Hot blast cupola

Continuous, energetically optimized melting

Hot-blast cupola furnaces are convincing for ow melting costs due to the continuous and energetically optimized counterflow melting with tapping temperatures of 1,520 °C, high metallurgical flexibility (carburizing, alloying and use of cheap scrap), an efficient heat balance through heat recovery - e.g. by the hot blast generation to 600 °C, heating of foreign processes and buildings.

Küttner has built more than 450 cupola furnaces of different types worldwide with melt loads of up to 100 t/h.

Besondere Merkmale

The cupola iron is superior in quality and suitable for the production of GJL, GJS and GJV varieties.
