Product Description:


Ferro silicon is widely used in the steel making,iron casting ,low-carbon ferroalloy producing:

1 In the steel making field,Ferro silicon is used as deoxidizer and alloying agent to precipit and diffusedeoxidation.Adding a certain amount silicon of fe-si to the steel can obviously improve the strength ,hardness ,elasticity and permeability of steel.

2 In the iron casting,it is used as ball mile agent and alloying agent especially in the nodular iron casting, Adding ferrosilicon to cast iron ,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing.then the mechanical capacity can be the same of steel's.

3 High-silicon ferrosilicon can be used for the production of the low-carbon reductant in ferro alloy industry.

4 In addition ,ferro silicon powder can be used as a suspended phase in the mineral processing industry and coatings for welding electrodes in the electrode manufactruing.


Used as deoxidants and desulfurizing agents, and could purity the molten steel, etc. The size includes:0-3mm, 3-25mm,10-50mm, etc.

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:Carbide tool number with a suitable speed of 20
The hungry! For the 450--700 rpm, the most appropriate, because once you and I work almost, I use the 6140 machine, crude car to 450 rpm to 700 RPM fine car is good. If the surface quality is good, the blank is not much, you can use 450 turn into a knife, but the knife grinding......
Q:What material is that ultrafine cemented carbide?
Comparison of high-end materials, suitable for high - quality products, are generally fine particles of products. Its hardness and strength are superior. So the price is relatively high
Q:What does American standard cemented carbide grain size C mean?
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. Metal carbides, especially B, B, IV V VI B metal carbide melting point is above 3273K, the TAC hafnium carbide, respectively 4160K and 4150K, is the highest point currently know material. Most of the carbide hardness large, their microhardness is higher than 1800kg mm2 (micro hardness is hardness says one way for hard alloy and hard compound, microhardness 1800kg mm2 is equivalent to a diamond a Mohs hardness of 9). Many carbides are difficult to break down at high temperatures, and their antioxidant power is stronger than their constituent metals. Titanium carbide has the best thermal stability in all carbides, and is a very important metal type carbide. However, in an oxidizing atmosphere, all carbides are readily oxidized at high temperatures, which can be said to be a major weakness of carbides.
Q:Carbide saw blade 30t and 40t what is the difference?
Because of the small friction, the 40 teeth will save effort and the noise will be small, but the more than 60 saw blades will be cut more smoothly.
Q:What materials are ZK20 cemented carbides processed?
ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic
Q:What are the fields of nano WC Cemented Carbides applied?
(4) medical application. The drill is a fine medical instrument, the incision must be sharp, but also has good abrasion resistance and toughness, application of ultrafine grain WC hard alloy with high strength, high toughness and wear resistance in this field widely. (5) other applications. Nanocrystalline WC hard alloy because of its fine grain, as the cutting tool can grind the cutting edge radius and high precision, sharp nose arc; because of its high strength can be used for making fine tool rake angle, feed rate and small amount of snacks knife, such as small diameter cutter, reamer etc. because of its high elasticity; modulus and friction wear properties, can be used for the production of high precision mould, punch etc.; also can be used for the production of high wear resistance, erosion resistance, such as high-pressure nozzle, valve, high-pressure gun, glass cutter, cutter and textile tape, tape cutter etc.. In addition, scientists are developing circular tools, rock drilling tools and nano WC-Co based reinforced composites. Therefore, the development of nano WC cemented carbide and the search for wider applications become the focus of development, and the key technology of preparation is the preparation of nano powder and the subsequent sintering process. Particle size is to improve the performance of WC-Co hard alloy (strength, hardness and wear resistance of the Jun effective way, therefore the development of nano cemented carbide is the development focus of the next phase of the study, it will greatly broaden the application field of WC-Co hard alloy, and thus lead to a variety of precision instruments, mold, tool and electronic communication technology rapid development.
Q:Are there any German products called K44 which are imported into cemented carbide materials?
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 kind of industry can use carbide?
Blade material used in mechanical processing
Q:What is the tungsten alloy blade, what is the difference with the hard alloy blade? What is it for?
Tungsten alloy blade is a kind of hard alloy, metal processing used in the workpiece.You search for Zhuzhou cemented carbide first station can help you to find out more information
