Vmesno korito (ponovca), ki je del naprave za kontinuirno litje, služi kot vmesni člen med livnim loncem in kokilo oz. kristalizatorjem. Njegova funkcijaje razdelitev taline med posamezne žile in kot zbiralec taline med menjavo livnih loncev pri sekvenčnem vlivanju. Med mestom dotoka taline v vmesno korito in posameznimi iztoki se talina intenzivno premešava. Najprimernejši način analize toka taline v vmesnem koritu je fizikalno in matematično modeliranje v modelih iz poliakrilnega stekla. V tekstu je opis in grafični prikaz tokov v vmesnem koritu. Na osnovi video posnetkov in fotografskih posnetkov smo določili tokovnice oz. smeri toka tekočine v modelu vmesnega korita in prikazali gibnje taline v vmesnih koritih.

Abstract

Tundish as a part of continous casting equipment connects casting ladle and mould. Its function is the distribution of melt to single stands, and to be melt accumulator during the ladle change in sequential casting. Between the melt inflow to tundish and single outflows, the melt is intensively mixed by turbulence. The most suitable way of analyzing melt flows in the tundish are physical scaled models made of plexiglas, and mathematical modelling. Paper describes enables to determine the flow lines and flow directions, and thus the flow of melt in the tundish can be forecast.
