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:Hello I remember carbide knives have several classifications As if it were not the same as it is now, can you tell me the same and different models as before? What material can they make?
- I remember Zhuzhou Hua tungsten. They have a full range of them. You can go to their Baidu company
- Q:Carbide according to the structure of the words, what can be divided into?
- Hard alloy is by grade, can be made into all kinds of special-shaped parts
- Q:Big brother on the 1 floor is exaggerating. It's impossible at all
- If the precision of the thread is not high enough, it can be produced by pressing.
- Q:One can write on the hard alloy on the pencil, what's the name ah, who knows.
- What pen is this?Chasing the answer230 yuan each. You can contact me any time you like.
- Q:How many models are there? 10Because we want to purchase carbide milling cutters, we would like to know the classification methods and the characteristics of various types of carbide at home.Some people say that Zhuzhou is best, Nanchang, Fujian, Longyan in turn. But there are many factories in a region. How can you say which is good and that is not good?Do you have a YL model?
- Overall, Zhuzhou cemented carbide works, Shanghai alloy materials factory, Zigong cemented carbide plant, new carbide knives are good. But the single pair of milling cutters is not clear! There is no YL!
- Q:What is the difference between hard alloy steel and high speed steel?
- 3, hardness is not the same: cemented carbide hardness, especially at high temperature hardness, but high-speed steel toughness better4, can withstand the cutting speed is not the same: due to the red hard high, can withstand higher cutting speed, and high-speed steel is now not high speed
- Q:What's the use of recycling cemented carbide?
- Recycling can be reused ah, and recycling plastics, scrap iron and so on are a reason.
- Q:What material is that ultrafine cemented carbide?
- The main component of cemented carbide is tungsten carbide, so also known as tungsten steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness can reach HRB89 to 95Tungsten steel production process is as follows: the powder is pressed into a blank, and then into the furnace heated to a certain temperature (sintering temperature), and keep a certain time (time), and then cooled down to obtain the required properties of tungsten materials.The characteristics of ultrafine cemented carbide is the main component of WC, compared to the hard phase and general hard alloy, the hard phase particles are very fine (average grain size less than 1um), so you can get a higher than the general hard alloy of the same hardness strength (toughness), edge grinding can be sharper and better wear resistance.
- Q:Is carbide resistant to alkali?
- Hard alloy chemical composition are general acid-base stability, it has no effect on, also has strong alkali resistant corrosion resistant hard alloy sintered hard alloy is added in different metal powders, can improve the hard alloy for corrosion resistance
- Q:What is the hardness of cemented carbide?
- Different grades, different hardness, usually (86 ~ 93HRA, equivalent to 69 ~ 81HRC);
