20090165987 | CONTINUOUS CASTING MACHINE AND METHOD USING MOLTEN MOLD FLUX - The present invention relates to a continuous casting machine and method using molten mold flux. The continuous casting machine includes a mold cover for covering an upper portion of a mold; a mold flux melting unit for melting mold flux to be supplied into the mold; and a mold flux delivery unit for supplying the mold with the molten mold flux melted in the mold flux melting unit, wherein the delivery unit includes an injection tube with one end connected to the mold flux melting unit and the other end positioned in the mold through the mold cover, and an injection tube heater for heating the injection tube. According to the present invention, since a slag bear continuous casting machine and method using molten mold flux is removed, a consumption of mold flux is greatly increased compared with a case of a conventional casting work, so that the friction between a mold and a solidified shell is reduced. As a result, an amount of scarfing of a cast piece is greatly reduced and no carbon pick-up occurs. | 07-02-2009 |
20090288799 | Method of Production of Ultralow Carbon Cast Slab - A method of production of an ultralow carbon cast slab characterized by adding Ti to molten steel decarburized to a carbon concentration of 0.01 mass % or less, further adding at least one of Ce, La, and Nd, and using an immersion nozzle to inject the above molten steel from a tundish to a casting mold for continuous casting while maintaining a flow rate of Ar gas blown from any location in a range from a tundish upper nozzle to discharge ports of said immersion nozzle at 3 Nl (normal liter)/min or less. | 11-26-2009 |

20150027656 | Method for preparing low-cost clean steel - A method for preparing low-cost clean steel includes steps of: preliminarily desulfurizing iron melt: preliminarily desulfurizing in an iron melt channel during blast furnace tapping and during iron folding in an iron folding room, adding a desulfurizing ball into the iron melt during the blast furnace tapping or the iron folding; dephosphorizing and controlling sulfur: dephosphorizing and controlling sulfur during converter steelmaking, in such a manner that P≦0.014% and S≦0.004% during tapping; rapidly dephosphorizing by slag-forming: rapidly dephosphorizing by slag-forming during converter tapping, at a converter end point, controlling a C content at 0.02˜0.10%, adding a dephosphorizing ball through an alloy chute during the converter tapping, blowing argon and stirring at the same time; purifying steel melt during RH refining: adding a purifying ball at a late stage of the RH refining when a vacuum degree is at 66.7˜500 Pa; and continuously casting with whole-process protection. | 01-29-2015 |
20160107226 | Method of Continuous Casting - A method of controlling the amount of hydrogen in steel for consistent heat transfer in continuous casting by adding a hydrocarbon to the molten metal. A heat of molten steel is formed in a ladle metallurgy furnace adapted for use in continuous casting. Then, a hydrocarbon is added to the molten metal in the ladle metallurgy furnace in an amount sufficient to increase hydrogen levels in the molten steel for casting. And finally, the molten steel with a desired level of hydrogen is delivered to a caster to continuously cast a steel product. | 04-21-2016 |
