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

Краткое описание

An overview is given on the present state and future trends of high power arc heating systems applied in iron and steelmaking, ferroalloys production and dust recycling. As arc generators, metallic torches with cold and hot electrodes are considered as well as graphite electrodes with and without gas-stabilization of the arc.
In practice metal plasma torches are only applied in limited cases to superheat the blast in cupola furnaces and, somewhat more frequently, to heat liquid steel in the tundish. In all other cases the electrode material in high power arc heating systems is graphite. Applications discussed are ore smelting in DC furnaces, submerged-arc furnace production of ferroalloys, stainless steel dust recycling and scrap-based steelmaking.
The production of steel in the electric arc furnace is steadily rising, its share of the total steel production climbing from modest 10 % in 1960 to 35 % in 2000 which will absolutely represent 280 mio t of steel produced in electric arc furnaces (EAFs) with 125 billion kWh or ca. 1 % of the world's annually generated electric power. Operating data of modern AC and DC EAFs are presented and discussed. New trends in furnace design are listed including twin-shell furnaces, scrap preheating and continuous scrap charging installations, DC furnaces with two electrodes and furnaces for high hot metal feed ratios.
