Effects of changes in steel industry concentration

The paper on a basis of completed mergers and acquisitions within global steel industry presents changes in steel industry concentration and analyzes its effects on world trade with steel products and on prices of input materials as well as of output products. The analyses performed for the 1990 - 2012 period revealed that increased concentration in global steel industry did not lead to more intensive world trade with steel products; however it is connected with increase of finished products as well as of input material prices

The Influence of Tandem Mill Reduction on Double Reduced (DR) Tinplates Anisotropy

In this paper, influence of tandem mill reduction on double reduced tinplates anisotropy is presented. In order to achieve favourable anisotropy properties (deformation texture) of tinplates for deep drawing operations, optimal percentage reduction on tandem mill is important. The experiment was carried out in laboratory conditions and three sorts of materials (T 57, T 61 and T 65) were used. The anisotropy was classified by earing test determining the ear height of tinplate after deep drawing by measuring the height of any ear. Percentage reduction on tandem mill and final earing relationships of tinplates are researched
