Abstract
1. Method of cooling basically long or flat metallurgical products (1) having a substantially constant thickness with a view to minimizing the geometric distortions without altering the use properties, characterised in that substantially half the lateral surface is covered by a layer (2) which is insulating or a poorer conductor of heat than the product to be cooled (1) before the covered surface (2) of the product is brought into contact with an aqueous cooling medium (4).
