Abstract:

The present paper evaluates the effect of the nozzle characteristics on the heat transfer and phase change of the low carbon steel during the continuous casting process. A three-dimensional energy equation and a solidification model are used to drive the governing equation of the phase change and temperature distribution. A linear relation is obtained to predict the temperature-dependent of the solid volume fraction in the mentioned steel. An effective thermal conductivity is used to simulate the advection effects of the liquid steel. The effective heat capacity is assumed to model the phase change in the mushy zone. The predicted values of the model are compared with the experimental ones. The regression values confirm a good agreement between the modeled and experimental values. The effects of geometry of the slab and the secondary cooling characteristics are examined on the heat transfer and solidification of the steel slab. The slab thickness has a significant on the solidification and by increasing this parameter, the metallurgical length will increase.

Thermal Simulation of Solidification Process in Continuous Casting

In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...

Solidification 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...

Thermal-mechanical behaviour during initial solidification in continuous casting: steel grade effects

A transient finite-element model (CON2D) is applied to compute temperature, stress, and distortion of the steel shell during initial solidification. The model incorporates temperaturedependent properties, thermal shrinkage, phase transformations, and different elastic-viscoplastic constitutive equations for each phase (liquid, d, and c). The effects of sudden metal level fluctuations are simula...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
