Simulation of the Hydrodynamics of the Bath in the Tundish of the CCM during the Process of Purging Steel with Argon when Using Flow Modifiers

Abstract

The results of computational experiments on studying parameters of the hydrodynamics of the bath with liquid steel in a 50-ton tundish of a slab CCM when using flow modifiers and introduction of argon through purge beams in pouring chambers are presented. Rational arrangement of partitions, configuration of metal receiver and purge beams for redirecting flows in pouring chambers into the subslag zone for increasing the efficiency of metal purification were determined.
