Abstract

The systematic measurements of continuous slab casting to quantify the effect of oscillation conditions and superheat on mold powder consumption rate, oscillation mark depth, and hook characteristics were described. The mold powder consumption rate per oscillation cycle depends strongly on positive strip time and also correlates with frequency and nagative strip time. The increasing superheat has a strong effect on decreasing hook size, including both hook length and depeth. The increasing oscillation frequency shortens solidification time, negative strip time, and positive strip time. Increasing the asymmetry of non-sinusoidal oscillation tends to increase mold power consumption, and increases the deflection angle of thick hooks.
