Thermo-mechanical Finite Element Model of Shell Behavior in Continuous Casting of Steel
A finite-element model, CON2D, has been developed to simulate temperature, shape, stress, and hot-tear crack development during the continuous casting of steel, both in and below the mold. The stress model features an elastic-viscoplastic creep constitutive equation that accounts for the different responses of the liquid, semi-solid, delta-ferrite, and austenite phases. Temperature and composit...

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...
متن کاملThermal-mechanical Model Calibration with Breakout Shell Measurements in Continuous Steel Slab Casting
Heat-flow and thermal-stress models of continuous steel slab casting are calibrated with detailed measurements of a breakout and applied to predict longitudinal off-corner crack formation. First, a fluid mass balance is applied together with the measured slide-gate position, mold level, casting speed histories to reconstruct the transient events that occurred during the breakout, including the ...
متن کاملFinite Element Instability Analysis of the Steel Joist of Continuous Composite Beams with Flexible Shear Connectors
Composite steel/concrete beams may buckle in hogging bending regions. As the top flange of I-beam in that arrangement is restricted from any translational deformation and twist, the web will distort during buckling presenting a phenomenon often described as restricted distortional buckling. There are limited studies available in the literature of restricted distortional buckling of composite st...
