| 20080257524 | Delivery Device and Method for Using the Same - Discharge device for discharging liquid steel into a roller crystallizer for the continuous casting of thin strip capable of reducing turbulence at the meniscus to a minimum so as to eliminate the relative defects on the cast strip by passing the steel between two crystallizer rollers. A relative casting process is also described, said process providing for particular expedients for improving the steel feeding from the tundish to the crystallizer. Advantageously, the feeding of guided steel jet streams inside the nozzle, or delivery nozzle, eliminates the disturbance at the meniscus caused by the air bubbles which form when free-falling jet streams come into contact with the air, as occurs in the known devices and plants. | 10-23-2008 |

| 20090173470 | PROCESS FOR MANUFACTURING CAST ALUMINUM ALLOY PLATE - A twin-roll continuous casting method that controls occurrence of casting defects in a center part of plate thickness, for Al—Mg series aluminum alloy, a material featuring a wide temperature range for solid and liquid phases coexistence. In the method manufacturing an Al—Mg series aluminum alloy cast plate, the plate contains Mg in a predetermined amount and has a relatively thick plate size, while casting is performed by a twin-roll type continuous casting method. Twin rolls have a roll diameter, and the rolls have a circumferential velocity. The circumferential length from points where molten metal starts contact with the rolls to kiss points is a solidification distance, and the roll gap at the kiss points is equal to the thickness of the cast plate. Specific relations among the above factors are maintained, and the continuous casting operation is carried out while satisfying such relations. | 07-09-2009 |
| 20100101752 | OPERATING METHOD FOR TWIN-ROLL CASTING MACHINE, AND SIDE WEIR SUPPORTING DEVICE - Intended is to acquire a strip with less thickness even if arcuate wear steps are formed on side weirs. | 04-29-2010 |
| 20110067835 | METHOD AND APPARATUS FOR CONTROLLING STRIP TEMPERATURE REBOUND IN CAST STRIP - During continuously casting metal strip, delivering molten metal supported on the casting surfaces of the casting rolls, and counter rotating the casting rolls to form metal shells on the casting surfaces brought together at the nip to deliver cast strip downwardly with a controlled amount of mushy material between the metal shells, determining at a reference location downstream from the nip a target temperature for the cast strip corresponding to a desired amount of mushy material between the metal shells of the cast strip, sensing the temperature of the cast strip cast downstream from the nip at the reference location and producing a sensor signal corresponding to the sensed temperature, and causing an actuator to vary the gap at the nip between the casting rolls in response to the sensor signal received from the sensor and processed to determine the temperature difference between the sensed temperature and the target temperature. | 03-24-2011 |
| 20120103555 | ULTRA-THIN SLAB OR THICK-STRIP CASTING - A system of twin-roll casting an ultra-thin slab or thick-strip of metal with a liquid core still present inside the hollow shell of the casting as it exits the nip of the opposing counter rotating casting rolls. The wide sides of the cast shell are formed against a recessed casting surface on each roll and the narrow end walls of the shell are formed against the tapered ends of the recessed area so one half of the narrow end wall is formed on each roll and the two halves are joined together at the nip to form the full perimeter of the metal casting. A liquid-cooled copper mold liner provides continued support to each of the four sides of the casting below the twin-rolls and contact with those chilled copper mold liners continues to remove heat from the liquid core of the casting enabling the shell to continue growing in thickness. As the casting exits the mold it will be of adequate thickness to pass through opposing pairs of support rolls below the mold without bulging where water sprays can provide the additional cooling needed for final and complete solidification. A variation of this system uses one or more separating dams to cast different metals or different alloys of the same metal to integrally cast a dual-layer or multi-layer ultra-thin slab or thick strip of metal with a thin metal layer on one or both of the wide and narrow end casting surfaces. | 05-03-2012 |
| 20130248136 | IN-SITU HOMOGENIZATION OF DC CAST METALS WITH ADDITIONAL QUENCH - The invention relates to a method and apparatus for direct chill casting ingots with in-situ homogenization. Large particles of eutectic material may form in the solid ingot and the metal may exhibit macrosegregation of alloying components, especially when large ingots are cast in this way. This can be alleviated by applying a first liquid coolant to the ingot emerging from the mold, removing the first liquid coolant at a certain distance along the ingot by means of a wiper, and then applying a second liquid coolant to perform a quench at a greater distance along the ingot. The quench raises the level of the molten sump in the ingot, which helps to overcome the indicated problems, without affecting the desired temperature rebound of the ingot shell (usually at least 425° C. (797° F.)) for a time effective to cause in-situ homogenization. | 09-26-2013 |
| 20160158833 | PULLING-UP-TYPE CONTINUOUS CASTING METHOD - A pulling-up-type continuous casting method according to an aspect of the present disclosure is a pulling-up-type continuous casing method for pulling up molten metal held in a holding furnace by using a starter. When the starter is accelerated to a predetermined pulling-up speed at a start of casting, the pulling-up-type continuous casting method includes a first acceleration section in which the starter is accelerated from a standstill state to a first speed at a first acceleration, a second acceleration section in which the starter is accelerated from the first speed to a second speed at a second acceleration, and a constant speed section in which the starter is pulled up at the first speed, the constant speed section being positioned between the first and second acceleration sections. | 06-09-2016 |
