Nicolae: Investigation
on operational characteristics of the modern electric arc furnace
Metalurgia (55) 2003, nr.12 p.5
Recent development regarding
electric arc furnace modernisation required
operation with high values for capacity, productivity and specific power. Optimised and rational operation of such systems requires
compulsory monitorisation of process,
constructional and electrical parameters. Up-to-date evolution of EAF demonstrates that
electrical factors cant be anymore separated of process conditions. In this
respect a new therminology is suggested by authors:
electrotechnological parameters and electrotechnological
regime. Information regarding the analysis of possibilities to operate in
such conditions, are presented in the paper, for a
100 ton EAF.

Paul Ciprian Patic, Ion Florin Popa: Effect of structure and heat treatment on steel
mechinability, both of general purpose and refractary
steel
Metalurgia (55) 2003, nr.12, p.24
Some aspects regarding the main steel elements as iron and carbon, are
presented.
At the same time, different structural constituents, as austenite,
bainite, cementite, ferrite, ledeburite, martensite, pearlite, troostite and
steadite are presented in the paper. Metallic inclusion are, also, treated
accordingly. In the second part, effect of heat treatment on machinability is
largely analysed.
