Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.. Increasing amounts are coming from Russia and
its production accounts for about 34% of the total production in the world. With a sharp increase in electricity cost, all ferrochrome producers in South Africa are looking for any alternatives that can use less electricity.

The world's production (supply) and consumption (demand) of chromium have been influenced by the global market, as demand for mineral commodities, including chromium, has increased. Chromium is traded on the world market in the form of ferrochromium, an iron-chromium alloy.
3.3 Energy consumption A good reducibility and especially solid state reduction could help utilising more CO gas for reduction of chrome ore. As illustrated by Figure 4[1], there exists a range of MgO/Al2O3 ratio in slag where its melting point is the lowest corresponding to a minimum of energy consumption for the portion of slag to be melted. This
The lowest specific energy in this work was 5.7 kWh/kg of ferrochrome resulted from using 0.7 of slag basicity. According to Farjadi and Azari [10], the energy consumption in the smelting of ...
In the conventional production of stainless steels, chromium is generally introduced to the process in the form of Cr-Fe-C-Si alloys, principally as high-carbon ferrochrome or charge chrome. The level of carbon and silicon in the above alloys is important especially when refining is …
Experimentally we have found a rational ratio of chrome concentrate, lime and ferrosilicon in a mixture of blended materials, (%): (40-47):(47-43):(13-10), respectively, which ensure the reduction of energy consumption, reduction of melting time and the specified chromium content, lowering the carbon content in the resulting alloy.
Feb 21, 2021· Stainless steel prices up fueled by increase in raw material prices and downstream consumption. The Chinese ferro chrome producers without their own chrome source rely on South Africa to meet 70% ...

The consumption of electric energy required to produce one ton of ferrochrome is in a range 3.30 to 3.34 mwh/t, when the selected 8 different reductants are used. The lowest energy consumption of 3.30 mwh/t can be achieved when using Wankie coke nuts. The highest energy consumption is required when using the selected Chinese coke nuts, seen in
Production of Ferro-Chrome Ferro-chrome (Fe-Cr) is an alloy comprised of iron (Fe) and chromium (Cr) used primarily in the production of stainless steel. The ratio in which the two metals (Fe and Cr) are combined can vary, with the proportion of Cr ranging between 50 % and 70 %.
Due to high energy consumption and continuous depletion of quality raw materials (chromite ore, coke) for production of Ferro-chrome imposed the new challenges for the Ferro-chrome industries to deal with [2]. Therefore, an attempt have been made in the present investigation to optimize the process
Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation's most important strategic and critical materials.
