Abstract (en)

A method, for improving the capacity or quality of cooling in a gas blown cooling chamber or of an air blown cooling section of a heat treatment line for steel or aluminium and/or improving the quality of the products by reducing the vibrations generated by the cooling, uses a combination of the following parameters : (A) the possibility of the acceleration of the gas or air after impact on the strip in a direction essentially normal to the plane of the strip; (B) the augmentation of the volume confined between the strip and the blower without increasing the distance of blowing from the origin of the gas or air jets and the strip; (C) the channelling or guidance of all or part of the gas or air blowing towards the edges of the strip. An independent claim is also included for a device for putting this method into service.
