Application

Chrome is always used to improve the antioxidation and corrosion resistance of steel to make the surface of steel after it is oxidized to form strong adhension oxide film. Then it stops being oxidized or decelerates being oxidized.Micro-Carbon ferro chorme is applied to making stainless, acid-resistant steel and heat resistant steel.

Q: Detailed comparison of cemented carbide with diamond properties: Hard alloy is a metal, usually refers to the number of tungsten carbide hard alloy components, there are many brands, such as YT YG series, this is found, it is mainly used as the traditional machining industry, a cutter head, tools, etc., our common lathe tool tip is above the hard alloy. The largest hard alloy base China in Hunan Zhuzhou tungsten group, a few years ago by Minmetals acquisition. Diamond is a non-metal is allotrope of carbon, he is by far the highest hardness of substances found in nature. Synthetic diamond, also known as industrial diamond, has developed rapidly in China in the past ten years. Its total output has accounted for more than 90% of the total amount of the world. With diamond related diamond tools, mainly used in the field of drilling, cutting, grinding, polishing, grinding, geological, stone, construction, industrial processing, precision instruments, aerospace, electronics, also known as super abrasive, and he (ordinary abrasive corundum and silicon carbide) called industrial teeth "plays a vital role in the economic development of Chinese.

Q: What are the main items of cemented carbide production process and finished products inspection, as well as the price of testing equipment, equipment and equipment?!! Please experts advice and answer, the younger brother will be grateful!!!!!!: The school's equipment, the majority of the real carbide testing equipment used to study and learn from students, is not equipped with what you see,If you want the most common words, use the following set of scenarios1, magnetic, magnetic saturation instrument, there are also Hunan Normal University2 domestic Hengping density meter3 Ji'nan test the strength of machine4 Rockwell hardness can be used in Shanghai material factory5 Shanghai 5 optical microscope can also plant or lightMetallographic sample preparation equipment can be used in Shandong, Laizhou6 carbon oxygen equipment can be used by Beijing ng7 Scott velocity loose can only buy Beigang HospitalIf you want a mid-range or advanced point, you can add me to chat, and rest assured that I am not selling equipment, and in this line I have been doing it for 10 years

Q: Welding hard alloy cutter, hard alloy cutter, high speed steel, ceramic knife head head are what are the advantages and shortcomings?: The advantages of carbide drill can drill more hard material, the disadvantage is to be good grinding, grinding is not good, easy to break the edge, two main cutting edge height and angle equivalent, it is best to use the grinding machine.

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: In addition to diamonds, Hunan there are no good carbide manufacturers? Product advantages in the ordinary blade, knife head and mining tools. Which factory's alloy is of good quality? The best size, with the original tungsten powder. Please know what to say, first thank you: Looking for packing box manufacturers can find the letter plastic

Q: Carbide cutting insert: Brand in general can be found above, but you can also go to Zhuzhou tungsten tungsten alloy to see, they have good quality there

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: What does American standard cemented carbide grain size C mean?: In addition to carbon atoms, nitrogen atoms and boron atoms can also enter the voids in the metal lattices to form interstitial solutions. They are similar to those of interstitial carbides, which can conduct electric conduction, heat conduction, high melting point, hardness and brittleness. The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is a bonding metal. Is the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 DEG C. In addition, transition metal nitrides, boride and silicides have similar properties and can also act as hardening phases in cemented carbides. The presence of the hardened phase determines the alloy's extremely high hardness and wear resistance. Bonding metals are generally iron based metals, and cobalt and nickel are commonly used. In the manufacture of cemented carbide, the size of the raw material powder is between 1~2 microns and the purity is very high. Raw materials according to the provisions of the proportion of added alcohol or other medium in the wet ball mill in wet grinding, making them fully mixing, crushing, drying, sieving after adding wax or gel forming agent of a class, and then drying and sieving to prepare a mixture.

Q: What are the fields of nano WC Cemented Carbides applied?: Nano WC-Co hard alloy, because of its special wear resistance, high hardness, and fracture toughness and excellent compressive strength have been widely applied in various fields of modern technology, has been made of integrated circuit board micro drill, dot matrix printer print needle, hole processing tools, woodworking tools, precision mould, drill, hard processing materials tool etc.. The main applications are summarized as follows: (1) metal working. At first, the development of sub micron WC hard alloy is to solve the high temperature alloy hard to machining processing materials, modern nano WC hard alloy is superior in strength and toughness of sub micro alloy, and therefore more suitable for high temperature alloy, titanium alloy, stainless steel, spraying (welding) processing materials, quenching steel, chilled cast iron etc.. The nano WC cemented carbide breaks through the limit of the bending strength of ordinary cemented carbide, which is far lower than that of high speed steel. Its application has been extended to the field of high speed steel.

Q: Is the hard alloy the same as the cemented carbide?: Is essentially the same, are two kinds of powder alloy materials, but the composition is different, its processing performance depends on the alloy material of concrete, in my experience, super hard alloy toughness than hard alloy with high hardness, but lower than the hard alloy, don't be misled by the literal meaning, the word super tool hard alloy generally refers to add the other ingredients of high speed steel the hardness wear resistance than ordinary high speed steel (of course not hard alloy) without losing the advantages of high speed steel toughness.
