Raziskava toka jeklene taline v vmesni ponovci

Kovač, Sandro (author), Knap, Matjaž (mentor)

V okviru diplomskega dela smo s pomočjo računalniškega programa simulirali tok jeklene taline v petih različnih vmesnih ponovcah. V zadnjih letih se vse več posvečamo tehnologiji izdelave jekla v vmesni ponovci, ker je ena od pomembnejših metalurških agregatov. Z njeno pravilno zasnovo veliko prispevamo k višji čistoči jeklene taline in s tem boljši kvaliteti izdelanega jeklenega polizdelka. Teoretični del zajema pregled razvoja tehnologije, opis, proces in prednosti kontinuirnega vlivanja jekla, temu sledi podroben opis vmesne ponovce. V eksperimentalnem delu smo numerično modelirali tok jeklene taline v različnih vmesnih ponovcah. Prve tri vmesne ponovce so bile brez pregrade in so se med seboj razlikovale v geometriji, zadnji dve pa sta imeli pregrado na različnih oddaljenostih. Rezultate numeričnega modeliranja smo predstavili s slikami, ki prikazujejo hitrostna območja in s tokovnicami. Za še bolj podroben vpogled v dogajanje smo ponovco vzdolžno in prečno prerezali ter izrisali grafe hitrosti po dolžini in višini ponovce.

• Title: Research of steel melt flow in tundish

Abstract

In this diploma thesis we have simulated the flow of steel melt in five different tundishes. In last years we are increasingly devoting ourselves on tundish technology and its effect on steel making, as it its one of the most important metallurgical aggregate. With its proper design we greatly contribute to the higher purity of steel melt and thus better quality of the manufactured steel product. Theoretical part includes review of the development of continuous casting, process flow, advantages, followed by detailed description of tundish. In pratical part we numerically simulated flow of steel melt in various tundishes. The first three were barrier-free and differed in geometry, while the last two had a barrier at different distances. Results were presented with images showing velocity zones and streams. For even more detailed insight, we have cut tundish longitudinally and transversely in order to make various velocity vs tundish height, length diagrams.
