FerroSilicon--70 Percentage  Content Chinese Supplier

 

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: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
Q:Can hard alloy be made into barrel?
No, hard alloy too hard too fragile, not processed, there should be a rifle barrel, it is difficult to machining.
Q:What industry does carbide belong to? Five
The original should belong to the tool industry, because the use of hard alloy cutting tools, cutting tools, do some, such as measuring. Now the application of cemented carbide is becoming more and more widespread, and it should be more machining.
Q:Tungsten steel could be used to do is hard alloy knife?
Of course you can need what specifications of tungsten steel knife
Q:High end markets for cemented carbides
In 2007, 16 thousand and 500 tons of cemented carbide produced in our country, 4500 tons were used in cutting tool production, and the quantity was quite similar to that in japan. But the value of the tool is only 800 million U. S. dollars, far less than Japan's 2 billion 500 million U. S. dollars, which fully shows that the overall production level of domestic carbide efficient tool is still quite a gap with foreign countries. Therefore, in the domestic enterprises can not meet the market demand under the premise of the manufacturing industry will have to rely on a large number of imports to solve. Data show that the main foreign market in China's high-end cutter sales growth rate of 30%, has exceeded the average annual growth rate of domestic knives.
Q:Why is carbide cutting tools less standard than high speed steel cutting tools?
Because the hard alloy material rigidity is better, the brittleness is bigger, the toughness is relatively bad, namely is easier than the high speed steel cutting tool to break off, after grinding blunt, the force is more complex. Greater resistance.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. Now, the cutting speed of new carbide tools is several times that of carbon steel. Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
Q:Classification of Cemented Carbides
Baidu Encyclopedia of hard alloy introduced very clearly
Q:What does WC refer to in cemented carbides?
Of or relating to an alloying element that is tungsten carbide.Tungsten cobalt carbideThe 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:How hard metal is welded with stainless steel?
Oxyacetylene brazing, using copper wire dipped in copper flux, brazing carbide and stainless steel.
Q:What does carbide K15-K20 refer to?
Cemented carbide K15, K20General K stands for cemented carbide ISO grades; generally used to process Cast Iron and non-ferrous metals15 represents its abrasion resistance or impact resistance,
