Product Description:

Calcium and silicon and oxygen has a strong affinity. Especially calcium, not only with strong affinity, oxygen and sulfur, nitrogen has a strong affinity. So the calcium silicon alloy is a kind of ideal compound deoxidizer, desulfurization agent. Silicon alloy not only deoxidization ability strong, deoxidizing products tend to rise, easy to discharge, but also can improve the performance of the steel, plasticity, impact toughness of steel and liquidity. Currently the calcium silicon alloy can be final deoxidization instead of aluminium. Be applied to the high quality steel. In the production of special steel and special alloys. Such as rail steel, mild steel, stainless steel, steel and nickel base alloy, titanium alloy, and other special alloy are available the calcium silicon alloy as deoxidizer. The calcium silicon alloy also for practice of converter steel workshop with increasing agent, the calcium silicon alloy can also be used for cast iron inoculant and additives in nodular iron production.

Broad of ferroalloy ferroalloy Ferroalloys (English), is refers to the steelmaking as deoxidizer, element additives added to molten steel with a particular feature or meet certain requirements of a product. Iron and intermediate alloy composed of one or more of the following elements, mainly used in steel smelting. In the iron and steel industry is usually put all steel used in the middle of the alloy, iron or not (e.g., the calcium silicon alloy), are called "alloy". Habits and some pure metal oxide additives and additives is also included.


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.

Also put some iron with high carbon content in high school textbooks and all the iron alloy is called ferroalloy.

Q:It is hard alloy steel
Tungsten steel and hard alloy: tungsten carbide is the difference is a. Tungsten is raw material for smelting ferrotungsten adding steelmaking process in molten steel for tungsten and also called high speed steel or tool steel, the tungsten content in 15-25%; and the hard alloy is used in powder metallurgy process of tungsten carbide and cobalt as the main body or other binding metal sintering, the tungsten content in general in more than 80%. Simply put, all the hardness go more than HRC65 things, as long as the alloy can be called carbide.
Q:Where can I buy more than 94 hardness carbide cutter head, welding, the best address in detail, thank you!
It's no problem to weld cemented carbide. Please call me when you need it
Q:Zhuzhou Hard Alloy Co. Ltd., Xiamen Jiangxi copper and tungsten, which is better,
Prospects for the development of hard to say, look at individuals, we this profession, if it is small Shuo, the main income is project bonus, this with your personal ability is very large. These two enterprises are similar in terms of welfare benefits. If you're a girl, it's better to suggest a closer home. Jiangxi copper did not understand, ask your elder sister what, to see if there is no inside, we also find out from these companies in Shixiongshijie there, not just listen to HR talk.
Q:How are carbide cutters made? 20
The price varies from a few thousand dollars to a few days depending on the size of the blade and the specificity.Surface coating is usually coated with titanium (such as titanium nitride, etc.)Large manufacturers such as diamond coating equipment general equipment in the tens of millions of yuan in cost is quite high, in Jiangsu there is a foreign company specialized in coating equipment sold to undertake external coating business, the coating cost with you a coated blade is related to the price from a few dollars to tens of dollars / piece / slice.
Q:What are the types and types of carbide inserts?
Your question is really not a simple answer can be got, to see you on what to divide, the blade types according to use classification, can also according to the material classification, and so on, I suggest you go to the official website of Zhuzhou China tungsten alloy has a hard alloy technology knowledge base to see. There's an introduction.
Q:What is the difference between the production process of ferrous powder metallurgy and cemented carbide?
After the Second World War, the rapid development of powder metallurgy technology, new production technology and technical equipment, new materials and products continue to emerge, develop some special materials manufacturing field, has become an important part in modern industry.
Q:What materials are hard alloys used to process?
YG hard alloy, impact resistance, high temperature resistant, processing pig iron.
Q:What type and hardness of grinding wheel 20 for general carbide turning tools?
Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60Another grinder usually holds two pieces. A piece of green silicon carbide, a piece of brown corundum, brown corundum grinding wheel is used for iron, such as the size and hardness of the cutter bar and green silicon carbide as the new knife. You can also choose 46#'s.Luoyang abrasive tools professional sales all kinds of grinding wheel, carbide blade, diamond grinding wheel
Q:What is the consciousness of YG in YG cemented carbide?
For brittle materials such as cast iron, materials such as air cut and cast steel, the YG carbide cutting tools can be used in the cutting process. The wear resistance and impact resistance of these alloys are better
Q:What brand of carbide is used in woodworking tools?
The quality alloy YG6X/YG6A is suitable for the processing of chilled cast iron, alloy cast iron, heat-resisting steel and alloy steel. It is also suitable for the fine machining of precision cast iron and the manufacture of wear-resistant parts. Hard alloy YG8N: is suitable for fine cast iron, ductile iron, white iron and non-ferrous metal finishing.
