products information

Our factory supply 75% 72% 65% 45% four grades of ferrosilicon.

Ferrosilicon has been widely applied.in the steel industry, foundry industry and other industrial production.

Ferrosilicon is indispensable deoxidizer in the steel industry., ferrosilicon is used for precipitation deoxidation and diffusion deoxidation in Ju steel. Brick iron also as an alloying agent used in steelmaking. Adding a certain amount silicon to the steel can significantly improve the strength, hardness,elasticity and permeability of steel, reduce the hysteresis loss of transformer steel.

High ferrosilicon or silicon alloys is used for the production of low-carbon reductant in ferroalloy industry. Adding ferrosilicon to cast iron can be inoculant for ductile iron, and can prevent the formation of carbides, and promote the precipitation of graphite and the nodulizing, so as to improve performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry,and coatings for welding electrodes in the electrode manufacturing.

In the steel industry, one ton of steel consumes about 3 ~ 5kg75% ferrosilicon.

Melting point: 75FeSi to 1300 ℃

Q: Can hard alloy be welded with silver electrode?: Hard alloy can use silver electrode welding, some more liquid silver wire than general tin brass or iron brass, the cost is too high, the strength level than the ordinary copper electrode should be higher, personal suggestions for the selection of copper base up instead of silver electrode, such as the WEWELDING 46 electrode (referred to as Odin Wei 46 If the strength of electrodes), the structure is higher than silver, if it is to achieve the high permeability, it is still the ideal to silver, only from the strength level, is not WEWELDING 46 copper based electrode.

Q: Carbide blade domestic that tricky point?: China's carbide cutting tools must be the best cemented carbide in Zhuzhou.

Q: What are the well-known brands of cemented carbide materials at home and abroad?: A lot of foreign ah, Sweden Sandvik, German - Luxemburg, American Kenna, Israel - Domestic - hard line iscar; diamond, Zigong the Great Wall, Xiamen gol-egret etc.

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: 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: Carbide coated drill bit. Do you have one there?: 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.

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: The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason: The cutter model is wrong, the milling can not move the material, the resistance is big, then the knife breaks. Use 75 degrees to make the plane

Q: I want to process more hard stainless steel, with YC45 this type of carbide knife can do? Where can I buy authentic, know the friend told me, thank you: Hard alloy cutter type very much, every plant can set the brand, you said YC45 brand is a custom factory brand, it is difficult for outsiders to judge. But I can tell you that the cutter international classification process of stainless steel for the M class, the domestic classification as class YW, usually YW2 blade.

Q: What are hard alloys? Which ones are they? How often are they chosen?: It is based on one or several carbides (TiC and WC) as the hardening phase, with carbon steel or alloy steel (such as high-speed steel, chrome molybdenum steel) powder as binder, powder metallurgy materials through proportioning, mixing, pressing and sintering. After annealing, it can be machined. After quenching and tempering, it has the same hardness and high wear resistance as the hard alloy. It can also be forged and welded, and has the characteristics of heat resistance, corrosion resistance and oxidation resistance. The utility model is suitable for manufacturing various tools with complicated shapes, such as twist drills, milling cutters, etc., and can also manufacture moulds and wear-resistant parts which work at higher temperature.
