ABSTRACT:
A chill mold in a continuous casting apparatus consists of a cast material, which is shrunk onto the cast-in central chill tube as well as the chill tubes which spirally surround the same. Components of the apparatus are re-usable. This is accomplished by a primary and a secondary chill which are offset in the axial direction in relation to each other. Both chills are cooled by separate coolant circuits to their respective chill bodies. The ratio between the length in the continuous casting direction to the external and, respectively, the internal diameter of the primary chill is less than 70:100.
