1. Suitable for manufacturing flat/bend tempered glass of higher quality, especially suitable for manufacturing low-E Glass, coated-glass, patterned-glass, etc. 2. Heat speed improved about 25% over other radiant heating furnaces of the same type, capacity increased about 3.25%, Time of glass staying in fumace decreased, scratch on lower surface of glass is minimized. 3. Heat absorption of the glass upper surface and lower surface is uniformed; Heat evenness of the whole glass is highly improved, Thereby can completely eliminate the glass white smoke phenomenon and thick glass crack within the furnace. 4. The heat oven adopts the upper convection heating methods which can easily even the heating in the glass upper side and lower side, also can ensure the glass optical performance and mechanical properties after the tempering. 5. All the Metallic Materials and elements in the heating furnace are made of anti-high temperature and anti-oxidation material
