FeSi is used as a source of silicon to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel; ferromanganese, spiegeleisen, silicides of calcium, and many other materials are used for the same purpose. It 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.

FACTORY:

High Class Of FeSi As Deoxidizer

Q: Are there any German products called K44 which are imported into cemented carbide materials? I am machining hole, K44 is better than domestic material K30?: Yes, K44 is a German cobalt collar carbide material.German cobalt collar is the world's third largest rotating cutter manufacturer, with more than 100 years manufacturingCobalt collar: metal hole cutting tool history, including in the United States, Britain, Brazil, Japan, Korea, Czech and other nineteen countries set up factories. The main production, sale and repair all kinds of metal hole cutting tools, all of its main equipment imported from germany. At present, the tool grinding, grinding and grinding center has a modern five axis CNC intelligent cutting tool grinder,The automatic coating equipment and precision universal cutting tool measuring equipment which can be coated with many kinds of coatings, is mainly responsible for grinding, grinding and grinding all kinds of high speed steel and grinding hard alloy milling cutters and hole cutting tools.

Q: YW1 what do you mean by "YW" in carbide cutter head?: You can go to Zhuzhou tungsten alloy online to see them, there seems to explain in detail

Q: What kind of material is the alloy drill bit?: the hardness is relatively high, generally above HRC90 degrees, and it is suitable for batch processing and hard processing!

Q: What kind of cemented carbide is the most wearable?: Carbide wear is due to the grain size and the cobalt content determines the finer granularity of cobalt content is lower, the higher hardness and lower hardness should be mentioned is the selection of wear-resistant hard alloy not only the hardness to see the use of general cutting hard alloy material with YW2 a relatively high hardness but if the working conditions impact operations more frequently if it should take into account its toughness but the toughness and hardness is conflicting under such circumstances can choose the class YG fine grain alloy

Q: Is there any pollution in the production of cemented carbide?: The chosen of mask filter is good, also want to close modified ah buy mask anti fog and haze, one can see the standard, can be seen in the two to see that the filtration efficiency standards, should be the most familiar N90, N95 series of mask 3X brand, which is based on NIOSH standard name. In addition to the NIOSH standard, common and ASTM ASTM standard, China standard KN and the European FFP standards, can be used to measure an important indicator of masks, medical masks ordinary cheap, protective also poor, it is only suitable for ordinary nurses or at home cooking; and senior medical masks are surgery the doctor or dentist, the doctor does not care about the higher income, cost is low and the mask, pay more attention to the quality of respirator. The high grade medical mask has excellent barrier to particles and fluids, and ensures breathability and breathability in a precise working environment. Can deodorant ah, city toxic particles source: the first is the automobile exhaust the United States imported medical masks Hiroe server Hin, filter, not only anti particles but also prevent droplets. The particles as small as 0.1 micron filtration efficiency up to 99.8% of bacteria or virus vector as small as 0.3 microns (common in droplet) filtration efficiency is up to 99.9%. Using SecureFit patented technology, through adjustment to adapt to different facial shapes, to achieve high consistency, for your health and family, go out wearing masks, in the J good style East, I wish you happiness, hope to adopt

Q: Classification of Cemented Carbides: Cemented carbides are classified into tungsten, cobalt, tungsten, titanium, tungsten, titanium, tantalum and cobalt. Tungsten cobalt carbide knife with: YG6, YG8, YG8N and so on, such carbide cutting tools for processing non-ferrous metals, stainless steel, cast iron and other materials;Tungsten carbide hard alloy knife has: YT5, YT15, etc., this kind of carbide cutting tools for processing steel and other tough materials;Tungsten, titanium, tantalum, cobalt carbide knife with: YW1, YW2, YS25, WS30, etc., this kind of carbide cutting tools for processing heat-resistant steel, high manganese steel, stainless steel and other difficult materials.

Q: Have seen many of the whole alloy cutting tool brand, I would like to ask, the global overall alloy cutting tool brand, which have quality and price advantage, I want to be a cheap brand regional agent!: Brands have Swedish shandeweike, Israeli American Kenna; in accordance with Scafa, second tier brands are MITSUBISHI, Chinese Zhuzhou diamond brand, German Walter, three line brand in Taiwan, South Korea and China's Zigong Great Wall, Zhuzhou Jingcheng diamond card card, Qinghe etc. many, this is not the only one. In short, hard alloy cutter is very complex do you want to say, the light is not enough to know the brand, but also need to learn a lot of tools and machining knowledge of it. Finally, I wish you success!

Q: What materials are hard alloys used to process?: YG hard alloy, impact resistance, high temperature resistant, processing pig iron.

Q: Do you want to center hole? How deep is fit? Or do not hit it directly? My drill bit and the center hole contact point are easy to collapse: Detailed analysis of the specific circumstances, the general drilling site is very smooth, you do not need to hit the center hole. If the borehole is uneven or drilled on the slope, a center hole is required. If the drill hole is first deflected and re corrected, a center hole is also required.

Q: What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?: ISO (International Organization for Standardization) will be divided into carbide alloy P, M, K three categories, P class equivalent to China's YT class, the main ingredient is WC-TiC-Co;In order to be processed in different cutting conditions of material grade, in the P class with 01-50 number between that from the highest hardness to a series of alloys for maximum toughness between P30, roughly equivalent to the YT5 of our country;This kind of cemented carbide has the highest strength and best impact resistance in YT (P), but it has poor wear resistance. It is suitable for intermittent roughing of general carbon steel and alloy steel.
