Document Type and Number:
Japanese Patent JP2884246
Kind Code:
B2
Abstract:
The invention relates to a refractory nozzle between a vessel containing a metal melt and a withdrawal device for the metal melt, in particular a refractory outlet for molten steel.
To avoid the metal melt freezing in and to avoid deposits of constituents of the metal melt on the inner surface (2) of the wall of the outlet, the invention essentially proposes that the inner wall (1) of the outlet be composed completely or partially of a ceramic material which is electrically conductive at least at the liquidus temperature of the metal melt and can be inductively heated by means of an induction coil (4), or contains such a material. The invention also relates to the particular design of an induction coil (4) which is economic to use for this purpose or, indeed, in another context.
