Basic idea:FerroalloyIt is the alloy that comprises by the element such as iron and silicon, manganese, chromic, titanium, ferroalloy is one of raw material of steel-making, the deoxidizer that makes steel when steel-making and alloying element additive are used. Ferroalloy is the important raw material of steel-making and cast steel, mix in steel-making when casting, use as deoxidizer, desulphurization agent and alloy additive. The natural science that can improve steel turns the mechanical performance of function and cast, mechanical, national defence, nicety is made, the industry such as daily expense home appliance is higher and higher to the requirement of material, taller and taller also to the requirement of ferroalloy. UtilityFerroalloyBasically use the deoxidizer in regarding steel-making as the process, alloying constituent. The need when deoxidizer steel-making is added a few as stronger as oxygen adhesion, and its oxide can successful eliminate from inside steel and metallic stuff fluid, make the oxygen content in steel and metallic stuff fluid is reduced thereby. The deoxidizer with commonly used • has calcium of ferrosilicon, ferromanganese, aluminous iron, silicon (iron) , silicon manganese (iron) , silicon barium (iron) , silicon is aluminous (iron) etc. Alloying constituent • joins all sorts of ferroalloy to adjust its chemistry component in carbon steel, producible an all sorts of alloy steel and new metal stuff. The alloying constituent with commonly used • basically has: Iron of iron of ferrosilicon, ferromanganese, ferrochrome, molybdenum, ferrotungsten, titanium, niobium iron, vanadium iron, ferronickel. Additional, the ferroalloy that also needs other breed in ferroalloy oneself production reductive or adjust composition, if ferrosilicon can use the reducer that is iron of ferromanganese, molybdenum; Charcoal element ferrochrome is the main raw material of smelt silicon chromic alloy, and the main raw material that silicon chromic alloy is humble ferrochrome. Ferroalloy is like in other sphere in welder course of study, ferromanganese pink, ferrotungsten pink, molybdenum iron pink is the main raw material of special type welding rod. Our country of • of macroscopical adjusting control is the biggest on the world at presentFerroalloyProduce country, consumption country and exit country. Ferroalloy of • our country year productivity is close to 20 million tons. • our country is annual ferroalloy consumption is controlled in 11 million tons. • is in our country ferroalloy productivity is serious and superfluous. • in last few years, in the light ofFerroalloyProduced can superfluous country to publish a variety of limitation measure.
