Future outlook for the FerroAlloys industry

2.6 Future outlook for the FerroAlloys industry Progress in the ferroalloys industry has closely followed developments in the steel industry, and this course will continue. The rapid growth in stainless steel use has driven a corresponding growth at least for chromium (FeCr) and nickel (Ni, FeNi, NiO): the average annual growth rate in this sector has been more than 5%. The demand for stainless steel has increased, particularly in China and India, the two largest countries by population. Such growth...

Energy and emission issues of the FerroAlloys

2.5 Energy and emission issues of the FerroAlloys 2.5.1 Energy Demand for Ferroalloys Making Today’s ferroalloys are almost always produced by smelting in electric submerged arc furnaces (SAFs); only a comparatively small amount of ferromanganese is still produced in blast furnaces. A conventional SAF is an open furnace from which off-gas is mixed and combusted with a large amount of air. A “closed furnace,” however, is designed to maintain CO-rich off-gas by collecting, cleaning, and storing it for further utilization. An...

Recent FerroAlloys production and markets

2.4 Recent FerroAlloys production and markets DEVELOPMENT As the ferroalloys are primarily used in steelmaking, different grades of alloys have been developed to fulfill the varying requirements of the steel industry. As discussed earlier, most of the chromium is added in the form of high-carbon charge FeCr (50% to 55% Cr, 2% to 5% Si, 6% to 8% C, and the balance is Fe). Also, for different alloying purposes, different Cr-alloys are produced with higher Cr and lower carbon contents than in...

2.3 Ferro Alloys for stainless steel

Among high-alloyed steels, stainless steels are a special case because of their large production amount and central position as users of ferrochromium. Furthermore, other ferroalloys are also used extensively for stainless steel production. The history of stainless steel is quite short, as the effect of chromium on the improved corrosion resistance of iron was only recognized in the early 1800s. However, at that time it was not yet possible to produce chromium or chromium ferroalloy had to be produced industrially....

2.2 FerroAlloys in the development of steels

As mentioned, old historical iron artifacts were made of almost pure iron containing only carbon as the alloying element. Properties like hardness, strength, and toughness were controlled by changing carbon content with the use of carburizing or decarburizing treatments, skills that had been mastered by blacksmiths. Historical “super steels” like “Damascus” steel and “Bulat” steel, which used Indian “Wootz” iron as a raw material, had amazing properties that are difficult to attain with modern technologies. Rather, in these steels...

2.1 Introduction: Background for FerroAlloys

BACKGROUND FOR FERROALLOYS DEVELOPMENT AND PRODUCTION The history of ferroalloys is relatively short compared to bronze or iron development. Ancient iron artifacts investigated are mostly fairly pure iron, containing carbon as the only alloying element. Carbon control by carburizing/ decarburizing treatments was traditionally understood by blacksmiths and was used throughout the “Iron Age” to adjust steel properties. Steel produced via the direct reduction route in bloomeries remained naturally unalloyed because iron oxide was reduced at such low temperatures that iron was...

1.1 Introduction to Ferro Alloys

  Ferroalloys (and master alloys in general) have been developed to improve the properties of steels and alloys by introducing specific alloying elements in desirable quantities in the most feasible technical and economic way. Ferroalloys are namely alloys of one or more alloying elements with iron, employed to add chemical elements into molten metal. Not a single steel grade is produced without ferroalloys (Wood and Owen, 2005). Ferroalloys production is an important part of the manufacturing chain between the mining and...
