Abstract

Flexibility and efficiency are making steel the material of materials and vitally useful in high tech processes. Steel is fully recyclable; no other material provides currently an equally successful and world-wide applicable recycling process than steel. For the production of the 775 million tonnes of crude steel in 1990, 300 million tonnes (about 40%) had been recovered from scrap material. Environment protection is regarded nowadays by all social groups as one of the most important concerns. The careful use of the environment and its resources is particularly vital to the highly industrialised nations with poor natural resources. From this aspect alone it makes sense to use scrap material in steel production. As modern steel production creates less scrap material due to efficient casting processes, namely extrusion, old scrap material becomes more and more important. For this work, scrap material deriving mainly from used cars and military equipment has been tested and assessed. The impact of metal impurities and associated elements and their effects on the steel properties are described.
The importance for and the impact on the main current techniques (EAF method, converter method) and the newly developed techniques for melting steel (KS and EOF method) are discussed.
