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 Service products

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 blocked

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 and instrumentation.
