Q:What are the carbide inserts on the turning tool welded to the handle?
The first copper burned in the post, and then the borax fell on the top, then put on top of the alloy blade, borax fell on the alloy blade above the flame cutting with money. Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly. Let him cool naturally,
Q:What kind of carbide alloy is used in stainless steel processing?
The hardness of stainless steel is martensite, high hardness, using tungsten cobalt (do not use tungsten cobalt titanium, this is the 1 note) and Ta containing hard alloy.
Q:What are the three types of commonly used cemented carbides?
ISO divides cemented carbide into 3 classes: P, K and M.P class (equivalent to China's YT class) carbide by WC, TiC, and Co composition, also known as tungsten titanium cobalt carbide. This kind of alloy is mainly used for processing steel materials.
Q:Method for assembling hard alloy cold heading die
Technological requirements for hole processing of cemented carbide die:1, carbide mold hole processing, selection, processing methods: according to the requirements of the drawings, select the electrical processing methods.2, select electrode material: according to the processing requirements, determine the processing methods and processing equipment to determine the electrode material.3. Design electrode: Design electrode according to clearance, shape and effective length of blade.4, processing electrode: generally use shaping grinding or square planer processing.5 、 clamping electrode.6, be processed carbide mold preparation.7. Calibration electrode.8 、 carbide mould clamping and positioning.9. Adjust the upper and lower positions of the spindle head.10, processing preparation.11, boot processing.12, regulation switching and intermediate inspection.13, carbide mold inspection: carbide mold after processing, should be carefully checked according to drawings, whether it meets the requirements of the drawings
Q:Buy whole cold carbide drills
Xi'an Jie Electrical Machinery Co., Ltd. internal cooling alloy drill, factory direct sales
Q:What is the heat treatment process of cemented carbide?
The common heat treatment process of steel bonded carbide is spheroidizing annealing, quenching and tempering.1, spheroidizing annealing die steel bonded carbide matrix is steel, as the alloy tool steel, need to be spheroidizing annealing treatment, can machine processing. The process of spheroidizing degradation is: heating 850~890 DEG C, holding 4h, and cooling the furnace to about 730 DEG C, holding 6h, the furnace is cold, and the air cooled below 500 degrees centigrade,2, the purpose is to make the quenching matrix transforms into martensite, obtain high mechanical properties, due to poor thermal conductivity, preheating, hard steel bonded carbide in carbide phase of austenite grain growth to deter, and the dissolution of carbide in the matrix alloy, iron and hinder the diffusion of carbon atoms, of austenite the grain growth plays an inhibitory effect, so the steel bonded hard alloy quenching overheating less than alloy tool steel, quenching temperature can be higher, the time may be longer, usually for WC type steel bonded hard alloy, quenching temperature of 1020~1050; for TiC type steel bonded hard alloy, quenching temperature is 950~1000 DEG C; G type steel bonded cemented carbide phase with high speed steel, quenching temperature of 1200~1280.3, steel bonded hard alloy die after quenching tempering should be timely, especially the large die should be timely, in order to eliminate quenching stress, prevent mold cracking, while tempering can adjust the organization to obtain the mechanical properties required, tempering temperature often take 180~200 C, 2h insulation, high toughness, high temperature tempering can be used as 500~650 C, but the need to avoid the brittle temperature zone at 250~350 DEG C, high temperature tempering, the carbide precipitation and residual austenite transformation, there will be two hardening, but high temperature tempering will cause precipitation of lead carbide link impact toughness decreases.
Q:What are the contents of cemented carbide production test 20
Fluorescence detection: fluorescence detectorScanning electron microscope: SEM scanning electron microscopeXRD: XRD testElectron microscopy: TEM projection electron microscopyMy school student, brother, I speak not all, you should all do so, detection cost is not expensive, but the equipment to buy it, not tens of millions of nabuxialai, and equipment is not the same.
Q:What is the tungsten alloy blade, what is the difference with the hard alloy blade? What is it for?
Tungsten alloy blade is a kind of hard alloy, metal processing used in the workpiece.
Q:What are the differences between the two grades of carbide, YT15 and YT5?
YT5 is often used for roughing or machining, impact cutting, and YT15 is usually semi finishing and finishing.
Q:What are the types and types of carbide inserts?
Your question is really not a simple answer can be got, to see you on what to divide, the blade types according to use classification, can also according to the material classification, and so on, I suggest you go to the official website of Zhuzhou China tungsten alloy has a hard alloy technology knowledge base to see. There's an introduction.
