COMMENT :
Indian aluminium poised for a radical change
Alcastek 2008 concluded last month with flying colours and all round representations from various corners, not only the world aluminium industry, but the Indian aluminium industry at large, covering the various facets such as government policy, user profile, industry structure, financial and physical performance, exports and imports and firm level management issues, and drawing a perspective of the industry.
IN FOCUS
Aluminium-Magnesium - Silicon Alloys
The aluminium-magnesium-silicon system is one of the most important system in aluminium metallurgy. Dissolving and precipitating of the compound magnesium silicide in aluminium forms the basis of 6000 series aluminium.other elements such as
copper.zinc,chromium are added to enhance basic properties of the alloy.
Vedanta pledges US$5 billion aluminium plant near Asansol in West Bengal
West Bengal and Asansol in particular, is all set to firmly entrench itself on the global map s it enters another
phase of industrial development under the dynamic and visionary leadership of its chief minister Buddhadeb Bhattacharjee. By agreeing to set up a large aluminium complex at Bidhanbag, it will be a revival of the first integrated aluminium manufacturing plant in India, which was set up in 1952.
NEWS CORNER
Three-Digit-Million-Euro Order from the Steel Authority of India: Siemens Supplies Turnkey Process Technology for New Cold Rolling Mill in Bokaro
Siemens is responsible for the design, engineering, supply, installation and commissioning of the core lines of the new cold mill plant, which includes a coupled tandem pickling line, a hot-dip galvanizing line and an electrolytic strip cleaning line. The contract also covers installation supervision, commissioning and intensive customer training.
METAL NEWS
Aluminium scrap recycling an Indian perspective
Indian economy is currently on a path of robust growth. Foreign investments, government friendly policies have resulted in GDP growth close to 10%, leading to massive growth in the building, automotive, power, consumer durable and packaging sectors.
TECHNOLOGY/PROCESS REVIEW
From DC cast ingot to finish-gauge rolled sheet
Large scale fabrication of Aluminium sheet is performed in a sequence of processing steps that run from DC-casting, homogenisation, hot and cold rolling, down to final annealing and slitting – depending on the product requirements and customer specifications. In large integrated Al companies the individual process steps are fully optimised and sometimes they even run
in different locations in a most efficient way.
SPECIAL COVERAGE
On massive capacity expansion spree, a success of restructuring
The main operations of the of the Indian aluminum industry is mining of ores, refining of the ore, casting, alloying, sheet, and rolling into foils. At present, Hindalco and Nalco are one of the most economical in the production of aluminum in the world. For the sustenance of the growth the aluminum industry in India has to develop research and development units to assist the production and improve on the quality measures to keep a stringent quality control.
Indian aluminium industry – an overview
Aluminium has now emerged as the second largest metal to be consumed after steel with a total production capacity of around 40 mn MT. This poor man’s silver is replacing steel in a significant manner and reaching the height of applications in several industries including construction, railways, automobile and aviation.
REFRACTORY
Recent advances in refractories aluminate binders and additives for high performance monolithic castables
References indicate that the first “refractory concretes” can be traced as far back as 1856 when H.S.C. Deville prepared a refractory crucible using alumina aggregate and alumina cement1. Calcium aluminate cement and its industrial production were patented by Lafarge in 1908.
SEMINAR & CONFERENCE
Aluminium India 2008, a resounding success
Aluminium India 2008, the international conference and Exhibition came to a close today. Dr. T. Subbarrami Reddy, Union Minister of State for Mines said, "FDI will bring in funds and technology to Aluminium sector". He was speaking at the inauguration of the event.
