Abstract
A straightener for a multistrand continuous-casting machine. The straightener includes fulcrum rolls and reaction rolls which precede and follow the fulcrum rolls. The fulcrum rolls for all the strands are idlers and are coaxial, but the reaction rolls which follow the fulcrum rolls and engage intermediate strands are offset in a direction parallel to the length of the strands from the reaction rolls which engage the outer strands. The offset enable the drives for the bottom rolls opposite the intermediate reaction rolls to be connected directly to the bottom rolls.
Claims8
In a multistrand continuous-casting machine in which two outer strands and at least one intermediate strand travel in parallel paths located close to one another, an improved straightener comprising:
- coaxial fulcrum rolls for engaging the bottom faces of the respective strands and defining a common lower tangent line for the strands;
- outer and intermediate reaction rolls for engaging the upper faces of the respective strands both preceding and following the fulcrum rolls;
- the intermediate and outer reaction rolls which follow the fulcrum rolls being spaced at different distances from the axis of the fulcrum rolls;
- respective bottom rolls opposite said reaction rolls;
- and
- drive means operatively connected with the bottom rolls opposite the outer and intermediate reaction rolls which follow the fulcrum roll and being located outside the paths of the outer strands;
- said drive means being aligned with the respective rolls which they drive.
