Product Description:

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.

Q:Is nickel base alloy hard alloy?
There are three kinds of cemented carbides used in machining,:1, YG--- tungsten cobalt alloy products, the YG6 is generally suitable for machining cast iron, roughing non-ferrous metals and their alloys and non metallic material during continuous cutting, interrupted cutting of semi fine fine cars and trucks etc..
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:What does "YC20.1 carbide" brand mean?
PaInstead of old products, YT15 YT14A new brand with a slightly higher price of 40%, which has not been done
Q:One can write on the hard alloy on the pencil, what's the name ah, who knows.
Electric spark marking pen. 230 of the price is kind. The power of cemented carbide should be chosen a little larger.
Q:What is the consciousness of YG in YG cemented carbide?
The metal material in machining, hard alloy tool material are the two common categories. Mainly tungsten cobalt tungsten cobalt (YG) and titanium (YT). There are other brands in recent.
Q:HSS clip can clamp the hard alloy saw it
The cutter head is mounted on the cutter body and the grinding cutter is called an internal grinding type; the cutter head is individually worn on the fixture and is called external grinding type.Indexable(indexable tools): this kind of structure has been widely used in face milling cutters, end mills and three edged cutters.Product classificationTooth milling cutterA narrow blade is sharpened on the flank to form the back angle, and the cutting angle is reasonable, and the service life is higher. Sharp cutter tooth back straight, curve and line 3 forms.
Q:How many temperature can the carbide valve seal reach?
This 425 DEG C is the limit temperature of ASTM A216: -30 DEG C - +425 DEG CBut if the sealing surface of rice now is PTFE, it can be as high as +80 degrees centigrade. If the PTFE material is good, it can reach +150 centigradeTherefore, the body material is carbon steel, only that the valve body of the temperature range of this materialLook at the inside of the valve,For example, cryogenic carbon steel in LCB, ASTM, A325 can reach -46 degrees --+340 degrees centigradeHowever, if the sealing surface of your body is the sealing surface of plain carbon steel, the temperature range of this carbon steel valve is only the temperature range of the ordinary carbon steelIf you say that now is the carbon steel valves used in the sealing surface of the safety valve, you must need welding hard alloy (STL or D series, etc.) should have strong hardness of hard alloy after treatment, impact resistance.Depends on your flow channel medium, if it is high temperature, it is best to use 316, and so onThe use of valves is a combination of considerations
Q:How are cemented carbides separated from the cutting tools?
The hard alloy cutter head and the tool body junction part are heated to 600~800 degrees, and the solder can be melted, and the cutter head and the cutter body of the carbide cutter can be separated.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.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.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:How to detect carbide material is raw material or recycled material, what is the difference?
The original material has uniform particle size and stable performance. High priceGenerally, the size of recycled materials is poor, and the finished products are not stable. The price is relatively cheapIn general, carbide factories have specialized testing equipment
Q:The difference between cemented carbide and tungsten.
The market is usually called tungsten carbide, the two are the same, and the high speed steel called high speed steel. This is the old habit of name of state owned enterprises.
