TLDR
In this paper, both the velocity of the molten metal, surface heat extraction rate and also the mold shapes are taken into account in the numerical analysis of the continuous casting process of continuous casting.Abstract:
Thermal physics of continuous casting is strongly dependent on the velocity of the molten metal, surface heat extraction rate and also on the mold shapes. In the present numerical study, both the m...read more

Numerical and experimental study of the heat transfer process in friction stir welding
M Song,Radovan Kovacevic +1 more
TL;DR: In this paper, a mathematical model to describe the detailed three-dimensional transient heat transfer process in friction stir welding (FSW) is presented, where the heat input from the tool shoulder is modelled as a frictional heat and the heat from a tool pin is modeled as a uniform volumetric heat generated by the plastic deformation near the pin.

Modelling of three-dimensional temperature field inside the mould during continuous casting of steel
TL;DR: In this paper, the temperature field inside the mold in the billet during the continuous casting of low carbon steel is analyzed using the finite element method (FEM) and ANSYS.

Factors Affecting the Formation of Shell and Longitudinal Cracks in Mold during High Speed Continuous Casting of Slabs
TL;DR: In this article, the authors investigated factors affecting the formation of shell and longitudinal cracks on the shell for high speed continuous casting of slabs and found that withdrawal speed of slab, stream velocity from submerged nozzle, mold taper, and mold oscillation have shown respective influence on the formation.

Growth of Solidified Shell Just below the Meniscus in Continuous Casting Mold
TL;DR: In this paper, the authors investigated the cooling and solidification rate of hypo-peritectic steel slabs cast at 3-5 m/min and found that there is a delaying period of solidification growth at the beginning, till the shell grows up to about 1 mm thick.
