Definitions

  • the continuously casted billets are of much larger cross section than is capable of being rolled by a 're-rolling' mill.
  • continuous casting machines producing "bloom" strands having a cross section of greater than 150mm by 150mm square, and up to 400mm by 400mm square (typically 240mm by 240mm square or in the case of a tube continuous casting machine, 250mm round) are now commonplace at the larger steel producing facilities. These blooms are larger than the typical maximum size billet of 150mm by 150mm square that can be rolled by the re-rolling mills described above.
  • the drive mechanism and/or motor for the or each cantilever rolling mill stand is connected to the respective cantilever rolling mill stand by respective long shafts arranged so as to distance the drive mechanism and/or motor from the hot blooms.
  • FIG. 1 illustrates an apparatus and method of operation thereof for in-line rolling of billets from continuously cast blooms in accordance with an embodiment of aspects of the present invention.
  • the second cantilevered rolling mill stand 152 of each rolling mill is drawn with the drive mechanism and motor 156 and the housing 158 below the strands 118 at floor level.
  • the rolling mills 150 can be arranged such that the drive mechanism and motor 156 and the housing 158 of the cantilevered rolling mill stands 152 are never positioned underneath the strands 118 by, for example, positioning certain components above floor level.
