Abstract: A glass heating furnace is illustrated. Rollers of the glass heating furnace are pivotally connected to a movable frame, and a roller driver of the glass heating furnace controls the rollers to rotate to a direction of an X axis, and a movable frame driver controls the movable frame to displace reciprocatively along a Y axis, such that the rollers displace along the Y axis at the same time. The glass displaces reciprocatively in multiple directions to be heated up more uniformly, which effectively reduces formation of the thermal stress marks on the glass. Since the rollers displace along the Y axis at the same time, the glass on the rollers does not have the displacement of the Y axis in respect to the rollers, such that friction of the displacement of the glass is reduced, which more effectively reduces formation of the thermal stress marks on the glass.
