assembled thicker, you can use pointing and arc welding, assembly because if
the elements are thin, arc welding can lead to burning material. Due to water
ingress into the body through the floor deteriorates corrosion layer material,

In order to estimate proper metallic charge for electrical arc furnace it
was necessary to evaluate iron content in skull delivered from slag dump by
two processors (A and B)
First off all it was necessary to know if the skull from both areas has
the same content or different. Second we had to know histogram for minimum
and maxim values.
As it was taken the decision to include in metallic charge 14 % of skull
(increasing total charge with 2,8 %) with evident economical positive result –
price of scrap is 5 times higher than skull.

43 PROTOTIPAREA RAPIDĂ A UNUI ROTOR PELTON


22-42 STAND EXPERIMENTAL PENTRU CERCETAREA COMPORTĂRII DINAMICE A SERVOMOTOARELOR HIDRAULICE LINIARE ÎN DOMENIUL FRECVENŢIAL

The paper presents the experimental stand used for experimental
research regarding the dynamic behaviour of linear hydraulic servo-motors in
the frequency domain, developed in INOE 2000-IHP, in the framework of the
NUCLEU Program, which allows obtaining of the graphical variation of the
dynamic parameters of servo system.
