Teodor Vasiu:Statisticalanalysis ofelectrodeconsumption ofelectricarcfurnaces

Metalurgia (55) 2003, nr.5, p.5

The paper introduces the statistic processing of a set of experimental data, referring to the electrode consumption in the electric ovens. The conclusions resulting from the interpretation of the calculation values allow further considerations on the elaboration technological process.

Gheorghe Chitu:Investigationsregarding theimproving ofsteelproduction in Romania andworldwide

Metalurgia (55) 2003, nr.5, p.9

In order to increase of efficiency of the Iron and Steel Industry, The Metallurgical Research Institute (ICEM) initiated an analysis regarding this industrial branch both in Romania and world wide.

The results indicated that increasing of finished products value could be reached by improving of production structure. Increasing values of 70 ¸ 160 USD/ton could be expected, contributing to the revamping of Romanian Iron and Steel Industry.

Petrica Alexandru:Numericalmodelling ofcylindricalsteelpartscooling

Metalurgia (55) 2003, nr.5, p.20

A mathematical  model,  based  on  the

 „before finite-difference” technique, has been developed. The model has been applied to the water spray quenching of steel bar, the grade OLC 35, with 75 mm diameter and 180 mm height.

Lilica Ivanescu:Mathematicalmodelling oftemperaturefield in therotorhousing of aninductionelectromagneticcoupling,made oftechnicallypureiron

Metalurgia (55) 2003, nr.5, p.25

Applications of the technical pure iron used to manufacture some component parts of the induction electromagnetic couplings, such as rotor jacket coils housing, polar piece blades.

It has been established the thermal calculation relation for the technical pure iron from which the rotor jacket of the induction electromagnetic coupling was made according to the following parameters: specific power loss, thermal conductivity coefficient, convection and radiation heat exchange coefficient, ambient temperature.

Tiberiu Manescu, Zeno -Iosif Praisach, Camelia Pinca Bretotean : Considerationsregarding thematerialused inmanufacturing ofvalveobturators inhydropowerplants

Metalurgia (55) 2003, nr.5, p.29

The paper presents some aspects regarding the material used in manufacturing of the valve’s obturator which are used in the hydroenergetic power plant. In the issue are illustrated some results regarding the strength calculation, applying FEM, for the specific material of the valve’s obturator.
