| 1 | Fluid Flow and Heat Transfer Modeling of AC Arc in Ferrosilicon Submerged Arc Furnace显示文摘A two-dimensional mathematical model was developed to describe the heat transfer and fluid flow in an AC arc zone of a ferrosilicon submerged arc furnace.In this model,the time-dependent conservation equations of mass,momentum,and energy in the specified domain of plasma zone were numerically solved by coupling with the Maxwell and Laplace equations for magnetic filed and electric potential,respectively.A control volume-based finite difference method was used to solve the governing equations in cylindrical coordinates.The reliability of the developed model was checked by experimental data from the previous available literature.The results of present model were in good agreement with the given data comparing with other models,because of solving the Maxwell and Laplace equations simultaneously in order to calculate current density.In addition,parametric studies were carried out to evaluate the effects of electrical current and arc length on flow field and temperature distribution within the arc.According to the computed results,a lower power input led to a higher arc efficiency. | M Mohebi Moghadam S H Seyedein M Reza Aboutalebi | 2010 | Journal of Iron and Steel Research(International)2010，17，9： | 5 |
| 2 | Physical Simulation of Hot Deformation and Microstructural Evolution for 42CrMo4 Steel Prior to Direct Quenching显示文摘Direct quenching and tempering(DQ-T) of hot rolled steel section has been widely used in steel mill for the sake of improvement of mechanical properties and energy saving.Temperature history and microstructural evolution during hot rolling plays a major role in the properties of direct quenched and tempered products.The mathematical and physical modeling of hot forming processes is becoming a very important tool for design and development of required products as well as predicting the microstructure and the properties of the components.These models were mostly used to predict austenite grain size(AGS),dynamic,meta-dynamic and static recrystallization in the rods immediately after hot rolling and prior to DQ process.The hot compression tests were carried out on 42CrMo4 steel in the temperature range of 900-1 100 ℃ and the strain rate range of 0.05-1 s-1 in order to study the high temperature softening behavior of the steel.For the exact prediction of flow stress,the effective stress-effective strain curves were obtained from experiments under various conditions.On the basis of experimental results,the dynamic recrystallization fraction(DRX),AGS,hot deformation and activation energy behavior were investigated.It was found that the calculated results were in good agreement with the experimental flow stress and microstructure of the steel for different conditions of hot deformation. | A H Meysami R Ghasemzadeh S H Seyedein M R Aboutalebi R Ebrahimi M Javidani | 2009 | Journal of Iron and Steel Research(International)2009，16，6： | 4 |
| 3 | NUMERICAL PREDICTIONS AND EXPERIMENTAL VALIDATIONS OF DUCTILE DAMAGE EVOLUTION IN SHEET METAL FORMING PROCESSES显示文摘Prediction of forming limit in sheet metal forming is among the most important challenges confronting researchers. In this paper, a fully coupled elastic-plastic-damage model has been developed and implemented into an explicit code. Due to the adoption of the plane stress and finite strain theories, model can predict deformation and damage of parts quickly and accurately. Also, damage initiation, propagation, and fracture in some operations are predicted and validated with experiments. It is concluded that finite strain combined with continuum damage mechanics can be used as a quick tool to predict ductile damage, fracture, and forming limits in sheet metal forming processes. | Farhad Haji Aboutalebi Mahmoud Farzin Mohammad Mashayekhi | 2012 | Acta Mechanica Solida Sinica2012，25，6： | 3 |
