Simulation of Crack Formation on Solidifying Steel Shell in Continuous Casting Mold.

Thermal Distortion of Solidifying Shell near Meniscus in Continuous Casting of Steel

A two-dimensional, transient, finite-element model has been developed to simulate temperature, shape, and stress development in the steel shell, during the initial stages of solidification in the mold. The model is applied to predict the distorted shape of a vertical section through the shell, during a sudden fluctuation in liquid level at the meniscus. The calculation includes the effects of t...

Simulation of transient fluid flow in mold region during steel continuous casting

A system of models has been developed to study transient flow during continuous casting and applied to simulate an event of multiple stopper-rod movements. It includes four sub-models to incorporate different aspects in this transient event. A three-dimensional (3-D) porous-flow model of the nozzle wall calculates the rate argon gas flow into the liquid steel, and the initial mean bubble size i...

Transient Fluid-Flow Phenomena in the Continuous Steel-Slab Casting Mold and Defect Formation

Phenomena associated with the turbulent flow of molten steel in a continuous casting mold are responsible for many defects in the final product, including surface slivers, frozen meniscus hooks, captured inclusions that enter the mold from upstream, and mold slag entrapment. Animations of some of these transient flow phenomena are presented from Large-Eddy Simulations of a typical slab caster w...

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...
