Ferro Silicon



Ferrosilicon is produced by reduction of silica or sand with coke in presence of scrap iron, millscale, or other source of iron.

Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferrosilicons with higher silicon content are made in electric arc furnaces.

An overabundance of silica is used to prevent formation of silicon carbide. Microsilica is a useful byproduct.

The melting point and density of ferrosilicon depends on its silicon content.

Q:What is the resistivity of the yg13 cemented carbide?
A brief introduction to YG13, tungsten steelYG13 is a kind of tungsten steel tungsten steel mold suitable for production of complex shape of the tungsten carbide, which is up to 4000MPa to its bending strength impact resistance performance is excellent, especially YG13 tungsten steel with moderate hardness, low pressure sintering is made of fine grain 0.6um alloy powder with high strength, good abrasion resistance by the large number of customers die trial, recognized by all say the same thing it is indeed a high ratio of tungsten steel mold materials, especially suitable for the production of powder pressing mould.
Q:What kinds of carbides are there? How should we choose in production?
Tungsten cobalt carbide (YG): suitable for brittle materials such as cast iron;Tungsten cobalt titanium carbide (YT): it is suitable for processing plastic materials, such as steel;General purpose cemented carbide (YW): commonly used for processing stainless steel, heat-resistant steel, high manganese steel and other difficult to process materials.
Q:Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?
They are hard and not afraid of annealing, but they are brittle. Also called tungsten titanium alloy. Hardness can range from HRB89 to 95, with characteristics that are difficult to wear.
Q:Tungsten steel could be used to do is hard alloy knife?
Of course you can need what specifications of tungsten steel knife
Q:Hard alloy drill, stainless steel.
Detailed analysis of the specific circumstances, the general drilling site is very smooth, you do not need to hit the center hole. If the borehole is uneven or drilled on the slope, a center hole is required. If the drill hole is first deflected and re corrected, a center hole is also required.
Q:What type of carbide for punching dies? Better. Where can I buy it?
Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
Q:The difference between cemented carbide and tungsten.
Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.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.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.
Q:Can hard alloy be used in food?
Used for processing food should not be possible, the composition of tungsten carbide.
Q:The wood cutting tools are made of hard alloy, high speed steel and diamond.
A total of 10 ~ 25%. Under the condition of heat generated in the high-speed cutting (about 500 C) can still maintain a high hardness of HRC can be more than 60. This is the main characteristic of high speed steel - red hardness. And carbon tool steel after quenching and low temperature tempering, at room temperature has very high hardness, But when the temperature is higher than 200 DEG C, the hardness decreased rapidly, at 500 DEG C hardness has been reduced to a similar degree with annealing state, completely lost the ability of metal cutting, which limits the production of carbon tool steel and high-speed steel cutting tools. The red hardness, make up for the fatal defect of steel with carbon. That can be used in the manufacture of cutting tools.
Q:Can YG813 carbide cutters be used for cutting stainless steel intermittently? How much is the cutting speed?
YG813Good wear resistance, high flexural strength and adhesive resistance. Suitable for processing high temperature alloy, stainless steel, high manganese steel and other materials.
