Low Carbon Ferrochrome Production (LC FeCr) LC FeCr (Low Carbon Ferrochrome) is a ferro-alloy used to regulate the ratio of Chromium in steel production without Carbon and other unwanted ingredients. Due to high quality it is a reliable and economical alternative instead of metallic Chromium in Superalloy production
World high carbon ferrochrome production, charge chrome and HCFeCr, was 6.0 million tonnes in 2005. The production increased by 2.8 per cent from the year 2004. Almost all ferrochrome is produced in submerged electric arc furnaces. The raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral.

high carbon ferrochrome (HCFeCr) in submerged are furnace (SAF), which uses electric energy and is fed with raw materials of chrome ores, fluxes, reductant and electrode paste. The Ferrochrome Simulation is developed using the principles of mass balance and .
When chromite and lime are melted in an open electric-arc furnace and then contacted with ferrochrome silicon, a low-carbon (0.05 percent) ferrochromium can be obtained. In an alternate process, high-carbon ferrochromium is oxidized and then blended with additional high-carbon ferrochromium.
Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.Increasing amounts are coming from Russia and China. Production of steel, especially that of stainless steel with chromium content of 10 to 20%, is the largest consumer and the main application .

Smelting process of high carbon ferrochrome. The smelting methods of high carbon ferrochrome include a blast furnace method, an electric furnace method, and a plasma furnace method. Only blast furnaces can be used to produce special pig iron with about 30% chromium. As of 2012, high-carbon ferrochrome with high chromium content was mostly ...
Medium-carbon ferrochrome is also a product of interest in the foundry industry and in steelmaking plants where refining capacity is limited but low silicon content is desired. Most of the medium-carbon FeCr is produced by the oxygen-converter method. It is based on carbon removal from liquid high-carbon ferrochrome (8% to 9% C, 0.3% to 0.5% Si, 0.04% P) with gaseous oxygen blowing .

Jan 01, 2013· High carbon ferrochrome is primarily used in the production of stainless steel. More than 90% of high carbon ferrochrome is used in the production of stainless steel (International Chromium Development Association [ICDA], 2011). The majority of the balance is used in the manufacturing of special steels (including high chromium steels). 9.2.
A process for producing high carbon ferrochrome which consists of feeding continuously to an electric furance a charge mixture consisting of sintered pellets containing substantially no free carbon, which pellets have been obtained by the partial reductive calcination of chrome ores, and a carbonaceous material of particle size 20 - 100 mm; and submitting this charge mixture to a continuous ...
The conventional process for producing high carbon ferrochromium by smelting chromite ore in a submerged arc furnace is reviewed and its limitations highlighted with regard to (a) product quality through impurity removal, and (b) high power consumption for a given raw materials supply.

chromium processing: High-carbon ferrochromium Most ores smelted with coke in an electric furnace produce metals that are saturated with carbon. For ferrochromium, the saturation point is approximately 9 percent, but actual carbon content varies with the condition of the ore and the composition of the slag.
A part of the ground high-carbon ferrochrome is oxidized and calcined as an oxidizing agent, and is added with water glass or other binder to form agglomerates. After being dried at a low temperature, it is heated and reduced in a vacuum of 0.5 to 10 mmHg at a temperature of 1300 to 1400 ° C for 35 to 50 hours in a vacuum furnace.
