The introduction of the ferro silicon 75%

The introduction of the ferro silicon

Ferrosilicon has been widely applied.in the steel industry, foundry industry and other industrial production.

Ferrosilicon is indispensable deoxidizer in the steel industry., ferrosilicon is used for precipitation deoxidation and diffusion deoxidation in Ju steel. Brick iron also as an alloying agent used in steelmaking. Adding a certain amount silicon to the steel can significantly improve the strength, hardness,elasticity and permeability of steel, reduce the hysteresis loss of transformer steel.

High ferrosilicon or silicon alloys is used for the production of low-carbon reductant in ferroalloy industry. Adding ferrosilicon to cast iron can be inoculant for ductile iron, and can prevent the formation of carbides, and promote the precipitation of graphite and the nodulizing, so as to improve performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry,and coatings for welding electrodes in the electrode manufacturing

The application of the ferro silicon 75%

(1) in the steel industry used as deoxidizer and alloying agents.

(2) in the iron industry used as a nucleating agent and spheroidizing agent. Cast iron is a kind of important modern industrial metal materials, it is much cheaper than steel, easy to melt refining, excellent casting performance and seismic capacity is far better than steel. Especially the nodular cast iron, its mechanical performance at or near the steel mechanical property. Add a certain amount of silicon in cast iron can prevent iron in formation and precipitation of carbides, and promote the graphite spheroidizing, therefore in the nodular iron production, ferrosilicon inoculants is a kind of important separation graphite (help) and spheroidizing agent.

(3) used as a reductant in ferroalloy production. Not only chemical affinity between silicon and oxygen is very big, but also high silicon silicon carbon content is very low. So high silicon ferrosilicon (or siliceous alloy) is a low-carbon ferroalloy ferroalloy industry production more commonly used a reducing agent.

Q:Which is better, cemented carbide, YG8 and YG20?
YG8 and YG20 are two grades of cemented carbide. They are not good or bad. It depends on what occasion you use
Q:I would like to ask, carbide processing, cutting what cutting fluid is better, useful trouble recommended, thank you!
We are interested in many models, and finally found a cutting tool for carbide cutting fluid, MB132 extreme pressure microemulsion, in Dongguan. The cutting effect is satisfactory in the cutting fluid I tried.
Q:What are the contents of cemented carbide production test 20
Fluorescence detection: fluorescence detectorScanning electron microscope: SEM scanning electron microscopeXRD: XRD testElectron microscopy: TEM projection electron microscopyMy school student, brother, I speak not all, you should all do so, detection cost is not expensive, but the equipment to buy it, not tens of millions of nabuxialai, and equipment is not the same.
Q:Japan steel tungsten carbide which is good
Japan steel tungsten carbide recommended Kunshan aloi precision mould Co. Ltd, Japan Istanbul technology research of copper tungsten alloy used for professional sales of Japanese steel tungsten carbide and discharge EDM, silver tungsten alloy, copper alloy; discharge EDM tungsten copper, copper thread electrode; non-standard thread electrode, thread grinding machining
Q:Hello, what's your company? What do you do with carbide? Thank you in advance
Our company is the manufacturer of woodworking knives, made of carbide alloy circular saw blades and forming tools.
Q:Hard alloy bars where the hard alloy blade,
Hello, I'm from Zhuzhou CREE cemented carbide Co., Ltd.We are specializing in the production of various specifications of hard alloy, Zhuzhou cemented carbide, Zhuzhou hard alloy, sand making machine alloy strip, hard alloy ball tooth, carbide blade, hard alloy bars, welding blade, milling cutter, long and thin; manufacturers selling cheaper price; all kinds of hard alloy, Zhuzhou cemented carbide, Zhuzhou hard alloy sand making machine alloy, hard alloy ball tooth, carbide blade, hard alloy bars, welding blade, milling cutter, long and thin, everything, quality assurance; welcome you to come to the consultation, to serve you is our honor.
Q:What are the YT and YG carbide cutting tools for each occasion and why is it necessary to improve the quality of the machined surface?
YT for steel, steel castings, aluminum parts, not shock resistance. YG is used for rough cast iron parts, cast iron parts, shock resistance and high temperature resistance.
Q:How to polish and polish cemented carbide? Five
First of all, is the alloy itself if there are problems, product patterns, mainly to see the pattern is a kind of form, if a cluster or cluster, is generally the product of carburizing, such products also have a feature in 40 times under the anatomical microscope observation, can see the concave point, the because the graphite particles in the grinding conditions, free C from the alloy caused by the desquamation of this kind of products, should not be a problem after carburizing burnback.
Q:Carbide tool number with a suitable speed of 20
The surface quality is good, the blank diameter is 50MM. Can play around eight hundred rpm. When the car is refined, 1200r/min.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron and non-ferrous metals.
Q:Is the hard alloy the same as the cemented carbide?
Dissimilarity!Cemented carbide refers to one or more refractory metal carbides (WC, TiC, etc.) as hard phases, and transition metals (Co, etc.) as bonding phases and multiphase materials prepared by powder metallurgy technology. As carbide tools for cutting tools, the commonly used carbides are WC, TiC, TaC, NbC and so on. The commonly used bonding phases are Co, Ni, Fe and so on. The strength of cemented carbide depends mainly on the content of the binder phase.The ultra-fine Grain Cemented Carbide Kennametal company launched a new brand KC5525, KC5510 uses the high cobalt hard alloy matrix grain refinement, cemented carbide substrate with super grain refinement cobalt content up to 10%, with TiAlNPVD coating with high aluminum content, the tools in intermittent cutting with high edge toughness at the same time, also has a very strong deformation resistance. ISCAR company for solid carbide end mills "AL-TEC" brand series of coating, with ultra-fine Grain Cemented Carbide with high aluminum content, TiAlN (PVD) coating, which in milling high hardness of 60 ~ 62HRC hardened steel, compared with the original IC903 grade, improve tool life 150%. Valenite company for cast iron in high-speed turning VP1595 grades, but also in the ultra-fine grain cemented carbide substrate, using MT-CVD coated with 18 m thick TiCN/Al2O3/TiC coating, the flank is coated with a layer of gray TiC, in order to facilitate and blade rotation observing the wear of cutting edge, the grade in rough machining ductile iron, the processing efficiency than other K05 ~ K10 grade increased by 50%.
