Change of pattern of solidiication in bottom poured ingots,represented by a mathematical models and its effect on the appearance of defects in seamless pipes of C.V.G sidor

摘要

This papoer shows a mathematical model based on finite elements,applied to bottom poured shell ingots of C.V.G.Sidor Plant.The model was used as a strategy to determine the thermal effects that are produced when solidification ocnditions are mdoified without intefering with the production process.The modification consisted fo placing a thermal insulator on top of mould.
