Full Set of Annealing Lehr Equipment

Our tunnel-shaped annealing lehr is composed of steel shell, conveying roller and drive device, etc. It is divided into Zone A, B, C, D, E, F and G lengthways.
There is insulation layer in the shell of Zone A, B and C which are equipped with electrical heaters and radiation coolers; Zone D and E use sealed steel shell, and Zone E is installed with hot air circulation cooling device; Zone F and G are unenclosed construction, and Zone G is equipped with forced cooling device.

With heat insulation, the annealing equipment is transversely divided into zones for heating and cooling. This can effectively control the cooling speed and crosswise temperature difference of the glass ribbon. According to the requirements in terms of glass output, specifications and thickness, our quality annealing lehr is designed to offer optimized structure, subzones, and auxiliary equipment.

The annealing lehr is used to remove the inherent stress in glass and improve glass yield.
