C, as a forced convection heating mode of the main: gas heating furnace and air forced convection furnace regarded as one of the main heating. With the rapid spread of market applications can be tempered glass shelf, using forced convection oven temperature fan or compressed air may also be developed. A forced convection heating mode, the heating time can be shortened glass, improve production efficiency, the glass temperature more uniform, improve product quality. Currently using forced convection oven tempered glass windows, to less than 6mm transparent glass heating time can reach 27s / mm. Quenched glass is toughened glass in the process one of the most important aspects of 12mm tempered glass, glass forming its final stress plays a decisive role. By steel processing glass, can effectively enhance the mechanical strength of the glass. Physical, chemical methods, so that the flat glass surface compressive stress layer, resulting in permanent stress evenly distributed so as to obtain the deep processing of high-strength and high thermal stability methods of glass that is tempered glass. Physical steel, also known as hot steel method, the other is chemical tempering method. Physical tempered glass is the glass is heated to below the softening temperature before rapid and uniform cooling.
