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. Because silicon and oxygen are easily compound 

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. 

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

Q:Who knows what the melting points of hematite and limonite are?
Hematite has primary, there are wild, magnetite hematite after oxidation regeneration after the loss of magnetic, but still retains the crystal shape of magnetite martite, in martite often contain some residual magnetite weathering products. Sometimes also contain some hematite hematite, such as limonite (2Fe2O33H2O).Hematite has semi metallic luster, crystalline hardness is 5.6, earthy hematite is very low hardness, no cleavage, relative density 4.5.3, only weakly magnetic, gangue silicate
Q:Do waste rock iron have any harm to human body?
The pyrite pyrite smelting sulfur harm on environment and governance of the 1. indigenous smelting sulfur harmful, sulfur dioxide gas generated a strong stimulation, cause damage to the eyes and respiratory system, when the concentration reaches 8 * 10-6 to 20 * 10-6, causing coughing and eye discomfort, when the concentration exceeds 5 * 10-4, will endanger life. Damage to the environment is also very serious, in the indigenous smelting sulfur area, the surrounding farmland and forest were destroyed, barren, waste gas pollution serious destruction of the natural ecological balance.
Q:The color and hardness of hematite ore
The chemical composition of hematite is Fe2O3, and crystal is an oxide mineral of six 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 Specularite; 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:Types of iron ore
Hematite hematite is anhydrous iron oxide ore, its chemical formula is Fe2O3, the theoretical iron content is 70%. This kind of ore often forms huge ore deposits in nature, and it is the main ore of industrial production from the burial and mining amount.
Q:What is the current cost of iron ore production?
But on the contrary, some products are subject to customs duties. The living space of small enterprises is gone. The listed steel enterprises are all countries. The small counterparts will not need to buy more foreign iron ore, they will buy more, but not much
Q:What is called lean magnetite?
Ultra poor magnetite refers to magnetic iron (mFe) content is lower than the current standard for selection of iron ore iron ore industry index, industrial grade is 8%, in the current economic technology (including environmental conditions) on the development and utilization of iron bearing rocks. The development of super lean magnetite has the characteristics of high market sensitivity, large profit range, big economic risk, less ore dressing ratio (generally 1: 7~1: 10), large amount of tailings discharge and high environmental pressure.
Q:What does magnetite do to humans?
The Southern Song Dynasty and the "Yan Ji Sheng Fang" (1253 AD) medical book told by a cure ear hearing is not good, this is a big magnet with new cotton beans into the ear, and then with a piece of iron in the mouth, it can improve the listening ear disease. In general, medical records of various diseases are often used in medical books of various dynasties. Famous pharmaceutical Ming Li Shizhen the "Compendium of Materia Medica" on medical record content a rich and summary, the magnet shape, indications of disease, drug preparation method and various application described in great detail, such as the treatment of ear diseases are a fulminant deafness deafness, the elderly kidney closed, deafness, virtual old man loss, eyes faint cataract in children, epilepsy, uterine prolapse, undertake not to close, e., blood, intestinal tumors swallowed needle iron, Ding swollen swollen poison toxic heat, all 10 kinds of diseases, the use of medicine made of a magnet Cizhu pill, Zixuesan Erlongzuoci pills and etc..
Q:Which iron ore is often used for iron making?
Magnetite in the scratches on the porcelain fracture is black, dense and hard tissue, small porosity, reduction is difficult. Magnetite can be seen as a combination of Fe2O3 and FeO, Fe2O369%, FeO31%, the theory of iron content of 72.4%. in the nature of pure magnetite rarely seen, due to the different degree of oxidation, Fe2O3 composition of magnetite the increase of FeO content reduced. Magnetite is magnetic, which is the most prominent feature of magnetite.
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:Where's the biggest iron mine in China?
In terms of provinces and autonomous regions, Liaoning ranks first in proven reserves, followed by Hebei, Sichuan, Shanxi, Anhui, Yunnan and Inner Mongolia. China in iron ore, rich iron ore less ore reserves accounted for 2.53% of the total reserves, found only in Hainan and Hubei and other places of Daye city. From the point of view of iron ore genesis, according to Cheng Yuqi and Zhao Yiming's opinion, the main iron and basic ultrabasic magmatic intrusive magmatic deposit related activities, such as Sichuan Panzhihua iron ore deposit, and the acidic (including partial mafic and alkaline) magmatic metasomatic hydrothermal activities related to iron ore deposits such as Hubei, Daye, Fujian, Inner Mongolia Huanggang, Ma keng;
