What is ferrochrome? Ferrochromium is made using metallurgical grade chrome ore and can be divided into three categories, depending on the level of carbon in the alloy. 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: Production of steel, especially stainless steel with chromium content of 10 to 20%, is the largest consumer of high-carbon ferrochrome. Over 80% of the worldâ??s ferrochrome is used in the production of stainless steel. The vast majority of ferrochrome produced is� charge chrome, which has a lower chrome content ratio. Used most commonly in stainless steel. Low carbon� and� medium carbon� ferrochrome is used in the manufacture of special steels. Low carbon ferrochrome can be used to produce superalloys.

Chrome Ore The only ore of chromium, the metal used to make stainless steel, nichrome and chrome plating. What is Chrome Ore? Chrome Ore is an oxide mineral composed of chromium, iron and oxygen (FeCr2O4). It is a dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when Chrome Ore-bearing rocks are altered by heat or weathering. Chrome Ore is important because it is the only economic ore ofchromium, an essential element for a wide variety of metal, chemical and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium. Properties of Chrome Ore Chrome Ore can be challenging to identify. Several properties must be considered to differentiate it from other metallic ores. Hand specimen identification of Chrome Ore requires a consideration of: color, specific gravity, luster, and a characteristic brown streak. The most important clue to identifying Chrome Ore is its association with ultrabasic igneous rocks and metamorphic rocks such as serpentinite. Physical Properties of Chrome Ore Chrome Ore is sometimes slightly magnetic. This can cause it to be confused with magnetite. Chrome Ore and ilmenite have very similar properties. Careful observations of hardness, streak and specific gravity are required to distinguish these minerals in hand specimens.
Chrome ore is also called the chromite sand, is a special foundry sand, natural spinel, of chromite on particle size by crushing, grinding, screening regulation, applicable to modelling (core) sand.Chrome ore according to the chemical composition is divided into level 2;level 1 cr2o3 45% or more;the secondary cr2o3 35% or higher.Chrome ore in casting production is mainly used for large steel surface sand, prevent casting surface adhering sand;secondly the grinding powder used in casting coating refractory aggregate;chrome ore is chilling material, when modelling (core) alternative part cold iron. For drainage sand materials, casting, ceramic, glass and refractory, etc.Chromite sand applicable types: casting grade is special, special metallurgy level.Chrome ore in casting production is mainly used for large steel surface sand, prevent casting surface adhering sand;secondly the grinding powder for the refractory aggregate of foundry coating, chrome ore is chilling material, when modelling (core) alternative part cold iron.Chromite sand for casting coating, refractory materials, brake pads, high-performance ceramic materials, ceramic and glass colorant, friction material, chemical and metallurgical casting, etc.
