Product Description:

FeSi 70 for Casting Manufactural and Steel Making

 

Description of FeSi 70

 

Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke, quartz (or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking.

 

Application of FeSi 70

 

1)As de-oxidation and alloying agent in iron & steel plants.

2)Enhance properties including ductility, strength, rigidity and resistance of steel.

Q:Japan steel tungsten carbide which is good
Japan steel tungsten carbide recommended Kunshan aloi precision mould Co. Ltd, Japan Istanbul technology research of copper tungsten alloy used for professional sales of Japanese steel tungsten carbide and discharge EDM, silver tungsten alloy, copper alloy; discharge EDM tungsten copper, copper thread electrode; non-standard thread electrode, thread grinding machining
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:What are the cemented carbides?
Tungsten cobalt carbideWC cutterThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt.For example, YG8, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.
Q:Where can I buy more than 94 hardness carbide cutter head, welding, the best address in detail, thank you!
I know the downstairs Beijing Tongzhou District Yangzhuang Road No. 22 hospital Deshang with hard alloy salesroom.
Q:What are the fields of nano WC Cemented Carbides applied?
(2) electronic industry. The development trend of electronic products is miniaturization, integration and precision. The integrated circuit board is made of epoxy resin, glass fiber or glass fiber reinforced plastic. This requires micro drill has high hardness and wear resistance; while the drill diameter is very small (generally 0.2 ~ 0.3mm, and 0.05mm), easy to break, also called bit has high strength and toughness, and need to correct drilling hole position accuracy, and the drill bit has high stiffness (elastic modulus). These conflicting requirements. The common hard alloy and fine grain carbide drills are difficult to meet these requirements, only the use of nano grain carbide grain size of less than 0.5 m. And as the dot printing needle, its diameter is only 0.2-0.35mm; multi frame processing integrated circuit lead by the progressive die, punch thickness less than 0.2mm, the error is only 0.002mm; in addition to the printed circuit board with wire cutting head disc cutter, and the precision of the small die, all require the use of Nanocrystalline WC cemented carbide in order to achieve its function to produce alloy.
Q:Are there any German products called K44 which are imported into cemented carbide materials?
K44 never heard of it! All I know is K40.K40 is better than K30, but almost stiff.K40 is suitable for rough machining, and K30 is suitable for finish machining.It's better to process K40 holes in general.
Q:Advantages and disadvantages of cemented carbide bit 5
Long life, than the average speed of life only about 10 times, but the price is high, because the hard, so relatively crisp!
Q:What's the use of recycling cemented carbide?
Recycling can be reused ah, and recycling plastics, scrap iron and so on are a reason.
Q:What is the difference between hard alloy and steel
Cobalt (Co) is used in bonding in the alloy, is in the process of sintering, it can make the tungsten carbide (WC) powder and tightly surrounded Bonded together, after cooling, became hard alloy. (equivalent to the cement content). Usually: 3%--30% tungsten carbide (WC) is the main component of some metal properties of the hard alloy or cermet, the total composition of 70%---97% (weight ratio) is widely used in wear-resistant, high temperature resistance, resistance corrosion, bad working environment of the parts or tool, cutter tools.
Q:How to distinguish the authenticity of Zhuzhou diamond brand cemented carbide blade?
Zhuzhou diamond brand cemented carbide blade is the first brand in our country. We can distinguish its authenticity from the following aspectsVisual package: it is packed in plastic box, the upper and lower cover are transparent plastic, and the bottom box is blueNormative labels: according to the ISO standard, lists the recommended types of processing materials, bar code identification, marked "diamond brand" trademark and "China well-known trademark" and enterprise logoType anti-counterfeit: each piece of hard alloy welding machine, clamping blade convex superscript "ZCCT" logo, direct press formingSealing anti-counterfeiting: labels and sealing paste affixed to the interface of the packaging box, one-time paste, can not be pasted after tearingZhuzhou Jing Jing carbide sales Co., Ltd.
