Atomised Ferro Silicon 15 is a specialised powder product formed by melting FeSi75 with scrap and casting into a high pressure water jet. Particle size is typically between 212 microns and 20 microns. The principal properties of FeSi15%

are magnetism, corrosion resistance and density.

Atomised Ferro Silicon 15% is mixed in water to create a dense medium and finds uses in the mining and scrap processing industries. Dense medium separation is a gravity separation technique which creates a medium with a specific density.

This medium allows lights to float and heavies to sink, thus permitting separation due to density. The process typically

separates aluminium, magnesium and mixed heavy metals such as copper alloys, thereby increasing overall scrap

metal recycling rates. After sizing, the mixed feed is screened and then sent to a drum containing magnetite media

which removes the lower density waste (rubber, plastic, etc) and light metals such as magnesium alloys.


The heavy concentrated scrap is then directed to a second drum containing FeSi media which separates the aluminium

from other metals. These two media, namely Magnetite and FeSi, create different media densities and can be adjusted,

within certain limits.

Atomised Ferro Silicon 15% is usually supplied in big bags or in steel drums.

Q:Carbide drills and high-speed steel drills, which are suitable for processing stainless steel 10?
If it's cylindrical carbide, it's better to be on the drill bit or as a guide
Q:What are the types of cemented carbides?
3. Indexable cutters, including indexable carbide end mills, indexable face mills, indexable dovetail cutters and indexable three edged blades.4 、 high speed steel cutting tools, including high-speed steel forming cutter, left-hand drilling, spherical milling cutter, cobalt high speed steel cutter and various non-standard high speed steel cutting tools.
Q:What is the difference between the raw and recycled materials of cemented carbides? The more specific, the better
Raw raw materials are raw materials, recycled materials have been used, and then recycled and re produced, raw materials than recycled materials used, and more pure materials.
Q:What material is that ultrafine cemented carbide?
You mean the ultra-fine grain cemented carbide, generally we have 0.6 alloy grain size is fine, which belongs to the tungsten carbide base hard alloy, ordinary tungsten carbide base hard alloy strength and hardness are higher than the same cobalt content. The process is mainly mixing, wetting, drying, forming, sintering, finishing, such as sand blasting, CVD/PVD coating, heat treatment, etc.
Q:What kind of clamp blade should be used for hard alloy?
Hard alloy tools are used for turning cemented carbides. Now the general superhard materials are PCD (polycrystalline diamond) and PCBN (poly cubic boron nitride)However, because carbide contains more carbon elements, PCD is easy to produce chemical dissolution (carbon affinity) during processing, so the PCBN blade should be considered.
Q:Japan steel tungsten carbide which is good
Japan steel tungsten carbide recommended Kunshan aloi precision mould Co. Ltd, Japan Istanbul technology research of copper tungsten alloy used for professional sales of Japanese steel tungsten carbide and discharge EDM, silver tungsten alloy, copper alloy; discharge EDM tungsten copper, copper thread electrode; non-standard thread electrode, thread grinding machining
Q:Can CBN wheels grind cemented carbide? Why?
Tungsten carbide and non-metallic ceramic materials are usually made of diamond grinding wheels.CBN can iron group elements of workpiece.According to the development trend of ordinary abrasive abrasive, > superhard abrasiveCorundum like A - >CBN BSilicon carbide C> diamond DThe rule: A sends to B, C develops D
Q:What kind of cemented carbide is the most wearable?
Tungsten particles smaller, higher hardness, higher wear resistance.Mainly depends on the use of conditions, the most wear-resistant carbide materials may be more brittle, so it may not be able to use.According to the hardness and toughness of cemented carbide is divided into several types, such as YG8, YG15 etc., is the wrong type of high speed steel has great influence on the service life, may your home (peak steel) inside with a tungsten component but not tungsten.Cemented carbide is a powder metallurgy process with tungsten carbide as the main body and sintered with cobalt or other bonded metals. The tungsten content of tungsten carbide is above 80%.Tungsten is a hard alloy. 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%.
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 the reason for the metallographic cavity (as shown in the drawing) of cemented carbide?
Too many factors, but according to the shape, size, number and distribution state can be roughly determined what caused by links.
