1700 ℃ frit furnace fused silica crucible bottom flow 1.6L 3L 5L 10L 18L spot

Usage:
This ceramic frit furnace is a funnel-shaped crucible placed inside the furnace, and the prepared frit material is directly poured into the crucible from above. There is a circular hole at the bottom of the crucible for material flow, and a long stopper is sealed and docked with the flow hole at the bottom of the crucible. Electrically heated, the stopper is in a downward pressure state (under its own gravity) during heating, and is in sealed contact with the flow hole to ensure no leakage during the heating process. After heating is completed, lift the stopper upwards and start feeding. On the contrary, if the stopper is released, the material flow will stop;
