In this research experiment computational fluid dynamic (CFD) models were constructed, within Ansys Fluent TM v.R1, to investigate phenomena occurring during the Vertically Upwards Continuous Casting (VUCC) of 8 mm diameter, oxygen free copper (OFCu) for alterations casting speed. The simulated influence heat transported over a 0.1 air gap formed die was investigated and value wall transfer coe...

Protective slag is coated on the surface of molten steel during continuous casting, flow and heat transfer state protective a decisive factor affecting inflow consumption liquid also an important prerequisite for stabilizing improving quality casting billets. Based Navier Stokes fluid momentum conservation equation energy equation, two-dimensional longitudinal numerical model describing flow/he...

The solidification of metals continues to be a phenomenon of great interest to physicists, metallurgists, casting engineers and software developers. It is a non-linear transient phenomenon, posing a challenge in terms of modelling and analysis. During the solidification of a casting in a mould, the heat-transfer between the casting and the mould plays a vital role. This paper attempts to study ...

In continuous casting of steel, the interfacial gap between the mold and the solidifying shell controls heat transfer in the process and is responsible for lubrication and the prevention of cracks and other defects. Mold slag forms when mold powder added to the top surface of the steel melts, and is the best current practice to perform these important functions. The properties and behavior of t...

Two differently-produced open-cell aluminum foams were compared to a commercially available finned heat sink. Further, an aluminum plate and block were tested as a reference. All heat sinks have the same base plate dimensions of four by six inches. The first foam was made by investment casting of a polyurethane preform and has a porosity of 0.946 and a pore density of 10 pores per linear inch. ...

Abstract: In this paper, a new solution of solidification problems in continuous casting based on meshless method is presented with multiple strategies to solve the practical problems. An additional term is added to stabilise the computation with Neumann boundary. The enthalpy method is used to calculate the latent heat and the corresponding iterative solution is given. An iteration scheme for ...

A concept for the casting of metallic fuels pins containing low vapor pressure materials is presented and discussed. The important physics of this concept include the mass transport of americium from the melt, the induction heating and stirring of the melt, plus the casting of long slender fuel rods. This paper discusses and presents preliminary modeling results for the casting of long, slender...

This paper presents a new system to control secondary cooling water sprays in continuous casting of thin steel slabs, CONONLINE. It uses real-time numerical simulation of heat transfer and solidification within the strand as a software sensor, in place of unreliable temperature measurements. The one-dimensional finite-difference model, CON1D is adapted to create the real-time predictor of the s...

Multi-faceted experiments were conducted to measure the properties of several mold slags, needed for fundamental characterization of heat transfer and friction in the interfacial gap between the shell and mold during the continuous casting of steel. A novel apparatus was used to measure the friction coefficient between solidified mold flux and copper at elevated temperatures. The measured softe...
