CAST STRAND'S STRUCTURE QUALITY RESEARCH IN RESPECT TO METHOD OF THE LIQUID STEEL FLOW THROUGH CC DEVICE'S TUNDISH.

CC process has great importance on achieving high quality cast strands. On this stage of production last metallurgic interventions are wage, which regards to liquid steel and also primary structure of the solidifying steel ingots forms. This article presents results of the research, that applies to influence of the liquid steel mixing method in tundish on steel ingots' primary structure. Study of the flow conducted on physical model of the triple-stranded tundish, which provided results formed as RTD curves. Generated curves were put together with primary structure's metallographic test results of the individual cast strand's cast in actual CCM. That listing allows to valuate influence of the liquid steel mixing method in tundish on steel ingots' primary structure quality. [ABSTRACT FROM AUTHOR]
