Transport and Entrapment of Particles in Continuous Casting of Steel
The entrapment of inclusions, bubbles, slag, and other particles into solidified steel products is a critically-important quality concern. During continuous casting, particles may enter the mold with the steel flowing through the submerged nozzle. In addition, mold slag may be entrained from the top surface. A computational model has been developed to simulate the transport and entrapment of pa...
متن کاملTransport and Entrapment of Particles in Steel Continuous Casting
A particle-capture model based on local force balances has been developed, implemented into computational models of turbulent fluid flow and particle transport, and applied to simulate the entrapment of slag inclusions and bubbles during the continuous casting of steel slabs. Turbulent flow of molten steel is computed in the nozzle and mold using transient computational fluid flow models, both ...
متن کاملSolidification and Particle Entrapment during Continuous Casting of Steel
Avoiding particle entrapment into the solidifying shell of a steel continuous caster is important to improve the quality of the continuous cast product. Therefore, the fluid flow dynamics in the steel melt and mushy zone, heat transfer and solidification of the steel shell, as well as the motion and entrapment of inclusion particles during the casting process were investigated using computation...
متن کاملFlow Dynamics and Inclusion Transport in Continuous Casting of Steel
The quality of continuous cast steel is greatly affected by fluid flow in the mold region, especially involving transient phenomena and the transport of inclusion particles. As part of a long-term effort to develop and apply comprehensive models of these and other phenomena, this paper reports on studies to evaluate the relative accuracy of models of three different fluid flow phenomena in cont...
متن کاملContinuous 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...
