Continuous casting apparatus, comprising a mold and a crystallizer for the continuous casting of a metal product. The mold is provided with primary cooling means using a cooling fluid and associated with the walls of the crystallizer. A plurality of cooling members is installed downstream of the mold to perform a secondary cooling of the product, said cooling members comprising a plurality of delivery nozzles configured to deliver a liquid for cooling the product.

Method for the continuous casting of a product (P), chosen from billets or blooms, along a curved casting line (18), the method providing to cast a liquid metal (M) in a crystallizer (11) having a tubular cavity (12) with an octagonal cross section.

A method for manufacturing a bonding wire includes: putting a surface layer metal of a bonding wire in a crucible having a die cooler provided at the lower part thereof and melting the same; putting a main component metal core of the bonding wire in a core guide located at the upper part of the die cooler of the crucible and heating the core guide to the melting point or below of the metal core; transferring the metal core toward the die cooler so as to allow the molten surface layer metal to be injected to the surface of the metal core; and manufacturing a 50 m to 350 m bonding wire from the cast wire precursor by using a drawing die.

An apparatus and a system including a casting pit; a mold including a reservoir and a cavity; a coolant feed operable to introduce a coolant to a periphery of a metal emerging from the mold cavity; an array of water vapor exhaust ports about at least the top periphery of the casting pit; a mechanism to introduce an inert fluid into the coolant feed. A method for a direct chill casting including, after detecting a bleed out, exhausting generated gas from the casting pit at a flow volume rate that is enhanced relative to a flow volume rate prior to detecting bleed out or run out; introducing an inert gas into the casting pit; and introducing an inert fluid into a coolant feed to the casting mold.

This disclosure concerns methods and apparatus for continuously casting thin strip where one or more expansion rings are positioned within at least one of a pair of casting rolls, and automatically measuring a thickness of the cast strip close to the first side edge of the strip using at least one sensor, and if the thickness measured is too thin, automatically decreasing the radial dimension of the expansion ring arranged in close proximity to the first side edge to cause the cylindrical tube to contract and increase the thickness of the cast strip during casting, and if the thickness measured indicates that the thickness of the cast strip is too thick, automatically increasing the radial dimension of the expansion ring arranged in close proximity to the first side edge to cause the cylindrical tube to expand and reduce the thickness of the cast strip during casting.

A method for operating a casting/rolling system and to a corresponding system for casting and rolling an endless strand material. The casting/rolling system comprises a strand casting machine and a rolling train arranged downstream of the strand casting machine. The method has the following step: controlling the drive for the rollers of the first roller frame of the rolling train by means of a drive control in response to a target value specification of the pass sequence model. Furthermore, the drive of the at least one strand guiding roller is controlled by a strand guiding roller drive control in response to a target value specification of the strand casting machine drive model.

Production plant of metal rods, casting machine, casting process and control method of at least three electromagnetic stirrer devices, wherein one provides at least one phase of switching between two operating configurations of the electromagnetic stirrer devices of which a first operating configuration with the generation of a rotating electromagnetic field inducing in the metallic material in the molten state a rotational motion and a second operating configuration with the generation of a linear electromagnetic field inducing in the metallic material in the molten state a linear motion.

A system for controlling the progress of the manufacture of at least one product by vertical semi-continuous direct chill casting, in particular from aluminium alloy, in a fixed mold, the control system includes a dummy bottom configured to form a movable lower bottom of the fixed mold and to carry the product during casting; a weighing cell, on which the dummy bottom is arranged to rest, the weighing cell being configured to take measurements representative of the mass of the product carried by the dummy bottom during casting; and a support of the dummy bottom, to which the weighing cell is linked, configured to lower the false bottom relative to the fixed mold, substantially in a vertical direction, during casting; and a processing unit connected to each weighing cell, and configured to process the measurements, and calculate the variation in the mass of the product over time.
