Growth Story of Aluminium -
The Indian Context
Aluminium is the third abundant element in the earth
crust. It never occurs as a free element. It is a silvery white
metal with a broad range of application in transport,
construction, packaging industry, electronic production,
household appliances, etc., and subsequently the
economic activities of these industrial sectors determine
the overall demand for aluminium.
Aluminium Industry –
Key Growth Drivers
The aluminium industry, being the largest non-ferrous metal industry in
the world economy, is experiencing a period of growth since its industrial
invention, the demand for aluminium has been escalating and its application
has extended to variety of economic sectors. Hence, the performance of this
industry reflects the performance of the economy to a great extent.

HRS Process Systems - ECOFLUX *
Corrugated Tube Heat Exchangers
HRS is the pioneer in introducing
the revolutionary corrugated tube
technology to the process industry.
Corrugated Tube Heat Exchangers are
shell and tube heat exchangers which
use corrugated tubes instead of plain tubes. Corrugated tubes
take the best features of both the plain tube and the plate heat
exchanger. The tubes are corrugated to induce turbulence in
both flows (product & service) at lower velocities. This not only
increases thermal efficiency but also eliminates product
channeling. Thermal efficiency is so improved, that for typical
thin film applications heat transfer area can be reduced to less
than half of that required in a plain tubular heat exchanger.
New developments in Outotec Grinding
Outotec has developed the Outotec hydraulic Inching Drive system to improve
equipment safety and maintenance productivity and the Outotec Barricade for
superior sealing performance.
Copper in Gray Cast Iron
Present work was intended to investigate friction properties, chilling tendency and microstructure changes in Gray Cast Iron (GCI) on addition
of 5, 10 and 15 wt.% Cu. Friction properties were tested using commercial grease LiTioL-24 as lubricant at two disk velocities- 100 and 300 rpm,
under normal load range of 100 N to 2000 N. For comparison of anti-friction properties of GCI and copper-added GCI with bronze, Cu-10 wt.%
Pb was taken as standard material (Std. Mat.). Chilling tendency in GCI and copperadded GCI was studied. Microstructure of materials was
studied under optical microscopy (OM) and scanning electron microscopy (SEM). Copper-added GCI exhibited better anti-friction property in
comparison to GCI and Std. Mat., specifically at 300 rpm disk velocity. Copper addition favoured chilling tendency and it increased with increasing
copper content. It was observed in OM and SEM that copper got alienated out inside GCI forming an intermediate layer at the interface.
Hybrid Tilting Rotary Furnace MASTERmax
for most efficient aluminium recycling
The total amount of Aluminium is constantly increasing worldwide. Therefore, Aluminium recycling
becomes more and more important because recycling of Aluminium does only need about 5% of
the energy needed for primary Aluminium production. The presentation deals with an innovative
concept of tilting rotary furnace, which allows melting of various types of scrap with low energy
consumption and high yields.
Global Bauxite Industry : steady yet
The global bauxite industry is showing prominent signs
of steadiness. As days are passing by, the related market is gaining
momentum and is paving forward effectively. The demand scale
is on a secured path – thanks to its widespread usage as varied
applicators. The pace of demand growth is getting high.
Assessment of High Alumina Refractories
by Phase Diagram Evaluations
Phase diagrams can be very useful tools for the assessment of hot temperature properties of refractories. It does not
require sophisticated computer programs to work with the diagram but only a ruler and a calculator. The paper
describes the benefit of phase diagram work in the assessment of high alumina refractories by selected examples
from high alumina castables for steel applications.
RAFTS-2012: An International Conference on Rolling &
Finishing Technology of Steel
Indian Steel industry is witnessing a phase of expansion
and modernisation of steelmaking facilities to meet the growing
requirements of steel. This calls for adaptation of new
technologies with high-tech engineering, automation and
modelling aids in the steel plants. Rolling Mills being at the
finishing end of the steelmaking process are supplied with
most precision controlled facilities so as to meet the
stringent requirements of the market. Challenge of managing
the operation grows tremendously as the rolling and finishing
lines constitute the longest chain of steel processing. To meet
this challenge, one needs to keep abreast with the latest
innovations in various fields like deformation science, reheating
technology, roll pass design, thermo-mechanical treatment,
descaling, pickling, annealing, coating, modelling, automation
