Patent number: 6945311Abstract: In a method for vertical continuous casting of a steel band, a strand (11) of a parallelogram-like cross section is cast at first in a revolving chill-mold (2) and is thereafter transferred from said initial cross section with completely solidified longitudinal edges (10) and liquid core into a band (1) with plane-parallel cross section, this occurring in such a way that an already solidified shell (9) of the strand (11) which becomes increasingly thicker by cooling is increasingly compressed in the casting direction in a forming device (4) without upsetting deformation of the completely solidified longitudinal edges (10). In order to provide advantageous conditions it is proposed that after the compression into a band (1) the strand (11) with a still liquid core (16) is guided during the complete solidification of the core merely in a forming gap with a constant width corresponding to the thickness of the completely solidified longitudinal edges (10) and is calibrated in this process.Type: GrantFiled: May 7, 2002Date of Patent: September 20, 2005Inventor: Anton Hulek

Patent number: 5385199Abstract: In a continuous casting apparatus having a pair of moving mold walls between which is defined a molten metal reservoir, the surface of molten metal is covered with an insulating member disposed within the molten metal reservoir. Projecting from opposite sides of the insulating member at locations adjacent the moving mold walls and toward the direction of movement of the mold walls are immersion walls which are immersed into the molten metal. The horizontal distance between the surface of each immersion wall and the surface of the moving mold wall closer thereto is more than 3 mm but not more than 10 mm. The molten metal within the gap between the moving mold wall and the immersion wall steadily flows outward following the movement of the mold wall, and accordingly fresh molten metal flows into the gap and circulates within the gap without stagnation. Therefore, even if slag flows into the gap, the slag positively flows outward without becoming accummulated therein.Type: GrantFiled: June 1, 1994Date of Patent: January 31, 1995Assignee: Hitachi Zosen CorporationInventor: Haruo Sakaguchi

Patent number: 5311923Abstract: A continuous block caster is provided with a mold block assembly having an internal anchor pin which is insulated. One end of a support pin, many of which are used to support each block, is threaded into the anchor pin, the other end is demountably secured in a fastening member in turn fastened to a carriage block. All the fastening members except only one at the center, are y- or x-y slides, so termed because they permit lateral movement of the support pin. A stepped lock-down key which provides a camming means, allows an entire mold block assembly and supporting pin assembly to be connected and disconnected quickly from the carriage block by rotating the key. Insulating the support pin in this manner allows the planarity of a casting face to be maintained in a lateral plane within 5 mils (127 micrometers) of vertical movement. Such limited distortion does not adversely affect the planarity of the upper and lower faces of the cast slab.Type: GrantFiled: November 4, 1991Date of Patent: May 17, 1994Assignee: Aluminum Company of AmericaInventors: John W.

Patent number: 5133401Abstract: A continuous casting machine ("block caster") is provided with chain-wise interlinking of mold block assemblies. Such chain-wise interlinking maintains the mold block assemblies essentially contiguous and is essential to provide operation of a continuous casting machine essentially free of mechanical noise. Each mold block assembly is elastically independently hinged by dual parallel hingepins, spaced-apart in the casting direction (x-axis), as the mold block assembly is carried between opposed, transversely (y-axis) spaced-apart guide rails of each carriage track. The elastic hinge means compensates for variation in block-to-block (centerline) distance caused by kinematic phenomena, including thermally induced variations in the dimensions of individual blocks as a function of their position in each track during operation. Guide rollers guided in generally horizontal guide roller-ways are afforded no measurable tolerance relative to their vertical displacement, when the roller-ways are off-set.Type: GrantFiled: March 25, 1991Date of Patent: July 28, 1992Assignee: Aluminum Company of AmericaInventors: Lawrence W.

Patent number: 4770228Abstract: A metal casting device employs a number of pairs of mold members which can be opened or closed with respect to each other. The mold chamber pairs cooperate, in their closed state, to form a linear mold chamber. In order to compensate for shrinkage as the metal cools, the mold member pairs are movably supported by an endless chain, with the pairs of cooperating mold members being provided with contact faces having the same angle of inclination. Each mold member pair is also equipped with supporting rollers with which the associated mold chamber section can be closed or opened, as required.Type: GrantFiled: December 7, 1987Date of Patent: September 13, 1988Assignee: Fried.

Patent number: RE38555Abstract: A continuous chain caster has upper and lower mold assemblies comprising endless belts and chains traveling at synchronized speeds. The mold assemblies meet to form a mold channel which is filled with molten metal from a headbox and feed tip. As the molten metal passes through the mold channel, the metal solidifies into the shape of the mold channel. Each belt is positioned outside the corresponding chain so that the smooth surface of the belt defines the surface of the mold channel thereby preventing the formation of fins between mold blocks which make up the chain, protecting the chain blocks, and neutralizing deformations in the chain blocks. The upper and lower blocks of the chains have protrusions at opposite ends which engage the opposing blocks to form the sides of the mold channel. By sliding the chains relative to each other, the width of the mold channel is adjustable.Type: GrantFiled: September 25, 2001Date of Patent: July 13, 2004Assignees: Hunter Douglas Industries, B.V., Fata Hunter, Inc.Inventors: Curt Braun, Christopher A.
