ABSTRACT:
A system that employs air to directly cool heat-accessible metallurgical vessels that are provided with separate annular supports, characterized in that air channels (6) are positioned on the outside of the annular support (5) with a number of air-injection pipes (7) distributed along the circumference and extending radially from the channels to the inner wall of the annular support, whereby outlets (8) slope up into the gap (3) between the annular support and the outer wall (1) of the metallurgical vessel, in that air is injected into the cooling system through one or both load-bearing connectors (4), and in that the difference in pressure within the system is less than 2000 mm H.sub.2 O and the air travels at less than 25 m/sec.
