WebThis development allowed successful implementation of the technology on a conventional billet caster where surface roughness was improved and the oscillation mark depth greatly reduced, allowing elimination of billet surface conditioning. Subsequently, the pulsative technology was trialed on a slab caster with similar positive results. WebMay 8, 2024 · Such ripples, which are usually less than 10 cm in height, commonly display rounded symmetrical troughs and rounded, or sometimes sharp, symmetrical peaks, although many wave-generated ripples are not symmetrical owing to an inequality in forward and backward motion associated with the wave action.
