ferromanganese

There are three kinds of ferromanganese according to its different carbon content: low carbon FeMn, middle carbon FeMn, high carbon FeMn. And there are two different types of high carbon FeMn according to their different chemical composition: electric furnace FeMn and blast furnace FeMn.

Application: deoxidizer, alloying agent, desulfurizer.

High Carbon Femn For Steelmaking

Q: What is the resistivity of the yg13 cemented carbide?: Two, production processProportioning, mixing, crushing, drying, fully add sifted molding agent, then drying and sieving to prepare a mixture, pressing, mixing and granulating (Germany imported vacuum pressure sintering furnace), low pressure sintering and sintering the blank test after (nondestructive ultrasonic inspection), blank size accuracy test.

Q: Welding hard alloy cutter, hard alloy cutter, high speed steel, ceramic knife head head are what are the advantages and shortcomings?: The advantages of carbide drill can drill more hard material, the disadvantage is to be good grinding, grinding is not good, easy to break the edge, two main cutting edge height and angle equivalent, it is best to use the grinding machine.

Q: HSS clip can clamp the hard alloy saw it: The cutter head is mounted on the cutter body and the grinding cutter is called an internal grinding type; the cutter head is individually worn on the fixture and is called external grinding type.Indexable(indexable tools): this kind of structure has been widely used in face milling cutters, end mills and three edged cutters.Product classificationTooth milling cutterA narrow blade is sharpened on the flank to form the back angle, and the cutting angle is reasonable, and the service life is higher. Sharp cutter tooth back straight, curve and line 3 forms.

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 are the cemented carbide coatings?: The hard alloy coating is used to form high hardness wear-resistant coating on the surface of metal, Beijing Naimo company according to the composition of the alloy is divided into:1.jp8000 spraying tungsten carbide coating2. nickel tungsten alloy coating3. cobalt tungsten alloy coating

Q: What is the consciousness of YT in YT cemented carbide?: YT carbide hard alloy has relatively high hardness, but poor toughness, poor impact resistance. It is suitable for processing plastic material used to machining without quenching medium and low carbon steel, alloy steel and so on.

Q: What is the hardness of the carbide thread?: 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.

Q: I've seen a lot of classification, what tools, hardware, machinery, machinery, metallurgy, minerals, etc.,But I always don't know what the hard alloy belongs to. What can I do for you?: Modern ultra hard alloys are produced by sintering of carbides of tungsten carbide and some other elements. It is the hard metal (tungsten, tantalum, titanium, molybdenum, etc.) carbide carbide particles, with one or several iron elements (cobalt, nickel or iron) powder mixed, pressed molding, and then made by sintering.

Q: Import all carbide drill bit, mainly those brands: Cobalt collar, YG, Santak, Kenna and so on, YG cost-effective. Used in the high efficiency, high precision, difficult to processing materials, with the overall hard alloy, with cold or cold.

Q: What are hard alloys? Which ones are they? How often are they chosen?: It is based on one or several carbides (TiC and WC) as the hardening phase, with carbon steel or alloy steel (such as high-speed steel, chrome molybdenum steel) powder as binder, powder metallurgy materials through proportioning, mixing, pressing and sintering. After annealing, it can be machined. After quenching and tempering, it has the same hardness and high wear resistance as the hard alloy. It can also be forged and welded, and has the characteristics of heat resistance, corrosion resistance and oxidation resistance. The utility model is suitable for manufacturing various tools with complicated shapes, such as twist drills, milling cutters, etc., and can also manufacture moulds and wear-resistant parts which work at higher temperature.
