Claims18
A glass heating furnace comprising
- a furnace body, an interior of which is formed with a chamber;
- plural upper heating elements, which are disposed in the chamber, with the center of one upper heating element being separated with the center of a neighboring upper heating element by a first distance;
- plural lower heating elements, which are disposed in the chamber and are located oppositely below the upper heating elements, with the center of one lower heating element being separated with the center of a neighboring lower heating element by a second distance;
- plural rollers, which are disposed in the chamber along a transversal axis and are located between the upper heating elements and the lower heating elements, with the transversal axis being perpendicular to a longitudinal axis and that longitudinal axis being the axis of the rollers;
- and
- a first roller power module, which is disposed outside the furnace body and is connected with the rollers, with the first roller power module controlling the rollers to displace reciprocatively between two pre-determined positions along the longitudinal axis.
