СПОСОБ И УСТРОЙСТВО ДЛЯ ОБРАБОТКИ ВИБРАЦИЕЙ НЕПРЕРЫВНО-ЛИТЫХ ЗАГОТОВОК

摘要

FIELD: metallurgy. ^ SUBSTANCE: crystalliser for continuous casting of blanks contains a case with a sleeve installed in it on spring packing components. A spherical bushing is assembled on the lower end of the sleeve; the said bushing facilitates turning of the sleeve in the fixture. When liquid melt of metal is poured into the sleeve, vibration generators arranged in upper and lower portions of the case transfer ternary transversal-longitudinal vibrations to the sleeve. Two-component vibrations are transferred to the upper portion of the sleeve; at that these vibrations are perpendicular to the longitudinal axis of the sleeve along elliptic or polypetalous trajectories. Vibrations along the longitudinal axis of the sleeve are transferred to its lower portion. ^ EFFECT: improvement of thermal mode of metal crystallisation and reduction of resistance to continuous cast blank motion through a crystalliser. ^ 7 cl, 2 dwg
