Process and device for the production, in particular, of steel A B S T R A C T The invention concerns a process and a device for the production of a material, steel in particular, in which the different components are "interwoven" in such a way, that parts of the material in solid state are fed into a matrix, which is still in a liquid state for casting, and that the mix, respectively the conglome- rate, formed in this way, is made to freeze, and that afterwards the cast structure is processed by conver- sion and/or heat treatment. In this way it is possible, for example, to store particularly hard, i.e. extremely hard ingredients as those used, for example, in the hardest armour steel, in the form of particles, that is solid bodies in a softer, tougher matrix. In this way, on the one hand, the welding ability of the composite can be substantially improved and, on the other hand, it is possible to exclude the otherwise common cracking sensitivity of particularly hard special steels because the softer, tougher matrix prevents the expansion of the crack in the structure.
