The depth of the molten glass cooling unit area is 0.15- 0.9 m within the region, by cooling glass liquid flat area calculation, at each interval of 0.2-2 m2, installing 1-5 heating device and 1-5 temperature measuring device. The process method and heating device process control program design prerequisite is: when there is change in glass flat line appears to rise and fall, glass flat line appeared to rise and fall with varying degrees of change, or when the amount of cooling molten glass unit changes, especially, producing large breakdown, or molding section due to maintenance or operation, or as part generating fault or change production, or for forming process of drawing amount change, change product thickness equal debugging, or work order of glass forming product failure, or annealing product order breakdown, or work order producing malfunction, or the bag work order generating failure, or avoiding adding or not glass liquid for maintaining equal 13 large series production process status, when the safe gate is set to the cool part device; at this time all the heating device process control program designed for the increased heating power device. Heating plant process controlling programming process prerequisite: when the glass flat line appears to rise and fall changes, the glass flat line also appeared to rise and fall with varying degrees of change, or the amount of cooling molten glass unit changes, especially generate large breakdown, or forming section on the maintenance or operation, or as part generating fault or change production, or for forming process of drawing amount change, change product thickness equal debugging, or work order of glass forming product failure, or annealing product order breakdown, or work order producing stay malfunction, or the bag work order generating failure, or to not avoid on and not adding glass liquid for maintaining equal 13 large series production process status, when the safe gate is set to the cool part device, at this time, the process control program designed for the crystallization temperature when the glass liquid temperature measuring device measured temperature is less than 50 degrees C, starting heating device, especially increasing the heating device power, device power to set heating power of the heating device as high as 3-10 times at normal production time which is large.

The thickness of the flat glass is: 0.7-1.5 mm; 0.5-0.7 mm; 0.4-0.5 mm; 0.3-0.4 mm;0.1-0.3 mm; 1.6-3 mm; 3.1-6 mm;6.1-12 mm; 12.1-25 mm. EXAMPLE - 3% sodium oxide, 29% alumina, 44.4% silicon oxide, 13.9% calcium oxide, 9.7% magnesium oxide was taken, which was mixed completely, then the material was entered into the melting device, the glass liquid was preset and formed, then introduced into cooling part for cool clarification, heating device was set for heating, after cooling glass liquid from cooling part, the glass was leveled, polished and pulled thin, then by glass belt guide was used to pull via edge rolling machine of tractor traction, after cutting and package, flat glass was prepared with rupture strength of 186 Mpa, glass glass thickness less than 0.4 mm, water absorption of 0-1%, expansion rate of 54 at 20- 100 degrees C, expansion coefficient changes at 450-600 degrees C of 2-3 parts per million.
