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:What are the types and specifications of carbide cutters?: Tungsten, titanium, tantalum (niobium) carbidesIs the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. The hard alloy and hard alloy general or universal hard alloy.The grade by "YW" ("hard", "million" Pinyin prefix) and sequence number, such as the YW1. knife head has dozens of specifications, to be enumerated for reference!

Q:What is the relation between the number of teeth of carbide saw blades?: 1., it is mainly used for longitudinal sawing of small diameter logs. According to the size of the pre adjustment, a plurality of sheets can be sawed off at one feed, which is widely used in the sawing process of the front path, small diameter and log sawing of blockboard and finger jointing factories. 2. compared with the band saw, the processing efficiency is high, the precision is high, the operation is simple and convenient, the technical requirement of the worker is not high, and the defects of low processing precision, low efficiency and high operation technical requirements of the band saw are compensated. What is the difference between the 1:40 tooth and the 60 tooth? Because of the small friction, the 40 teeth will save effort, and the noise will be small, but the 60 teeth will be cut more smoothly. A carpenter usually uses 40 teeth. The price is the same, ha ha. For small sounds, use thicker ones, but thin quality is better. The more the number of teeth, the more smooth the cut section. If your machine is stable, the sound will be smaller. What is the difference between the 2:30 wood cut saw blade and the 40 Tooth cut wood saw blade? Main: 1 cutting speed is different. 2 different gloss. The angle of the teeth of the 3 saw blade itself is different.

Q:Is the hard alloy the same as the cemented carbide?: Superhard alloy and cemented carbide are not the same ah.Personally, the alloy feels like a metal of high hardness; for this is not very familiar, there is no right to speak;But the main component of cemented carbide is WC+Co. And some have TIC.TaC. Equal carbide. Basically out of the metal range.So you say cemented carbide and hard metal are different.If it is replaced by superhard materials and cemented carbide to compare. The carbide can be cemented into the superhard material.These are personal views and can be discussed more

Q:How are cemented carbides separated from the cutting tools?: Brazing heating to melt after the pain, you can take off!

Q:I would like to use carbide cutting tools, car work, ordinary A3 steel or 45 steel, lathe speed to play more appropriate, the workpiece surface quality is better?: LZ, I don't know if you did it for eight years or eight years. When you finish the car hit 1600 turn, your knife is a diamond? I'll ask you to open 6 is the number of mid-range lathe wire ah, the general lathe open open 6 mid-range at least twenty-six wire, when you finish turning with so high feed! Even if you use 1600 rpm and this knife, your surface is bright, but your workpiece roughness must be unqualified. Remember, finish is not roughness. You are good at the question. The cutting speed is based on what kind of cutting depth and amount of knife you choose when you rough the car. You don't say the exact size of the part you want to process. That's not good. The key experience is to rely on their own step by step, tired.

Q:K carbide carbide cutting tools, mainly used for turning what materials?: K class brand is the international standard ISO code, equivalent to China's class YG carbide brand, suitable for processing stainless steel, non-ferrous metals and alloys, as well as non-metallic materials, cast iron and other materials.

Q:What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?: Hard alloy is one of the people familiar with the tools and materials, it is very difficult to weld by hard metal carbides (we, Tie) of powder metallurgy with CO, MO and NI as sintering binder. Its mechanical, physical and mechanical properties depend mainly on the kinds of metal carbides, properties, quantities, grain sizes, types and components of binders.In cemented carbides, the proper addition of Tie increases the content of hard Tic, and the higher the hardness of the alloy. The more the content of cobalt in the bonding phase, the lower the hardness of the alloy. Therefore, the hardness of We-Tie-eo alloy is higher than that of We-eo alloy. The hardness of We-eo alloy can be increased by adding Tae or Nbc. The higher the hardness of the cemented carbide, the better the wear resistance, but the lower the strength (bending), and the addition of Tac will improve the blade strength, while strengthening the blade resistance to fragmentation and breakage, fatigue strength also increased. Generally, the higher the hardness, the lower the toughness. In China's Cemented Carbide standard YB850-75, most carbide grades are We-Co (YG) and We-Tie-Co (YT) two.Domestic hardness alloy grade control: GB, brand ISO, P10, P20, M10, M20, K01, K10, K20, K30, domestic uniform brand YT15, YT14, YT5, YW1, YW2, YG3, P30, YG6x, YG6, YG8

Q:What is the consciousness of YT in YT cemented carbide?: YT carbide hard alloy has relatively high hardness, but poor toughness, poor impact resistance. It is suitable for processing plastic material used to machining without quenching medium and low carbon steel, alloy steel and so on.

Q:Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?: Xing bautec supply Foxconn tungsten steel milling cutter, should also be rightWhite steel milling cutter used for low speed turning, workpiece roughness is better than carbide blade! Hard alloy is harder than high speed steel, but hard alloy is more brittle than white steel and easy to break.Hard alloy milling cutters are mainly composed of rare metals.

Q:What is the hardness of YG8 cemented carbide?: The hardness of YG8 cemented carbide produced by Zhuzhou fine drill is 89.5, all of which are made of cemented carbide raw material
