Abstract: A method of cooling of a flat metal product having a broad face and a temperature upper to 400° C., wherein the metal product is put in contact with a fluidized bed of solid particles, the solid particles having a direction of circulation (D) and capturing the heat released by the metal product and transferring the captured heat to a transfer medium wherein the metal product is put in contact with the solid particles so that its broad face is parallel to the direction (D) of circulation of the solid particles, a thermal cooling path of the metal product is defined, considering the product parameters of the metal product, a gas is injected for fluidizing the solid particles in a bubbling regime, the injection flow rate of said gas being controlled to match the defined cooling path of the metal product.
