Influence of Submerged Entry Nozzle on Intermixed Zone in Round Blooms with a Diameter of 525 mm / Wp?yw Wylewu Zanurzeniowego Na Strefe Przejsciowa W Okrag?ych Wlewkach Ciag?ych O Srednicy 525 mm
This work compares the experimental results of nickel concentration measurements in the intermixed zone of the continuously cast round blooms with a diameter of 525 mm using two types of submerged entry nozzles (SEN) - a straight-through nozzle and one with 5-ports. Based on determination of the system and optical interface in the blooms a detailed study of concentration profiles on the bloom surface in a small radius area, on the right side and then also on a cross-section of the blooms, was carried out. The results were further analysed using approximation models, and were to be used to verify the proposed model for predicting intermixed zones for a continuous casting machine, developed based on the results of physical and numerical modelling.
