Ferro Silicon 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.
Ferro Silicon Application
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: What type of carbide for punching dies? Better. Where can I buy it?
- Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
- Q: Are there any German products called K44 which are imported into cemented carbide materials? I am machining hole, K44 is better than domestic material K30?
- Germany never heard of K44, I know K40 is the international organization for standardization as the equivalent of the national standard YG-10H, the hardness of about 1300HV, used for processing softwood or hardwood and nonferrous metal; K30 is equivalent to the national standard YG-8, the hardness of about 1400HV, suitable for low hardness of grey cast iron, low tensile strength steel and compressed wood.Compared with the two, K40 has higher toughness, but its wear resistance is lower.
- Q: What is called cemented carbide?
- In addition to carbon atoms, a nitrogen atom and void boron atoms can enter the metal lattice, formed interstitial solid solution. With the properties of mesenchymal type carbide. They are similar to electrical and thermal conductivity, high melting point, high hardness, brittleness and is also large.The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is bonded metalIs the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 degrees. In addition, nitrides, borides, silicides of transition metals have similar characteristics, can also act as a hardening in hard alloy the phase hardening phase due to the existence of alloy with high hardness and wear resistance.Bonding metals are generally iron based metals, and cobalt and nickel are commonly usedManufacture of hard alloy, the size of raw powder in 1 ~ 2 microns, and high purity. Raw materials according to the provisions of the proportion of added alcohol or other medium in the wet ball mill in wet grinding, making them fully mixing, crushing, drying, sieving after adding wax or gel forming agent of a class then, after drying and sieving to prepare a mixture. Then, the mixture granulation, pressure type, heated to the melting point of the metal bond (1300 to 1500 DEG C) when hardening phase and bonding metal to form eutectic alloy. After cooling, the hardening phase distribution in grid bonded metal composition in each other closely together, form a firm whole. The hardness of the hard alloy depends on the hardening phase content and grain size, the hardening phase content is higher, more fine grain, hardness is greater. The toughness of cemented carbide by bonding metal bonded gold decision. The higher the content, the greater the flexural strength
- Q: How are hard alloy fittings machined and polished?
- Cutting tools or ceramic cutting tools for cubic boron nitride material, cobalt alloy cutting tools, etc.,Diamond grinding materials for polishing.
- Q: I would like to solder a carbide tool now, what materials do you need to ask for specific methods?
- Oxygen acetylene kit KitA brass electrodeA bottle of brazing fluxAlloy knife and tool holder materialGoggles payableAdjust the pressure, ignition, adjust the flame, heating the workpiece (alloy placed in the blade position), to the temperature with brazing agent solder, welding, slow cold can!
- Q: High end markets for cemented carbides
- In 2007, 16 thousand and 500 tons of cemented carbide produced in our country, 4500 tons were used in cutting tool production, and the quantity was quite similar to that in japan. But the value of the tool is only 800 million U. S. dollars, far less than Japan's 2 billion 500 million U. S. dollars, which fully shows that the overall production level of domestic carbide efficient tool is still quite a gap with foreign countries. Therefore, in the domestic enterprises can not meet the market demand under the premise of the manufacturing industry will have to rely on a large number of imports to solve. Data show that the main foreign market in China's high-end cutter sales growth rate of 30%, has exceeded the average annual growth rate of domestic knives.
- Q: What are the advantages of carbide V-CUT knives and diamond V-CUT knives?
- The process is more complex and difficult to process. The accuracy is difficult to guarantee. The material is hard and brittle at the same time. When it collides, it breaks easily and breaks the teeth. But the abrasion resistance is good; the V-CUT knife produced is very goodThe advantages of carbide V-CUT knives are: high hardness, high strength, high wear resistance, long service life, and remarkable improvement in production efficiency.
- Q: What kind of grinding wheel is the most suitable for carbide tools?. My existing grinder, 2800 rpm, /s wheel diameter, can hold 250mm. Please help answer.
- Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60Another grinder usually holds two pieces. A piece of green silicon carbide, a piece of brown corundum, brown corundum grinding wheel is used for iron, such as the size and hardness of the cutter bar and green silicon carbide as the new knife. You can also choose 46#'s.Luoyang abrasive tools professional sales all kinds of grinding wheel, carbide blade, diamond grinding wheel
- Q: What does American standard cemented carbide grain size C mean?
- In addition to carbon atoms, nitrogen atoms and boron atoms can also enter the voids in the metal lattices to form interstitial solutions. They are similar to those of interstitial carbides, which can conduct electric conduction, heat conduction, high melting point, hardness and brittleness. The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is a bonding metal. Is the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 DEG C. In addition, transition metal nitrides, boride and silicides have similar properties and can also act as hardening phases in cemented carbides. The presence of the hardened phase determines the alloy's extremely high hardness and wear resistance. Bonding metals are generally iron based metals, and cobalt and nickel are commonly used. In the manufacture of cemented carbide, the size of the raw material powder is between 1~2 microns and the purity is very high. Raw materials according to the provisions of the proportion of added alcohol or other medium in the wet ball mill in wet grinding, making them fully mixing, crushing, drying, sieving after adding wax or gel forming agent of a class, and then drying and sieving to prepare a mixture.
- Q: Why carbide fracture?
- Hard alloy is made by casting sintering of tungsten and cobalt, nickel, titanium and tungsten powder, cobalt and nickel matrix, and it is easy to break a bonding metal, quality and technology, process equipment, but also related to the amount of metal content and bonding, in short, hard alloy production is very complex, the quality is strictly, in order to produce good toughness, wear-resistant tungsten is a long-term process of exploration, experiment, a link may not have a good grasp of the products are not qualified.
