Ferro Silicon alloy

1. Ferro silicon is produced by reduction of silica or sand with coke in presence of scrap iron, millscale, or other source of iron.

2. Ferro silicon with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferro silicon with higher silicon content are made in electric arc furnaces.

3. An overabundance of silica is used to prevent formation of silicon carbide. Microsilica is a useful byproduct.

4. The melting point and density of ferro silicon depends on its silicon content.

Usage

1. Ferro silicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys.This prevents the loss of carbon from the molten steel (so called blocking the heat);

2. Ferro silicon can be used to make other ferroalloys. Ferrosilicon is also used for manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores.

In the manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization. In arc welding, ferrosilicon can be found in some electrode coatings.

3.Ferro silicon is a basis for manufacture of prealloys like magnesium ferrosilicon (MgFeSi), used for modification of melted malleable iron. Ferrosilicon is also important as an additive to cast irons for controlling the initial content of silicon.

4.Ferro silicon is also used in the Pidgeon process to make magnesium from dolomite.

FeSi Alloy As Good Deoxidizer

Q:I would like to solder a carbide tool now, what materials do you need to ask for specific methods?: You need to use the Ya alloy electrode and welding tool first articles to be heated to red (a temperature of about 800~1000 degrees) and then stained with borax flux (in the electrode when need to add) and then work hard alloy or welded tungsten steel tools a turning tool on the lathe tool holder can be cut off in the car turning bracket that is the

Q:Hard alloy die polishing with what can be reached Ukraine black brightness: What if this need to die, the smaller diameter must be black if the large diameter is bright, with a diamond grinding paste and polishing powder

Q:What kinds of carbide knives do you have? Write out its main functions and uses.: The commonly used cemented carbides are mainly based on WC, and are classified into the following categories whether or not they are added to other carbides:(1) tungsten cobalt (WC+Co) cemented carbide (YG);It consists of WC and Co, has high flexural strength toughness, good thermal conductivity, but poor heat resistance and wear resistance, mainly for the processing of cast iron and non-ferrous metals. YG hard alloy fine grain (such as YG3X, YG6X), in the same amount of cobalt, its hardness wear resistance than YG3, YG6 high strength and toughness is poor, suitable for machining hard cast iron, austenitic stainless steel, heat-resistant alloy, hard bronze.

Q:One can write on the hard alloy on the pencil, what's the name ah, who knows.: Electric spark marking pen. 230 of the price is kind. The power of cemented carbide should be chosen a little larger.

Q:What is the difference between the raw and recycled materials of cemented carbides? The more specific, the better: Raw raw materials are raw materials, recycled materials have been used, and then recycled and re produced, raw materials than recycled materials used, and more pure materials.

Q:Carbide coated drill bit will reduce the service life after grinding, how to avoid?: 1. carbide drills are generally worn in the back. Then it has little influence on service life.2., the high strength of the workpiece material, easy to cause the front of the drill (spiral groove) wear, bit life impact.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.5., the drill can be re coated after grinding, pre treatment should be done before coating. To increase the coating effect.

Q:What are the well-known brands of cemented carbide materials at home and abroad?: Foreign - Sweden Sandvik, Germany - Luxemburg, American Kenna, Israel - Domestic - hard line iscar; diamond, Zigong the Great Wall, Xiamen gol-egret etc..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, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Q:Where can I buy more than 94 hardness carbide cutter head, welding, the best address in detail, thank you!: It's no problem to weld cemented carbide. Please call me when you need it

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!: 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:Make cutting dosage: But modern machining, has no strict distinction between the T and G class, but in different types of processed materials and processing conditions, different ways such as the use of different materials, and with appropriate coating, to reduce the cost requirements.Cutting parameters need to be selected according to different cutting occasions and different materials to be machined.
