Abstract
The feed line (7) and the return line (8) are combined to a single current supply line (6) at one end of the coil which leads to the first turn sections connected to the opposite end of the coil. Second turn sections running back to the supply line (6) are radially opposed from respective first turn sections.
Claims6
An electrical power supply coil for the ceramic free outlet of a melting pot, said coil comprising
- a top end, a bottom end, and a central axis extending between said ends,
- a coaxial power supply cable which provides a feed line and a return line at one of said top and bottom ends,
- a plurality of electrically continuous first turn sections at successive levels between said ends, said first turn sections being supplied by said feed line,
- connecting sections connecting said first turn sections between said successive levels,
- a like plurality of electrically continuous second turn sections at successive levels between said ends, each second turn section being radially opposed to one of said first turn sections, said second turn sections being connected to said first turn sections only at the other of said first and second ends and connected to said return line at said one end, and
- connecting sections connecting said second turn sections between said successive levels.
