CRYSTALLIZER FOR CONTINUOUS CASTING OF WORKPIECE Russian patent published in 2020 - IPC B22D11/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to continuous casting of metal. Proposed crystallizer comprises casting wheel (6) with open channel on outer surface, continuous tape (4) adjoining it to close open channel and cooling system. Cross section of the open channel is isosceles trapezoid with ratio of length of larger base (19) to length of smaller base (20) of 1.3–1.6. Cooling system includes at least four arc tubular sprinklers: external (11) located on the side of external surface (15) and continuous tape (4), internal (12) located on the side of inner surface (17), right (10) and left (13) side sprinklers located on the side of the right and left side surfaces (16) of the casting wheel. Ratio of coolant flow rate from inner surface (17) to coolant flow rate from outer surface (15) of wheel (6) is 1.9–3.0. Ratio of total flow rate of cooling liquid of side surfaces (16) to flow rate of cooling liquid of inner surface (17) makes 1.3–1.7.

EFFECT: higher technological effectiveness of continuously cast billet, increased speed of its production and improved quality of its due to elimination of formation of defects of crystallization origin.
