Ferro Chrome

Ferrochrome is generally mady by metallurgical grade chrome ore. The main raw material is ferro and chromium.

Categories of ferro chrome alloys:
According to the carbon content in the ferro chrome alloy, it can be divided into three categories.
1Micro-carbon(LC) ferro chrome: C 0.06 to 0.15% and Low-carbon(LC) ferro chrome: C 0.15~0.5%;

2 Medium carbon(MC) ferro chrome: C 0.5~4%;

3 High-carbon(HC) ferro chrome: C 4 to 8%;

Ferrochrome applications

Iron and steel production, especially stainless steel with a chromium content of 10% to 20%, is the largest consumer of high-carbon ferrochromium. More than 80% of the world's ferrochromium is used to produce stainless steel.
Low and medium carbon ferrochrome are used to make special steels. Low carbon ferrochromium can be used to produce superalloys.

Low Carbon Ferrochrome
Low carbon ferrochrome (LC FeCr), with a carbon content below 0.5%, is a ferroalloy used to regulate the ratio of chromium in steel production without adding carbon and other unwanted ingredients. It is also used by the superalloys industries.
Low-carbon ferrochrome, as a ferrochrome variety with low carbon content, is an important additive in steelmaking and casting. Usually, our common stainless steel and high-alloy ferritic steel are smelted by adding low-carbon ferrochrome during smelting. It can be said that low carbon alloys are very widely used.

What is low carbon ferrochrome? Low-carbon ferrochrome is a kind of ferrochrome with a carbon content of less than 0.25. Its raw materials are metallurgical materials such as silicon-chromium alloy, chromite and lime, which are smelted by various smelting methods. Low-carbon alloys are produced in various It is used in all industries, and low-carbon ferrochrome is a necessary ferroalloy additive for the production of stainless steel and special steel in the steelmaking industry.

Generally, ferrochrome will be produced by two production methods: high-carbon ferrochrome refining method and electrosilicon heating method. Silicon reduces chromium and iron oxides in the medium to produce medium and low carbon ferrochrome.

Medium Carbon Ferrochrome
Medium carbon ferrochrome (MC FeCr), with a carbon content of between 0.5-4%, is used in the foundry industry as well as in steelmaking plants where refining capacity is limited but low silicon content is desired.

MC FeCr can be produced by the silico-thermic reduction of chromite ore and concentrates or by the decarburisation of HC FeCr in an oxygen-blown converter. The silico-thermic route is more economic and therefore more important today for producing MC FeCr. This may be because of the low demand for MC FeCr compared to the high demand for HC FeCr. LC FeCr can be produced by the same process.

High carbon ferrochrome

The high-carbon ferrochrome refining method is to refine high-carbon ferrochrome with chrome ore, and can also use oxygen to refine low-carbon ferrochrome. If low-carbon ferrochrome is used in chrome ore concentrate, the slag in the refining furnace has greater viscosity and High melting point, the temperature must be very high during the smelting process, so the power consumption is high, the life of the furnace lining is short, and the carbon content is not easy to drop. If oxygen blowing is used to smelt low-carbon ferrochrome, it has great advantages , There are many advantages, such as high productivity, low production cost, high recovery rate and so on!
