Atomised Ferro Silicon 15 is a specialised powder product formed by melting FeSi75 with scrap and casting into a high pressure water jet. Particle size is typically between 212 microns and 20 microns. The principal properties of FeSi15%

are magnetism, corrosion resistance and density.

Atomised Ferro Silicon 15% is mixed in water to create a dense medium and finds uses in the mining and scrap processing industries. Dense medium separation is a gravity separation technique which creates a medium with a specific density.

This medium allows lights to float and heavies to sink, thus permitting separation due to density. The process typically

separates aluminium, magnesium and mixed heavy metals such as copper alloys, thereby increasing overall scrap

metal recycling rates. After sizing, the mixed feed is screened and then sent to a drum containing magnetite media

which removes the lower density waste (rubber, plastic, etc) and light metals such as magnesium alloys.


The heavy concentrated scrap is then directed to a second drum containing FeSi media which separates the aluminium

from other metals. These two media, namely Magnetite and FeSi, create different media densities and can be adjusted,

within certain limits.

Atomised Ferro Silicon 15% is usually supplied in big bags or in steel drums.

Q:General carbide and high-speed steel blade cutting speed? (about the range is OK.)
Carbide cutting tools, cutting speed limit is 100 meters / minute, usually 50-70 meters per minute;High speed steel cutting tool cutting line speed limit is 10 meters / minute, commonly used 5-8 meters / min..
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:Why is carbide cutting tools less standard than high speed steel cutting tools?
Because the hard alloy material rigidity is better, the brittleness is bigger, the toughness is relatively bad, namely is easier than the high speed steel cutting tool to break off, after grinding blunt, the force is more complex. Greater resistance. Do you want your expensive tool to break?.
Q:Carbide blade domestic that tricky point?
Too much, there are at least dozens of domestic do this.
Q:What cemented carbide does 2gr13 use?
2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.
Q:The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason
Hard to turn materials require different speeds and special turning tools. There is a reasonable amount of feed. Ordinary alloy knives are very easy to break
Q:With 80 diameter milling cutter,
This belongs to the category of ductile iron, more difficult to process, because the material is hard particles, it is recommended around S=1200 F=400
Q:How are cemented carbides sintered?
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. Then, when the mixture is granulated and pressed and heated to a point near the bonding metal (1300~1500 DEG C), the eutectic alloy is formed by the hardening and bonding of the metal.
Q:Carbide saw blades, plain and alternating teeth. What do you mean? That good?
The 3. ladder flat tooth is a combination of trapezoidal teeth and peace teeth, and the grinding is more complicated. When sawing, the utility model can reduce the phenomenon of overlaying and cracking, and is suitable for sawing and cutting all kinds of single and double facing artificial boards and fireproof boards. Aluminum saw blade, in order to prevent adhesion, but also more flat teeth with more teeth.4. ladder tooth often used for cutting saw blade trough, in artificial plate sawing double veneer, adjust the thickness of the bottom surface of the groove saw complete grooving, the main saw complete plate sawing, cutting edge to prevent the occurrence of collapse phenomenon.In summary, sawing wood, particleboard, MDF or tooth, can be sharp wood fiber cut, cut smooth; in order to keep the grooving bottom flat, with flat tooth or flat composite tooth; sawing plywood, fireproof board generally choose ladder flat teeth, is expected to open the computer the sawing sawing rate, diameter and thickness of the alloy blades are relatively large, about 350-450mm in diameter, 4.0-4.8mm in thickness, most of the ladder flat teeth, in order to reduce the edge collapse, saw.
Q:What does American standard cemented carbide grain size C mean?
Then, when the mixture is granulated and pressed and heated to a point near the bonding metal (1300~1500 DEG C), the eutectic alloy is formed by the hardening and bonding of the metal. After cooling, the hardened phases are distributed in a grid of bonded metals that are closely related to each other and form a solid whole. The hardness of cemented carbide depends on the content of the hardened phase and grain size. The higher the content of the hardened phase and the finer the grain, the greater the hardness. The toughness of cemented carbide is determined by bonding metal. The higher the bonding metal content is, the greater the bending strength is. The effect of grain size on the mechanical properties of metals has a curve diagram: the strength of both ends is large and the middle is low. Explain: the mechanical properties of single crystals are very good. The finer the grain, the better the mechanical properties, but the mechanical properties of the single crystal with infinite size are much better than the grain's infinitesimal! A lot of grain size control method, the main principle of two: 1, increase the metal crystallization undercooling of 2, increase the crystal nucleus specific methods: electromagnetic stirring, adding grain refiner (such as Aluminum Alloy plus Al-Ti-C master alloy as grain refiner), lower solidification temperature, and fine grain of alloy elements and so on many.
