10 years history

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:What are the carbide inserts on the turning tool welded to the handle?
The common oxygen welding and brazing flux borax and welding line! The welding method is as follows: when welding, first use four carbon chloride (CCl4) to wash the welding section of the knife pole, and then use the oxygen and acetylene to turn the tool red and then sprinkle borax! Melt the copper into the top of the knife. Place the blade on the knife and continue to burn until the copper and alloy blades come in contact. An ordinary soldering knife comes out.
Q:What are the three types of commonly used cemented carbides?
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.K class (equivalent to China's YG class), cemented 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%).
Q:What industry does carbide belong to? Five
The original should belong to the tool industry, because the use of hard alloy cutting tools, cutting tools, do some, such as measuring. Now the application of cemented carbide is becoming more and more widespread, and it should be more machining.
Q:Which hardness is 5 of carbon steel and alloy steel?
T10 is a kind of carbon steel, carbon containing 1% carbon steel, excluding alloy elements, alloy steel is alloy element steel. The strength of carbon steel and alloy steel which has high hardness, not only carbon and alloy content, to look at the condition of heat treatment, even if the same carbon content of carbon steel and alloy steel under different heat treatment conditions, may be carbon steel high hardness alloy steel with high hardness can also be. Still do not understand this is not nonsense, domestic high quality steel, not only domestic technology is not in place, the user is not willing to pay a high price to buy high quality steel. Always want to spend less money to buy things, it is not possible.
Q:What is the hardness of cemented carbide?
Different grades, different hardness, usually (86 ~ 93HRA, equivalent to 69 ~ 81HRC);
Q:High end markets for cemented carbides
Chinese tool enterprises through continuous learning and strategic planning, has occupied half of the country, but in the market, enterprises in the development process and highlights several fatal problems, such as inadequate attention, improper handling, all these will seriously affect the development of enterprises.At this stage, carbide cutting tools in developed countries have accounted for the dominant position of the tool type, the proportion of up to 70%.
Q:What are the contents of cemented carbide production test 20
Fluorescence detection: fluorescence detectorScanning electron microscope: SEM scanning electron microscopeXRD: XRD testElectron microscopy: TEM projection electron microscopyMy school student, brother, I speak not all, you should all do so, detection cost is not expensive, but the equipment to buy it, not tens of millions of nabuxialai, and equipment is not the same.
Q:How hard is the carbide knife?
Seven or eight, Baidu is absolutely no problem.
Q:What kind of cemented carbide is used for processing HRC40 degrees stainless steel?
It is recommended to choose YS8 welding tool. Very good processing quality can be obtained.
Q:What is the difference between hard alloy and steel
Products: tungsten steel containing approximately 18% tungsten alloy steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness for the Vivtorinox 10K, second only to diamond. Because of this, tungsten steel products (a common watch), has the characteristics of not easy to be worn. Commonly used in lathe tool, drill, impact drill glass knife head, tile cutter, hard annealing, but brittle. Hard alloy: powder metallurgy hard alloy belongs to the category of metal ceramic is also known as metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxide (such as Al2O3, ZrO2 etc.) as the main ingredient, adding proper amount of metal powder (Co Cr, Mo, Fe, Ni, etc.) made by powder metallurgy method, has some characteristics of metal ceramic.
