A two-dimensional heat conduction problem in which a liquid becomes solidified by heat transfer to a sinusoidal mold of finite thickness is solved by using a linear perturbation method. The liquid perfectly wets the sinusoidal mold surface prior to the beginning of solidification. This leads to a corresponding undulation of the solidified shell thickness. Both surfaces of the mold follow a sinu...

High turbulence at the liquid steel−mold flux interface results in mold entrapments, which can generate nonmetallic inclusions during ingot‐casting process. Those are detrimental to final steel quality. The teeming process ingot casting is typically conducted using uphill method. authors propose a novel alternative method side process, decreases free surface. To define optimum operational condi...

A new, computationally efficient algorithm has been implemented to solve for thermal stresses, strains, and displacements in realistic solidification processes which involve highly nonlinear constitutive relations. A general form of the transient heat equation including latent-heat from phase transformations such as solidification and other temperature-dependent properties is solved numerically...

aluminum anodes have been widely used in the cathodic protection of marine structures. however there are conditions in which these anodes become passivated or face some localized or unwanted corrosion, which influences their efficiency. addition of alloying elements such as zn and in not only have improved the efficiency of the anodes but also the effect of casting parameters such as ultra melt...

During continuous casting, electromagnetic braking (EMBr) is a widely used technology to improve the quality of steel product. The EMBr takes benefit generation Lorentz forces that are induced by interactions melt flow with externally applied magnetic fields. In present paper we propose and investigate new type EMBr, named vertical-combined (VC-EMBr) in application Compact Strip Production (CSP...

For die-casting, various approaches to finding the optimal control settings and optimal mold by using a computational fluid dynamics (CFD) simulator have recently been studied and applied. However, the optimal value obtained by using a conventional CFD simulator does not consistently agree with experiment, owing to computational error. Accordingly, we analyze the problem of optimization with a ...
