To ensure a smooth lifting of the glass tempering furnace unit, spray certain amount of N46 lubricant oil to lubricate the trapezoidal screw in the pillar after every lift of the furnace top (or at least once a month).
During the remaining 5 seconds of heating for the glass in the glass tempering furnace, the rear door of the furnace will open in order that the glass can be discharged from the heating section in time. after the rear end of the glass leaves the furnace, the bending mechanism will begin to work.
During the installation of the ceramic rollers in the glass tempering furnace, place the conveyor rack of the ceramic rollers in the vicinity of the place to be installed first. At least three people would lift up one end of the ceramic rollers to be placed on the roller conveyor rack and slowly push it into the glass tempering furnace.
（1）Belt drive
The ceramic rollers on a glass tempering furnace are driven by O-ring belt and synchronous belt;
（2）Chain drive
Roller drive for loading and unloading tables;Roller drive for C-bent/B-bent;
The cooling water in the forced convection glass tempering furnace recirculation system takes away the heat from the enclosure of the convection blower when it flows through the furnace.
1. Surface stress of the glass can be tested with a surface stress meter by placing carefully the test instrument on the glass surface after applying a few drops of immersion liquid at the bottom of the instrument.
Flat glass is divided into tempered glass, semi-tempered glass, and annealed glass based on their surface stresses. According to U.S. ASTM C1048-1997b standard, the ranges of surface stresses for each type of glass are: Tempered glass >69MPa (10,000psi), Semi-tempered glass: 24MPa (3500psi) ~ 52MPa (7500psi).
Full Convection glass tempering furnaces are the ones that use convection heating method on both upper and bottom sides of glass. All the glass types mentioned above can be tempered by full convection glass tempering machine.
The national economic boom and improvement of people’s living standard have led to higher market demand for glass products, with emphasis on product safety, energy saving and quality, such as: dual-pane laminated tempered glass, Low-E glass and other processed products.
