Product Description
Ferro Alumium manganese alloys  

AlMnFe alloy is used as a deoxidizer in steelmaking, which can improve inclusion form and reduce the content of gas element  in molten steel.It can replace general alloy and pure aluminum for the final deoxidization in the process of steelmaking.
(1) Deoxidizing with Al-Mn-Fe can improve the quality of steel products.
(2) Deoxidizing with Al-Mn-Fe can make Al recovery stable, reduce the aluminum consumption and improve the rate of refining.
(3) Simplify the process of deoxidizing, be easy to operate and reduce the labor intensity.
(4) Have remarkable economic and social benefits by deoxidizing with Al-Mn-Fe.

Q:Can hard alloy be made into barrel?
No, hard alloy too hard too fragile, not processed, there should be a rifle barrel, it is difficult to machining.
Q:The requirement of machining thread holes on carbide is higher
If the precision of the thread is not high enough, it can be produced by pressing.
Q:Hard alloy and cast iron join together, what glue is good?
Carbide and cast iron are preferred welding methods. Instead of bonding.Can use oxygen acetylene flame gas welding (high combustion temperature, acetylene to hard alloy is heated to a suitable temperature, can be used instead of propane gas), first to the hard alloy is heated to (dark observation) small red, give heating. Were mixed with borax and boric acid as flux, HS201 copper wire dip brazing flux hard alloy and cast iron welding.Bonding shall be considered without welding conditions.The cast iron and carbide surface is polished with fine sandpaper. A soft cloth for wiping dirt and grinding residue. 1:1 AB glue evenly, smear on the contact surface of cast iron and hard alloy. Slightly pressurized. Set aside for 12 hours.
Q:Why is Zhuzhou cemented carbide plant called (601) 80??
Construction 601 is for military services, and now the city has changed. Now there are many military factories are code names, only know its code name, I do not know what it is to do.
Q:Vacuum sintering of cemented carbide vacuum.
This is not necessarily, the hard alloy sintering infiltration decarburization mainly in wet grinding your ingredients and carbon sintering process control, vacuum furnace gas in order to prevent the reaction of pure, alloy with oxygen in the air, infiltration and decarburization products have no direct relationship, of course if it is caused by the leakage of vacuum sintering furnace can not meet the requirements, will lead to the direction of decarburization alloy.
Q:Can hard alloy be used in food?
The processing link is possible. Food segment will not be able to ah!
Q:What is the hardness of cemented carbide?
Different grades, different hardness, usually (86 ~ 93HRA, equivalent to 69 ~ 81HRC);
Q:What kind of clamp blade should be used for hard alloy?
Hard alloy tools are used for turning cemented carbides. Now the general superhard materials are PCD (polycrystalline diamond) and PCBN (poly cubic boron nitride)However, because carbide contains more carbon elements, PCD is easy to produce chemical dissolution (carbon affinity) during processing, so the PCBN blade should be considered.
Q:Several hard alloy cutter lathe with?
2 kinds! They are clamp type and welding type.
Q:What is the specific gravity of cemented carbide?
The carbon content of WC theory is 6.128% (atom 50%). When the carbon content of WC is greater than the theoretical carbon content, the free carbon (WC+C) appears in WC. The existence of free carbon leads to the growth of WC grain around it, resulting in uneven grain of cemented carbide. General requirements of tungsten carbide compound carbon high (more than 6.07%), free carbon (less than 0.05%), the total carbon depends on hard alloy production process and use scope.Under normal circumstances, the total WC carbon content in the vacuum sintering process of the paraffin process is mainly determined by the combined oxygen content in the block prior to sintering. An oxygen content should be increased by 0.75 parts of carbon, that is, WC total carbon, =6.13%+ oxygen content,% * 0.75 (assuming the sintering furnace is neutral atmosphere, in fact, most of the vacuum furnace is carburizing atmosphere, and the total carbon content of WC is less than the calculated value).At present, China's total carbon content of WC is roughly divided into three kinds: paraffin process, vacuum sintering, the total carbon content of WC is about 6.18 + 0.03% (free carbon will increase). The total carbon content of WC for hydrogen sintering of paraffin process is 6.13 + 0.03%. For rubber process, WC total carbon =5.90 + 0.03% is used for hydrogen sintering. The process is sometimes interleaved, so the determination of WC total carbon should be based on specific circumstances.
