Ferro silicon is used to reduce metals from their oxides and deoxidize steel. It also prevents the loss of carbon from molten steel, and can be added to ferromanganese, spiegeleisen, silicides of calcium, and cast iron to accelerate graphitization.
Nevertheless, not all types of quartzes and quartzites are suitable for carbothermic reduction. Quartz Macedonia, for example, became unstable at high temperatures and disintegrated.
FESA produces high-quality ferro silicon with a typical purity of 98%. It is produced in electric arc furnaces and milled to specified size. It is available in a range of sizes and contains aluminum and titanium to provide corrosion resistance. It is suitable for heavy media density and sink-float applications. It can be blended with granulated magnesium and calcium to form a nodulizer that is especially effective in reducing chill.
It is a highly-effective inoculant for gray and ductile iron. Its use results in significantly reduced chill amounts and superior casting performance. It is primarily recognized for its ability to reduce the amount of alloy additions needed to obtain equivalent chill depths.
This is due to the fact that it has a very low level of Calcium and a very low Aluminum content. This allows the IM SR to react with liquid iron very rapidly and causes a minimum of dross formation when compared to other complex inoculants.
Ferro Silicon Strontium manufacturers offer agglomerated, de-oxidized and powdered ferroalloys. Capabilities include agglomeration, alloying, blending, carburization, classification, sintering and spheroidizing. Manufacturers also provide custom packaging, pressing, flow enhancement and milling. Serves the aerospace, automotive and commercial industries.
This inoculant is especially effective for thin-walled chilled sweet ash sulfur cast iron and steam and water pressure gray iron. It reduces white without significantly increasing eutectic silicon, improves matrix morphology and reduces casting defects such as hot spots and shrinkage. It is also a good nodulizer for nickel ductile iron.
This supplier offers magnetic ferro silicon that is produced in electric arc furnaces and milled to specified size. It is available in a variety of mesh sizes and contains aluminum and titanium, which provides corrosion resistance. Finished product is offered in bulk and bagged. Also carries a wide range of ferro silicon dross and inoculants. Provides custom and toll fusion formulating, grinding, particle sizing, analysis, sintering, atomization and heat treatment services.
Ferro Silicon Strontium suppliers supply the raw material needed to manufacture various steels and alloys. These products are available in a variety of forms, including lump, granular, powder and slurry. They are used in the cast iron, metallurgy, chemical and electric industries. They are also a key ingredient for the production of nuclear energy and semiconductors.
The major players in the market include Elkem ASA, Eurasian Resources Group, Ferroglobe, OM Holdings Ltd, and SINOGU CHINA. They are the largest producers of rare-earth elements, such as monazite (Ce, La)PO4, xenotime (YPO4), bastnasite (Ca(Ce,La)(CO3)2[CO3]3F2), and gadolinite Y2FeBe2Si2O10.
The major producers in this market offer different grades of products. Those with low aluminium and calcium content are best for grey and cast iron. They can remarkably reduce the chill phenomenon, and produce less slag residue. They are also suitable for water pressure and steam gray iron, owing to their superior inoculating properties. Moreover, these products have high reactivity and stability in the smelting process.
Ferro Silicon Strontium is an industrial product that is a mixture of calcium, silicon and iron. It is widely used in the steel industry as a deoxidizer and desulfurizer. It can control the size and shape of oxygen inclusions, and it can also reduce sulfide inclusions. It can also increase the fluidity and ductility of the metal.
It can be combined with barium to become ferro silicon strontium inoculant,which can remarkably reduce the chill phenomenon of casting and produce less shaped residue. It can also make the cast iron have high corrosion resistance.
It is also widely used in low alloy structural steel, composite steel, spring steel and bearing steel, and electrical silicon steel. It is also a popular raw material for the production of non-ferrous metals and chemical industry. It is a good product for low-alloy structural steel, nodular cast iron and steam and water pressure gray cast iron. It is a powerful deoxidizer for low-alloy steel, because both calcium and silicon have strong affinity with oxygen, and they can effectively reduce the oxides of carbon and sulfur in the molten steel.
