摘要： An electromagnetic device for laterally containing a liquid metal, having a first electrical conductivity, at one open side end of a passage defined between two counter-rotating casting rolls, at least the surfaces of which are made of a ferromagnetic material, said device comprising a magnetic yoke made of a further ferromagnetic material having a second electrical conductivity either lower than or equal to said first electrical conductivity of the liquid metal and ending with two mutually proximal wedge-shaped ends, said wedge-shaped ends having respective inner surfaces, facing each other and defining a gap, and respective outer surfaces, arranged one on one side and the other on the other side with respect to a plane lying in said gap and shaped so as to be able to insert both said wedge-shaped ends at least partially between the two casting rolls; at least one coil wound on at least one stretch of the magnetic yoke and adapted to be supplied by electric current; at least one plate, made of a material having a third electrical conductivity either greater than or equal to said first electrical conductivity, said at least one plate being inserted in said gap so as to shield said inner surfaces with respect to each other.

摘要： A containment system for laterally containing a liquid metal material or liquid metal alloy at an open side end of a passage defined between two casting members, said system comprising
a pneumatic device ending with a hollow end element adapted to be arranged close to said open side end of the passage,
wherein said hollow end element defines a chamber therein,
wherein said pneumatic device is adapted to feed a compressed aeriform substance into said chamber,
and wherein said hollow end element is provided with at least one blowing face for blowing said compressed aeriform substance from the chamber towards a side containment zone for said liquid metal.-
