May 2, 2021Ferrochrome (FeCr) slag was milled and stabilised with either ascorbic acid or phosphoric acid. The stabilised FeCr was then geopolymerised with 1 M KOH in order to obtain a monolith with at least an unconfined compressive strength of 1 MPa.
Ferrochrome slag is treated with lime to conduct slag-lime solid-solid reaction. Chromium present in the slag reacts with lime to form mixed chromates. The reaction is conducted at 973K, soluble chromium ion was extracted with water and is subsequently separated by adsorbing fly ash based zeolite which can be recovered. The recovery of chromium metal in the slag is 64%. The method is viable ...

During the production of stain less steel in industries, Ferro chrome slag is produced in process of calcinations at 1700 degree centigrade in liquid state, at certain temperature conditions and then hardened in solid form which is a waste material. Thus the waste material can be used as partial replacement of fine aggregates in concrete.
High Carbon Ferrochrome (HCFeCr) is the most common alloying material used for the production of different grades of stainless steel. World high carbon ferrochrome production was 6.0 Mt in 2005 and the generation of ferrochrome (FeCr) slag, the residue generated from HCFeCr production, amounted 1.1-1.6 t/t FeCr depending on feed materials [ 4 ].

imitating slags of high-carbon ferrochrome, ferrotitanium and high-carbon ferromanganese were made of analyti-cal grade reagents by mixing and melting in a resistance furnace. Slag viscosity was measured with electric vibra- tory viscometer in the temperature range of 0 - 1 800 °C. Based on research results it is recommended to use higher basicity slags together with specific additions ...
Chemical composition of ferrochromium slag can be altered suitably for application in high temperature refractory ceramic application. The use of ferrochromium slag in building and road making material will relieve some of the burden from natural resources. KEYWORDS: Crystal phase concrete environment Ferrochromium slag refractory Acknowledgment
High carbon ferrochrome is an intermediate product and is used as a feed material in the production of value-added materials such as stainless steel. Typical product types for high carbon ferrochrome are crushed lumpy product with a silvery metallic appearance ( Fig. 9.1) and irregular, flaky granulated product with a greenish appearance.
Ferrochrome slag is a by-product from the production of ferrochrome, an essential component in stainless steel. Extensive tests have been carried out on the physical properties of the ferrochrome slag from Vargon Alloys and it was found to be highly suitable as road construction material.

Ferrochrome Slag Aa 7075 7075 Alloy Present studies are based on adding ferrochrome slag as reinforcement in AA 7075 alloy manufactured via the stir casting process. Two different slag particles are chosen; they are 36μm (Micro) and 68 nm (Nano). This was added to evaluate the size effects in the given alloy matrix.
Bring to a boil and, dropwise, add 10-pct stannous chloride solution, with mixing, until the solution is colorless. Add 3 to 5 drops excess and just bring to a boil again. Cool to room temperature or below, and add 10 mL of a saturated solution of mercuric chloride: mix, and add 10 mL of concentrated phosphoric acid.
Ferrochrome slag (FS) is another residue that is obtained as a solid waste by the smelting process during the production of stainless steel in Ferroalloy industries.

Ferrochrome (FeCr) slag is a waste product from the carbothermic reduction of FeCr ore resulting in the production of high or low carbon FeCr alloy. It is estimated that the global annual production of FeCr alloy is between 12 and 16 Mt [ 1 ]. It also is estimated that the FeCr slag to alloy production is 1.1-1.5:1 [ 2 ].
For the carbon steel slag, originating from an EAF, three particle sizes were studied (0-5 mm, 20-40 mm, 40-185 mm). The ferrochrome slag was crushed and sieved to a 4-9 mm fraction. The stainless steel slag is a finegrained fraction (< 500 µm) obtained after a crushing, screening and demetallisation treatment. For the characterization
