It can be processed in various ways like other high-quality float glass. During the production process, ultra-clear float glass needs to be annealed in a glass annealing furnace. Glass annealing furnace is a thermal equipment that cools the glass ribbon at a certain speed to reduce and homogenize thermal stress. It is an indispensable equipment in the glass production process. The annealing of glass is mainly controlled by fans and valves to control the pressure and flow of the wind, so that the glass is cooled at a certain speed in the annealing furnace.
