Abstract
A device and method for the plaining of glasses or glass-ceramics. The device is provided with a melting vat, at least two plaining containers serially connected after the outlet of the melting vat, and at least one of the plaining containers is built in accordance with the skull principle from a plurality of metal tubes comprising a cooling agent connection and a high-frequency device for inductively coupling high-frequency energy into the contents of the plaining container.
Claims18
A device for plaining glasses and glass-ceramics comprising:
- a melting vat for a glass melt;
- and
- at least two plaining containers serially connected to the output end of said melting vat to thereby receive the glass melt, at least one of the plaining containers being built up according to the skull principle, said at least one of the plaining containers including a plurality of metal tubes comprising, for their part, a cooling-agent connection and further including a high-frequency device for inductively coupling high-frequency energy into the contents of the plaining container.
A method for the plaining of glasses or glass-ceramics comprising the steps of:
- melting a plurality of substances together to thereby form a melt of glass;
- and then
- plaining in a plaining cascade consisting of two or more stages, the plaining taking place in at least one of these stages according to the skull principle with inductive heating of the melt, said inductive heating of the melt including radiating the melt with high-frequency energy.
