Processing after oxide firing Sandblasting with 125µm Aluminium Oxide
Cooling after ceramic firing
(Relexation cooling is recommended for lang span, bulky frameworks)
HeraCeram: Rapid cooling
At the end of the programm the firing platform is completely and firing tray with objects is removed emediately. The firing tray can cool next to the furnace on a fire-resistant tray.
Others: Slow cooling
Depending on programming of the furnace either slow cooling to the initial temperature can be performed for approx. 4 – 6 minutes or a tempering phase of 3 – 5 minutes can be set at approx. 800 °C (high-melting alloys) resp. at approx. 700 °C (low-melting alloys).
Rapid cooling can always be performed for oxide and opaque firings. (3)
