Abstract

The effect of mold oscialltion conditions on slab surface quality and the effect of casting conditions on hook formation in ultralow-carbon steel were analyzed. It was found that mold power consumption rate per oscillation cycle depends strongly on positive strip time and also correlates with frequency and negative strip time. The increase in superheat was found to have a strong effect on decreasing hook size, including both hook length and depth. It was observed that increasing the asymmetry of nonsinusoidal oscillation tends to increase mold power consumption and increases the deflection angle of thick hooks.
