A temperature regulation device for the strip () produced in a continuous casting plant with ingot mold () comprising a pair of cooled, parallel, counter-rotating rolls ('), closed by two plates at the axial ends of the rolls, includes a pair of substantially rectangular panels () placed symmetrically under the plane of the rolls axis, with its longest dimension substantially parallel to the axis of the rolls. Ducts (&#x2032;) are provided which feed a series of jets () to spray cooling gas onto the strip surface ().

Strip temperature regulating device in a continuous metal strip casting plant

A continuous metal strip casting plant on which is mounted, at the casting location, a mobile ingot mould comprising two cylindrical metallic casting rolls in addition to other components, amongst which there are a tundish and/or under tundish and/or an unloader and/or lateral plates, respective preheating stations located in positions separated from the position of casting, and rotating arms located on a turret itself also placed on the casting plane to transfer the components from the casting line to their preheating stations.

A continuous casting method of a reduced height with a horizontal or almost horizontal oscillating crystallizer, whereby an immersed teeming nozzle teems molten metal into the crystallizer below the meniscus, regulation of the flow being obtained with regulation means corresponding to the formula: V.gtoreq.K.multidot..sqroot.2gh-2p/.rho., a pressure being kept within a tube portion of the teeming nozzle at least transiently which is correlated with the pressure surrounding the teeming nozzle itself and with the pressure acting on the meniscus of the molten metal in the crystallizer, the pressure within the tube portion of the teeming nozzle being such as will at least hinder the migration of gas from the exterior of the nozzle to the inside of the bore of the tube portion.

Casting method for a continuous casting machine of a reduced height with a horizontal or almost horizontal oscillatory crystallizer, whereby an immersed teeming nozzle teems molten metal into the crystallizer below the meniscus, regulation of the flow being obtained with regulation means. Pressure is kept within a tube portion of the teeming nozzle at least transiently which is related to the pressure surrounding the teeming nozzle itself and with the pressure acting on the meniscus of the molten metal in the crystallizer, the pressure within the tube portion of the teeming nozzle being such as will at least hinder the migration of gas from the exterior of the nozzle to the inside of the bore of the tube portion. An immersed teeming nozzle for a continuous casting machine of a reduce height is also disclosed. The teeming nozzle teems the metal below the meniscus of molten metal in an oscillatory crystallizer. A device to regulate the flow of the molten metal is included, the nozzle being suitable to perform the above method and comprising means at least to hinder a migration of gas from the exterior to the inside of the nozzle.

Continuous casting machine of a reduced height with immersed teeming

A process and apparatus for the continuous shearing of billets or bars of various shapes and sizes produced in a continuous casting plant wherein the shearing device moves in harmony with the billets is described. According to the process and as permitted by the apparatus, a first blade preferably the upper blade is caused to approach a billet and rest on it by means of hydraulic pressure working on cylinder/piston means, and thereafter a second blade positioned opposite the first blade is caused to move from supporting brackets to approach the billet and thereafter the blade caused to continue its course and cut into and shear the billet with the shears being supported substantially only by the billet during the shearing process. The device is relatively simple in design and is highly efficient.
