Finite Element Analysis of Continuous Induction Reheating of Hot Steel Long Products

Journal of Iron and Steel Research International 2012年第S2期19卷 743-748页

作者： taras petrica FIRETEANU Virgiliu EPM NM Laboratory POLITEHNICA University of Bucharest

This paper deals with the study of induction reheating of long steel products starting from an initial temperature of around 700 Celsius degrees,based on finite element *** industrial innovative technologies are considered:reheating of hot billets between the continuous casting lines and the rolling mill facilities and reheating of steel rails before quenching,if the rail upper side hardening is included in the rolling mill *** finite element analysis of coupled electromagnetic and thermal phenomena takes into account the dependences on temperature of electromagnetic and thermal properties of steel.

Journal of Iron and Steel Research International 2012年第S2期19卷 717-721页

作者： FIRETEANU Virgiliu POPA Monica PASCA Sorin taras petrica EPM_NM Laboratory POLITEHNICA University of Bucharest University of Oradea Faculty of Electrical Engineering and Information Technology

This paper deals with finite element study of the scanning induction heating of the magnetic steel sheets in transversal flux devices,taking into account the magnetic nonlinearity and the dependence on temperature of steel *** decrease of the non-uniformity of the transversal profile of sheet heating as effect of the magnetic or electromagnetic screening of the sheet lateral sides was proved.

The possibilities of entering new markets for Romanian companies from wood manufacturing industries

引用

Chinese Business Review 2010年第9期9卷 13-21页

作者： Mester Liana Eugenta Bugnar Nicoleta Georgeta Mester Dinu Grigore petrica Dana Maria University of Oradea Oradea 410605 Romania Parisot Green Sofa Oradea 410605 Romania . Mobila Alfa Oradea 410605 Romania

Romania has the potential of resources, labor and real capacity to adapt to the gait of a global economic competition. But it required a long term policy and environment which could support this potential value. If not, we will risk turning into a consumer economy, consumption will not be funded on internal production and become supplier of labor services for peripheral. In the context of economic crisis, Romanian furniture retains its significant competitive advantages, including the price in export markets. The most important markets for exporters of furniture from Romania are Ukraine and Russia, markets with great potential, but affected by problems such as devaluing local currencies, and recently, imposing new duties.
