(1) The cold crushing strength of ferro-coke decreased with the increasing amount of iron ore. When the addition amount of iron ore was 20%, the cold crushing strength of ferro-coke was 72.11%. However, when the amount reached 30%, the cold crushing strength of ferro-coke dropped to 18.15%.
with slag mold exhibited excellent surface finish, less surface defects and porosity. Murthy et al.16,17 conducted a study on the use of ferro chrome slag as a mold material. Their investigation revealed that casting with a ferro chrome slag mold facilitated faster heat transfer, resulting in castings with improved metallurgical and mechanical ...
The present study was aimed at highlighting the effect of silica on chromium distribution and enrichment in certain stainless-steel slag when basicity ranged from 0.96 to 1.96. Industrial slag samples of the CaO–Al2O3–MgO–SiO2–CrO X –Fe X O system were investigated with different silica addition contents and soaked at the targeted regime. X-ray diffraction, …

The beneficiation process can include crushing, screening, and gravity separation to concentrate the chromite. 2. Smelting. ... Ferrochrome slag. Ferro chrome slag results as a byproduct generated during the production of ferro chrome, usually through the smelting of chromite ore in electric arc furnaces. This slag consists of various non ...
After simple crushing and sieving, ferrochrome slag with a particle size larger than 4.75 mm is used as coarse aggregate, while those smaller than 4.75 mm are used as fine …
Ferrochrome slag is a by-product from the production of chrome. There are environmental and economic advantages in seeing slags as a potentially useful resource rather than as waste products. Slag management at ferrochrome producing companies has been influenced by the limited space available and financial cost implications of the slag dumps.
Research on the use of Ferro-Chrome slag in civil engineering applications Khalifa S. Al-Jabri ... Crushing Value (%) 17.89 20.10 Abrasion Resistance (%) 18.19 18.60 ... effect of FeCr slag on the properties of cement mortars and concrete. These studies were focused mainly on the
The result shows that the mold properties of blast furnace slag were better as compared to silica sand mold; the mold properties such as shear strength, compressive strength, hardness and ...
Ferrochrome (FeCr) is the main source of chromium (Cr) units used in modern-day chromium (Cr) containing alloys. The vast majority of produced Cr is used during the production of stainless steel, which owes its corrosion resistance mainly to the presence of Cr. In turn, stainless steel is mainly produced from Cr-containing scrap metal and FeCr, which is a …
Free silica phase was found to increase with increasing microsilica content in an order as follows: castable S5 < S 7.5 < S10. At 1300 °C it was found that the major crystalline …
Various efforts are being made to use industrial wastes as an alternate moulding material in the foundry industry. Ferrochrome (Fe–Cr) slag has many of the same attributes of …
Ferrochrome slag (FCS) is a by-product of ferrochrome industries and is produced during the extraction of ferrochrome from chromite ore. The chemical composition of FCS comprises of 27–33% SiO2 ...
Virtually all charge chrome plants now use the crushing/jigging process to recover chrome alloy from both stockpiled and currently produced slag. Studies were carried out at R&D, Tata Steel to develop a flow sheet for the recovery of metal from metal–slag mix generated in its charge chrome (ferrochrome with 50–60% chromium) plant, Bamnipal.
In the present investigation efforts are made to use Ferro chrome (Fe-Cr) slag as mould material for replacement of silica sand in foundry industry. Sodium Silicate- Fe-Si process is adopted for ...
Ferrochrome slag that has been water-cooled is present in granulated form with grain sizes that are similar to natural sand. Ferrochrome slag is a derivative of the …
The ferro-chrome slag passed through 4.75mm and retained in 1.0 mm IS sieves, is used and mixed with the silty soil in different ratios by weight (10:90) to (60:40), to find out the most suitable ...
The influences of silica fume (SF) on the properties of sodium silicate-based alkali-activated slag/glass powder (AASG) pastes were systematically investigated. Evaluation of fresh properties (including setting time, flow spread, and rheological behavior) and compressive strength of AASG pastes were carried out.
For example, blast furnace slag, a type of ISW, is a by-product of iron obtained in steel making industries and widely used in cement and concrete industries (Silva et al., 2023).

Ferro-nickel slag (FNS) is a byproduct of the ferro-nickel from the nickel ore refinement process. Following the preliminary reduction process at temperatures ranging from 700 to 800 °C, FNS is produced when the nickel ores are melted at temperatures between 1500 and 1600 °C in an electric furnace and the byproducts are cooled in water or air.
