Annealing Lehr for Float GlassProduction Line

The annealing lehr for float glass production line heats the glass to theupper limit of the annealing temperature range. After a period of thermalretardation, the permanent stress in glass is eliminated. Then the glass iscooled down at an appropriate rate to the lower limit of the annealingtemperature range, so it will not produce a new permanent inherent stress. Fromwhat is mentioned above, we know there is a slow cooling process involved inannealing.

We are a China-based manufacturer of annealing lehrfor float glass production line. We offer full set of annealing lehr equipment, annealing lehrdrive and transmission system, continuous heating flat glass tempering furnace,glass cross cutting machine, and much more.
