Smicon FTA 1500U-6L fumigation / gassing system In a fumigation, a room is flooded with a poisonous gas to fight pests / bacteria. Because they are toxic gases, special safety measures are required. Fumigations are common in the storage of organic materials (eg grain storage, in warehouses of harbors, silos, mills), in addition, in churches to control the woodworm. It is a device which is used for the disinfection of rooms. Formaldehyde is boiled on the left-hand cooking plate and placed in a stream of air in a room together with condensed water (right hearth) to kill all the bacteria.

oven 700 Uterna Europe 80KW 700 Celsius Ziel des Spannungsarmglühens schoenheider ist die Reduzierung von Eigenspannungen im Material. Solche Spannungen entstehen zum Beispiel durch Gefügeumwandlungen, Kaltverformung und durch spanende Bearbeitung. Wichtig für ein gutes Ergebnis ist nicht nur die richtige buerstlein Temperatur, sondern auch eine umsichtige Abkühlung. Nur so lässt sich eine erneute Spannungsbildung vermeiden. Typischerweise findet das Spannungsarmglühen bei Temperaturen um 600 °C (bei zuvor vergüteten Bauteilen jedoch 30-50 °C unter der letzten Anlasstemperatur) statt. Die Wärmebehandlung ist das häufigste Veredelungsverfahren, mit dem die Eigenschaften der Stähle gezielt verändert und ihre optimalen Gebrauchseigenschaften für den jeweiligen Einsatzzweck herbeigeführt werden.
