Abstract

Final report on Contract No 7210-CB/313, 944, 1 July 1996 to 30 June 1999.

The present investigation has been targeted at reinforcing the methodology for monitoring scrap quality and at establishing a large database on the quality of scrap in western Europe. Two main methods have been investigated and perfected in detail, the statistical analysis of steel-shop heats and melting tests of scrap. They both provide an overall view of the quality of scrap on the market and make it possible to establish a quality insurance relationship with suppliers.

The limits of the methods have also been investigated. Thus it is impossible to obtain information on the spread of composition data or on yield from statistical analysis, or to measure electricity consumption of a given scrap category by melting tests. However, used together, these methods produce all the information that is required to estimate the in-use value of scrap.

The overall picture of scrap quality that emerges from the database is complex. First, the scrap industry has demonstrated its ability to meet the requirement of the European scrap grading system. However, a few suppliers still deliver poor quality material that "pollutes" the global picture. Moreover, it takes time for the suppliers to adjust to the quality insurance system, so those who have been using it longer demonstrate better performance. Finally, E40 shredded scrap has not, on average, complied with the requirements of the ESGS, although a few suppliers know how to produce high quality.
