Low carbon ferrochrome (LC FeCr) is a ferroalloy with low carbon content, widely used in the production of stainless steel and other special steels. As an important metallurgical material, low carbon ferrochrome not only enhances the corrosion resistance and strength of steel but also excels in energy conservation and emission reduction. This article will discuss in detail …
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% SiO 2, 15–25% Al 2 O 3, 20–35% MgO, and 10–15% iron-chromium compounds.The high chromium content of FCS and the possibility of its leaching into the …
The chrome ore sinter thus produced was found to be inferior in strength, comparable to that of an iron ore sinter, but strength requirements may not be the same for both. Because the heat generation during chrome ore sintering is high owing to some exothermic reactions, compared with iron ore, and because chrome ore contains a high amount of ...
The requirement to use all lumpy ore has been circumvented to a large extent at Zimbabwe Alloys. The use of briquetted chrome ore fines in the production of Ferrosilicon Chrome and High Carbon Ferrochrome has yielded positive results over a period in excess of twenty-five years.
