Desigh of the hydraulic pressure servo actuation type casts the semifinished product crystallizer shake-out equipment

Abstract

The crystallizer shake-out equipment is in the continuous casting key equipment, its vibration form, the control mode as well as the online monitor and the adjustment, have the material effect to the continuous casting quality. Therefore, the research continuous casting crystallizer shake-out equipment and the control technology have the vital practical significance. This article through the elaboration which evolves to the continue caster crystallizer technological development and the crystallizer vibration way, proposed the battery solution servo actuates, and has carried on the substantive analysis to its vibration form and the principle of work. Then has drawn up the organization diagram, and has carried on the analysis computation to its parameter of movement and the technological parameter! Finally through the examination, the organization simulation analysis has completed this design!
