The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

RÉSUMÉ

Steelmaking in the electric arc furnace (EAF) has been and continues to be a strongly expanding technology. Its share of the world's total steel production has been growing from 10 % in 1960 to 22 % in 1980 and to 33 % in 1997 and will eventually reach 40 %. Starting off as a mere scrap melting process, the EAF technology has become much more flexible with regard to input materials including direct-reduced iron, iron carbide and hot metal, and with respect to input energies like gas, oil and coal in addition to electric power. A great number of different inprovements concerning process technology and furnace components have contributed to the EAF sucess story: Ultra-high power technology, foaming slag practice, water-cooled roofs and walls, improved graphite electrodes, the DC technology, scrap preheating, twin-shell furnaces, and sophisticated process control. The expansion of the EAF technology has recently been boosted by the development of thin slab and strip casting machines which opened the way to mini-mills for flat products. Further improvements might be achieved by injecting molecular gases into the arcs leading to higher arc voltages and - at constant power - to lower arc currents which would in turn reduce the graphite electrode wear.
