Worldsteel benchmarking systems
The World Steel Association (worldsteel) represents over 160 steel producers (including 9 of the world’s 10 largest steel companies), national and regional steel industry associations, and steel research institutes. worldsteel members represent around 85% of world steel production. worldsteel acts as the focal point for the steel industry, providing global […]
Mini mills, Micro mills, Nano mills and the Energy Saving Compact Mini mill
World electric steelmaking has increased from 595Mt in 1960 to 1,606Mt in 2013, an increase of 170% and, since their beginnings in the 1970s, a typical mini mill has increased its output from 0.50 to 3.0Mt/yr. At the same time, market requirements for regional production using local raw materials (within […]
Comparative vacuum performance calculations of mechanical booster pumps
Mechanical dry vacuum pumps are increasingly replacing traditional steam ejectors in vacuum secondary steelmaking plant applications because of their ‘greener’ credentials. It is extremely important that accurate prediction of mechanical booster capability is made, otherwise the vacuum system, when delivered, may not meet the user’s requirements, forcing changes to process […]
Processing of high strength hot rolled strips through the Thin Slab Casting and Rolling facility of TATA Steel, Jamshedpur
Thin slab casting and rolling (TSCR) also known as Compact Strip Production (CSP), was developed by SMS Semag® for the production of hot rolled strip in a compact production line. Although soft unalloyed grades were the first TSCR products, the technology has been successfully used for the production of HSLA […]
Danieli Universal Endless – DUE® – technology and latest installation in P R China
Over the past 25 years the thin slab casting and rolling process has been gaining a major market share in the production of hot rolled strip, progressively eroding the areas previously the exclusive domain of conventional mills. Danieli has progressively developed a new generation of thin slab casting and rolling […]
Achieving EAF environmental and process synergy with Tenova Technologies
Technologies and tools exist that can achieve synergy between the EAF process and reduced environmental impact. The important principle is to combine all technologies into a single operating system and ensure balanced production operations. By using Tenova’s proprietary EFSOP® as the cornerstone for process optimisation, steelmakers can be confident of […]
XuperCoatTM mould coatings for improved wear resistance and product quality
Mould coatings play a crucial part in improving product quality and reducing operating costs in continuous casting. Monitor Coatings, a UK-based Castolin Eutectic company, has developed a unique ceramic composite coating technology, XuperCoat™, which has produced best-in-class results in terms of mould life, cast product quality and caster operating costs. […]
Increased productivity and quality through conversion of secondary cooling to air-mist system on beam blank, bloom and round combi caster
The 4-strand combi caster at SMS-II of Jindal Steel & Power Ltd commissioned in 2003, was designed to produce two beam blank section sizes, two bloom sizes and four sizes of rounds. As demand increased and the product range extended, caster productivity, casting speeds and product quality did not meet […]
Start-up and operation of the world’s most powerful hot strip mill at ATI
On 18 March, 2014, a new, fully integrated hot-rolling and processing facility (HRPF), supplied by Primetals Technologies on a process-turnkey basis, was started at the Brackenridge facility of Allegheny Technologies Incorporated (ATI) in Pennsylvania, USA. The mill is capable of rolling up to 3.5Mt/yr of a broad range of highly […]
Double regenerative burners for reheating furnaces: an innovative concept to substantially improve energy efficiency
CMI’s patented Double Regenerative Burner (DRB) technology for reheating furnaces considerably lowers CO, CO2 and NOx emissions, while at the same time allowing the replacement of natural gas by less expensive blast furnace gas, despite its low calorific value.
