1 Application
Ferromanganese a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace. The oxides undergo carbothermal reduction in the furnaces, producing the ferromanganese. Ferromanganese is used as a deoxidizer for steel.

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 the coefficient of thermal expansion of cemented carbides?
- Carbide is also divided into many grades, so the coefficient of thermal expansion is not exactly the same.
- Q:Which prawns know of what is called red hard alloy.
- This form of exercise is intense, and the more objects or systems formed by these microscopic particles become hotter. As the temperature rises, the object begins to emit visible light, first of all, the longer red part, which turns from dark red to orange red.
- Q:What kinds of carbide knives do you have? Write out its main functions and uses.
- (3) tungsten tantalum cobalt (WC+TaC+Co) cemented carbide (YA);The addition of TaC (NbC) on the basis of YG cemented carbide improves the hardness and strength, thermal shock resistance and wear resistance at room temperature, high temperature, and can be used to process Cast Iron and stainless steel.(4) tungsten, titanium, tantalum, cobalt (WC+TiC+TaC+Co) and hard alloy (YW), such as W1, W2 and so on.On the basis of YT cemented carbide, TaC (NbC) is added to improve the flexural strength, impact toughness, high temperature hardness, oxygen resistance and wear resistance. Both can process steel, but also the processing of cast iron and non-ferrous metals. Therefore, it is often called universal cemented carbide (also known as universal cemented carbide). At present, mainly used for processing heat-resistant steel, high manganese steel, stainless steel and other difficult materials.
- Q:belong to raw material? After buying instockroom directly under the workshop to account for 5The company is small, no warehouse, do not fill in a single storage, the parts purchased directly to use, how to do?It's so complicated. Is there a simple way to do it?
- Bolts are standard partsDiverter and mutual inductor belong to instrument classGears and chains belong to mechanical partsTo have a task list of tasks, facilitate the cost accounting of this task.Establish simple running account, operator, operator's signature and use.
- Q:What are the parameters of the wear resistance of cemented carbides in addition to their hardness?
- The bending strength of YG20 can reach 2500, which is suitable for making stamping dies. The bending strength of YG15 and JK13 can reach 2550, and the bending strength of JK15 can reach 2600, but the wear resistance is lower. The flexural strength of JK1 is 2500, and it has good wear resistance.
- Q:What is the difference between tungsten cobalt alloy and YG8 and YG6 series cemented carbide?
- YG6, YG6X, YG8, YG8C, YG11C, and so on,YG6 hardness and wear resistance are slightly higher than that of YG8, but strength and toughness are not as good as YG8
- Q:What are the three types of commonly used cemented carbides?
- ISO divides cemented carbide into 3 classes: P, K and M.P class (equivalent to China's YT class) carbide by WC, TiC, and Co composition, also known as tungsten titanium cobalt carbide. This kind of alloy is mainly used for processing steel materials.
- Q:Carbon steel valves in Baidu LibraryThe temperature can reach 425 degrees, is not without welding carbide seal, who has no detailed material ah?,
- This 425 DEG C is the limit temperature of ASTM A216: -30 DEG C - +425 DEG CBut if the sealing surface of rice now is PTFE, it can be as high as +80 degrees centigrade. If the PTFE material is good, it can reach +150 centigradeTherefore, the body material is carbon steel, only that the valve body of the temperature range of this materialLook at the inside of the valve,For example, cryogenic carbon steel in LCB, ASTM, A325 can reach -46 degrees --+340 degrees centigradeHowever, if the sealing surface of your body is the sealing surface of plain carbon steel, the temperature range of this carbon steel valve is only the temperature range of the ordinary carbon steelIf you say that now is the carbon steel valves used in the sealing surface of the safety valve, you must need welding hard alloy (STL or D series, etc.) should have strong hardness of hard alloy after treatment, impact resistance.Depends on your flow channel medium, if it is high temperature, it is best to use 316, and so onThe use of valves is a combination of considerations
- 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:How to distinguish the authenticity of Zhuzhou diamond brand cemented carbide blade?
- Zhuzhou diamond brand cemented carbide blade is the first brand in our country. We can distinguish its authenticity from the following aspectsVisual package: it is packed in plastic box, the upper and lower cover are transparent plastic, and the bottom box is blueNormative labels: according to the ISO standard, lists the recommended types of processing materials, bar code identification, marked "diamond brand" trademark and "China well-known trademark" and enterprise logoType anti-counterfeit: each piece of hard alloy welding machine, clamping blade convex superscript "ZCCT" logo, direct press formingSealing anti-counterfeiting: labels and sealing paste affixed to the interface of the packaging box, one-time paste, can not be pasted after tearingZhuzhou Jing Jing carbide sales Co., Ltd.
