Product Description:

 

Description 

 Ferro Silicon is one  of ferroalloy which is made from  ferrum and silicon. Ferro Silicon uses coke, quartz 

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

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

Features 

1. 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. 

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

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

Q:What is the main component of magnetite?
Magnetite Magnetite is an oxide mineral, magnetite ore. Equiaxed system. The crystal has eight sides and twelve faces. The surface of the crystal has stripes. Most of them are granules and lumps. Iron black, or a Dark Indigo color. Streak black, semi metallic luster. Opacity. No cleavage. Uneven fracture. Hardness 5.5 ~ 6.5. The density of 5.16 ~ 5.18g/cm fand. Strongly magnetic. Sexual fragility. Odorless, tasteless. Often occurring in igneous rocks and metamorphic rocks. Beach sand often exist. Distribution of Shandong, Hebei, Henan, Liaoning, Heilongjiang, Inner Mongolia, Hubei, Yunnan, Anhui, Guangdong, Sichuan, Shanxi, Jiangsu, and Hong kong.
Q:How did the sedimentary pyrite form?
Pyrite is one of the most widely distributed of sulfide minerals in the earth, is the main component of two iron sulfide (FeS2), pure pyrite containing 46.67% iron and 53.33% sulfur industry called pyrite. Often crystalline or massive aggregates of cubes, five angles, twelve faces, found in a variety of ore and rock origin. The pyrite in the coal seam tends to be a nodule. Because of its pale brass color and bright metallic luster, it is often mistaken for gold, so it is also called "fool's gold"".
Q:Rocky heroes pass through primary iron ore. Which one can come out?
1, in the world of Lodge heroes, mines and other materials are not the same as traditional online games.2, lodge hero pass primary cloth, is monster fall. And the lodge hero, a primary iron ore, needed a bomb to blow it up.
Q:Why calcination furnace is used in the production of sulfuric acid from calcined pyrite?
Controlling the particle size of the furnace is stable and standard. It is also a prerequisite to ensure long period operation of the fluidized bed furnace. In particular, the burning of tailings of the furnace, a large number of large quantities of raw materials into the furnace, will soon lead to cold ash deposition in the furnace, the bad treatment will be cold, gray scarring. Therefore, in the screening process of raw materials, once the sieve is found damaged, it must be repaired or replaced immediately. Therefore, the sieve is best left in place. In the production process, the bottom temperature suddenly dropped to normal temperature, boiling layer upper temperature normal or decreased (no temperature rise and the outlet of the boiler or the first stage purification equipment before the temperature rise phenomenon), observe the direction of the furnace boiling condition is not good, the dark color, through analysis, troubleshooting and scarring the furnace cooling water tank leak, cold ash processed by the furnace out.
Q:Hematite and magnetite iron, which is more suitable for iron smelting, why?
In nature, there are two known variants of Fe2O3, namely, alpha -Fe2O3 and gamma -Fe2O3. The former is stable under natural conditions and is called hematite. The latter is inferior to alpha -Fe2O3 in natural conditions and metastable state. It is called hematite.
Q:WOW iron ore where more?
125 go to Alahi heights, secondary blood ore can be dug the hole hammer town on the right, although not what this ore, but red skill is good, otherwise this stage is hard to improve the skills.Then the advanced, you can still continue to dig here, blood mineral can improve skills, but also can be dug Mithril ore cave.
Q:Is pyrite the pyrite?
Pyrite because of its shallow brass color and bright metallic luster, is often mistaken for gold, so it is also called "fool's gold". Components usually containing cobalt, nickel and selenium, with NaCl type crystal structure. The same composition and is orthogonal (orthorhombic) system called the white iron composition also often. There are traces of cobalt, nickel, copper, gold, selenium and other elements, high content and comprehensive utilization in the process of extracting sulfur.
Q:Does iron ore have radiation on the human body?
Iron meteorite radiation value is generally 0.10 micro West, the air radiation value is generally 0.15 micro Fu fu. The iron ore is uncertain, but definitely higher than the two. Human tolerance limit value of 2.5 micro, but above this value, radiometer will alarm.
Q:Where is China's largest iron ore resource?
The largest single mine has been developed, which is the Hebei iron and steel company's iron ore mine. The undeveloped iron ore mine is Benxi.
Q:Can metal detectors detect iron ore, such as gold ore
In the military, the metal detector can be used to detect metal mines; in the field of security, can detect carry or hidden weapons and tools; in archaeology, can detect buried metal objects of the tomb, and find the treasures of gold and silver jewelry in the tomb or other metal products; in engineering, can be used to detect metal buried underground for example, pipelines and pipelines; in mineral exploration, and found that the particles can be used to detect natural gold; industry, can be used for online monitoring, such as removing cotton, coal, metal and other debris in food. The metal detector can be used as teenagers to carry out national defense education and science activities is also interesting entertainment appliances, toys, especially in recent years, Europe and the United States have a person of interest will be a large scale metal detector, metal detection activities become part of the evolution of outdoor sports
