Since 2005 the Indian economy has been on a tear as it has been growing by over 8 % on average each year. The raw material situation in India and the unique production routes have resulted in remarkable progress in metallurgy, with special technological solutions. That begs the question of whether India will soon increase the production of crude steel as dramatically as China. As part of a study tour in March 2012, members of the Steel Institute VDEh's steelmak-ing committee travelled to several major steel plants in order to obtain first-hand insights into the technology that is currently in use in India. The study tour was kicked off with a seminar on metallurgy at Tata Steel and it included field trips to several major steel plants.

During the last few years the development focus in bar and wire rod production has been definitely the attainment of the desired material properties directly from rolling heat and the possibility of further processing the material without preliminary heat treatment. In combination with free size rolling, this has made production highly flexible. The introduction of near-net-shape beam-blank casting has markedly changed processes in section rolling. The number of passes has been reduced, the rolling mill plants are smaller in size and the rolling process has become simpler, more cost-effective and less energy consuming. Also in section and rail production, objective temperature control and cooling of the rolled product, and in rail rolling additionally the possibility of inline hardening, have led to enhanced product quality.

Since its beginnings in the second half of the 19th century ingot casting technology has undergone a dramatic evolution. After continuous casting was introduced in the 1960s, ingot casting production has concentrated increasingly on large-dimension and niche products, which either cannot be coped with by continuous casting or are needed only in very small quantities. Downhill casting was gradually replaced by uphill casting. Refractory materials and casting fluxes have been substantially sophisticated. The quality and cleanliness of ingots must keep pace wiith the constantly growing requirements. Here modern special remelting processes are of decisive importance, as they have the potential to further improve the cleanliness of cast ingots. The smart combination of the various processes enables steel grades to be produced which, also in the furture, will make ingot casting the only choice in many applications.

Abstract: About 60 % of the crude steel in Europe is currently produced by the oxygen steelmaking process and 40 % by the electric steelmaking process. The product range is of decisive importance for the layout of the steelworks and the equipment for secondary metallurgical treatment. Regarding steelmaking worldwide, thin slabs are increasingly being produced in addition to conventional formats such as slabs, blooms, billets and beam blanks. In order to ensure long-term economic success, however, companies have continuously to develop sophisticated technologies for steel production. Challenges for the future remain in the production of high-purity steel grades, as well as the development of zero-error strategies with maximum productivity and flexibility. This paper summarizes current trends in the development of steelmaking processes. © 2013 Indian Institute of Metals.

In cooperation with Steel Institute VDEh's Committee on Metallurgical Fundamentals, the Chinese Society for Metals (CSM) organized the "3rd CSM-VDEh Metallurgical Seminar" on 17-18 October 2011 in Beijing, China. Along with reports on the progress of the Chinese steel industry and of the VDEh member works, the program comprised latest developments in metallurgy. 130 Chinese experts and 14 from the Committee on Metallurgical Fundamentals attended this top-class seminar. The results of the seminar and of the works visits that followed are summarized below.
