Ferro Manganese Introduction:

1. Ferro Manganese is an alloy of Iron and manganese, with manganese between 65.0%~90.0%, as deoxidizer and alloying element additive. Divided into furnace ferromanganese and blast furnace ferromanganese.

2. Main categories: high carbon ferromanganese (carbon 7%), medium carbon ferromanganese
(carbon 1.0~1.5%), low carbon ferromanganese (0.5% carbon), metal manganese, Spiegel, Silicon-manganese alloy.

3. International general standard for carbon ferromanganese containing mananese with 75 ~ 80%. To adapt to theconditions of low grade raw ore, China provides manganese lower grades (furnace ferromanganese
manganese containing more than 65%, blast furnace ferromanganese manganese containing more than 50%).

Application

1. Mainly used as alloy additives and deoxidizer in steelmaking.

2. Used as alloy agent ,widely applied to be widely applied to alloy steel, such as structural steel, tool steel, stainless and
heat-resistant steel and abrasion-resistant steel.

3. It also has the performance that it can desulfurize and decrease the harmfulness of sulfur. So when we make steel and cast iron, we always need certain account of manganese.

Q:What is steel bonded carbide? What are its characteristics?
Good physical and mechanical properties of steel bonded carbide in a hardened state has very high Hardness. Because it contains a lot of dispersed high hardness of hard phase, the wear resistance can be close to the high cobalt hard alloy. Compared with high alloy die steel, has high elastic modulus, wear resistance, compressive strength and flexural strength. Compared with the hard alloy, with good toughness. It has good chemical stability and self lubrication resistance, low friction coefficient and excellent.
Q:What materials are ZK20 cemented carbides processed?
ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic
Q:There are three kinds of cemented carbides, of which tungsten, cobalt and titanium are brittle cemented carbides?
Tungsten titanium cobalt carbide a tungsten titanium cobalt carbide consisting of WC%26mdash, TiC, WC and bonded cobalt metal or a multiphase hard alloy consisting of only WC%26mdash, TiC solid solution and cobalt. Cobalt content of alloy 4% ~ 10%, containing TiC5% ~ 30%, margin of WC, mainly used for cutting steel.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. There is no such term as brittle cemented carbide.
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 does WC refer to in cemented carbides?
Tungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobalt.The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.For example, YT15, which represents average TiC=15%, is tungsten carbide cobalt carbide with the remainder of tungsten carbide and cobalt content.Tungsten, titanium, tantalum (niobium) carbidesIs the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.
Q:What kind of cemented carbide is used for processing HRC40 degrees stainless steel?
This kind of hardness stainless steel is martensite, hardness is high, use tungsten cobalt class (do not use tungsten, cobalt, titanium, this is attention 1), and carbide containing Ta. Such as: YA6, YH1, YW3, etc.. This kind of steel is of high hardness, small feed rate, lower cutting speed, greater cutting depth, and avoiding the work hardening of the surface leather and the front working procedure (Notice 2). Machine tools. The steel of the tool is better. The coolant selects viscous and chlorine - containing cooling liquid with good adhesion and cooling performance. (Note 3)
Q:Carbide drills and high-speed steel drills, which are suitable for processing stainless steel 10?
Carbide drills are suitable for high speed steel
Q:What kinds of carbide knives do you have? Write out its main functions and uses.
(2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT), such as YT5, YT15, YT30 and so on.Because of the hardness and melting point of TiC is higher than WC, so compared with YG, its hardness, wear resistance, red hardness increase, bonding temperature is high, antioxidant ability is strong, and in high temperature will produce TiO 2, can reduce bonding. But the thermal conductivity is poor and the bending strength is low, so it is suitable for the processing of steel and other tough materials.
Q:Carbide blade domestic that tricky point?
Chengdu, Dalian Fuji, Chengdu Sentai eng, Qianmu NC tool and so on quantity.
Q:What is hard alloy grinding?
Its scope of application and the artificial diamond plays a complementary role. Cubic boron nitride wheel grinding of steel parts the efficiency ratio of corundum wheel to nearly a hundred times, five times higher than the diamond grinding wheel, but less than the diamond grinding of brittle materials.The diamond grinding wheel than boron carbide, silicon carbide, corundum and other general grinding blade grain made of sharp corner, small abrasion, long service life, high productivity, good processing quality, but the price is expensive, is suitable for the grinding of hard alloy, ceramic, semiconductor and other high hardness brittle hard processing material
