Simulation of Convection and Macrosegregation in a Large Steel Ingot
segregates. Although good agreement with experiments was MACROSEGREGATION in large steel ingots is one achieved, the model relied on many approximations (such of the most well-known and now classical problems in the as estimating the flow velocities). It should also be menfield of solidification and casting.[1] It arises from the relative tioned that many models have appeared in the literature ...
متن کاملEffect of Current on Structure and Macrosegregation in Dual Alloy Ingot Processed by Electroslag Remelting
Macrosegregation is a very common problem for the quality control of all cast ingots. The effect of current on the structure and macrosegregation in dual alloy ingot processed by electroslag remelting (ESR) was investigated experimentally with various analytical methods. In this study, the electrode consisted of NiCrMoV alloy bar (upper part) and CrMoV alloy (lower part) with a diameter of 55 m...
متن کاملUsing a Three-phase Mixed Columnar-equiaxed Solidification Model to Study Macrosegregation in Ingot Castings: Perspectives and Limitations
A three-phase model for mixed columnar-equiaxed solidification was recently developed. The most critical features, necessary for modelling the macrosegregation, were considered: the progressive growth of the columnar dendrite trunks from the ingot surface, the nucleation and growth of the equiaxed crystals including the motion of the equiaxed crystals, the thermal and solutal buoyancy flow and ...
