  • Casting/rolling installation and method for dismantling and installing rolls in a reducing stand of the casting/rolling installation
    Patent number: 9700938
    Abstract: A casting/rolling installation for producing hot-rolled strip. In order to save investment costs for the roll changing device in a corresponding installation with two parallel casting lines, without a roll change taking place in the process in a less operationally reliable and more complicated manner, the roll changing device is configured in the form of a rotary table and arranged in the intermediate space between the two casting lines.
    Type: Grant

  • Method for the insertion of machine units into a production line
    Patent number: 7784316
    Abstract: The invention relates to a method for assembling and/or starting machine units in installations, such as machine beds (1) and/or roll stands (2), e.g. in an existing production line of a hot-rolling mill. In order to minimize especially the downtimes during assembly, the machine bed (1) is prefabricated and the required or cooperating machine units are prefabricated and preassembled or assembled on site next to the production line (3), whereupon said machine units are inserted into the production line (3) as a complete structural unit including the bed block (1) and allocated driving members, control elements, fastening elements or similar, pipes and cables required for operation, and additional pieces of equipment.
