A flat glass tempering furnace is a specialized industrial machine used to heat and cool flat glass sheets in a controlled manner, enhancing their strength and safety properties. Here’s an overview of the process and key features:
Overview of the Tempering Process
Heating:
The glass sheets are heated to a temperature of approximately 620-680 degrees Celsius (1148-1256 degrees Fahrenheit), which is near the glass’s softening point.
The heating is done uniformly to ensure even temperature distribution across the entire glass sheet.
Quenching:
After reaching the desired temperature, the glass is rapidly cooled using high-pressure air jets.
The rapid cooling causes the surface of the glass to solidify quickly while the interior remains slightly warmer and more fluid for a short time.
This process creates compressive stresses on the surface and tensile stresses in the interior, giving the tempered glass its strength.
Key Features of a Flat Glass Tempering Furnace
Heating Section:
Usually consists of electric heating elements or gas burners.
Equipped with precise temperature control systems to maintain uniform heating.
Quenching Section:
Comprises a series of air nozzles that blow high-pressure air onto the heated glass.
Designed to cool the glass rapidly and uniformly.
