It sets on lower furnace body, it can be in the ventilative gap between tubular furnace body and bottom plate and upper furnace body and lower furnace body, the company directly shelved
It connects relationship and is also more convenient disassembly.
For the heating element that voltage rating, rated power and shape are fixed, technological parameter includes heating time.
The structure of upper furnace body and lower furnace body
Due to crushing the presence of mica blank slow cooling insulating layer, it is easily separated between furnace body and mica melt, therefore upper furnace body
And/or lower furnace body can be integral type, can also be enclosed by cambered surface unit.Further, due to the top surface internal diameter of lower furnace body
Greater than bottom surface internal diameter, i.e., lower furnace body is inversed taper platform shape or side wall is the approximate inversed taper platform shape of drum surface, in order to reduce lifting operation,
Preferably, lower furnace body is enclosed by cambered surface unit, and further, lower furnace body is enclosed by two symmetrical cambered surface units, arc
