Float Glass Float into the production process which leads to the protection of gas in the tin bath complete. From the pool of molten glass into the kiln in a row and floating in the relative density of the liquid tin surface, in the role of gravity and surface tension, the glass surface on the liquid in the tin rolled out, spread flat, forming the upper and lower surface roughness, hardness, cooling after the transition onto a roller sets. Roller roller station rotation, pull the glass with a tin bath into the annealing kiln。
