How to adjust the glass flatness using air valve in the air distribution box of glass tempering furnace?

Source: LandGlass  Attention: 143  Published: 2019-06-25

When the air valve in the air distribution box is in the middle position, the corresponding pointer indicates zero. The indicator reading points to positive values when the air valve moves up and points to negative values when it moves down.

If the tempered glass bends upwards, it means that the wind pressure on the upper part of the chiller in the tempering section is low. At this point, adjust the air valve downward or to the direction of negative value. To the contrary, when it bends downwards, adjust the air valve and move it to the direction of positive value.
