Product Description:

 

Description 

 Ferro Silicon is a kind 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. Owing to that silicon and oxygen are easily compounded 

into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking. 

Features 

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

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.

Q:Why screw steel, wire rod is Chinese unique, no outside?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:The color and hardness of hematite ore
Chalcopyrite is a kind of copper iron sulfide mineral. Brass yellow, often have blue, purple brown porphyritic tarnish surface. Green black streak. Metallic luster; opaque. No cleavage. Conductive [2]. Hardness 3~4. Sexual fragility. Relative density 4.1~4.3.
Q:Is iron ore a renewable resource?
Renewable resources refer to resources that can be reused or can be regenerated or reused in a short period of time.
Q:Types of iron ore
Magnetite mainly contains iron minerals, magnetite, and its chemical formula is Fe3O4, in which FeO=31%, Fe2O3=69%, the theoretical iron content of 72.4%. This ore sometimes contains TiO2 and V2O5 composite ore, called titanium magnetite or vanadium titanium magnetite. Magnetite has strong magnetism, crystals often become eight faces, and a few are rhombic twelve bodies. Often aggregate into dense clumps, color streak iron black, semi metallic luster, relative density of 4.9 to 5.2, the hardness of 5.5 ~ 6, no cleavage, gangue is mainly quartz and silicate. Poor reducibility, generally containing harmful impurities, sulfur and phosphorus higher.
Q:What is the standard ore in iron ore?
Coarse powder, fine powder, fine powder, coarse powder basically in 0-10 mm, but 10 mm or more generally not more than 10%, 0.15 millimeters below, maximum not more than 35%.
Q:How many kinds of iron ore are there? What is the color lattice of an ore?
(Limonite) this is limonite containing iron ore. It is goethite (Goethite) and HFeO2 (LepidoCRocite) FeO iron ore (OH) are two kinds of different structure of ore, some of the main ingredients in its chemical formula mFe2O3.nH2O, showing brown or brown, containing about 62% Fe, O 27%, H2O 11%, the proportion is about 3.6 ~ 4, mostly with other iron ore.
Q:What are the environmental protection elements in iron ore?
There are many kinds of iron minerals. More than 300 kinds of iron minerals and iron minerals have been found, of which more than 170 species are common. But under the current technical conditions, the main industrial value is magnetite, hematite, magnetite, ilmenite, limonite and siderite.
Q:The difference of iron ore in white iron ore
Both pyrite and pyrite belong to sulfide minerals and have the same chemical composition. The two belong to the homogeneous two image complex, but the crystal structure is different (pyrite, equiaxed crystal, white iron ore, orthorhombic system). The white color is white and iron tin bronze yellow brass with pyrite is not the same.
Q:How many operations are required from iron ore to steel?
The main products are pig iron, the by-products are slag and furnace gas (see the process and principle of smelting)pig ironSteel pig iron: the mass fraction of silicon is low (wSi<1.25%), the fracture is silvery white, mainly used in steel makingCast iron: high mass fraction of silicon (wSi>1.25%~3.2%), the fracture was black, used in cast materials
Q:Which iron ore is often used for iron making?
Industrial iron ore with the iron content accounted for more than 85% of the total iron containing iron minerals named. Iron minerals are divided into iron oxide (Fe2O3, Fe3O4), iron oxide (Fe2O3.nH2O) aqueous and iron carbonate (FeCO3). The use of blast furnace iron ore is divided into hematite (red Fe2O3, magnetite ore) (black ore) Fe3O4, Fe2O3nH2O limonite and siderite FeCO3.
