How to produce clay roof tiles (Part three)
6. Firing
For Clay roof tiles that are produced with a ceramic surface (engobe or glaze), this is burned in during firing
process.
The firing of the tiles at a temperature of 900 to 1200°C in a tunnel kiln is the final part of the production
process. After this step, the finished product is available for use. After firing, brick products are
nonflammable and fire-safe for ever. Kiln and firing technologies as well as air stream systems have reduced the
required firing time by up to two-thirds. This has created enormous advantages: a 50% decrease in the use of
primary energy over the past ten years, up to 90% less emissions through thermal post-combustion equipment,
optimized product quality and a substantial increase in capacity.
7. Packaging
The fired tiles are loaded onto palettes with automatic equipment, and normally enclosed with pallet foils.
