摘要

The container (10) has a pipe (14) provided in a recess (12) that is opened at free end. An interstice (13) is provided between the pipe and the recess, and a cooling medium i.e. gas or liquid, is supplied in the pipe. The cooling medium is supplied into the interstice, and flows at the recess along a forming wall. The recess is aligned at vertical direction. The pipe projects into the recess, where cross-section of the pipe is adapted to cross-section of the recess. The cooling medium is fed in a closed cooling circuit.
