Product Description:

 

Description 

 Ferro Silicon is one kind of ferroalloy which composes ferrum and silicon. Ferro Silicon uses coke, quartz 

(or silica) as raw materials and it  is made by electric furnace. Owing to that silicon and oxygen are easily compound 

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

Features 

 1. Fesi 65% 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. Ferro alloy can be used as a reductant in ferroalloy production and chemical industry.

Q:What are the factors that affect the rate of reduction of iron ore?
There are many factors that affect the reducibility of iron ore, such as grain size, porosity, mineral composition and structure, gangue composition and so on. We should make a comprehensive consideration according to the actual production situation.
Q:How many kinds of iron ore are there? What is the color lattice of an ore?
Siderite (Siderite) is an ore containing iron carbonate, the main component is FeCO3, showing bluish gray, the proportion is about 3.8. Most of this ore contains a considerable amount of calcium salt and magnesium salt. Due to high temperature carbonate on about 800 to 900 DEG C will absorb a lot of heat and emit carbon dioxide, so we put most of this kind of ore after roasting with blast furnace.
Q:What is pyrite used for?
Pyrite is an important chemical mineral raw material, mainly used in the manufacture of sulfuric acid. Some are used in chemical raw materials to produce sulfur and various sulfur-containing compounds. It has important uses in rubber, paper making, textiles, food, matches and other industries and agriculture. Especially in industry for the manufacture of various military products, smoke agents, etc.. Sulfuric acid is prepared from pyrite, whose slag can be used for iron making and steelmaking. If the slag has a high sulfur content and the iron content is not high, it can be used as a subsidiary material of cement mixture. In addition, pyrite is often associated with copper, lead, zinc, molybdenum and other sulfide deposits, and contains gold, cobalt, molybdenum and rare elements selenium, etc., can be comprehensively recovered and utilized.
Q:What is the purpose of pyrite ore crushing when pyrite produces sulphuric acid?
Light yellow brass surface, often with yellow brown tarnish. Green black brown or black streak. Having a strong metallic luster. Opacity. No cleavage, fracture shape, hardness 6~6.5, relative density 4.9~5.2. Detection capability.Pyrite is a semiconducting mineral. Because of the substitution of unequal impurity components such as Co3 and Ni3 instead of Fe2 or [As]3 and [AsS]3 instead of [S2]2-, the electron heart (n type) or hole core (P type) is produced and has conductivity. Under the action of heat, the trapped electrons are easy to flow and directional, forming electron flow, generating thermoelectric EMFs, and having thermoelectric properties.
Q:Can metal detectors detect iron ore, such as gold ore
Detectable.But pay attention to, for ore, iron ore detection sensitivity is much higher than gold, iron less than 1% can be detected, gold needs at least 5 grams / ton or more before you can detect.
Q:What are the major differences between ilmenite and ilmenite?
Used as a purifying agent for iron and steel. High carbon titanium iron containing 17% titanium, 7% carbon and residual iron is used as a ladle additive for purifying steel. Low carbon titanium ferroalloy containing titanium 20% ~ 25%, carbon 0.10%, silicon 4%, lead 3.5%, more than iron, as a reducing agent, are used ilmenite smelting in the electric furnace. Its price per ton is more than 10000 yuan.
Q:What are the common types of iron ore?
It depends on how it is divided. According to the chemical structure, there are hematite, limonite and magnetite. In accordance with the division of production, there are mainstream mines, non mainstream mines.
Q:What is the current cost of iron ore production?
Don't worry. Anshan Mining several years ago to cut down a lot of waste of resources. Although the state import branch, but there are still hand resources. I am also mills, the national demand for imported iron ore large, pollution, requires all close extra small businesses. Don't have to add.2007 export tariffs in May, exports of steel products is to enjoy the tax rebate
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:Magnetite, hematite, and pyrite. Which one is not suitable for iron making? Why?
The weathering products belonging to the iron minerals (Fe2O3 - nH2O), impure, content change of water is also great. Usually the yellow to brown streak of brown, black, semi metallic luster, massive, bell emulsion, grape like, porous or powder, often showed nodular or pyrite the crystal form of illusion. The hardness varies with mineral forms, no magnetism. Limonite is under oxidizing conditions extremely secondary general, in the oxidation zone of sulfide deposits often constitute the "red cap", can be used as a sign of prospecting.
