FERRO SILICON

Ferro Silicon is a ferroalloy an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides. Its melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1% to 2% of calcium and aluminium.

Application: Ferro Silicon is usually used in steel industry as a deoxidizing material and it is also used as a bud or spraut in the Moulding industry. It also has major applications as deoxidizing material in steel manufacturing and alloy manufacturing industries, in the production of cast iron and steel, making improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel.

Q: What is the resistivity of the yg13 cemented carbide?: Four, YG13 tungsten steel product featuresYG13 ultrafine particles and by using tungsten alloy in low pressure sintering, uniform grain distribution, good compactness, no pore free porosity and uniform microstructure and excellent wear resistance, 90.5HRA hardness, flexural strength up to 4000MPa and have high wear resistance, comparable to the quality of imported tungsten steel material, some performance parameters are better than similar imported tungsten steel material.

Q: What is the specific gravity of cemented carbide?: Similar to mercury. Tungsten cobalt carbide 14.4~15.3 density, tungsten, cobalt, titanium carbide 9.7~13.2 density, can float in the mercury is a steel knife, sink into the mercury is a cast iron knife

Q: HSS clip can clamp the hard alloy saw it: The cutter head is mounted on the cutter body and the grinding cutter is called an internal grinding type; the cutter head is individually worn on the fixture and is called external grinding type.Indexable(indexable tools): this kind of structure has been widely used in face milling cutters, end mills and three edged cutters.Product classificationTooth milling cutterA narrow blade is sharpened on the flank to form the back angle, and the cutting angle is reasonable, and the service life is higher. Sharp cutter tooth back straight, curve and line 3 forms.

Q: Material properties of Cemented Carbides: Hard alloy with high hardness of refractory metal carbides (WC, TiC) micron powder as the main ingredient, with cobalt or nickel (Co) (Ni), molybdenum (Mo) as the binder, powder metallurgy products in vacuum furnace or hydrogen reduction sintering furnace. IV, B, V, B, VI, B group of metal carbides, nitrides, boride, etc., because of hardness and melting point is particularly high, collectively referred to as cemented carbide. The structure, characteristics and application of hard gold content are described with carbide as the key point. IV, B, V, B, VI, B group metals and carbon formed in the metal type carbide, because the carbon atom radius is small, can be filled in the gaps of the metal lattice, and retain the original lattice form of metal, forming interstitial solid solution. Under appropriate conditions, such solid solution can continue to dissolve its constituent elements until it reaches saturation. Therefore, their composition can change in a certain range (such as the composition of titanium carbide in TiC0.5 ~ TiC changes), chemical formula does not conform to the rules of valence. When the dissolved carbon content exceeds a certain limit (such as titanium carbide in Ti: C=1: 1), the lattice type will be changed, the original metal lattice metal lattice into another form, then the interstitial solid solution called interstitial compounds.

Q: What are the fields of nano WC Cemented Carbides applied?: (2) electronic industry. The development trend of electronic products is miniaturization, integration and precision. The integrated circuit board is made of epoxy resin, glass fiber or glass fiber reinforced plastic. This requires micro drill has high hardness and wear resistance; while the drill diameter is very small (generally 0.2 ~ 0.3mm, and 0.05mm), easy to break, also called bit has high strength and toughness, and need to correct drilling hole position accuracy, and the drill bit has high stiffness (elastic modulus). These conflicting requirements. The common hard alloy and fine grain carbide drills are difficult to meet these requirements, only the use of nano grain carbide grain size of less than 0.5 m. And as the dot printing needle, its diameter is only 0.2-0.35mm; multi frame processing integrated circuit lead by the progressive die, punch thickness less than 0.2mm, the error is only 0.002mm; in addition to the printed circuit board with wire cutting head disc cutter, and the precision of the small die, all require the use of Nanocrystalline WC cemented carbide in order to achieve its function to produce alloy.

Q: How are cemented carbides separated from the cutting tools?: Tools are usually brazed by high-frequency induction:The blade part on the induction coil, through high frequency alternating current induction electromagnetic field, the induced electromotive force generated in the workpiece surface coupling, forming eddy current on the metal surface by eddy current heat generated in the metal surface, the welding parts usually coated with solder powder, welding can be reached until the melting temperature of workpiece. Take off the blade, too.

Q: The difference between HSS and carbide knives: High speed steel which is mainly used in the rapid operation of the machine, its good fatigue performance, high temperature performance is better, but the hardness is generally hard alloy steel mainly refers to alloy steel with high hardness, high hardness of the steel is mainly emphasized in a certain range, but may be brittle or will be relatively large, high performance high temperature, poor.

Q: What blade does the high carbide material use?: CBN diamond tools, the price is relatively high, high hardness with this basic file, but not the car more than 55 degrees of hardening, if necessary diamond tools contact me. Domestic imports.

Q: Printing requirements for cemented carbide: Because of its superior properties such as high strength, hardness, excellent wear resistance and oxidation resistance, carbide is widely used in mechanical processing, petroleum mining, mold forming and structural wear-resistant parts and other fields. In the production of cemented carbide, sintering is the most important process. Even if the compacts are the same, different sintering processes have different effects on the properties of the sintered products. For a long time, many researchers have gradually formed a variety of sintering methods in actual production, including vacuum sintering, hot isostatic pressing sintering, vacuum follow-up hot isostatic pressing, sintering, hot isostatic pressing, etc..

Q: What are hard alloys? Which ones are they? How often are they chosen?: It is based on one or several carbides (TiC and WC) as the hardening phase, with carbon steel or alloy steel (such as high-speed steel, chrome molybdenum steel) powder as binder, powder metallurgy materials through proportioning, mixing, pressing and sintering. After annealing, it can be machined. After quenching and tempering, it has the same hardness and high wear resistance as the hard alloy. It can also be forged and welded, and has the characteristics of heat resistance, corrosion resistance and oxidation resistance. The utility model is suitable for manufacturing various tools with complicated shapes, such as twist drills, milling cutters, etc., and can also manufacture moulds and wear-resistant parts which work at higher temperature.
