The three types of ferrochrome alloys are: High-carbon (HC) ferrochrome (carbon content between 4% and 9%) Low- and medium-carbon (LC & MC) ferrochrome (carbon content less than 0.5% for LC and between 0.5% and 4% for MC) Ferrochrome-silico-chrome (FeSiCr) Ferrochrome applications.
1. Introduction. Ferrochrome slag is a by-product of the production of ferro-chrome alloy, an essential component in stainless steel. The conventional process of ferrochrome making involves the carbothermic reduction of chromite ore where around 1.2–1.5 tons of slag containing approximately 8–12% of chromium oxide is generated …
Ferrochrome (FeCr), a relatively crude alloy comprised primarily of iron (Fe) and chromium (Cr), is vital for the production of stainless steel. FeCr is produced from chromite ore, the most important source of Cr units. FeCr producers are only paid per mass unit of Cr content in the FeCr, i.e. in US¢/lb contained Cr, according to the ...
Smelting Ferrochrome 1 Introduction Chromium is one of the essential raw materials for the production of ferrochrome/charge chrome alloys. World reserves of chromite ore are estimated to be 6500Mt. The total Indian reserve/resources are estimated to be around 344 million tonnes, which accounts for 2.5% of the world reserve [1].
Fine-grained ferrochrome alloy. Ferrochrome Slag Processing Projects. The ferrochrome smelting slag is crushed by a coarse-jaw crusher, which crushes large pieces of material into small pieces, and then enters the fine-jaw crusher to be crushed again. Due to the high hardness of the ferrochrome smelting slag, only the jaw …
Ferochrome slag Jig machine. In the ferrchorome slag jiggng process, the main separation machine involved is the ferrochrome slag jig machine.Jig machine is a compact and efficient gravity separation device which is widely untilized throughout the world.The jig machine has many advantages such as high recovery, high unit …
