                  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 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:What material is that ultrafine cemented carbide?
You mean the ultra-fine grain cemented carbide, generally we have 0.6 alloy grain size is fine, which belongs to the tungsten carbide base hard alloy, ordinary tungsten carbide base hard alloy strength and hardness are higher than the same cobalt content. The process is mainly mixing, wetting, drying, forming, sintering, finishing, such as sand blasting, CVD/PVD coating, heat treatment, etc.
Q:What are the carbide cutting tool brands? 10
The high-end products are M.A.FORD (Mei Fu) Sandvik, Kenna, guhring, Leitz, ISCA, WalterMost of the middle end is Korean and JapaneseLow-end is made in Taiwan
Q:Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?
The main component of the tungsten steel milling cutter in cemented carbide is tungsten carbide, tungsten steel on steel hardness and heat resistance are significantly improved, but the toughness decreased sharply.
Q:Buy whole cold carbide drills
Xi'an Jie Electrical Machinery Co., Ltd. internal cooling alloy drill, factory direct sales
Q:What kind of clamp blade should be used for hard alloy?
Hard alloy tools are used for turning cemented carbides. Now the general superhard materials are PCD (polycrystalline diamond) and PCBN (poly cubic boron nitride)However, because carbide contains more carbon elements, PCD is easy to produce chemical dissolution (carbon affinity) during processing, so the PCBN blade should be considered.
Q:Carbide coated drill bit
3. the wear of drill bit belt has the most serious influence on drill bit life.4. so, when using the drill, pay attention to it:(1) the drill should be kept as small as possible at the top of the drill bit.(2) the spindle of machine tool has enough rigidity and precision.(3) the drill shall be replaced and sharpened when used.
Q:What about cemented carbide produced in Zhuzhou? What brand is good?
Is good at home, as for the brand well of course is diamond, refined into a brand is also good, there are fine into hard alloy sales company, previously entered a large red facade, product is very much, the Diamond Road No. 24-5, hope to help to you.
Q:Detailed comparison of cemented carbide with diamond properties
Hard alloy is a metal, usually refers to the number of tungsten carbide hard alloy components, there are many brands, such as YT YG series, this is found, it is mainly used as the traditional machining industry, a cutter head, tools, etc., our common lathe tool tip is above the hard alloy. The largest hard alloy base China in Hunan Zhuzhou tungsten group, a few years ago by Minmetals acquisition. Diamond is a non-metal is allotrope of carbon, he is by far the highest hardness of substances found in nature. Synthetic diamond, also known as industrial diamond, has developed rapidly in China in the past ten years. Its total output has accounted for more than 90% of the total amount of the world. With diamond related diamond tools, mainly used in the field of drilling, cutting, grinding, polishing, grinding, geological, stone, construction, industrial processing, precision instruments, aerospace, electronics, also known as super abrasive, and he (ordinary abrasive corundum and silicon carbide) called industrial teeth "plays a vital role in the economic development of Chinese.
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
