Description
Ferro silicon is iron alloy composed of iron and silicon.With coke,scrap,steel,quartz(or silica) as raw material,ferro silicon is made of electric furnace.Because silicon is easy to combine with oxygen to
form silicon dioxide,so ferro silicon also can be used in steel making as deoxidizer.At the same time ,
ferro silicon also can be used as an alloy element joining agent ,widely used in low alloy structural steel,
spring steel ,bearing steel ,heat-resistant steel and electrical silicon steel.Silicon in the ferro alloy production and chemical industry,commonly used as a reducing agent.
Application
1. Ferrosilicon is often used as deoxidizer in steel- making.
2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
3. It can be used as a reductant in ferroalloy production and chemical industry.
4. In iron industry it can be used as inoculant and nodulizer.

- Q: Carbide cutters can work on materials of higher hardness
- This problem is too general, and hard alloy processing range is very wide (it also has many kinds of material), from soft aluminum alloy, copper alloy to HRC60-70 degree of mold can process, the key is to see what you want to process materials
- Q: How to detect carbide material is raw material or recycled material, what is the difference?
- High priceGenerally, the size of recycled materials is poor, and the finished products are not stable. The price is relatively cheapIn general, carbide factories have specialized testing equipment
- Q: Carbide coated drill bit will reduce the service life after grinding, how to avoid?
- 1. carbide drills are generally worn in the back. Then it has little influence on service life.2., the high strength of the workpiece material, easy to cause the front of the drill (spiral groove) wear, bit life impact.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.5., the drill can be re coated after grinding, pre treatment should be done before coating. To increase the coating effect.
- Q: HSS clip can clamp the hard alloy saw it
- The cutter head is mounted on the cutter body and the grinding cutter is called an internal grinding type; the cutter head is individually worn on the fixture and is called external grinding type.Indexable(indexable tools): this kind of structure has been widely used in face milling cutters, end mills and three edged cutters.Product classificationTooth milling cutterA narrow blade is sharpened on the flank to form the back angle, and the cutting angle is reasonable, and the service life is higher. Sharp cutter tooth back straight, curve and line 3 forms.
- 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: Is nickel base alloy hard alloy?
- 3, YW---- tungsten, cobalt, titanium, tantalum alloy products. Titanium is a rare metal, characterized by its light weight, high strength and good corrosion resistance. Because of its stable chemical properties, good resistance to high temperature, low temperature, strong acid, alkali resistance, as well as high strength and low density, has been praised as "space metal"". YT alloy and YW alloy have better properties than YG because they contain titanium.Nickel based alloys are not hard alloys, but they are the best materials for heat and acid corrosion, without magnetism.
- Q: Material properties of Cemented Carbides
- Hard alloy with high hardness of refractory metal carbides (WC, TiC) micron powder as the main ingredient, with cobalt or nickel (Co) (Ni), molybdenum (Mo) as the binder, powder metallurgy products in vacuum furnace or hydrogen reduction sintering furnace. IV, B, V, B, VI, B group of metal carbides, nitrides, boride, etc., because of hardness and melting point is particularly high, collectively referred to as cemented carbide. The structure, characteristics and application of hard gold content are described with carbide as the key point. IV, B, V, B, VI, B group metals and carbon formed in the metal type carbide, because the carbon atom radius is small, can be filled in the gaps of the metal lattice, and retain the original lattice form of metal, forming interstitial solid solution. Under appropriate conditions, such solid solution can continue to dissolve its constituent elements until it reaches saturation. Therefore, their composition can change in a certain range (such as the composition of titanium carbide in TiC0.5 ~ TiC changes), chemical formula does not conform to the rules of valence. When the dissolved carbon content exceeds a certain limit (such as titanium carbide in Ti: C=1: 1), the lattice type will be changed, the original metal lattice metal lattice into another form, then the interstitial solid solution called interstitial compounds.
- Q: What type of carbide is the most ductile?
- Cemented carbide material with tungsten and cobalt carbide toughness is better, at present the carbide grade in the most toughness of YG15. The relation between cobalt content and toughness is shown below. It can be seen that cobalt content and 13%-16% toughness are the best. In this interval, only YG15 cobalt content is 15%.
- Q: What are the common kinds of cemented carbides?
- Cemented carbide is a hard particle of refractory metals (tungsten, tantalum, titanium, molybdenum, etc.) that is mixed with one or more iron elements (cobalt, nickel, or iron), pressed and molded, and then sintered. Types and properties of cemented carbides: (1) classification and grade of cemented carbides. Tungsten carbide cobalt carbide is mainly composed of 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 is a tungsten cobalt carbide that represents an average WCo = 8% and the remainder is tungsten carbide. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide, titanium carbide (TiC) and cobalt. The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide. For example, YT15 represents an average WTi = 15%, while the others are tungsten titanium cobalt carbide with tungsten carbide and cobalt content. The tungsten titanium tantalum (NB) hard alloy is the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.
- Q: The difference between cemented carbide and tungsten.
- The market is usually called tungsten carbide, the two are the same, and the high speed steel called high speed steel. This is the old habit of name of state owned enterprises.
