  • Patent number: 7980291
    Abstract: An arrangement for maintaining the warmth of slabs which exit from a continuous casting installation and which can be transported on a roller table for further processing. In order to optimize the thermal balance between the continuous casting installation and the hot rolling mill, a supporting part is provided for receiving a slab, which supporting part can be placed on the roller table and transported thereon, and an insulating box which can be placed upon the supporting part and which substantially encloses the latter.

  • Publication number: 20110114282
    Abstract: The invention is based on the object of creating a strand guide roller being configured in a modular manner, which can be retrofitted to different stand casting widths without any substantial effort, and which has a cooling effect starting from the core regions of the roller extending up to the region near the surface thereof, thereby improving the life of the strand guide roller and achieving a comparatively cost-effective maintenance. The problem is solved according to the invention in that a first centrally disposed, axially extending flow channel (11 and a second centrally disposed, axially extending flow channel (12) are present in each roller module (2, 3, 4), that flow channels (15, 16) are disposed in the region near the surface of each roller module (2, 3, 4), and that connecting channels (17) connect the respective flow channels (15) to the first separate flow channel (11), and that connecting channels (18) connect the respective flow channels (16) to the separate second flow channel (12).

  • Publication number: 20100230067
    Abstract: The invention is directed to an arrangement for maintaining the warmth of slabs (3) which exit from a continuous casting installation and which can be transported on a roller table (1) for further processing. In order to optimize the thermal balance between the continuous casting installation and the hot rolling mill, it is proposed to provide a supporting part (2) for receiving a slab (3), which supporting part (2) can be placed on the roller table (1) and transported thereon, and an insulating box (4) which can be placed upon the supporting part (2) and which substantially encloses the latter.

  • Publication number: 20090107648
    Abstract: The invention relates to a roll (1) for metal production and/or metal processing, in particular a continuous casting roll, which has a roll parent body (2) of metal and a coating (3) of wear-resistant material applied to said roll parent body (2). In order to make the roll, in particular the continuous casting roll, especially wear-resistant, the invention provides for the coating (3) to have electrolytically applied nickel, wherein the surface (4) of the coating (3) forms the working surface of the roll (1). Furthermore, the invention relates to a method of producing a roll (1) for metal production and/or metal processing, in particular a continuous casting roll.

  • Patent number: 7497244
    Abstract: The invention relates to a device for supporting and oscillating a continuous casting mold (1) for continuously casting molten metals, particularly molten metal materials, comprising: guide elements (4) symmetrically arranged on both sides of the central longitudinal axis (2) of the casting; fixed supporting parts (5), and; a continuous casting mold (1) supported on paired oscillating devices (6). The inventive device facilitates the accessibility to individual modules for maintaining and/or eliminating damages. To this end, a module (7) that, itself, can be removed, is formed from paired bearing blocks (9) with guide elements (4) and with a supporting casing (7a) connected to said bearing blocks. The module is placed upon a stationary submodule (7b) and detachably connected thereto.

  • Patent number: 6484546
    Abstract: A strip deflection roller, especially a tension measuring roller or looper roller for matching tension in rolling stock between two roll stands for hot rolling and cold rolling of strip. The strip deflection roller includes at least five adjacent disks which are mounted on a common eccentric shaft so as to be freely rotatable independently. At most two of the disks are mounted concentric to the axis of rotation of the eccentric shaft, and the height positions of the rest of the disks can be changed for influencing the profile and regulating the flatness of the strip guided over the strip deflection roller by rotating the eccentric shaft.
