Convection heationg plays main role during glass heationg. After being heated in jet convection chamber, the hot air inside heating furnace is blown onto glass surfaces and then goes back to hot air blowers for contiuous circulation, which not only ensure even heating, low production costs, but enhance the quality of the end products as well. LD-AL JetConvection Continuous Flat Tempering Furnace LD-AL JetConvection continuous flat tempering furnace adopts JetConvection heating and AirStream heating technologies; it is suitable for tempering high quality, large volumes flat glass for architecture and furniture. Glass can be tempered includes: on-line and off-line Low-E (E=0.03) glass, extra w
