According to the prior art, copper cooling plates (10) are fixed to the furnace armour plate (15) of metallurgical furnaces by elastically, gas tightly connecting the coolant pipes (13, 14) to said furnace armour plate (15) using compensators (16) and by welding. This prevents the fixture from being destroyed by heat-related alternating bending stresses. According to the invention, at least one fixed-point fixing element (11) is located near the coolant tubes (13, 14). As a result, at least some of the compensators (16) that are usually provided are no longer required and the costs are reduced.

Lors de la fixation de plaques de refroidissement (10) à la tôle de blindage (15) de fours métallurgiques, il convient de raccorder par soudage de façon élastique et étanche au gaz les tuyaux de réfrigérant (13, 14) à la tôle de blindage (15) à l'aide de compensateurs (16) pour éviter toute destruction du système de fixation provoquée par les contraintes de flexion alternée dues aux effets thermiques. Selon l'invention, on implante au moins un élément de fixation point fixe (11) à proximité des tuyaux de réfrigérant (13, 14). Ainsi au moins une partie des compensateurs (16) habituellement utilisés devient superflue, ce qui s'avère économique.
