摘要： Continuously cooling a rolled metal product emerging from the last stand of a rolling mill by spraying a liquid coolant through at least one outlet orifice of at least one hollow housing onto a rolled product vertically downwardly in the form of a compact jet of liquid which does not include any gaseous constituents and all the molecules of which are at the same speed in a given cross-section transverse to the direction of the jet.

摘要： In a secondary cooling zone below a continuous casting mold there is provided one or more chambers having an anterior wall with apertures facing the continuously cast metal product at a given distance from the surface of the product. Pressurized cooling liquid is supplied to the apertures to form a continuous layer of pressurized cooling liquid flowing in the direction of travel of the product.

摘要： A cooling apparatus for a cylindrical member in linear motion comprises a tubular conduit through which the cylindrical member passes axially, an envelope surrounding the tubular conduit and forming therewith an annular chamber therebetween closed at its ends by an upstream wall and a downstream wall, respectively, cooling agent being introduced into the annular chamber. The tubular conduit is pierced radially by a plurality of a straight passages providing communication between the annular chamber and the internal space in the tubular conduit. These passages are located in planes perpendicular to and axially spaced along the longitudinal axis of the tubular conduit and are equally circumferentially spaced within each plane and angularly displaced with respect to the passages in the adjacent planes. Cooling agent passes through the passages radially inwardly and is drained from the internal space of the tubular conduit.

摘要： A steel section 6 to 40 mm thick, emerging from a hot rolling mill at 1000.degree. to 800.degree. C. is surface quenched for 2 to 6 seconds at a cooling rate of the order of 1.5 to 5 MW/m.sup.2. During subsequent self-tempering of the quenched surface by heat from the remainder, the section tends to an equalization temperature of 500.degree. to 700.degree. C.

摘要： 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.
