Numerical modelling of macrosegregation in three-dimensional continuous casting of steel billets

Numerical modeling of porosity and macrosegregation in continuous casting of steel

1 ABSTRACT The continuous casting process is a widely used technique in modern steel plants. However, it is a complicated process that is not well understood. The objective of this research is to model the porosity and macrosegregation due to shrinkage related effects and solid deformation in the continuous casting of steel. Solid phase movements due to bulging and variable roll gap are modeled...

Numerical Simulation of Slab Broadening in Continuous Casting of Steel

Continuous Casting of Steel

Continuous casting is used to solidify most of the 750 million tons of steel produced in the world every year. Like most commercial processes, continuous casting involves many complex interacting phenomena. Most previous advances have been based on empirical knowledge gained from experimentation with the process. To further optimize the design and improve the continuous casting process, mathema...

Prediction of optimal operating parameters for continuous casting of billets

Process optimization determines process parameters that maximize or minimize (optimize) so aspect of a process (the obieciive function), while ensuring that the process operates wr established limits. In this work a mathematical model that simulates heat flow and solidification continuously cast steel strand is coupled with mathematical optimization techniques to predict opt process parameters ...

Numerical and Physical Modelling of Steel Flow in a One-strand Continuous Casting Tundish

Constantly increasing customers demands for the production of high and very high-quality steels, promote the intensive technological development of their production. Since the dominating method of global steel production is continuous casting, the tundish has become very important metallurgical unit. Nowadays, tundish is not only a storage vessel which guaranty the continuous casting of steel, ...
