Ordinary flat glass by cutting, milling, cleaning and pretreatment, steel processing into tempered glass production line. Tempered glass production line made up mainly of furnace and cooling grille, curved tempered glass should also pressure moulding station. Glass first enters the heating furnace, in a furnace heated to 600LC, the temperature has reached the softening point of glass. Heated glass is then quickly sent to cooling stations, blower powerful wind evenly through the windshield into two large glass surfaces,GlassRapid cooling, contraction of the internal cooling of the surface, after the internal cooling, when Interior was gradually cooling, internal cooling surface constraints on the close places, and formed in the surface stress, formed in the internal tensile stresses.
