Glass melting furnace GM 50

Crucible in glass melting furnace

The glass melting furnaces product line GM are used as day container. SiC rod heating in the furnace roof provide for fast heating times. A robust chamber insulation of refractory bricks in the bottom and non-classified fiber in the roof allows efficient working with low power consumption. Molten glass can be removed through the pneumatic lift-dopr out of the crucible (option) by means of a pipe.
