Abstract

<PICT:0900545/III/1> The diameter of a molten zone 4, passed through a silicon rod 1 by movement along the rod of a surrounding induction coil 5, is automatically maintained constant by upward or downward movement of an upper clamp 20 which is responsive to change in the current in coil 5 caused by change in the diameter of the zone 4 (see Group XXXV). The diameter of the rod may be varied by deliberately varying the current fed to the coil.
