Publication number: 20130248137Abstract: Embodiments of the invention relate to a method and apparatus for continuously casting a metal slab. The method involves continuously introducing molten metal into an inlet of a casting cavity defined between advancing casting surfaces, cooling the metal in the cavity to form a metal slab, and discharging the slab from the cavity through an outlet. The casting surfaces have an ability to remove heat from the metal but this ability is reduced, thus reducing heat flux, for at least one of the casting surfaces in a region of the cavity spaced from both the inlet and the outlet and extending transversely to the casting direction. This reduced ability to remove heat is relative to such ability of the casting surface in immediately adjacent upstream and downstream regions of the cavity. The apparatus may be a twin belt caster or other form of continuous caster modified to perform the method.Type: ApplicationFiled: February 12, 2013Publication date: September 26, 2013Inventors: Kevin Michael GATENBY, Edwin Stanley Luce

Publication number: 20100270000Abstract: With a continuous casting method for producing preliminary profiles, in particular double T preliminary profiles, the downwardly flowing cooling water is pushed out of the internal curve of the preliminary profile strand (3) via the profile flanges and discharged using water nozzles (21, 22) aligned substantially to the crossover from the bar (4) to the respective flange (5, 6) by means of the diverting water delivered via the water nozzles (21, 22). In this way the excessive cooling caused by downwardly running cooling water is largely avoided in the internal curve of the preliminary profile strand.Type: ApplicationFiled: March 5, 2010Publication date: October 28, 2010Applicant: SMS CONCAST AGInventors: Christian DRATVA, Klaus Von Eynatten

Patent number: 7798202Abstract: A broadside (100) for the broadside of a funnel mold for the casting of metal. Known broadsides of this kind have at least one groove-shaped cooling channel (110) in the backside (R) of the broadside. Adjacent the cooling channel (110) on the backside of the broadside, recesses (A1, . . . , A5) are provided as well as filler elements (140-1, . . . , -5) for the at least partial sealing of the recesses. In order to constructively simplify the broadside in view of the adjustment of a generally constant flow rate of a cooling medium through the cooling channel, it is proposed to design the recesses (A1, . . . , A5) in such a way, that they cross the cooling channel (110) diagonally to its longitudinal direction. Moreover, the recesses (A1, . . .Type: GrantFiled: August 30, 2006Date of Patent: September 21, 2010Assignee: SMS Siemag AktiengesellschaftInventors: Hans Streubel, Jörn Hoffmeister, Markus Reifferscheid, Gereon Fehlemann, Thomas Lamberti

Publication number: 20100059195Abstract: A continuous casting mold includes mold plates which enclose the casting cross section and in which cooling channels extend. The mold plates are connectable to a water box by screw elements which are formed by fastening bolts having a threaded shank which is screwable into fastening threads located in the mold plate. To achieve a uniform cooling in a continuous casting mold, the fastening threads are arranged such that their center longitudinal axes extend between two adjacent coolant channels of the plurality of cooling channels. The diameter of each threaded bore hole of the fastening threads is greater than the distance between the two adjacent cooling channels, and each bore hole of the fastening threads ends at a distance from the floor of the plurality of cooling channels to define the screw-in depth of the fastening bolts.Type: ApplicationFiled: October 18, 2007Publication date: March 11, 2010Applicant: SMS Schloemann-Strasse 4Inventors: Markus Reifferscheid, Albrecht Girgensohn

Publication number: 20100000704Abstract: An extrusion die (1) for the casting of liquid metals, in particular of liquid steel materials, has a heat flow density which is distributed non-homogenously over the die face. A homogenizing of the heat flow density can be obtained if the spacing between the hot side and the cooling duct base (=thickness (6) of the die wide side plate (2)) in the new state as a typical normal thickness (100%) is reduced by at least 20% to 80%, and a further reduction, obtained by means of reworking processes, of the thickness (6) which is initially reduced to 80% is restricted to 5 mm a final thickness (6a) by means of a final reworking process.Type: ApplicationFiled: July 31, 2007Publication date: January 7, 2010Inventors: Hans Streubel, Gereon Fehlemann

Publication number: 20090199993Abstract: The invention relates to a cooled continuous casting mold (1) for casting metal, especially steel, which has a casting format (GF) that is defined by respective two opposite broad faces (2, 3) and small faces (4, 5). The broad faces (2, 3) have a cooling area (6) which designed for the maximum casting width and comprises a plurality of cooling channels (7) extending in the direction of casting and being connected to a coolant circuit. The small faces (4, 5) can be adjusted to a predetermined casting format having a corresponding casting width. The aim of the invention is to provide a continuous casting mold for slab formats, especially thin slabs, which allows to adjust an even working end temperature of the broad sides and especially to reduce a considerable temperature drop in the neighborhood of the small faces while at the same time allowing to adjust different casting formats, especially smaller casting formats as compared to the maximum casting format.Type: ApplicationFiled: April 25, 2005Publication date: August 13, 2009Applicant: SMS DEMAG AGInventors: Hans Streubel, Jim Sears

Publication number: 20080283213Abstract: The invention provides a water-cooled mold for continuous casting. The mold comprises two water-cooled wide copper plates which are arranged opposite to each other in front and back direction and two water-cooled narrow copper plates which are arranged opposite to each other in left and right direction. The upper portion of the cavity of the mold is a sprue area and the lower portion of the cavity is a mold cavity area. The sprue area is gradually narrowed in the casting direction and smoothly transited into the mold cavity, corresponding to the shape of a slab to be cast. The inside surfaces of the water-cooled narrow copper plates are smooth planar surface. A portion of the inside surface of the water-cooled wide copper plates in the sprue area is a curved surface and a portion of the same in the mold cavity area is a planar surface. The curved surface portion and the planar surface portion form a continuous smooth surface.Type: ApplicationFiled: September 20, 2004Publication date: November 20, 2008Inventors: Rongjun Xu, Xiao Liu, Yongquan Li, Jian Cui
