Physical Modelling of Flow Pattern in 5-strand Asymmetrical Tundish with Baffles.

Popis výsledku v původním jazyce

Nature of steel flow in the five-strand asymmetrical tundish situated at CCM No. 1 located in Trinecke Zelezarny. The plexiglass model in a 1:4 geometric scale to the real plant tundish and is located at the Department of Metallurgy, FMME, VSB-TechnicalUniversity of Ostrava. Evaluation of molten steel behaviour under the conditions of two baffle-type perforated walls inserted into the tundish impact area. The baffles were placed symmetrically between the impact area and the nearest casting strands No.3 and 4. Five variants of tundish refilling regimes were studied. Permanent concentration change (Heaviside unit step) was used. KCl was used as a marker. The visualization was the impulse injection (Dirac pulse) of KMnO4 aqueous solution. The minimum residence times and moments of 0.5 dimensionless concentration achievement were acquired from the obtained F-curves. The results gained from experiments were discussed by mathematical and statistical methods - the coefficient of variation w
