Applications

1 Milled Ferro Silicon 15# is a magnetic ferro silicon produced in electric arc furnaces and subsequently milled to size ranges required. In addition, Milled Ferro Silicon contains aluminum and titanium which enhances its resistance to corrosion.

2 Milled Ferro Silicon 15# is used in slurry density applications for heavy media separation and sink-float processes. Powdered Ferro Silicon is an accepted medium for the gravity separation of minerals, aggregates and metals with a specific gravity of approximately 2.0 to 4.0.

3 Milled Ferro Silicon 15# is used extensively in the dense media separation process in both the metal recycling and mining sectors.

RE FeSi For Casting Manufactural

Q:I would like to solder a carbide tool now, what materials do you need to ask for specific methods?: Just give you a guide to carbide cutting tools, and you'll see

Q:How many models are there? 10Because we want to purchase carbide milling cutters, we would like to know the classification methods and the characteristics of various types of carbide at home.Some people say that Zhuzhou is best, Nanchang, Fujian, Longyan in turn. But there are many factories in a region. How can you say which is good and that is not good?Do you have a YL model?: Overall, Zhuzhou cemented carbide works, Shanghai alloy materials factory, Zigong cemented carbide plant, new carbide knives are good. But the single pair of milling cutters is not clear! There is no YL!

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:What is steel bonded carbide? What are its characteristics?: Steel bonded hard alloy is a kind of material between steel and hard alloy, has the following characteristics: good technological properties with processing and heat treatment, under the annealed state, can be used in machining, car equipment and tool milling, planing, milling, drilling and other mechanical processing. Also, forging welding. Compared with hard alloy, low cost, wide application range.

Q:What are the differences between the two grades of carbide, YT15 and YT5?: YT5 is often used for roughing or machining, impact cutting, and YT15 is usually semi finishing and finishing.

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:5 meters long hard alloy bars, where are they sold?: Almost impossible to sell, you can choose to use media, multi section welding, bonding completed.AskMultistage welding? What welding is it?Chasing the answerUsing a steel as the matrix, the copper inserts are used to complete the desired specifications.

Q:Carbon steel valves in Baidu LibraryThe temperature can reach 425 degrees, is not without welding carbide seal, who has no detailed material ah?,: This 425 DEG C is the limit temperature of ASTM A216: -30 DEG C - +425 DEG CBut if the sealing surface of rice now is PTFE, it can be as high as +80 degrees centigrade. If the PTFE material is good, it can reach +150 centigradeTherefore, the body material is carbon steel, only that the valve body of the temperature range of this materialLook at the inside of the valve,For example, cryogenic carbon steel in LCB, ASTM, A325 can reach -46 degrees --+340 degrees centigradeHowever, if the sealing surface of your body is the sealing surface of plain carbon steel, the temperature range of this carbon steel valve is only the temperature range of the ordinary carbon steelIf you say that now is the carbon steel valves used in the sealing surface of the safety valve, you must need welding hard alloy (STL or D series, etc.) should have strong hardness of hard alloy after treatment, impact resistance.Depends on your flow channel medium, if it is high temperature, it is best to use 316, and so onThe use of valves is a combination of considerations

Q:The difference between HSS and carbide knives: High speed steel which is mainly used in the rapid operation of the machine, its good fatigue performance, high temperature performance is better, but the hardness is generally hard alloy steel mainly refers to alloy steel with high hardness, high hardness of the steel is mainly emphasized in a certain range, but may be brittle or will be relatively large, high performance high temperature, poor.

Q:What kinds of carbide cutting tools are used in the 16 and 20 manganese grinding of the lathe?: YW2 super easy to use, not YG, easy to jump knife
