Avram: Notations concerning some provisions of the
environmental law (EL). The invalidity of the principle of pollution
prohibition. The importance of pollution prevention and reduction Metalurgia (57) 2005, nr. 7, p. 5 The technical-scientific arguments by help of which it is proved that
the principle of pollution prohibition has not an engineering basis are
presented. This statement can be realised by pollution prevention and
control. There are detailed the aspects that
justify the necessity of pollution prevention, which are emphasised by the
environmental law and the engineering too. One insists on those possibilities
of the juridical norms and technologies which determine finally the pollution
diminishing. D.C.: 574 Mihaela
BĂLĂNESCU, NICOLAE Avram: Preliminary methods to assess and to prioritize the
environmental risk sources, from iron & steel industry Metalurgia (57) 2005, nr. 7, p. 13 The paper presents new preliminary
methods, used to assess and to prioritize the environmental risk
sources, from iron & steel industry. The results of the use of these own
methods within SC SIDEX SA Galati application are described as well. D.C.: 669.018.25 Catangiu
Adrian, Ioniţă Gheorghe, Graţiela Petrişor: Characterisation
of glass/epoxy composite laminates in uniaxial loading Metalurgia (57) 2005, nr. 7, p. 20 This study describes the behavior of a
cross-ply composite under uniaxial tension. The laminate configuration is
(0/902/0). Specimens are cut out of the panels in the direction of
θ = 00, 150, 250, 450 and 900.
Tensile test were performed on the specimens. We observe that there is a very
weak plastic deformation in the fiber direction and nonlinear stress-strain
relations at others angles. |

Radu, NICOLAE Avram: Improvement of cold-rolling parameters
of steel strips dedicated to coating by enamelling technique Metalurgia (57) 2005, nr. 7,
p. 28 The
paper presents an improvement method by a computerized calculus of
cold-rolling parameters of steel strips dedicated to coating by enamelling.
By solver command in the EXCEL program, it is determined the optimum
rolling diagram, by an iterative adjustment of the rolling reduction
coefficients D.C.: 621.43-4; 66.096.1 Ştefănoiu
Radu, Geantă Victor: Systems for inert gas injection
used in the secondary metallurgy Metalurgia (57) 2005, nr. 7,
p. 37 The aim of this paper is to present the
main injection systems used to introduce the inert gases into the ferrous
metallic melts for the secondary treatment. Also, are pointed out some
aspects regarding the factors that influence the injection system design,
installation and using. D.C.: 621.791.75 Agop
Maricel, Mirea Constantin: Teoretical aspects on the stibility of
solid-liquid interface at the electric arc surfacing Metalurgia (57) 2005, nr. 7,
p. 47 Using a coupled equations system for
concentrations and temperatures, the stability conditions of the solid-liquid
interface, in linear approximation, for electric arc surfacing are given.
Particularly, for the undercooled melt, results that this stability depends
both the interface characteristics and the characteristics of the plasma
generated in the column of the electric arc used for welding. |
