摘要： A template (1) for centering rollers at the foot of an ingot mold, the ingot mold being provided with a round section crystallizer into which the template can be inserted passing therethrough from a first end to a second end, the template comprising a round section tubular frame (5), defining a longitudinal axis (X) and having a plurality of longitudinal slots (6) arranged at an equal angular distance from one another; a plurality of longitudinal plates (7) configured so that each longitudinal plate is inserted into a respective longitudinal slot (6) and can move in radial direction through said respective longitudinal slot; at least one inflatable chamber (8, 8′), housed into the tubular frame (5) and at least partially covering the longitudinal extension of a frame stretch adapted to remain inside the crystallizer when the template is inserted into said crystallizer, said at least one inflatable chamber being adapted to expand so as to move said longitudinal plates outwards in radial direction to adhere them to the inner wall of the crystallizer.

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.

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.
