The liquid steel flow pattern inside the slab caster mould plays a vital role in governing both the quality and productivity of the caster. The steel flow in the upper re-circulating domain in the mould reaches the meniscus where it is in direct contact with molten flux layer. However at higher casting speed the flux layer itself may get entrained into the liquid steel. Control of meniscus turbulence plays an important role in attaining a better quality of product. The meniscus turbulence in the mould is highly influenced by different operating parameters viz. section size of the mould,...
