Pollutant Emissions, Control and Prevention in the Secondary Copper Industry
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
This paper presents an analysis of pollutant emissions specifics to copper waste
valorization. There are made appreciations of the role and importance which have
the characteristics of mixed charge with waste having a ...
Steel and Refractory Chemical Interactions and Mechanical Behavior of Plates for Sliding Gate During Steel Continuous Casting
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The main objective to increase CC productivity as well as steel quality by using
optimized refractory from ladle-tundish-to-mold lead to techniques that allow the
prediction of steel and refractory chemical interactions ...
X-Ray Diffraction Study of the Rewverse Martensitic Transformation in Cu-Al-Ni Shape Memory Alloy
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The paper presents an X ray diffraction study for a cooper based shape memory
alloy. The behavior of CuAl13Ni4 alloy, which exhibits a peculiar property, is
evaluated by structural changes. On cooling, the martensitic ...
Half-Finished Technology of Steels and Fatigue Strength
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper presents the bending fatigue testing for four steel brands. The test
showed that the fatigue strength is decreasing with the increasing of both ingot size
and the rolled sheet thickness. The fatigue strength ...
Structural Characteristics in Cobalt Based Alloys
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
In the present paper there are presented results of investigations on samples of
partially removable denture made of cobalt base alloys (Co-Cr-Mo) regarding
specific structural analysis: determination of structural phases ...
Behaviour of Some Important Components in a cold Rolling Mill
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
For a good behaviour of mill parts and accurate functioning it is necessary to
have an integrated system for all mill tandem. It is important to know the speed
controls and strip tension in correlation with torque, ...
Modelling by Finite Element Analysis Method of Stress State Establishing for an Alloy Steel
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper presents some results about the tension state in samples subject to
pure bending fatigue process. Numerical simulation based on finite element method
was used. The tension field induced by a vertical deformation ...
Contribution in the Domain of the Contact Stresses Between Cylinders of Cold Rolling
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
Elasto-plastic contact stresses between working cylinder and support cylinder of
cold rolling using FEM are presented in this paper. Pressure and tractions resulted
from the rolling process were obtained by using a ...
On the Constitutive Equation of a Low Carbon Steel
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The paper shows the results of the researches concerning the equation of
deformation behavior of low carbon steel. The behavior law is established starting
from the experimental torsion moment. The composed constitutive ...
An Analytical Procedure for the Prediction of the Stress-Strain State in Notches Under Multiaxial Fatigue
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
This work presents an analytical procedure for estimating elastic-plastic
stresses and strains in notched shafts subjected to synchronous non-proportional
torsional and tensile cyclic loading. The specification of the ...
