The November/December of Steel Times International features Minimills and Coating.
The minimill industry has grown from a cluster of scrap based small works established in the 1950s with capacities typically no greater than 300kt/y producing re-bar products to to-day’s minimill groups some of which are now ‘integrated’ EAF works producing several million tonnes a year charging DRI and pig iron with the scrap to reduce the tramp element level sufficiently to produce flat products via the thin slab caster with in-line rolling mill.
Features in this issue look at energy recovery from the EAF, a comparison of vacuum degassing using steam injectors or dry vacuum pumps and a look at the minimill industry in the USA which now produces nearly 60% of its 88Mt of steel in minimills, and – featured on the web site – an article on the various scrap charging scenarios for Tenova’s Consteel scrap pre-heating and continuous charging process.
The Coating feature takes a look at the use of Life Cycle Analysis to compare galvanised utility poles with wooden poles, and special coatings to replace hard chrome with its associated health hazards.
Other features include a report on the recent worldsteel annual conference held in Sao Paulo in October.
The regular News pages, Updates and the History page complete the issue. Also this end of year issue contains the Index of articles and authors for 2013.
This is my last issue as Editor of Steel Times International as I retire after 25 years of association with the title and its sister publication Steel Times.
Thank you all for supporting the title over many years. I am sure my successor, Matthew Moggridge will maintain the standards of this dedicated title to the global steel industry.
The October issue features ironmaking, Safety & Training, a report on the BSE EAF seminar held in Germany earlier in the summer, the competition between steel and aluminium in light weighting automobiles in USA, the use of steel in offshore wind power generation and two articles on India, one lamenting the loss of foreign direct investment on several projects in recent months and the other on a government sponsored campaign to improving energy efficiency in re-rolling mills.
The ironmaking feature includes an article on the use of HBI charged to the blast furnace to increase productivity and reduce the carbon footprint and an article on rapid X-Ray analysis of ore for optimised sinter production.
Regular features include News, Statistics, regional updates on USA, China and Latin America, and the History page from a new contributor, that looks at the delights ‘rusty iron’ can offer the industrial historian.
A feature on the web describes the use of computer simulation during casting – both continuous and ingot − in three French steel mills www.steeltimesint.com/features
The Rolling feature in the September issue looks at the greater precision possible in the product when using of a full frame mill stand rather than housingless for long product rolling, the advantages of updating mills through retrofits and the use of CCD cameras for the detection and diagnosis of mill cobbles.
The stainless and special steels feature examines the use of a combined burner/injector in the EAF for the production of special steels in which the mode of operation differs from their application in carbon steels, reports on the recent stainless steel conference held in New Orleans and a visit to the former ThyssenKrupp plant at Calvert, Alabama and a technical review of the properties of the three main grades of stainless steels.
Other articles include a report on the Steel Success Strategies conference held each year in New York, and how the reintroduction of an import tax on scrap to India has hit the country’s ability to recycle at a critical time of ore shortage.
Regular features are the regional Updates, News, statistics and events, and the History page which commemorates the 50th anniversary of the founding of the Historical Metallurgy Society, based in UK but open to all.
On the web their is a report on two recent Metal Bulletin conferences on iron ore and DRI.
