Definitions
- Document JP-A-02075450 shows a closure plate essentially constituted by a refractory material for its functional part and supported by a metal plate.
- Document JP-A-01249243 shows a thick copper closure plate covered with deposits of nickel and chromium. Hitherto various means have been proposed to avoid this undesirable solidification of the liquid metal on the small faces, in particular the use of magnetic inductors arranged near the latter and intended to heat the liquid metal.
- the penetration depth is around 7 mm for a frequency of 50 Hertz.
- a small face formed by a metal plate, in particular made of copper, the thickness of which is clearly less than the penetration depth of the magnetic field can be considered transparent, at least partially, to the magnetic field. This allows heating of the liquid metal in contact with the small face, eddy currents also being induced in the liquid metal and developing a Joule effect.
