Modelling of the solidification process and the chemical heterogeneity of a 26NiCrMov115 steel ingot

Abstract

Steel making at ŽĎAS, a.s. using secondary metallurgy technology makes it possible to produce liquid metal with high levels of metallurgical cleanliness. During the casting and subsequent cooling of forging ingots, the steel solidification takes place. Directional material solidification, grain size, chemical heterogeneity and discontinuities can have a negative effect on the products’ final properties. The comparison of the chemical composition based on a numerical calculation with the heterogeneity of the real ingot has proven the possibility of using MAGMA software to model the casting and solidification of ingots for open-die forgings made from 26NiCrMoV115 steel.
