Slitting-proсess

         The technology of reinforcing steel manufacturing through the slitting process means forming an intermediate roll consisting of several round profiles connected by a thin (~0,5 mm) bulkhead while performing rolling.

         The further lengthwise slitting of a roll into separate parts is performed in the interstand space by non-drive sphenoid rollers through the wedging process. Further on, the formation of each roll into the finished cut is performed according to different calibres.

Advantages of this technology:

  • decrease of cost per unit:

- electric power per ton of rolled product;

- gas per ton of heated billet;

- rollers per ton of rolled product;

  • increase of the metal yield;
  • reduction of heat loss and other power inputs in the process of rolling, which provides obtaining of stable profile size and mechanical properties of finished rolled product.
