Q:Carbide according to the structure of the words, what can be divided into?

The microstructure of the hard alloy, and can be divided into structural and non uniform structure, which contains many kinds of non uniform structure, such as the gradient structure of hard alloy and hard alloy honeycomb structure, the special non hard alloy uniform structure is applicable in industrial production should be stronger than ordinary hard alloy.

Q:Use of waste cemented carbide

Two, crushing methodFor hard alloy containing drilling is not high, because the hardness is relatively low, can use manual or mechanical means broken to a certain fineness in wet grinding mill for a period of time, to reach a certain size for reproduction of hard alloy. This force is a method has the advantages of simple process, short process, low energy consumption, no pollution to the environment, but often in the manual crushing hard alloy, metallic materials due to debris into the tools have broken material pollution, in addition, due to the hard alloy drill containing high amount of easily broken, mechanical crushing method is very limited; cemented carbide complex material by this method is also very difficult to ensure the quality of recycled products. Process method: artificial crushing is broken, crushed into powder 200 mesh or using bulk of hard alloy ball mill for crushing strikes the ball, then add in the bjm alcohol in wet grinding, and then enter the remanufacturing process of hard alloy.Some companies use cooling method: first crushing waste hard alloy in a muffle furnace heated to 80 above this immediately into the water quench, resulting in hard alloy cracking, and then enter the mechanical crushing process. This force is a method in the last century in 90s in Hebei Province Qinghe to gain popularity, there were dozens of county size ranging from recycling plant using the recycled and processed hard alloy, hard alloy processed over a thousand tons of annual production, the total output value of 300 million yuan, becoming one of the local pillar industry. At present, there is still a certain space for development of the crushing method, and the crushing method still needs to be improved by adopting more advanced and clean crushing equipment or by means of the force method which does not destroy the microstructure of cemented carbide with high efficiency.

Q:What materials are ZK20 cemented carbides processed?

ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic

Q:Classification of Cemented Carbides

Cemented carbides are classified into tungsten, cobalt, tungsten, titanium, tungsten, titanium, tantalum and cobalt. Tungsten cobalt carbide knife with: YG6, YG8, YG8N and so on, such carbide cutting tools for processing non-ferrous metals, stainless steel, cast iron and other materials;Tungsten carbide hard alloy knife has: YT5, YT15, etc., this kind of carbide cutting tools for processing steel and other tough materials;Tungsten, titanium, tantalum, cobalt carbide knife with: YW1, YW2, YS25, WS30, etc., this kind of carbide cutting tools for processing heat-resistant steel, high manganese steel, stainless steel and other difficult materials.

Q:How are hard alloy fittings machined and polished?

The fittings are then polished with a vibrating grinder!

Q:What are the differences in performance between cemented carbide cutting tools and PCD cutters (polycrystalline diamond)?

PCD has a very high hardness, but its toughness is not as good as carbide, much lower than high-speed steel, therefore, the main failure form of PCD cutting tool is cutting edge.PCD cutters can effectively process non-ferrous metal materials and non-metallic materials. Such as copper, tungsten and other non-ferrous metals and their alloys, ceramics, hard alloy, various fiber and particle reinforced composite materials, plastics, rubber, graphite, glass and wood, but the diamond is not suitable for cutting steel and other iron materials.

Q:What are the standard units of measurement for carbide inserts?

It used to be priced by KG, and now it's on a tablet basis

Q:What is called cemented carbide?

In addition to carbon atoms, a nitrogen atom and void boron atoms can enter the metal lattice, formed interstitial solid solution. With the properties of mesenchymal type carbide. They are similar to electrical and thermal conductivity, high melting point, high hardness, brittleness and is also large.The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is bonded metalIs 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 degrees. In addition, nitrides, borides, silicides of transition metals have similar characteristics, can also act as a hardening in hard alloy the phase hardening phase due to the existence of alloy with high hardness and wear resistance.Bonding metals are generally iron based metals, and cobalt and nickel are commonly usedManufacture of hard alloy, the size of raw powder in 1 ~ 2 microns, and high purity. 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 then, after drying and sieving to prepare a mixture. Then, the mixture granulation, pressure type, heated to the melting point of the metal bond (1300 to 1500 DEG C) when hardening phase and bonding metal to form eutectic alloy. After cooling, the hardening phase distribution in grid bonded metal composition in each other closely together, form a firm whole. The hardness of the hard alloy depends on the hardening phase content and grain size, the hardening phase content is higher, more fine grain, hardness is greater. The toughness of cemented carbide by bonding metal bonded gold decision. The higher the content, the greater the flexural strength

Q:What are the types, codes, and range of application of cemented carbides?

Many domestic brands, mainly diamond brand based, and now there are many new brands, YS/YL/YW/YG10X/YG6X/ many, if you need, I send a detailed table to you!

Q:What is the hardness of YG8 cemented carbide?

The hardness of cemented carbide tools is generally between 89~92.8, such as the hardness of YG8 is HRA89, the hardness of YT30 is 92.8, and the hardness of YT15 is 91.
