Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy This slag is formed as a liquid at 1700 176 C and its main components are SiO 2, Al 2 O 3 and MgO Additionally it consists of chrome, ferrous/ferric oxides and CaO...
Foundry-grade ferrochrome containing around 62-66 chromium and almost 5 carbon is used for producing cast irons Ferrochrome powder is used in the field of powder metallurgy Ferrochrome slag is a chemically stable substance It is used in road construction and civil engineering as well as in the production of refractory materials...
The disadvantage of this method is to divide the process of melting the oxide part of the charge from the process of recovery of the oxides of chromium, because the additive is a reducing agent-ferrochrome silicon is produced after melting the mixture of the ore with lime, which leads to increased consumption of heat the use of chrome ore ....
In ferrochrome smelting operations, the manganese should find its way into the slag rather than the metal Data from these analyses have most often been used to trace the partitioning of the manganese through the smelting process and for material balance calculations...
Ferrochrome smelting slag gravity separation technology Ferrochrome smelting slag is also known as ferrochrome slag and chromium slag, etc, are produced by the smelting ferrochrome solid waste residue Ferrochrome slag is mostly solid dry slag, hardness is very big, is gray black, according to the different of smelting process, ferrochrome smelting slag containes different chromium iron ....
323 Ferrochrome slag pH Ferrochrome slag pH was measured as per the method outlined in ASTM Method 9045D 6 To 20 g of waste sample in a 50-mL beaker, 20 mL of reagent water was added The samples were covered, and continuously stirred and were kept in suspension for 5 min...
