1) PROCEDURE FOR THE RECOVERY OF THE SALINE DERIVATIVES
COMING FROM CLEANERS OF NON FERROUS METALS REFINERIES.
The general scheme foresees different solutions, from the
fusion to the by-pass, also in a opportunely correct manner,
of saline dumps coming from the downstream damping plants of
the melting cycle.
2) CONTROL OF THE CELLULAR STATE OF THE GRAY CAST IRONS
WITH ADDITION OF RARE EARTHS.
The trace elements, or also secondary elements constitutionally
present in flake cast iron, for instance the bismuth, can alter
sensitively the dimensions of the eutectic cells, and therefore
their number for unity of surface, with all the consequent defects,
micro-shrinkage defects included. The addition to the bath of
rare earths derivatives opportunely selected, allows to cancel
these interferences of difficult control.
3) PROCEDURE FOR THE CONTINUOUS CASTING OF STEELS.
Boron based steels; controlled grain austenitic steels and
balanced steels, with this procedure are poured in continuous
line without incurring in the obstruction problems of feeding
apparatuses. The quality of the produced steels results particularly
elevated.
4) FUSION PROCEDURE WITH ROTARY OR FLAME DIRECT STATIC
FURNACES.
Once found the origin of the thermodynamic and kinetic chemical
mechanisms that compromised the useful life of the refractory
masses, as well as the quality of the produced irons, the procedure,
already economic in the calculation of the combustible and comburent
gas consumptions, has decupled the resistance of refractories
as well as it has removed the qualitative limits of the produced
irons, from the flake to the spheroidal ones.
PATENT EXTENSION
Recovery of thermal energy connected to the gaseous mass of
combustibles and its use for the fluids heating of current use.
5) LITHIUM AND RARE EARTHS BASED DEOXIDIZERS FOR STEELS.
By completing the aluminium with lithium, calcium, titanium
and rare earths, can be reached levels of deoxidation; of inclusional
morphology modification; of bath detergency and liquid flowability
definetely higher.
6) CERAMIC FILTERS FOR THE POURING OF IRON CASTINGS.
A special geometry allows to prevent the slide of pre-melted
inoculant blocks placed in the mould, solving the problems of
automatic joining of the two half moulds on the bottom of the
automatic lines, as well as can answer to the necessity of correcting,
inside the mould, the structural configuration of castings simultaneously
poured.
7) ELABORATION OF NON FERROUS ALLOYS WITH RARE EARTHS.
Alloys for modification interventions; for the de-gasing and
macro-structural refining; to increase the smoothness, and then
lower also the working pressure in die-casting, even exalting
the technological characteristics of finished parts.
8) NUCLEANTS FOR CAST IRONS ALSO FOR HYPEREUTECTIC IRONS.
In the field of the high equivalent-carbons, the answer to
the inoculation is always precarious or insufficient. With the
nucleation prestigious matrixes and molds of A type graphitic
phase are assured.
9) LIQUID STATE ELABORATION OF THE ELECTRIC FURNACE PRE-MELTED
CAST IRONS.
The adding to the bath of particular metallic ions allows
to modify the nature of fluid slags of hardly flotation, trigging
at the same time a strong nucleant capability of the cast iron,
a long time effect.
10) PROCEDURE FOR THE PRODUCTION OF IRON SAFETY CASTINGS.
Fruit of a long industrial experimentation, the procedure
involves the production of castings with lines of high automation.
