AirStreamTM ---Radiation heating plays a main role during glass heating, while compressed air is injected into heating furnace, in which it brings certain amount of heat onto glass top surfaces and is helpful for even heating on-line low-E glass, etc. LD-AC AirStream F&B bi-directional tempering furnace adopts AirStream heating technology and they both have a flat quenching section and a bending quenching section that lie on both sides of the heating furnace. By loading the glass in different direction, the furnace can temper both flat and bent glass. Glass can be tempered includes: on-line Low-E glass, extra white glass, silk-printed glass, pattern glass, tinted glass, clear glass, etc. Technical Features: 1) There are flat tempering section and C bending tempering section on both sides of the heating section; by loading the glass in different direction, the furnace can temper flat and bent glass; 2) It adopts AirStream heating technology; it can temper on-line Low-E glass, extra white glass, silk-printed glass, pattern glass, tinted glass, clear glass, etc; 3) It can temper good quality flat and bent glass for architectures.
