Silica-manganese alloy

一、The use of silica-manganese alloy
1.deox i d i zer and desu l phur I zation element it is too strong of affinity of Mn.0 and S.So Mn is deoxidizer and desu l phurization elemen of steel l iquid, in steel making a part of iron were oxidized.
Fe0 produced was dissolved in steel liquid it reduced steel function .Thus it must be deoxidized in l ater stage of stee l making producing . Due to the affinty of Mn and 0 stronger than Fe and 0 , so Mn can deprive 0 in Fe0t oform Mno that didn’t dissolved , almost all steeler must use ferromanganese to dexidize , in steel making Mn can reduce Fes to produce Mn stabi l i zed . Mns can’t dissolved in steel l iquid . The Mn is desulphur I zation element .
2.It is used to be iron casting element .
Mn is used to be alloy element added to steel liquid that let steel alloyed it can improve the mechanical property of steel and enhancing the intensity hardess element ind ispensable almost all of steel contain a little Mn .
3.Mn can improve t the property of casting iron when we are casting iron . add Mn to iron that can improve the phys I cal property and mechanical property of casting one . For example,it can enhance their intensity and wear ability and soon .
4.Silica-manganese alloy’s use in other ways
Great majority Mn is used to be iron and steel producing according to ferromanganese silica-manganese alloy can be used to be compound deoxidizer and alloy element it can be used to be the raw and processed mater ials of ferromangese with low carbon and metal manganese in proucing . Metal manganese is used to be the alloy element of Mn to produce stainless steel .
Mn and N of MnFeS all are used to be alloy element at the same time insteelmaking N can enhance steel’s intensity and plasticity. .It was used to produce Chromium manganese nitrogen and stainless steel .

二、silicomangan production method
The manganese silicon alloy all is that the simultaneous carbon deoxidation manganese ore (include the rich manganese residue) composes in reply with oxide manganese in silica silicon dioxide but refines out be useful in hot stove of ore. Adopt smelt equipment and operating method as smelt high-carbon ferromanganese iron basic .
The law producing the silicon fever supplying electricity smelt high silicomanganese silicon alloy used by metal manganese over adopt two footwork , is to use rich manganese residue to produce iron content , very low high phosphorus fero-manganesesilicon first , uses that height fero-manganesesilicon , silica and reducer to smelt the high silicomanganese silicon alloy and then again. Since smelt development of technology, adopt an elephant to smelt one average silicomangan-like so-called footwork nowadays.
The temperature needs height since silication manganese deoxidation is required , the in addition what of uses ore grade hangs down , this needs right away than smelt the higher stove of high-carbon ferromanganese iron temperature. Than smelt high-carbon, ferromanganese iron leaves out high repeated voltage and electrode current density therefore , in common use. Example 1800 kVA repeated voltage is 80 ~ 84 V , 9000 repeated kVA voltage is 126 ~ 133 V.
