Product Description:

Good Quality Ferro-Manganese for Sale Chinese Supplier


Usage of Ferro manganese

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.



It used the high quality anthracite as raw materials through high temperature calcined at over 2000 by the DC electric calciner with results in eliminating the moisture and volatile matter from anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation. It has good characteristics with low ash, low resistvity, low sulphur, high carbon and high density. It is the best material for high quality carbon products.

Q:What type and hardness of grinding wheel 20 for general carbide turning tools?
Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. Now, the cutting speed of new carbide tools is several times that of carbon 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.
Q:What is the base material of carbide saw blade?
Base material of carbide saw blade1., 65Mn spring steel, good elasticity and plasticity, material economy, heat treatment, hardenability, and its heating temperature is low, easy to deformation, can be used for cutting requirements of the blade is not high.2. carbon tool steel with high carbon content, high thermal conductivity, but by 200 degrees -250 degrees Celsius temperature, its hardness and wear resistance decreased rapidly, heat treatment deformation, hardenability, tempering time is long, easy to crack. Manufacture economical materials for cutting tools, such as T8A, T10A, T12A and so on. 3. alloy tool steel, compared with carbon tool steel, has good heat resistance, good wear resistance, good treatment performance, heat-resistant deformation temperature of 300 degrees -400 degrees, suitable for manufacturing high-grade alloy circular saw blade.4. high speed tool steel has good hardenability, hardness and rigidity, less heat distortion, ultra high strength steel, thermoplastic stability, suitable for manufacturing high-grade ultra-thin saw blade.
Q:What are the meanings of cemented carbide codes, such as YS30, YN10, YW?
Y is the abbreviation of "hard". The letter behind is the abbreviation of metal material, such as "L" is "aluminum", "YL" is "hard aluminum". The number should be related to the alloy composition.
Q:What does carbide K15-K20 refer to?
generally used to process Cast Iron and non-ferrous metals15 represents its abrasion resistance or impact resistance,The smaller the value, the harder the hardness of the table is and the less resistant it is to the impact;
Q:The use of cemented carbides YG and YT
Three, need to point out is: YG, YT, YW each alloy has different models, each model has different applicable range, the above refers to the comprehensive analysis.
Q:Carbide coated drill bit will reduce the service life after grinding, how to avoid?
1. carbide drills are generally worn in the back. Then it has little influence on service life.2., the high strength of the workpiece material, easy to cause the front of the drill (spiral groove) wear, bit life impact.3. the wear of drill bit belt has the most serious influence on drill bit life.4. so, when using the drill, pay attention to it:(1) the drill should be kept as small as possible at the top of the drill bit.(2) the spindle of machine tool has enough rigidity and precision.(3) the drill shall be replaced and sharpened when used.5., the drill can be re coated after grinding, pre treatment should be done before coating. To increase the coating effect.
Q:Compare the advantages and disadvantages of high speed steel and cemented carbide
High speed steel, high carbon steel, can be divided according to chemical composition of tungsten and molybdenum in steel, cutting performance is divided into high performance of ordinary high speed steel, high speed steel. Through strengthening heat treatment of high speed steel.
Q:It is hard alloy steel
Tungsten steel and hard alloy: tungsten carbide is the difference is a. Tungsten is raw material for smelting ferrotungsten adding steelmaking process in molten steel for tungsten and also called high speed steel or tool steel, the tungsten content in 15-25%; and the hard alloy is used in powder metallurgy process of tungsten carbide and cobalt as the main body or other binding metal sintering, the tungsten content in general in more than 80%. Simply put, all the hardness go more than HRC65 things, as long as the alloy can be called carbide.
Q:What kind of industry can use carbide?
The metal processing tool, electronic industry to do the drill bits, the medical industry mainly do the drill. Carbide tools have been used in various industries, known as industrial teeth.
Q:What is carbide material P30, please?
ISO (International Organization for Standardization) will be divided into carbide alloy P, M, K three categories, P class equivalent to China's YT class, the main ingredient is WC-TiC-Co;In order to be processed in different cutting conditions of material grade, in the P class with 01-50 number between that from the highest hardness to a series of alloys for maximum toughness between P30, roughly equivalent to the YT5 of our country;This kind of cemented carbide has the highest strength and best impact resistance in YT (P), but it has poor wear resistance. It is suitable for intermittent roughing of general carbon steel and alloy steel.
