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: Y represents the metallurgical (Yejin) Department standard. W stands for universal (Wanneng) alloy: Ha ha, I'm good at that!HC is the sign of the attractive magnetic force of the alloy, and HRA is the sign of hardness. COM is the cobalt magnetic mark of the alloy. D is the density of the alloy. The general quality certificate of the alloy product will have three indexes above

Q: What type of carbide for punching dies? Better. Where can I buy it?: 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: Explain from the materialGeneral modelIf you buy itWhat parameters are provided?: Tungsten is on the hard alloy with tungsten carbide as the main (academic called tungsten based alloys), we called the daily hard alloy is usually tungsten based alloys, namely tungsten steel.There is another type of cemented carbide called titanium based cemented carbide, commonly known as "cermet"Buy it to shape (such as rods, blade), size and material (on behalf of the main chemical composition and particle size, but apart from a small number of national standard grade, most of them are the enterprise's own brand), and if you need special requirements (such as with cooling hole two 30 degrees within the spiral angle).

Q: High end markets for cemented carbides: Chinese tool enterprises through continuous learning and strategic planning, has occupied half of the country, but in the market, enterprises in the development process and highlights several fatal problems, such as inadequate attention, improper handling, all these will seriously affect the development of enterprises.At this stage, carbide cutting tools in developed countries have accounted for the dominant position of the tool type, the proportion of up to 70%.

Q: Use of waste cemented carbide: Two, crushing methodFor hard alloy containing drilling is not high, because the hardness is relatively low, can use manual or mechanical means broken to a certain fineness in wet grinding mill for a period of time, to reach a certain size for reproduction of hard alloy. This force is a method has the advantages of simple process, short process, low energy consumption, no pollution to the environment, but often in the manual crushing hard alloy, metallic materials due to debris into the tools have broken material pollution, in addition, due to the hard alloy drill containing high amount of easily broken, mechanical crushing method is very limited; cemented carbide complex material by this method is also very difficult to ensure the quality of recycled products. Process method: artificial crushing is broken, crushed into powder 200 mesh or using bulk of hard alloy ball mill for crushing strikes the ball, then add in the bjm alcohol in wet grinding, and then enter the remanufacturing process of hard alloy.Some companies use cooling method: first crushing waste hard alloy in a muffle furnace heated to 80 above this immediately into the water quench, resulting in hard alloy cracking, and then enter the mechanical crushing process. This force is a method in the last century in 90s in Hebei Province Qinghe to gain popularity, there were dozens of county size ranging from recycling plant using the recycled and processed hard alloy, hard alloy processed over a thousand tons of annual production, the total output value of 300 million yuan, becoming one of the local pillar industry. At present, there is still a certain space for development of the crushing method, and the crushing method still needs to be improved by adopting more advanced and clean crushing equipment or by means of the force method which does not destroy the microstructure of cemented carbide with high efficiency.

Q: Dalian enterprises now need 16.3 and 19.3 mm in diameter, the whole cold hard alloy bit, where can I find buyers? Leave a contact: I know Zhuzhou Hua tungsten seems to have what you need. I suggest you go to see their company

Q: What are the fields of nano WC Cemented Carbides applied?: (4) medical application. The drill is a fine medical instrument, the incision must be sharp, but also has good abrasion resistance and toughness, application of ultrafine grain WC hard alloy with high strength, high toughness and wear resistance in this field widely. (5) other applications. Nanocrystalline WC hard alloy because of its fine grain, as the cutting tool can grind the cutting edge radius and high precision, sharp nose arc; because of its high strength can be used for making fine tool rake angle, feed rate and small amount of snacks knife, such as small diameter cutter, reamer etc. because of its high elasticity; modulus and friction wear properties, can be used for the production of high precision mould, punch etc.; also can be used for the production of high wear resistance, erosion resistance, such as high-pressure nozzle, valve, high-pressure gun, glass cutter, cutter and textile tape, tape cutter etc.. In addition, scientists are developing circular tools, rock drilling tools and nano WC-Co based reinforced composites. Therefore, the development of nano WC cemented carbide and the search for wider applications become the focus of development, and the key technology of preparation is the preparation of nano powder and the subsequent sintering process. Particle size is to improve the performance of WC-Co hard alloy (strength, hardness and wear resistance of the Jun effective way, therefore the development of nano cemented carbide is the development focus of the next phase of the study, it will greatly broaden the application field of WC-Co hard alloy, and thus lead to a variety of precision instruments, mold, tool and electronic communication technology rapid development.

Q: The use of wire cutting cut a knife head rest wear found with magnetic iron absorption, cutting.: No, cemented carbide is mostly used as a knife head and has never seen a turning tool. It can also absorb ironBecause this is caused by friction, when the metal friction, so that the movement of free electrons become regular, resulting in a magnetic. If you want to remove the magnetism, you must make the motion of the free electrons irregular. For example, force, heat, etc.

Q: YW2 carbide blade type: YW2 general cylindrical turning tool head type: A325 20pcs

Q: Why carbide fracture?: Hard alloy is made by casting sintering of tungsten and cobalt, nickel, titanium and tungsten powder, cobalt and nickel matrix, and it is easy to break a bonding metal, quality and technology, process equipment, but also related to the amount of metal content and bonding, in short, hard alloy production is very complex, the quality is strictly, in order to produce good toughness, wear-resistant tungsten is a long-term process of exploration, experiment, a link may not have a good grasp of the products are not qualified.
