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: The difference between carbide knife and white steel knife: 5, the scope of application is not the same: the general tool materials used carbide, complex difficult to shape, or require very sharp, high toughness and other field applicable high-speed steel

Q: Does the hard alloy belong to the composite material?: It's a composite material made up of dock, titanium and cobalt.

Q: The existing 60*60 standard cast iron plate, above 3 hard alloy welding specifications, probably in the 30*30, in which the appropriate welding method, know the friends willing to enlighten ah, thanks in advance.Some friends have said the binder is a copper brazing, the basic can be settled. As far as I know, many methods such as welding, high frequency welding, oxygen welding, I want to find a kind of welding method. The key is to understand the trouble with us, surface and surface welding: Light of copper is not enough, but also a deoxidizing agent, is the most commonly used colophong powder. In addition, there must be a certain level of operation, because I have seen a lot of welding ordinary turning tools, in the work of the alloy head always fall.

Q: Carbide according to the structure of the words, what can be divided into?: Cemented carbides are classified into coarse particles, cemented carbides, medium grained cemented carbides, fine grain cemented carbides, fine grain cemented carbides, ultrafine particles cemented carbide, nano particle cemented carbide. Specific, you can refer to Zhuzhou Jing Jing official website

Q: The use of cemented carbides YG and YT: First, the more common processing carbide used in three categories,:1, YG--- tungsten cobalt alloy products, to YG6, generally suitable for processing iron, non-ferrous metals and their alloys and non-metallic materials continuous cutting of rough cars, intermittent cutting of the semi fine cars and fine cars.2, YT--- tungsten cobalt titanium alloy products, for YT5, for carbon steel and alloy steel rough section, intermittent cutting in the rough car, rough plane, half fine plane, non continuous surface roughing milling and drilling.3, YW---- tungsten, cobalt, titanium, tantalum alloy products.

Q: Compare the advantages and disadvantages of high speed steel and cemented carbide: Must be in a hardened state, in high speed steel iron, chromium, tungsten and carbon forming hard carbide can improve the wear resistance of steel (hardness of HRC6468). Another part of tungsten dissolved in the matrix, increase the hardness of steel red.High speed steel can reach 650 degrees of red hardnessHigh speed steel has good strength and toughness, cutting edge is sharp after grinding, and its quality is stable. It is used to make small and complex cutting tools

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: 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: Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!: Hard alloy is too high and can not be polished by ordinary metallographic sand paper. It should be put on the machine tool by diamond grinding wheel, and the cost is also very cheapReally manual grinding, then you can add grinding cream to try, but the efficiency is very low

Q: My uncle is a hard alloy round bar. Can you tell me where to use an alloy round bar?: I have some hard alloy round bars (tungsten steel) and high speed steel round rods (all used for cutting tools). Now I want wire cutting, laser, diamond, wire cutting
