Abstract

A method for the production of ingots, hollow or made of a plurality of metallic materials, of a first metallic material which includes the following phases: casting a first metallic material in liquid state into an ingot mould provided with a heat insulated bottom; allowing the aforesaid first metallic material to solidify only partially to obtain, in the centre of the ingot mould, a substantially cylindrical zone of said first material still in liquid state; discharge said substantially cylindrical zone of said first material still in liquid state, to form a substantially cylindrical cavity in the ingot. Subsequent cooling of the already solidified metallic material remaining in the ingot mould makes it possible to obtain an ingot equipped with a cylindrical through cavity perfectly coaxial to the ingot obtained. A second matallic material in liquid state may be cast inside said cavity to obtain a compound ingot.
