Ferro Silicon Used For Steel Making CNBM China

Q: How to polish the rough surface of cemented carbide, what is the shortcut? Seek expert advice. Thank you。: Carbide parts polishing machine, professional solutions to all kinds of precision parts polishing technology problems

Q: What kind of material is the alloy drill bit?: the hardness is relatively high, generally above HRC90 degrees, and it is suitable for batch processing and hard processing!

Q: The use of cemented carbides YG and YT: Two, titanium is a rare metal, characterized by light weight, high strength and good corrosion resistance. Because of its stable chemical properties, good resistance to high temperature, low temperature, strong acid, alkali resistance, as well as high strength and low density, has been praised as "space metal"". YT alloy and YW alloy have better properties than YG because they contain titanium.

Q: Carbide coated drill bit will reduce the service life after grinding, how to avoid?: Hello, there is no way to avoid the problem of reducing the service life of the carbide coated drill bit after grinding;Cemented carbide bit, in its use, the surface coating, the blade has already been damaged, can not reach the integrity of the factory, so that it affects the service life of the drill bit,There is a need to be re grinding, coating, the coating has physical and chemical coating and coating, coating chemical now use more chemical coating basically is the tool coating at high temperature, so the temperature can cause 2 damage of cemented carbide substrate;So it also affects the service life;The effect of bit life, the most important is the geometric design of drill bit; before the design is not good, but when re grinding and grinding a good point, sometimes improve the service life, but the original drill must use will reduce the life of the;About those problems mentioned above, in fact, that is, some methods to improve the service life of the drill, upstairs can refer to

Q: Big brother on the 1 floor is exaggerating. It's impossible at all: If it needs higher precision, it can only be machined with internal thread grinding machine. It can be used for grinding different specifications of thread, and the efficiency is higher than that of electric pulse, and the size is goodSpecific processing, you can contact me in detail

Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?: The bending strength of YG20 can reach 2500, which is suitable for making stamping dies. The bending strength of YG15 and JK13 can reach 2550, and the bending strength of JK15 can reach 2600, but the wear resistance is lower. The flexural strength of JK1 is 2500, and it has good wear resistance.

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: What is the heat treatment process of cemented carbide?: To put it plainly, that is, hardening of cemented carbide, that is, heating to a certain temperature, insulation for a certain period of time, and then suddenly into the inert gas, so that it suddenly cooling.. The same as steel quenching. After quenching generally tempered, to eliminate the stress produced by quenching, it is mainly to change the bonding phase components, that is, the organizational structure, improve the strength of cemented carbide, hardness and comprehensive performance

Q: How to solve the severe wear of the flank of the carbide blade during machining?: 2. Contact the company or log on to the company's website for communication.Carbide inserts are made of hard alloy, an alloy made from refractory metals, hard compounds, and bonded metals by powder metallurgy.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.

Q: How are cemented carbides sintered?: 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. Then, when the mixture is granulated and pressed and heated to a point near the bonding metal (1300~1500 DEG C), the eutectic alloy is formed by the hardening and bonding of the metal.
