Product Description

Ferro Chrome

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.

Chrome is mainly 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 chrome is applied to making stainless steel, acid-resistant steel and heat resistant steel.

Q:How to polish the rough surface of cemented carbide?
Polish the surface of the cemented carbide surface by using diamond abrasive paste. When polishing, can not cut short, should be in accordance with the first rough grinding paste polishing, and then use fine grinding paste polishing process, and can not be directly polished with fine abrasive paste. Otherwise, the surface of the material will leave a wavy corrugation, which will be difficult to be polished with fine abrasive. In addition, the grinding efficiency of fine grinding paste is much lower than that of coarse paste.
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:What type of emery grinding machine is 3000/min for grinding carbide turning tools (e.g., YG8.YS8.YT15.YW1, etc.)?
Green silicon carbide grinding wheel, not sure. You'll have to look at the real map. Some resin grinding wheels are also green.
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:High end markets for cemented carbides
In 2007, 16 thousand and 500 tons of cemented carbide produced in our country, 4500 tons were used in cutting tool production, and the quantity was quite similar to that in japan. But the value of the tool is only 800 million U. S. dollars, far less than Japan's 2 billion 500 million U. S. dollars, which fully shows that the overall production level of domestic carbide efficient tool is still quite a gap with foreign countries. Therefore, in the domestic enterprises can not meet the market demand under the premise of the manufacturing industry will have to rely on a large number of imports to solve. Data show that the main foreign market in China's high-end cutter sales growth rate of 30%, has exceeded the average annual growth rate of domestic knives.
Q:Where can I buy more than 94 hardness carbide cutter head, welding, the best address in detail, thank you!
It's no problem to weld cemented carbide. Please call me when you need it
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: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:Chengdu which has carbide scrap acquisition point?
Bars of 75000 yuan / kg (Fu Xujian) Zhejiang Zhoushan self-employed waste tungsten 150-200 yuan / kg, Hebei Hengshui Gucheng County Sindh rare metals tungsten tailings 100-300 yuan / ton Guangzhou lechran gold bars 1200 yuan / kg, Zhengzhou Zhengzhou Hongsen tin small PCB tungsten steel drill 160-190 yuan / kg in Zhejiang Taizhou
Q:Carbide cutters can work on materials of higher hardness
This problem is too general, and hard alloy processing range is very wide (it also has many kinds of material), from soft aluminum alloy, copper alloy to HRC60-70 degree of mold can process, the key is to see what you want to process materials
