| 20090321035 | CASTING ROLL FOR TWIN ROLL STRIP CASTER - Disclosed is a casting roll for a twin roll strip caster, and particularly, a casting roll for a twin roll strip caster, in which a continuous gas channel, for preventing the generation of dents in the surface of a strip when casting TWIP steel in order to improve the mechanical properties of the strip, including increasing the tensile strength and elongation, is formed in the surface of the casting roll, thus discharging gas mixed when the strip is cast, thereby preventing the generation of dents in the surface of the strip when casting the TWIP steel, in particular, a continuous gas channel is formed, thereby decreasing a conventional dent index and discouraging the generation of dents. | 12-31-2009 |
| 20100243193 | CASTING ROLL OF TWIN ROLL TYPE STRIP CASTER AND SURFACE TREATMENT METHOD THEREOF - The present invention provides a casting roll of a twin-roll strip caster, including: a nickel plating layer formed on an outer circumferential surface and an end surface of the casting roll; a nickel-boron alloy plating layer formed on the nickel plating layer located on the end surface of the casting roll; and a hard plating layer formed on the nickel plating layer located on the outer circumferential surface of the casting roll and an outer circumferential surface of the nickel-boron alloy plating layer located on the end surface of the casting roll. The present invention improves durability of the casting roll. | 09-30-2010 |

| 20120237390 | Martensitic Stainless Steel Produced by a Twin Roll Strip Casting Process and Method for Manufacturing Same - Provided is a martensitic stainless steel produced by a twin roll strip casting process and a method for manufacturing the same, wherein the hot rolled steel has superior crack resistance. The martensitic stainless hot rolled steel sheet comprises, by weight %, C:0.1 to 1.5%, Cr:12 to 15%, Ni:1% or lower, Ti:0.005 to 0.1%, and the balance Fe and unavoidably added impurities, and wherein a primary chrome carbide precipitated at a grain boundary is fragmented and refined. Provided is a high hardness martensitic stainless cold rolled steel sheet manufactured by annealing and cold rolling the hot rolled steel sheet, and a method for manufacturing the same. A twin roll strip casting process is applied, and grain boundary strengthening elements are added to prevent center segregation, crack and strip breakage during casting, thereby ensuring the stability of the casting process. | 09-20-2012 |
| 20120321501 | High-Carbon Martensitic Stainless Steel and Production Method Therefor - The present invention relates to a production method for high-carbon martensitic stainless steel as used in razorblades, knives and the like, which contains, as percentages by weight, 0.40 to 0.80% carbon and 11 to 16% chromium as main components. Provided is a production method for high-carbon martensitic stainless steel in a strip-casting device, wherein a stainless-steel thin sheet is cast by supplying a stainless molten steel containing, as percentages by weight, 0.40 to 0.80% carbon and from 11 to 16% chromium to a molten steel pool from a tundish via a nozzle, and the cast stainless-steel thin sheet is made into a hot-rolled annealed strip using in-line rollers to a rolling reduction of 5 to 40% immediately just after the casting so that the size of primary carbides within the microstructure of the hot-rolled annealed strip is 10 μm or less, and also provided is martensitic stainless steel produced by means of the production method. By reducing the size of the primary carbides formed in the cast structure and the hot-rolled sheet to 10 μm or less, the present invention produces high-carbon martensitic stainless steel having outstanding blade-end quality for use in cutting implements. | 12-20-2012 |
