  • Patent number: 8051692
    Abstract: A shape detection device capable of detecting meandering of a strip with high accuracy and a method thereof. The device includes a plurality of split rolls provided in a width direction of a rolling material; a table which guides the rolling material and which is rotatably supported; a fixing member supported by the table; torque detectors for separately detecting loads acting on both ends of the split rolls when the rolling material comes in contact with the split roll as moments; supporting arms of which one end rotatably supports the split roll and the other end is supported by the fixing member through the torque detectors; a meandering amount computing unit for computing a meandering amount of the rolling material using the moments detected by the torque detectors, and a plate shape computing unit for computing a plate shape of the rolling material using the moments and the meandering amount.

  • Publication number: 20080169082
    Abstract: When a molten steel (106) is supplied into a moving mold defined by concave rolls (101, 102) and side checks (103, 104), the molten steel (106) is cooled by the surfaces of the rolls (surfaces except steps) to form solidified shells (111, 112). Both solidified shells (111, 112) are pressure bonded, and pulled out as a cast piece (113). A heat insulator (ceramic coating) has been applied to the circumferential surfaces of steps (101a, 101b, 102a, 102b) which are opposite end portions of the rolls. Thus, at these portions, heat dissipation does not proceed, and no solidified shells are formed. Hence, clearances are formed between the opposite ends of the solidified shells (111, 112) and the side checks (103, 104), and the solidified shells (111, 112) do not contact the side checks (103, 104), with the result that the wear of the side checks (103, 104) is prevented.
