Abstract
An extrusion die (1) for the casting of liquid metals, in particular of liquid steel materials, has a heat flow density which is distributed non-homogenously over the die face. A homogenizing of the heat flow density can be obtained if the spacing between the hot side and the cooling duct base (=thickness (6) of the die wide side plate (2)) in the new state as a typical normal thickness (100%) is reduced by at least 20% to 80%, and a further reduction, obtained by means of reworking processes, of the thickness (6) which is initially reduced to 80% is restricted to 5 mm a final thickness (6a) by means of a final reworking process.
