Definitions

  • the invention relates to a system for producing a hot-rolled product from a Cast strand with two or more continuous casting machines and one assigned to them Rolling plant with guide sections for transporting one from the cast strand separated strand piece, with in at least one line of the rolling mill and in one this non-aligned line of a continuous casting machine each a swiveling or laterally movable guide section is provided, which is aligned in one position can be aligned with each other.
  • a strand piece is diverted from the line one of the Continuous casting machines in the line of the rolling mill with the help of two as swivel furnaces trained guide sections, with a swivel oven in the line of Continuous casting machine and the second swivel furnace is arranged in the line of the rolling mill, and both swivel furnaces can be aligned in alignment with the line in a swivel position are, in which they are arranged, and in a second pivot position with each other in straight connection can be brought upright, the free ends of the two Connect swivel ovens to each other.
  • a very similar method and a device for this are known from EP-B 0 593 002 known, here also two pivoting or laterally movable furnaces are provided, to redirect a strand part from a line of a continuous casting machine into the line serve the rolling mill.
  • the two movable ovens open flush to each other, but the conveying direction of the strand part is reversed twice, i.e. that when conveying the strand piece from one line to the other the strand piece is in opposite direction to the conveying direction of the continuous casting machine and the rolling mill emotional.
  • a disadvantage of these known systems is the unconditional temporal coupling of the two pivoting or moving ovens, as these are aligned with each other need to redirect a strand piece. This results in a temporal coupling of the Lines of the continuous casting machines and the line of the rolling mill. During the rerouting it is namely not possible, the line from or into which the strand piece is to be conveyed, to keep operating, i.e. an interruption of operations is absolutely necessary here the strand piece to be diverted has moved completely out of a line or in the line in which it should be brought in, is located and promoted.
  • the invention aims at avoiding these disadvantages and difficulties and presents itself the task of creating a system of the type described at the beginning, which involves rolling of strand pieces of two or more casting machines with a single rolling mill allow, but the casting and rolling operations are largely flexible Ability to decouple a temporal dependency when redirecting of a strand piece to the extent that not all of the lines in the Redirection of a strand piece is affected, at the same time for conveying further Strand pieces are out of operation; rather, it should be possible even when redirecting a strand piece is introduced or terminated from one line to another, the other Keep the line still in operation.
