  • Continuous hot rolling method of metal blocks, as well as a metal block joining apparatus, a table roller for conveying the metal blocks, a poor joined portion removing apparatus and a metal block cooling apparatus which are used to carry out said method
    Patent number: 6152352
    Abstract: The invention comprises a continuous hot rolling method in which a rear end portion of a preceding metal block and a fore end portion of a succeeding metal block are cut and the metal blocks are joined to each other by heng and pressing followed by a finish rolling. A region of each metal block is restrained from a clamping position to the end portion thereof in order to prevent a change in level of the metal blocks in heating and pressing the piece. The end portions of the metal blocks can be thus prevented from deformation.
