| COMPLETE MACHINE DESCRIPTION |
| Machine Description |
NorthGlass AG-1E50 fifth-generation full-convection flat glass tempering furnace
designed for high-productivity tempering of float, coated, body-tinted, enameled
and low-emissivity glass. The line incorporates automatic loading, a thermally
insulated heating chamber, upper and lower continuous forced convection,
flat-glass quenching and cooling, automatic unloading, centrifugal fan stations,
air ducts and a computerized process-control system. |
| Maximum Processing Format |
Maximum working width is 2,850 mm (112.20 in). Maximum loading length is
5,000 mm (196.85 in) for 5–19 mm glass and 4,600 mm (181.10 in) for 4 mm glass.
Minimum glass size is 150 × 300 mm (5.91 × 11.81 in). |
| Full-Convection Technology |
Upper and lower forced-convection systems use heat-resistant open-pipe structures,
high-temperature superalloy fans and independently controlled heating zones.
The interleaved radiation and convection arrangement is designed to improve
temperature uniformity between the center and edges of the glass and reduce
thermal defects. |
| Automation |
Computerized operation includes recipe storage, automatic loading control,
temperature and tempering-process controllers, inverter-controlled drives,
self-diagnostics, fault warnings, automatic preheating, process visualization,
service diagnostics and remote diagnostic capability. |
| Production Capability |
At the document’s stated 65% loading condition, indicative float-glass productivity
ranges from 24 loads per hour for 4 mm glass to 3 loads per hour for 19 mm glass.
These figures are based on tests using 1 × 2 m glass and may vary according to
actual glass dimensions. |
