METHOD FOR SEMI-ENDLESS OR ENDLESS ROLLING OF CAST METAL SUCH AS CONTINUOUSLY CAST STEEL BILLET OPTIONALLY SUBJECTED TO CROSS CUTTING AFTER CRYSTALLIZATION AND CASTING-ROLLING AGGREGATE FOR PERFORMING THE SAME Russian patent published in 2008 - IPC B21B1/46 

FIELD: processes and equipment for rolling continuously cast billets.

SUBSTANCE: after crystallization billet is cross cut; its measured length pieces are fed to furnace with roller hearth for uniform heating and for matching with rolling temperature. Measured length pieces of billet are introduced to line of rolling stand while process of casting billet is going on during rolling process without interruptions. Processes of casting and rolling are matched in such a way that to remain buffer time interval between termination of rolling previous measured length piece and introducing new measured length piece of billet to rolling mill due to lowering casting speed in order to change rolls. During casting process after cross cutting of billet, final thickness of rolled piece and(or) speed of introducing billet to line of rolling mill are increased. Casting -rolling aggregate includes furnace with roller hearth, apparatus for cross cutting of billet and apparatus for removing scale mounted just after cross cutting apparatus and dividing apparatus behind line of rolling mill, cooling and coiling zones. At inlet and at outlet of furnace there are roller type guiding sections with bending and (or) straightening units.

EFFECT: enhanced efficiency of rolling continuously cast billets.
