Two persons are required to complete the lifting of the tempering furnace with one performing the operation and the other supervising the job. Never allow this job to be performed by one person! Never allow this job to be performed by non-professional personnel!
Emergency stop buttons are provided on the main operating station and on each operating control box at the scene. In case of an emergency, pressing down the emergency stop switch will halt the movement of all drives in the tempering furnace immediately, trigger the alarm, and shut off the main power supply to the drives and control circuit to ensure personal safety.

NiS (nickel sulfide) crystals contained in glass will undergo a phase change at 379℃, converting α-NiS crystalline form at high temperature into the β-NiS form at low temperature. The phase transition causes an increase in volume by 2%~4%, resulting in rough surface. If these impurities are located in the tensile stress zone, the increase in volume may cause spontaneous breakage of tempered glass.
ll moving parts should be either in the chamber or located behind protective barrier. Blowers shall be equipped with air-intake grid. The opening/closing part of the lifting device shall have safety pins. The lifting device in the bending chiller section shall have safety hook.
As the borosilicate fire-resistant glass has a high softening point and very low coefficient of thermal expansion, it creates a big challenge to tempering process.
Use an electronic micro compressor with level 1 accuracy to measure the air pressure of the chiller and take the average of the 4 measuring spots to compare with the maximum and minimum values.
