A metal product, such as a steel strip or a mill roll, is cooled by spraying a coolant towards a surface of the product travelling along a given path, by means of cooling apparatus comprising two hollow caissons arranged one inside the other and rigidly connected together to constitute a unit. The caissons cool the strip contained within a tunnel. The method is applied to the product surface and extends across the path of the product surface. Each caisson has a plurality of holes in a wall which is to face the product surface, each hole of the outer caisson being paired with a coaxially aligned hole of the inner caisson. A coolant sprayer is fixed in each pair of holes. Preferably, the sprayers are supplied with air from the inner caisson and water from the outer caisson, the water being atomized by the air. The path containing the prouduct is enclosed within a tunnel wherein ends of the tunnel are enclosed by continuous curtains of water which contact the product and effectively seal the ends of the tunnel.
A method of cooling a rolled metal product in the form of a strip by means of a cooling installation comprising coolant sprayers disposed in a tunnel having ends which terminate in planar end walls provided with openings for receiving said strip therein, the method comprising the steps of passing the product horizontally through said tunnel, spraying a coolant onto the strip in the tunnel by means of said sprayers, and closing each end of the tunnel by projecting a continuous water curtain having an inner face which faces the tunnel opening so that said inner face contacts the planar surfaces of the end walls of the tunnel along the entire periphery of the openings above the strip said end wall neither projecting through the curtain nor being out of contact with it at any point above the strip.
