1. Structure of Magnesium granule Description：
Deoxidizer. Removing the oxygen in molten steel in the process of steelmaking, some ferroalloy can removing the other impurities such as sulfur, nitrogen in steel.
Additive in alloy. According to the requirements of steel composition, adding alloying elements in the steel to improve the performance of the steel.
Inoculant. In front of the cast iron casting in molten iron, improve the crystallization of castings.
Reducing agent to the metal thermal reduction process in the production of other alloy and nonferrous metal reducing agent; Non-ferrous alloy alloy additive; Also a small amount of used in the chemical industry and other industries.
All steel, steel capital is a kind of ferroalloys, it also makes the iron alloy is the most widely used, dosage biggest alloy.

5. FAQ
Also put some iron with high carbon content in high school textbooks and all the iron alloy is called ferroalloy.
- Q:What is the coefficient of thermal expansion of cemented carbides?
- Carbide is also divided into many grades, so the coefficient of thermal expansion is not exactly the same.
- Q:Which prawns know of what is called red hard alloy.
- In the hot state of the object, between the temperature of 500 to 1200 DEG C. The temperature rises, objects will be converted to red by incandescent state. The object is heated up to the state called red red.
- Q:Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?
- 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.
- Q:hard alloy ball tooth, sand making machine, high quality and inexpensive alloy (*^__^*)I am now in great demand of cemented carbide rods, hard alloy blade, hard alloy ball tooth, sand making machine alloy strip, the old customers are not do, now I want to find a long-term cooperation partners, we have not recommended ~ ~ ~ thank you pull

- Q:What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?
- 1.p stands for ferrous metals suitable for working long cuts.2.p30 is suitable for working steel, cast steel, long cut malleable iron. Suitable for general rough machining.
- Q:What is hard alloy steel?
- Modern ultra hard alloys are produced by sintering of carbides of tungsten carbide and some other elements. It is the hard metal (tungsten, tantalum, titanium, molybdenum, etc.) carbide carbide particles, with one or several iron elements (cobalt, nickel or iron) powder mixed, pressed molding, and then made by sintering.Cemented carbide is the most powerful alloy in the world at present. Hard alloy widely used now has two main categories: the first is to do the cobalt WC alloy binder; the second is to make titanium carbide alloy tool steel binder.Cemented carbide is used as a tool, and its hardness will not decrease even at high temperatures of 1000 degrees. Therefore, for high speed cutting, cutting speed up to 2000 meters per minute, 100 times higher than the ordinary carbon steel cutter, tungsten steel cutter is 15 times higher than. The mold made of it can be punched about 3000000 times, which is 60 times longer than the ordinary alloy steel die.
- Q:Can carbide drills be used for high speed steel twist drills?
- Now, like OSG's drill, mainly carbide based.
- Q:What is the specific gravity of cemented carbide?
- The carbon content of WC theory is 6.128% (atom 50%). When the carbon content of WC is greater than the theoretical carbon content, the free carbon (WC+C) appears in WC. The existence of free carbon leads to the growth of WC grain around it, resulting in uneven grain of cemented carbide. General requirements of tungsten carbide compound carbon high (more than 6.07%), free carbon (less than 0.05%), the total carbon depends on hard alloy production process and use scope.Under normal circumstances, the total WC carbon content in the vacuum sintering process of the paraffin process is mainly determined by the combined oxygen content in the block prior to sintering. An oxygen content should be increased by 0.75 parts of carbon, that is, WC total carbon, =6.13%+ oxygen content,% * 0.75 (assuming the sintering furnace is neutral atmosphere, in fact, most of the vacuum furnace is carburizing atmosphere, and the total carbon content of WC is less than the calculated value).At present, China's total carbon content of WC is roughly divided into three kinds: paraffin process, vacuum sintering, the total carbon content of WC is about 6.18 + 0.03% (free carbon will increase). The total carbon content of WC for hydrogen sintering of paraffin process is 6.13 + 0.03%. For rubber process, WC total carbon =5.90 + 0.03% is used for hydrogen sintering. The process is sometimes interleaved, so the determination of WC total carbon should be based on specific circumstances.
- Q:What are the types and types of carbide inserts?
- This problem suggests that you find a famous brand of knives, and then ask for a sample of knives to understand, such as the three high, Walter, Kenna and so on. Because this thing has many points, can not simply understand. According to the processing equipment, it may be divided into carbide inserts for lathe cutting, carbide inserts for milling and carbide inserts for boring. According to the different processing materials, can be divided into non-ferrous metal, used for cast iron, alloy steel. It can also be classified according to the materials used in carbide inserts, such as cubic boron nitride. A thorough understanding of the proposals used. The carbide blade is a general term (outlined) that covers too wide a range of types and models. Just like you ask, "what's the Chinese surname? What's the name?"". Unanswerable.
- Q:What are the types, codes, and range of application of cemented carbides?
- Many domestic brands, mainly diamond brand based, and now there are many new brands, YS/YL/YW/YG10X/YG6X/ many, if you need, I send a detailed table to you!
