products details:

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:Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?
Now on the market scrap carbide blade about 100 yuan / kg, depending on the alloy composition, trading area and fixed.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.
Q:How are hard alloy fittings machined and polished?
Cutting tools or ceramic cutting tools for cubic boron nitride material, cobalt alloy cutting tools, etc.,Diamond grinding materials for polishing.
Q:How many temperature can the carbide valve seal reach?
The 425 degree here means that WCB carbon steel can withstand such high temperatures and has little to do with sealing. In the sealing surface location, surfacing, etc., is the role of erosion resistance. If your body can only withstand 200 degrees, but your valve that can withstand 1000 degrees, which makes sense? So resistance to temperature is a comprehensive concept, and the temperature depends on the lowest temperature resistance in all of your parts (somewhat similar to the cask theory in economics). Of course, scouring will be a little faster at high temperatures.
Q:Is nickel base alloy hard alloy?
2, YT--- tungsten cobalt titanium alloy products, applicable to coarse, carbon steel and alloy steel uneven section in interrupted cutting when the YT5 rough planing, semi finishing, discontinuous surface rough milling and drilling.
Q:Hard alloy die mold grinding angle how slim
The diamond electric grinding head can be polished, and the electric grinding head has a conical grinding head. Place the grinding head on a drill press or polish on an electric tool. Can the hard alloy die is caught in the lathe, grinding with diamond file.
Q:Can ceramic tools process cemented carbides?
No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
Q:Can hard alloy be used in food?
Yes, but try not to use regular brands to choose special non-toxic ingredients.
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: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 to polish and polish cemented carbide? Five
Hard alloy is too high and can not be polished by ordinary metallographic sand paper. It should be put on the machine tool by diamond grinding wheel, and the cost is also very cheapReally manual grinding, then you can add grinding cream to try, but the efficiency is very low
