CURVILINEAR PLANT FOR CONTINUOUS CASTING OF SORTED BILLETS Russian patent published in 2019 - IPC B22D11/00 

FIELD: technological processes.

SUBSTANCE: invention relates to continuous casting of profiled workpiece. Vertical crystallizer (1) with sleeve (14) with heat-removing working surfaces (34) arranged in fixed housing comprises head and tail parts with cooling circuits. High-frequency hydraulic swinging mechanism of the crystallizer, which provides rocking frequency n = 14–45 Hz, is built into the head of the crystallizer and is configured to change the oscillation amplitude in the range of a = 3–12 mm. Tail part of crystallizer is made in the form of longitudinal sections, each of which is made with possibility of changing taper of heat-removing working surface of internal cavity of crystallizer. On the crystallizer outlet there installed are deforming rolls (8) providing simultaneous side reduction and bending of the continuously cast billet to process radius Rt. Metal level sensors in the sleeve, which are made in the form of thermal sensors (41), and sensors (42) of mutual movement of planes of sections of the tail part of the crystallizer are connected to the electronic control unit (21).

EFFECT: higher rate of continuous casting, quality of continuously cast billet.
