high carbon ferrochrome iron fertilizer ball mill

Production. Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore an oxide of chromium and iron is reduced. The Aluminothermic Plant will see ACF processing about 300 tonnes of ultra low carbon high grade ferrochrome per month, with production set to reach 600 tonnes monthly at its peak.

Jun 01, 2014 In high carbon ferrochromium, metallic Cr content is 60–65% with varying amounts of Fe and C. Ferrochromium is produced pyrometallurgically by carbothermic reduction of chromite ore (FeO Cr 2 O 3). The main raw material in the production of ferrochrome is chromite, which is basically chrome and iron oxides containing mineral.

The chromite ore used for smelting ferrochrome is generally required to contain 340 to 50% of Cr2O. The ratio of chromium to iron is greater than 2.8. Ferrochromium alloys are classified into high carbon ferrochrome, medium carbon ferro chrome, low carbon ferrochrome, and micro carbon ferrochrome according to the difference in carbon content.

Dec 10, 2016 High carbon ferrochrome slag is a byproduct of High Carbon Ferrochrome (HCFeCr) production in submerged arc furnaces. The slag is conventionally tapped from the furnaces and granulated before being dumped as waste. The major uses of the slag have been in road and civil engineering construction and in production of refractories.

Jan 01, 2013 High carbon ferrochrome does not have a single specification, as the ores in different regions differ, which impacts on certain components in the alloy (e.g., Cr, Fe, and C). Furthermore, the smelting process (slag metallurgy or technology route) employed also impacts on particular components in the alloy (e.g., Si, S).

High carbon ferrochrome (HCFeCr) alloy is the main source of chromium in steel making processes. During the production of high carbon ferrochrome alloy, in ferrochrome smelters, a substantial amount of slag is produced. These slags are generally disposed of in slag dumps or containment facilities causing environmental and containment problems.
