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.
A tempering furnace control system is comprised of a host computer and a slave computer. The host computer adopts either an internationally renowned brand IPC or TP1200 made by Siemens A&D Group.
A combined glass tempering furnace is primarily comprised of loading table, pre-heating section, heating section, tempering section, cooling section, unloading table, and control system.
