The Processing Of High Carbon Ferrochrome
Ferrochrome (FeCr)
It is produced in an energy intensive process in electric furnaces from chrome ore, iron ore and coal. FeCr is used in the production of stainless steel, special steel and castings. Ferrochrome is divided up in three main products which are Low Carbon FeCr, Medium Carbon FeCr and High Carbon FeCr. Physical Properties . General . The melting point and density of ferrochrome depends on its ...

Lowcarbon ferrochrome for superalloys (SA) is the culmination of JFE Materical's outstanding ferrochrome manufacturing technologies. ① Cr component is stabilized at a high level of 68 to 70% by using a combination of raw material treatment technology and electric furnace smelting technology.
Usage
Ferrochrome is often classified by the amount of carbon and chrome it contains. The vast majority of FeCr produced is charge chrome from Southern Africa. With high carbon being the second largest segment followed by the smaller sectors of low carbon and intermediate carbon material.
Ferroalloys
Ferrochrome. Ferrochrome, also known as ferrochromium, typically consists of 50 to 70 % of chromium by weight. Basically, it is an alloy of chromium and iron. Ferrochrome is mainly used in the production of steel, which makes up for about 80 % of the world's consumption. In general, ferrochrome is produced in an electric arc furnace. The production process is essentially a carbothermic ...
