Abstract
A rolling monoblock comprises: a first block (B1) of rolling stands (G1-Gm) and a second block (B2) of rolling stands (Gm+1-Gn). According to the invention, an annular path (A) of cooling of the rolled section (11) is foreseen between the two blocks (B1, B2).
Claims6
Rolling monoblock comprising:
- a first block of rolling stands and a second block of rolling stands;
- an annular path being provided between said rolling stands for cooling of a rolled section, said annular path sequentially including the following devices in a rolling direction:
- a first drawing mechanism for keeping the rolled section under tension at an exit of said first block;
- a cooler configured for cooling an entirety of the rolled section provided from said first drawing mechanism;
- shears for cutting a head of the rolled section;
- a second drawing mechanism configured for tensioning the rolled section at an exit of said cooler;
- a circular loop for avoiding tensions on the rolled section during passage between said blocks;
- and
- a third drawing mechanism upstream of said second block in the rolling direction, said third drawing mechanism configured for ensuring entrance of the rolled section into said second block.
