Ferro silicon 65 manufacturing process
Raw materials to produce fesi 65: coke, iron ore, silica stone.
Requirement to raw materials in ferro silicon 65 manufacturing process: Silica stone SiO2 purity above 97.5%. No sand, dust or other impurities on the surface.
Size ranges between 80-140mm.
Coke with fixed carbon no less than 82%, size 8-18mm, moisture below 16%, volatile matter below 8%, ash content below 8%.
The main chemical equation of ferrosilicon 65% manufacturing process is SiO2 + C = Si + CO.
The whole reaction procedure includes four part:
1. Disproportionated reaction of SiO.
2. Form of Silicon Carbide.
3. Chemical decomposition of silicon carbide, formula SiO2 (L) + 2SiC (S) = 3Si (L) + 2CO (g).
4. Liquid CO2 react with SiC and to form Silicon, SiO2 gas and CO gas, formula 3SiO2 (L) + 2SiC (S) = Si (L) + 2CO (g) + 4SiO (g).
The main facility for fesi65 manufacturing process is electric-arc furnace.
The Si content should be adjusted by raw material adding amount. After the conventional manufacturing process is completed, a process is often required. That is refining. Used to remove aluminum, calcium, carbon and other harmful elements.
Ferrosilicon 65% uses
What is the use of ferro silicon? Ferrosilicon is an iron-silicon alloy made from coke, steel chips, quartz (or silica) as raw materials and smelted in an electric furnace. Since silicon and oxygen are easily synthesized into silicon dioxide. Therefore, ferrosilicon is often used as a deoxidizer when making steel.
We mentioned earlier that ferro silicon 65% has three shapes. Many times different ferrosilicon sizes are used in different places.
- Ferrosilicon 65% lumps are easy to use as deoxidizing agent for steel factory.
- Ferro silicon 65 grains are easy to be used as ferrosilicon inoculant.
- Ferrosilicon powder can be used as flotation agent for various kinds of minerals. And atomized fesi powder are used as electrowelding materials.
Ferrosilicon 65% prices
The price of ferrosilicon 65 is generally around 600-900 USD / ton. When choosing ferrosilicon, we must pay attention to the quality. After all, different prices are certainly different. The Wanhua factory provides high-quality fesi 65 at an affordable price. If necessary, please contact us.
As far as the Chinese market is concerned, the ferrosilicon market remains stable. Manufacturers' inventory is relatively small. Spot price performance was firm.
The tender for steel mills was basically completed in January. Some steel mills will postpone bidding until early February. The operating rate of ferrosilicon before the Spring Festival was relatively stable. Downstream demand shrinks.
On the whole, the market demand for ferrosilicon before the holiday was basically flat. Only some traders dominated sporadic transactions. The short-term ferrosilicon market stabilized and weakened slightly.
