2.2 Measures for controlling thermal deformation temperature unevenness due to heating caused by (1) the temperature difference for the upper and lower surfaces, when the glass is bent upward, indicating that the glass surface temperature. Surface temperature should be reduced, while maintaining the overall glass heating temperature constant, an appropriate increase in surface temperature; when the glass is bent downward, indicating that the surface temperature is higher than the surface temperature, the surface temperature should be lower due to lower, while increasing the surface temperature. If at the time of adjusting the temperature, tempered steel yield and quality are affected, respectively, an appropriate extension of the heating time or reduce the heating time. (2) For the deformation temperature difference caused by the presence of glass in the middle and edge, if the glass showing saddle-shaped, indicating poor insulation or furnace temperature setpoint lower edge, you need to adjust the temperature set point edge; when When the glass bottom of the pot shape rendering, if due to historical reasons, can temporarily laying glass, the first air furnace operation, the furnace temperature is evenly distributed and then poorly; if the temperature setting issue, the need to adjust the temperature setting parameters, so furnace temperature distribution. (3) for the random uneven temperature, you need timely maintenance equipment, to avoid adverse device status, often to clean up broken glass near the temperature sensor, the temperature sensor is accurate to feel the temperature of the furnace, while the topsheet is to avoid more furnace in the same state stacked. 2.3 Measures for controlling thermal deformation due to uneven cooling caused by the stress generated in the cooling process is uneven, the cooling rate can be adjusted by adjusting the glass surface air pressure gate. If the glass is bent downward, which can be adjusted by increasing the pressure at the bottom of the grille to improve cooling rate of the surface under glass; if the glass bending upward, through the upper portion of the gate to increase the wind pressure on the glass surface to increase the cooling rate regulation.
