METHOD FOR TWO-FLOW PRODUCTION OF ROOM AND BARRELS FROM ALLOY STEEL GRADES AND CASTING AND ROLLING UNIT FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC B21B1/46 B21D11/12 B21B13/22 

FIELD: metallurgy.

SUBSTANCE: invention relates to the double-flow production of wire rod and billet. Continuous casting of billet is carried out on a continuous billet casting machine with a two-stand straightening-pulling unit, consisting of successively installed first vertical and second horizontal rolling stands. The cast billet in a two-phase state is subjected to successively soft horizontal and vertical compression in a two-stand correct-pulling block, at the exit from which the formed billet of square section during its in-line production is sent to a discharge roller table with cut-to-size shears and a refrigerator, and when in-line production of wire rod is formed damping arc of the workpiece. After rolling, the finished wire rod is subjected to sorbitization by accelerated cooling before being coiled into a coil.

EFFECT: technological capabilities are expanding.
