                  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:Fuzhou where to buy steel tungsten carbide
You can learn about the same carbide shipped to Fuzhou on the Internet, Zhuzhou soon.
Q:Is there any pollution in the production of cemented carbide?
The main pollutants in the production of cemented carbide are dust, waste residue and waste water, and the biggest influence on the environment is soot. According to regulations, waste gas can be divided into two categories: particulate matter, exhaust gas and gaseous pollutants. The exhaust gas of ferroalloy plant comes from ore smelting furnace, refining electric furnace, roasting rotary kiln, multi layer mechanical baking furnace and aluminum metal smelting furnace. Ferroalloy plant exhaust emissions, dust concentration is high, 90% of exhaust gas is silicon dioxide, but also contains chlorine, nitrogen oxides, carbon monoxide, sulfur dioxide and so on. Waste residue and waste water are the most serious pollution of chromium compounds, and there are also pollution of nickel compounds.The State Economic and Trade Commission, the State Environmental Protection Administration and other departments also jointly issued "on accelerating the restructuring of China's ferroalloy industry views" (in the economic and trade industry [1999]633), from 1999 to 2005, to stop the new types of ferroalloy electric furnace (kiln) and blast furnace.
Q:What are the differences in performance between cemented carbide cutting tools and PCD cutters (polycrystalline diamond)?
The former is cut by ordinary metal materials, the latter is used for cutting superhard materials
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:What are the types, codes, and range of application of cemented carbides?
I am also engaged in carbide industry, different grades (there are ISO brand, there are some domestic brands, and some even use the manufacturer's own brand) on behalf of the composition and use of the barrier.. Because of the wide variety of brand names, the average person will only involve one or several specific industries, and there is no need to know all the code names and their detailed performance... Therefore, we usually produce or recommend the brand (code name) according to the performance and use of the customer..Customers are generally in order before provide you with detailed performance parameters, although not in the factory name brand in different, but according to the performance parameters of the still commonly found in different plant in the corresponding or similar grades, but some brands of blade complex, and complex composition, tell you some properties can not be done with the original brand as like as two peas.. In the blade field, there is still a big gap between China and foreign countriesAlso, due to the development of hard alloy, grade ISO has lost his original meaning of..K20, K30, K40, K05.. And so on, people don't seem to know what they want, if my client told me that these ISO grades, I basically have to provide him with detailed performance parameters..Friends, you are in that industry, our company mainly engaged in geological and mining products (ball gear, drill chip, pick, engineering, knife, shovel snow tooth.Etc)
Q:Can hard alloy be welded with silver electrode?
Hard alloy can use silver electrode welding, some more liquid silver wire than general tin brass or iron brass, the cost is too high, the strength level than the ordinary copper electrode should be higher, personal suggestions for the selection of copper base up instead of silver electrode, such as the WEWELDING 46 electrode (referred to as Odin Wei 46 If the strength of electrodes), the structure is higher than silver, if it is to achieve the high permeability, it is still the ideal to silver, only from the strength level, is not WEWELDING 46 copper based electrode.
Q:The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason
The cutter model is wrong, the milling can not move the material, the resistance is big, then the knife breaks. Use 75 degrees to make the plane
Q:What kind of industry can use carbide?
Blade material used in mechanical processing
Q:What does American standard cemented carbide grain size C mean?
In addition to carbon atoms, nitrogen atoms and boron atoms can also enter the voids in the metal lattices to form interstitial solutions. They are similar to those of interstitial carbides, which can conduct electric conduction, heat conduction, high melting point, hardness and brittleness. The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is a bonding metal. Is 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 DEG C. In addition, transition metal nitrides, boride and silicides have similar properties and can also act as hardening phases in cemented carbides. The presence of the hardened phase determines the alloy's extremely high hardness and wear resistance. Bonding metals are generally iron based metals, and cobalt and nickel are commonly used. In the manufacture of cemented carbide, the size of the raw material powder is between 1~2 microns and the purity is very high. 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.
Q:Carbide according to the structure of the words, what can be divided into?
The microstructure of the hard alloy, and can be divided into structural and non uniform structure, which contains many kinds of non uniform structure, such as the gradient structure of hard alloy and hard alloy honeycomb structure, the special non hard alloy uniform structure is applicable in industrial production should be stronger than ordinary hard alloy.
