ABSTRACT:
Process and apparatus for the production of metal blocks, castings or profile material (14) during which molten metal (S3) in a chill (K) is moved from a heating zone (HZ) into a cooling zone according to the solidification speed of the molten metal (S3) and during which cooling time hard material grains are continuously fed through the heating zone (HZ), preferably being electrical heated molten slag (12), the temperature of which is above the melting point of the hard material, into the molten metal (S3), the temperature of which is lower than the melting point of the hard material. The temperature of the molten slag, the height (h) of it and the height of the molten metal is controlled by the control device (ST) controlling the electrical current and dosing of the materials currents. Control methods and devices as well as material selections for matrix and doping materials are described.
