Automatic control of operating conditions in the annealing lehr of a thermally polished glass line
- 25 Downloads
A computerzed system was developed and integrated into a thermally polished glass line to control the temperature parameters in its annealing lehr. This served to optimize the annealing of Metelitsa glass, to cut down to 2 h the time required for the lehr to attain steady-state operation, and to raise the glass yield to 0.75. Suitable prompts were devised for operators in charge of the annealing operation, and the optimal format was found for the presentation of information about the on-going process.
