Product Description:

 

Description 

 Ferro Silicon  alloy is one of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke, quartz 

(or silica) as raw materials and is made by electric furnace. 

Features 

 1. Fesi 75% is often used as deoxidizer in steel plant.   

2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel. 

3. It can be used as a reductant in ferroalloy production and chemical industry. 

4. In iron industry it can be used as inoculant and nodulizer.

Q:What are the major differences between ilmenite and ilmenite?
Ilmenite generally refers to ore (i.e. after mining without dressing, impurities in the ore), namely ilmenite, more professional means that H2TiO3 titanium (FeTiO3). Ilmenite is an oxide mineral of iron and titanium and is the main ore for refining titanium. Ilmenite is heavy, gray to black, with a metallic luster. Crystals are usually plate shaped, and crystals are arranged together in clumps or granules.
Q:How did the sedimentary pyrite form?
This effect is often part of the outcrop in metal oxide deposit with the formation of limonite or goethite, lepidocrocite covered in ore body, so called gossan. Jarosite can be formed under the condition of strong acidity of oxidation zone, and its distribution is only inferior to limonite.
Q:What is the difference between iron ore in different countries? Which is the best and the worst?
The supply of iron ore in China mainly comes from four major suppliers in two countries, namely, CVRD group in Brazil, BHP Billiton group in Australia, Rio Tinto Group and FMG group
Q:The difference between iron ore and iron ore
Iron ore: iron (Fe) exist in nature, pure iron does not exist in nature, iron ore mainly consists of magnetite, hematite, limonite, three, these are iron oxides, the difference lies in the way of their oxidation. The higher the iron content in the iron sand, the highest iron content in the iron ore is about 72%, and the iron content is more than 60%, which is called "rich iron ore".
Q:Characteristics of hematite
The chemical composition of hematite is Fe2O3, and crystal is an oxide mineral of three square system. Similar to that of equiaxed magnetic hematite. Crystals are usually plate-like; aggregates are usually flaky, scaly, kidney like, oolitic, blocky, or earthy. A reddish brown, steel gray to black color, streak are cherry red. Metallic to semi metallic luster. Moss hardness 5.5 ~ 6.5, specific gravity 4.9 ~ 5.3. It is iron black, metallic luster, flaky hematite called border iron ore; a steel gray, metallic luster, scaly called mica hematite, Chinese called "cloud" iron; reddish brown earthy luster dim called ochre, Chinese called "Dai zhe", and to "" refers to the ochre hematite.
Q:Is pyrite the pyrite?
It's the same kind of ore. The main ingredients are FeS2
Q:What is pyrite used for?
The most common crystals of pyrite are six - body, eight - body and five - angle, twelve - body. There are fine stripes on the crystal faces of six square crystals. Sometimes many crystals join together to become a variety of polycrystalline crystals. Sometimes a golden yellow, sometimes brass, and Huang Liang Huang Liang, with a metallic luster. Specific gravity 4.95 - 5.20. Hardness 6 - 6.5. Green black streak. Brittle, easily broken by beating, and broken surfaces are uneven. When burning blue flame and a pungent smell of sulfur:
Q:How many operations are required from iron ore to steel?
Iron ore: the main raw material for iron smelting, magnetite, Fe3O4, hematite, Fe2O3, limonite, 2Fe2O3.3H2O, siderite, FeCO3". Iron ore in addition to iron compounds, but also contains silicon, manganese, phosphorus, sulfur and other compounds, collectively referred to as gangueCoke: the heat of combustion provides a heat source for iron smelting; the CO gas produced by incomplete combustion serves as a reducing agent to reduce iron from the oreFlux: Limestone (CaCO3) and fluorite (CaF2). Its function is to combine with the gangue in the iron ore to form molten slag with low melting point, small density and good fluidity, so that it can be separated from the molten iron so as to obtain more pure pig iron liquid
Q:What iron ore does the cement plant use?
Cement is usually made of ordinary portland cement, Portland cement mixed with mixed material and special cement. Portland cement mixing material is added according to the proportion of ordinary portland cement and some other materials processing procedures to achieve special effects, such as slag cement, Portland cement, volcano ash fly ash Portland cement, Portland cement and so on. The raw material of the cement is more active than that of the ordinary Portland cement. Special cement is somewhat different in the material stage and the manufacturing process. For example, the high alumina cement (aluminate cement) is made of bauxite and limestone, which is calcined to produce clinker, which is then pulverized into aluminate cement.
Q:What is the current cost of iron ore production?
The import price of iron ore has risen, but not all steel companies rely on imports, such as large state-owned steel prices,
