چکیده
Abstract A model is presented that predicts the amount and location of oxide inclusions in steel castings. number size distribution inclusions, defined about a mean diameter, enters casting system at its inlet during filling process are transported to their final locations casting. Model parameters for inclusion density, drag wall friction used calculate motion particles. results study effects shape surface orientation on distributions within These compared with tracking experiments where geometry gating cope surfaces affect Measured simulated area percent coverage, count diameter range modelling distributions. The inlet, other parameters, determined which provide best agreement between measured area, count, size.

Modeling and Removal of Inclusions in Continuous Casting
Continuous casting is the central process phase with strong influence on the final quality of the steel products. Several different models for continuous casting have been developed at the Laboratory of Metallurgy at Helsinki University of Technology (TKK) concerning e.g. fluid flow, heat transfer, thermodynamic equilibria and statistical approaches. In this paper the inhouse solidification mod...
متن کاملRecent Advances in Computational Modeling of Continuous Casting of Steel
As computer power increases, computational models are able to contribute more to the understanding and design of complex processes such as the continuous casting of steel. Fluid flow models can now include phenomena such as transient behavior during steady casting, including particle transport, capture and removal. Heat flow models can include interfacial slag layer heat, mass and momentum bala...
متن کاملPhysical Modeling of Steel Delivery during Thin Slab Continuous Casting
A full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (SEN) was constructed. On the basis of the dimensionless Reynolds and Froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. In order to determine the optimum ope...
متن کاملMathematical Modeling of Heat Transfer for Steel Continuous Casting Process
Heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. A heat transfer and solidification model is described for the continuous casting of steel slabs. The model has been established on the basis of the technical conditions of the slab caster in the con...
متن کاملModeling of Reoxidation Inclusion Formation in Steel Sand Casting
A model is developed that predicts the motion and growth of oxide inclusions during pouring, as well as their final locations on the surface of steel sand castings. Inclusions originate on the melt free surface, and their subsequent growth is controlled by oxygen transfer from the atmosphere. Inclusion motion is modeled in a Lagrangian sense, taking into account drag and buoyancy forces. The in...
