Abstract
A method for blasting calibrating a chill mold ( ) is provided. A calibrating mandrel is inserted into chill mold ( ), thereafter an explosive material is placed on the outer surface ( ) of chill mold ( ) and is ignited. The inner side ( ) of chill mold ( ) is pressed against the calibrating mandrel by the explosive force, and brought to the setpoint measure. In the mold wall ( ), chill mold ( ) has bores ( ) for cooling means and for measuring elements, which extend in the longitudinal direction (LR) of chill mold ( ) and exit at the end faces ( ) of mold wall ( ). Before the blasting calibration, the bores ( ) are filled up with a free-flowing material and tightly closed. The free-flowing material is preferably an incompressible fluid and/or a bulk material.
