Abstract
This paper introduces the inverse control model of the mold hydraulic oscillation system Dynaflex of VAI at a certain steel factory,and compares the characteristics of the normal control model and inverse control model.Fourteen oscillation parameters of VAI are classified.Combined with the technology of the mold oscillation,the confirming processes of the oscillation parameters are analyzed with graphical method successfully,which provides a theoretical basis for the process design of CC mold oscillation.In the range of 0.6 ～ 1.8m/min,the positive strip time,the negative strip time and other parameters are calculated when the casting speed changes.The calculation result shows that the negative strip time is nearly constant,and the positive strip time increases with the increase of casting speed,which not only makes the oscillation marks of slab uniform,but also meets the requirement of the consumption of the mold powder.关键词
