Уточненная математическая модель электрогидравлического привода качания кристаллизатора высокоскоростной МНЛЗ

Abstract

At present time the high emphasis is placed on the problems of the quality improvement and increase of the metal cast speed at the machines of the slugs continuous casting. One of the ways of solving of this task is using of hydroelectric drive of the mechanism of the crystallizer swinging, which allows to vary frequency and amplitude of swinging and also to change the principle of crystallizer. In the work there is presented the improved mathematical model of the crystallizer swinging mechanism in the form of the automatic control system, using of which one can investigate the influence of different parameters of the system on quality and productivity of the machines of the slugs continuous casting.
