| 20090266506 | Method for Continuous Casting of a Metal with Improved Mechanical Strength and Product Obtained by Said Method - The invention concerns a method for continuous casting of a metal in the form of a hollow jet into a nozzle arranged between a pouring ladle or a tundish and a continuous casting ingot mold, said nozzle including in its upper part a dispensing member capable of deflecting at least part of the liquid metal reaching the nozzle inlet towards an inner wall of the nozzle before it penetrates into the ingot mold. Said method includes injecting into an inner volume of the hollow jet finely-divided solid material, characterized in that the finely-divided solid material comprises technical ceramic nanoparticles, of characteristic size less than 200 nm and preferably less than 100 nm. | 10-29-2009 |
| 20110277951 | REFRACTORY MATERIAL, CONTINUOUS CASTING NOZZLE USING THE REFRACTORY MATERIAL, PRODUCTION METHODS FOR THE CONTINUOUS CASTING NOZZLE, AND CONTINUOUS CASTING METHODS USING THE CONTINUOUS CASTING NOZZLE | 11-17-2011 |
| 20110308759 | HOT-TOP FOR CONTINUOUS CASTING AND METHOD OF CONTINUOUS CASTING - A hot-top is disclosed that continuously casts an ingot by pouring molten metal down into a cylindrical space in a continuous casting mold from a molten metal flow-down port. The inner shape of a flow-down port forming part corresponds to the inner shape of a cylindrical space forming part. The hot-top forms an annular groove about the molten metal flow-down port, and has a barrier between the annular groove and the flow-down port. | 12-22-2011 |
| 20140216679 | TAPERED HEARTH - A casting system and method. The casting system can include an energy source and a hearth, which can have a tapered cavity. The tapered cavity can have a first end portion and a second end portion, and the tapered cavity can narrow between the first and second end portions. Further, the tapered cavity can have an inlet at the first end portion that defines an inlet capacity, and one or more outlets at the second end portion that define an outlet capacity. Where the cavity has a single outlet, the outlet capacity can be less than the inlet capacity. Where the cavity has multiple outlets, the combined outlet capacity can match the inlet capacity. Further, the cross-sectional area of the tapered cavity near the inlet can be similar to the cross-sectional area of the inlet. | 08-07-2014 |
| 20150144291 | CONTINUOUS CASTING EQUIPMENT - Continuous casting equipment for a flow of liquid metal from a tundish into a mould is provided. The equipment includes a vertical duct disposed upstream of the mould with respect to the direction of travel of the liquid metal. The duct includes from upstream to downstream a refractory ring, a copper tube with an internal diameter D and a submerged entry nozzle. A dome is disposed inside the refractory ring and includes a sloped upper part, the upper part is defined so as to deflect the liquid metal coming from the tundish towards the inner walls of the vertical duct. The diameter D of the copper tube ranges between a minimum diameter equal to Q/3.75 and a maximum diameter equal to Q/1.25, where Q is the nominal liquid metal flow rate of the equipment and is between 200 and 800 kg/min and D is the diameter expressed in mm. | 05-28-2015 |
| 164489000 | Including flow stream deflection or other than vertical dispensing | 1 |
| 20080210401 | SUBMERGED ENTRY NOZZLE WITH INSTALLABLE PARTS - A partial SEN capable of having flow diverter parts installed therein, and a method of using the SEN in a continuous casting system are disclosed. The partial SEN includes a hollow distribution zone at a bottom portion of the SEN which is designed to allow the installation of at least two different types of flow diverter parts, one type of flow diverter parts for a first type of caster mold, and a second type of flow diverter parts for a second type of caster mold. The design of the flow diverter parts and the resulting angles achieved when the flow diverter parts are installed in the partial SEN are matched to a caster mold such that the flow characteristics of molten steel exiting the SEN into the caster mold during continuous casting operation are of a desired and optimal nature to prevent various types of casting defects. | 09-04-2008 |
