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:Dalian enterprises now need 16.3 and 19.3 mm in diameter, the whole cold hard alloy bit, where can I find buyers? Leave a contact: Xi'an Jie Electrical Machinery Co., Ltd. internal cooling alloy drill, factory direct sales

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?: YT14 Feiyan containing titanium, titanium with high oxygen affinity, if high oxygen content and sintering process not reasonable, high temperature gas production could not be drained to form holes, you see the sintering process is reasonable, the presence of liquid phase before the vacuum degree is not high enough. In addition, such as incomplete degassing holes in the product, the edge is more.

Q:There are three kinds of cemented carbides, of which tungsten, cobalt and titanium are brittle cemented carbides?: [classification of cemented carbide] ISO carbide carbide cutting into 3 categories: P, K and M.1, P class (equivalent to China's YT class) cemented 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. Common brands are YT5 (mass fraction of TiC is 5%), YT15 (mass fraction of TiC is 15%), with the mass fraction of TiC increased, the mass fraction of cobalt decreased, hardness and wear resistance increased, bending strength decreased. This kind of hard alloy is not suitable for processing stainless steel and titanium alloy.2, K class (equivalent to China's YG class), carbide composed of WC and Co, also known as tungsten cobalt carbide. These alloys are mainly used to process cast iron, nonferrous metals and their alloys. The common grades are TG6 (cobalt mass fraction 6%) and YG8 (cobalt mass fraction 8%). As the mass fraction of cobalt increases, the hardness and wear resistance decrease, and the flexural strength and toughness increase.3, M class (equivalent to China's YW class), carbide is based on WC, TiC, Co, and then added TaC (or NbC) and into. After the addition of TaC (or NbC), the comprehensive properties of cemented carbide were improved. Such cemented carbide can be used for both cast iron and non-ferrous metals, as well as for steel and for high temperature machining

Q:What are the types and specifications of carbide cutters?: The main components are tungsten carbide, titanium carbide (TiC) and cobaltThe grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.For example, YT15 is a tungsten titanium cobalt carbide that represents an average WTi = 15% and the remainder is tungsten carbide and cobalt content

Q:Carbide cutting insert: These brand knives are usually Zhuzhou diamond brand and Zigong the Great Wall brand. Other brands are also located in these areas.

Q:One can write on the hard alloy on the pencil, what's the name ah, who knows.: Electric spark marking pen. 230 of the price is kind. The power of cemented carbide should be chosen a little larger.

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:Hello, what's your company? What do you do with carbide? Thank you in advance: Pro, what do you mean by that question? We are the hard alloy recycling companies, focus on hard alloy recovery, Qingdao cemented carbide business network, with the recovery of hard alloy scrap, hard alloy die, tungsten steel scrap recycling

Q:What brand of carbide is used in woodworking tools?: Carbide YS2T: is used for low speed roughing and milling of heat resistant alloys and semi finishing of titanium alloys, stainless steels, and low alloy steels. Carbide YL10.2: has high flexural strength and good wear resistance, used in low speed rough car and milling heat-resistant alloy, titanium alloy, also can be processed glass fiber reinforced plastic, making PCB micro drilling and so on. YG3/YG6: is suitable for hard alloy cast iron, nonferrous metals and their alloys and non metallic materials during continuous cutting fine cars, semi refined car, suitable for small section iron fine car, and can be used for the coarse thread, steel, nonferrous metals, wet lubrication tensile alloy wire and non metal wire drilling etc..

Q:How to tell what is hard alloy and what is high speed steel?: Experiment with a magnet, carbide is not sucked, high-speed steel can suck.Hardness can be tested by marking plates or glass.
