Phosphorus iron honeycomb appearance, phosphorus is 20-26%, 0.1 6% of intergrowth compounds containing silicon. Phosphorus in the steel industry as an alloying agent, iron alloy additives for use in the metallurgical and deoxidizer.

In general steel products, phosphorus is harmful ingredients, but in some special products, the addition of phosphorus, can improve the performance of certain aspects of steel. Phosphorus iron is widely used in roll, auto cylinder liner, engine roller and large castings in order to increase mechanical parts corrosion resistance and abrasion resistance

Q: suitable for processing the whole alloy drilling, milling, reaming and other cutting tools. This alloy tungsten, cobalt content, how many of you?: Just found the carbide under YK15, its cobalt content in 10%.According to its brand, YK15 should be used to process cast iron, so the main ingredient should be WC+Co.So its WC component should be in 89-90% (just for inference, for reference only)Based on the molar mass of WC, the mass fraction of the W content is deduced

Q: In addition, the same furnace products out, the standard sample bar is qualified, no hole, but YT14 blade has more holes, why is that ah?: Too many factors, but according to the shape, size, number and distribution state can be roughly determined what caused by links.

Q: Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?: Now on the market scrap carbide blade about 100 yuan / kg, depending on the alloy composition, trading area and fixed.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.

Q: What are the cemented carbides?: Tungsten cobalt carbideWC cutterThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt.For example, YG8, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.

Q: What does carbide wet grinding mean?: 2. the number of grinding bodiesThe number of grinding bodies is usually described by the fill factor. The filling factor is equal to the ratio of the volume of the grinding ball to the volume of the cartridge.It is generally believed that the ball mill with carbide ball and carbide lining can guarantee the minimum coefficient of filling of rolling grinding by 0.4. When the filling coefficient exceeds 0.5, the ball near the center of rotation is blocked by the ball because of the small radius of rotation, so it is in a relatively static state with the grinding cylinder and reduces the grinding efficiency. Moreover, with the increase of filling factor, the grinding efficiency decreases regularly

Q: Is there any pollution in the production of cemented carbide?: The main pollutants in the production of cemented carbide are dust, waste residue and waste water, and the biggest influence on the environment is soot. According to regulations, waste gas can be divided into two categories: particulate matter, exhaust gas and gaseous pollutants. The exhaust gas of ferroalloy plant comes from ore smelting furnace, refining electric furnace, roasting rotary kiln, multi layer mechanical baking furnace and aluminum metal smelting furnace. Ferroalloy plant exhaust emissions, dust concentration is high, 90% of exhaust gas is silicon dioxide, but also contains chlorine, nitrogen oxides, carbon monoxide, sulfur dioxide and so on. Waste residue and waste water are the most serious pollution of chromium compounds, and there are also pollution of nickel compounds.The State Economic and Trade Commission, the State Environmental Protection Administration and other departments also jointly issued "on accelerating the restructuring of China's ferroalloy industry views" (in the economic and trade industry [1999]633), from 1999 to 2005, to stop the new types of ferroalloy electric furnace (kiln) and blast furnace.

Q: How much does carbide WC contain?: For example, YG8, tungsten carbide cobalt alloy that represents an average WCo=8% and the rest of tungsten carbideTungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobaltThe grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.

Q: What are the fields of nano WC Cemented Carbides applied?: (2) electronic industry. The development trend of electronic products is miniaturization, integration and precision. The integrated circuit board is made of epoxy resin, glass fiber or glass fiber reinforced plastic. This requires micro drill has high hardness and wear resistance; while the drill diameter is very small (generally 0.2 ~ 0.3mm, and 0.05mm), easy to break, also called bit has high strength and toughness, and need to correct drilling hole position accuracy, and the drill bit has high stiffness (elastic modulus). These conflicting requirements. The common hard alloy and fine grain carbide drills are difficult to meet these requirements, only the use of nano grain carbide grain size of less than 0.5 m. And as the dot printing needle, its diameter is only 0.2-0.35mm; multi frame processing integrated circuit lead by the progressive die, punch thickness less than 0.2mm, the error is only 0.002mm; in addition to the printed circuit board with wire cutting head disc cutter, and the precision of the small die, all require the use of Nanocrystalline WC cemented carbide in order to achieve its function to produce alloy.

Q: Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!: Hard alloy is too high and can not be polished by ordinary metallographic sand paper. It should be put on the machine tool by diamond grinding wheel, and the cost is also very cheapReally manual grinding, then you can add grinding cream to try, but the efficiency is very low

Q: What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?: 1.p stands for ferrous metals suitable for working long cuts.2.p30 is suitable for working steel, cast steel, long cut malleable iron. Suitable for general rough machining.
