In the process of glass discharging from the heating section, the high pressure blows work for 8-10s.

When the glass travels to the cooling section, small blower is working whie big blower wil turn off.

e quenching section designed by SAll GLAss has passed strict theoretical calculaton and on-site practical test. The diameter and layout of the air grid orifices will be adiusted according to the different types of glass .

The air grid calculates the air pressure and the diameter and layout of the air control.Because the glass surface temperature is geting lower and lower as the lass takes longer to be out ofthe heating section, the length of the glass out of the furnace calculates the due air hole diameter and hole spacing. There are diferences before and after the air holes. lt is dificult to distinguish with eyes ifthe diameter of the air hole is not equipped and the hole spacing is accurate to 0.05mm.
