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:Classification of Cemented Carbides
1 tungsten cobalt carbide2, tungsten, titanium and cobalt carbide3, tungsten, titanium, tantalum (niobium) carbide
Q:What material is that ultrafine cemented carbide?
The main component of cemented carbide is tungsten carbide, so also known as tungsten steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness can reach HRB89 to 95Tungsten steel production process is as follows: the powder is pressed into a blank, and then into the furnace heated to a certain temperature (sintering temperature), and keep a certain time (time), and then cooled down to obtain the required properties of tungsten materials.The characteristics of ultrafine cemented carbide is the main component of WC, compared to the hard phase and general hard alloy, the hard phase particles are very fine (average grain size less than 1um), so you can get a higher than the general hard alloy of the same hardness strength (toughness), edge grinding can be sharper and better wear resistance.
Q:Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?
Now on the market scrap carbide blade about 100 yuan / kg, depending on the alloy composition, trading area and fixed.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.
Q:Carbide drills and cobalt high speed steel bit, which is good? What's the difference between these two materials?
This is the first use, each one has its own merits, hard alloy with high hardness, suitable for high speed drilling and high hardness materials, and high cobalt high speed steel has good toughness, suitable for low hardness material, suitable for drilling slower machine.
Q:General carbide and high-speed steel blade cutting speed? (about the range is OK.)
Carbide wire feed rate F0 per revolution. 08-0. 2, high-speed steel: F0. 03-F0. 1, see what processing materials, machine tools, steel and sex
Q:How much does carbide WC contain?
For example, YT15, which represents average TiC=15%, is tungsten carbide cobalt carbide with the remainder of tungsten carbide and cobalt contentTungsten, titanium, tantalum (niobium) carbidesIs the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. The hard alloy and hard alloy general or universal hard alloy.
Q:Does the hard alloy belong to the composite material?
1. carbide is based on tungsten carbide as matrix, cobalt as binder, according to the needs of the titanium, tantalum, niobium and other metals to obtain the "alloy" material.2. because this alloy is relatively hard, so called him "carbide", people often used to do machining tools.3., from the definition of "composite material", "alloy" belongs to "composite material"". Therefore, cemented carbide belongs to composite material.
Q:Can hard alloy be used in food?
Used for processing food should not be possible, the composition of tungsten carbide.
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:The requirement of machining thread holes on carbide is higher
The shrinkage coefficient must be taken into account, but the technical requirement is quite high and the molding is difficultIn the processing of hard alloy threads, if high precision, small hole, can be used in EDM processing, now EDM with C axis, don't work fixture, the thread can play any pitch, as long as the processing thread electrode is.
