Glass melting furnace

The frit furnace (ceramic, glass (powder), enamel glaze, etc.) is a vertical resistance furnace. Its working method is to place a crucible in the furnace, and put the prepared frit material directly into the crucible (glass industry crucibles), heated by electricity, when the temperature When the temperature rises to the specified temperature, the frit will be in a molten state, and it will automatically flow into the lower container through the small hole below (there is a flow hole at the bottom of the crucible. Main features of frit furnace (for ceramic glass): A funnel-type crucible is placed in the furnace, and the prepared frit is directly put into the crucible from the top. There is a circular hole at the bottom of the crucible. The long stopper is tightly connected to the flow hole at the bottom of the crucible. Electric heating, the stopper rod is in a downward pressure state (under its own gravity) during heating, and is in sealing contact with the flow hole to ensure that the heating process does not leak. After the heating is completed, pull the stopper up to start discharging. Conversely, if you release the stopper, stop Flow material; when the temperature rises to the specified temperature, the frit will be in a molten state, and it will automatically flow into the lower container from the flow material hole below (there is a hole at the bottom of the crucible);
