Researches of Chemical Metallurgy
Projects pertaining to Alcoa-Köfém Ltd.

Alcoa is the world’s leading producer of primary- and fabricated aluminum and the world’s largest user of bauxite. In addition to the creation of modern day aluminum industry, over the past 125 years, Alcoa innovation have stood behind the all important milestone in aerospace, automotive, packaging, building and construction, commercial transportation, consumer electronics and industrial and commercial markets. Also developed expertise in special fields of industry such as the production of light metals and titanium, nickel-based superalloys. What is more, generates rolled products, extruded hard metal alloys and forged products, such as Alcoa® wheels, fastening systems, precision- and aircraft castings and distributed systems architecture. Alcoa bought a majority stake in Székesfehérvár Alloy Plant in 1993, now is a full owner since 1996. 

The team of Prof. Dr. Thomas Kekesi has done investigations and research several times in the plant of Székesfehérvár.


Our team in the Alcoa-Köfém Ltd.

The very first research topic was in connection with the cleanness of the melt. The research was designed to optimize the degassing equipment in order to achieve maximum efficiency. The modell of degasing have been investigated in industrial circumstances in a framework of a new R&D project. The following research work was much more comprehensive.
Our three-man team investigated the production for more than a month of operation, sometimes in 24-hour shifts. The aim was to set up a full material balance for the melting process. The extraordinary research requested significant contribution from the operating specialists, as well. We had to know precisely the wight of different types of waste being melted, and the weight of alloyers and smelting slag formers. We attempted to determine the amount of residual melt after tapping with a laser based technique.We specified the metal content of Al-alloy drosses in order
to more precisely estimate the so-called ‘sunburn’ loss at the end of the whole material balance.
The evaluation of the collected data has been continued in our institute. The results are well matched to the operating practices and useful for the correct operation of the furnaces. In the Next project we collected slags arising form the melting of different types of alloys, which were treated in our laboratories. We have developed a method to determine the metal content of slags resulting from aluminum smelting. We determined the described the mechanism of slag formation and revealed correspondances between the operation, the slag formation and the metal loss. We made proposals for the Alcoa-Köfém Ltd. based on our results of slag treatment expreiments to become more economical.
