Abstract
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.
