A crystallizer for continuous casting including a tubular body formed of a first and a second tubular element both monolithic each made in one single piece in a metal alloy and mounted coaxial, the first inside the second with radial play, one of the first and second tubular element being provided with one or more grooves opened towards the other tubular element; the first and second tubular element are mechanically coupled together, by plastic deformation by means of drawing between a die and a mandrel appropriately shaped, in such a manner to eliminate the radial play, so that the tubular body is monolithic and the grooves are radially closed, forming conduits in the tubular body configured to serve as cooling conduits and/or housing reinforcement bars.

The invention relates to a method for producing a casting mold as well as to a casting mold (10), in particular a continuous casting mold or similar. Said casting mold is made of a material which is essentially made of carbon and the casting mold is coated with pyrolytic carbon and/or boron nitride.

Methods and apparatus for forming high aspect ratio metallic glass objects, including metallic glass sheets and tubes, by a melt deposition process are provided. In some methods and apparatus a molten alloy is deposited inside a channel formed by two substrates moving relative to each other, and shaped and quenched by conduction to the substrates in a manner that enables the molten alloy to vitrify without undergoing substantial shear flow.

A continuous casting mold including a water-cooled copper mold having a mold copper plate including an inner wall surface, recessed portions disposed partially or entirely in a region of the inner wall surface of the water-cooled copper mold from at least a position located at a meniscus to a position located 20 mm lower than the meniscus, and material-filled layers disposed in the recessed portions with a metal or nonmetal having a thermal conductivity different from that of the mold copper plate of the water-cooled copper mold. A shape of each of the recessed portions at a surface of the mold copper plate includes a curved surface.
