Macrosegregation and shrinkage porosity in large steel ingots are key factors restricting the
homogenization of large cast and forged parts. Due to the complex mechanisms of their …

Digitalisation of metallurgical manufacturing, especially technological continuous casting
using numerical models of heat and mass transfer and subsequent solidification has been …

VCoNi medium-entropy alloys (MEAs) have been reported to exhibit a high ultimate tensile
strength, a good hydrogen embrittlement resistance and an excellent abiotic corrosion …

A novel method by adding inorganic heat absorption material (IHAM) into the molten steel
was proposed to improve the quality of large steel ingots. The IHAM was found to melt and …

In the present work, the impact of hot top geometry and thermal history on the Columnar-to-
Equiaxed Transition (CET) point, of a 12 MT steel ingot was determined using finite element …

Dendritic deformation induced by convection of thermal fluid is one of the factors leading to
dendrite fragmentation and plays a crucial role in grain structure of alloy, which lacks in …

Macrosegregation, as a typical internal metallurgical defect of steel ingots, determines the
mechanical properties and service life of the finished steel. Currently, the mold design is the …

The influence of hot-top designs with different heat capacities on the distribution of positive
and negative macrosegregation was investigated on a 12 metric tonne (MT) cast ingot made …

The solidification process of castings is prone to shrinkage porosity and macroscopic
segregation defects. Utilizing a reduction technique to control the defects in the solidification …

We proposed a new technique route of directional solidification for the manufacture of super
slab. A 7-t laboratory-scale thick slab was casted and characterised for trial. To further …
