Design and plant experience using an advanced pouring box to receive and distribute the steel in a six strand tundish

Based on water and math modeling work, a refractory device was designed aim ing to improve the liquid steel flow in the tundish of the ACINDAR #2 bille t, bloom and minislab easter. The simulation work took into account sequenc e start, ladle change and steady state. The device improved flow behavior for the inner strands and helped minimizi ng slag emulsification and the contact of the steel with the air, especiall y at ladle change. Better inclusion counts and temperature homogeneity throughout the sequence were obtained when using APE in the tundish.
