World high carbon ferrochrome production, charge chrome and HCFeCr, was 6.0 million tonnes in 2005. The production increased by 2.8 per cent from the year 2004. Almost all ferrochrome is produced in submerged electric arc furnaces. The raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral.
Jul 10, 2018· Chemical formula of ferro-chrome is FeCr. CAS number of Fe-Cr is 11114-46-8. The density for Fe-Cr varies in the range of 6 grams per cubic centimeters to 9 grams per cubic centimeters depending on its composition. The bulk density of Fe-Cr varies in the range of 3.3 grams per cubic centimeters to 3.7 grams per cubic centimeters.

However, the preferting material is milled high-carbon ferrochrome that is leached in recycled anolyte and make-up H 2 SO 4. A simplified flow sheet showing the essential steps in the process is given in Figure 3-2. The 20-mesh ferrochrome (67 percent chromium) is leached at about 90 °C in roughly 3-metric-ton batches without agitation.
Depending from content of Carbon and Chrome, Ferrochrome can be distinguished to Low Carbon Ferrochrome (LCFeCr, Cr 60-80%, C 0.01-0.5%), Mid Carbon Ferrochrome (MCFeCr, Cr 60-80%, C 1-4%), Charge Chrome (Cr 50-55%, C 9% max) and High Carbon Ferrochrome (HCFeCr, Cr 60-70%, C 9% max). ... white crystalline powder insoluble in water with bulk ...
Soil tests for organic carbon normally report a % total soil organic carbon. Using a measure of bulk density the amount of carbon per hectare in a given depth of soil can be calculated as shown. Calculation. The amount of organic carbon to 10cm depth in soil with a carbon value of 1.5% and bulk density of 1.3g/cm 3 is:
Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy. This slag is formed as a liquid at 1700 C and its main components are SiO 2, Al 2O 3 and MgO. Addi-tionally it consists of chrome, ferrous/ferric oxides and CaO. Present work outlines a .

Apart from making stainless steel, low carbon ferrochrome is also used in the manufacturing of acid-resistant steels. High nitrogen ferrochrome is created by adding 0.75% of nitrogen to the different grades of ferrochrome. This nitrogen-rich alloy is used for manufacturing high-chromium cast steels having a coarse crystalline structure.
The mixtures were preliminary ground in a ball mill in alcohol for 72 h. The high-carbon FKh800 ferrochrome powder (8.6 wt.% C) was prepared by mechanical grinding of the bulk material. The microstructure of the samples was studied using a REM-106I scanning electron microscope.
The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction.The density of quartz is around 2.65 g/cm³ but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm³. In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities (<1.0 g/cm³) due to a combination of ...
The bulk density of a powder is the ratio of the mass of an untapped powder sample and its volume including the contribution of the interparticulate void volume. Hence, the bulk density depends on both the density of powder parti-cles and the spatial arrangement of particles in the powder bed. The bulk density is expressed in grams per mL (g/mL)
High Carbon Ferrochrome Technology ScienceDirect. For high carbon ferrochrome furnaces, electrostatic precipitators are not, however, commonly used, mainly for the following reasons: (1) fineness and high resistivity of the dust from an electric arc furnace can limit the dust removal efficiency, (2) risk of explosion because of high voltage sparking if there is CO in the gas during startup
Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy. This slag is formed as a liquid at 1700 °C and its main components are SiO2, Al2O3 and MgO.
