Dab tsi yog tus nqi ntawm tsawg aluminium ferrosilicon hnub no?

ferrosilicon nroj tshuag:​Lub ferrosilicon nroj tsuag yog qhov chaw muaj kev lag luam tshwj xeeb hauv kev tsim ferrosilicon, ib qho alloy ntawm hlau (FE) thiab silicon (si). Nws cov haujlwm tseem ceeb muaj:

​Ua Khoom Siv Raw:Tau txais thiab npaj cov tswv yim zoo li silica (sio₂ los ntawm quartzite / xuab zeb), hlau ore / seem, thiab carbonaceous txo cov neeg sawv cev (CEE / COE).

​SMELTING:Kev ua haujlwm loj loj hluav taws xob lub tshuab hluav taws xob (feem ntau 6-20 MVA) los ua kom sov tus nqi ntawm ~ 1,800-2

​Alloy Kev Kawm:Tswj cov ntsiab lus silicon (piv txwv li, 45%, 65%, 75%, 75%, 75% SI) los ntawm kev kho cov khoom siv raw piv.

​Tshaj tawm - kev:Tapping molten ferrosilicon, txias nws (ntawm dej lossis huab cua), thiab ua rau hauv cov pob, granules, lossis hmoov rau kev faib tawm.

Ferrosilicon Kev Ua Lag Luam:​​Lub ntiaj teb ferrosilicon kev ua lag luam yog cuam tshuam los ntawm ntau yam:

​Kev lag luam hlau:~ 80% ntawm ferrosilicon yog siv hauv kev phom sij statmaking (xws li kev loj hlob / aloy additive), yog li kev loj hlob hauv kev tsim kho steel (piv txwv li kev tsim kho, tsheb) ncaj qha drives ncaj qha.

​Txhuas Alloy Ntau Lawm:Ferrosilicon yog qhov tseem ceeb rau kev tsim cov magnesium - ferrosilicon (mg {} fesi

​Txuas txuas ntxiv dag zog:Silicon rau hnub ci panels thiab semiconductors relies ntawm siab {{purity ferrosilicon (piv txwv li cov pub mis, tsav tsheb lom neeg kev lag luam.

​Dynamics:Tuam Tshoj ua tsis tau ntau lawm (~ 60% ntawm cov nqi hauv ntiaj teb) vim cov khoom siv qis thiab cov khoom siv raw; Russia, Norway, thiab Is Nrias teb yog lwm tus neeg tseem ceeb players.

​Cov nyom:Kev siv hluav taws xob tsis huv (cov hluav taws xob yuav tsum siv hluav taws xob) thiab cov kev cai ib puag ncig (emission tswj) cuam tshuam.

ferrosilicon ntom:​Ferrosilicon lub ntom ntom los ntawm2.8-3.2 g /m³, Nyob ntawm cov ntsiab lus silicon:

​Qis dua li cov qib (piv txwv li, 15-45% SI):Ntau dua (~ 3..2 g / cm³) vim tias hlau (ntom tshuaj (ceev ~ 7.87 g / cm³) yog feem ntau feem.

​Ntau cov qib siab silicon (piv txwv li, 75-90% SI):Qis dua (~ 2.8-2.9 g / cm³) raws li silicon (ceev faj ~ 2.33 g / cm³) ua tus tseem ceeb.

Impurities (piv txwv, calcium) lossis aloying additives (piv txwv li manganese, chromium) tuaj yeem hloov me ntsis, tab sis silicon cov ntsiab lus yog thawj qhov tseem ceeb.

​Dab tsi yog ferrosilicon siv rau:​Ferrosilicon yog ntau yam nyob rau hauv kev lag luam:

​Metallurgy:​

Deoxidizer:Tshem tawm oxygen los ntawm Molten Hlau (reacting nrog o₂ los ua sidio₂ slag), txhim kho cov qauv kev ua yeeb yam.

Alloy Additive:Txhim kho lub zog, hardness, thiab kub ua hauj hauv tshav hlau (piv txwv li, cov hlau caij nplooj ntoos hlav, tuam hlau.

​Nrhiav Kev Lag Luam:Ua raws li tus inoculant nyob rau hauv Magocumles ferrosilicon alloys rau cleacy tus qauv hauv txhuas cov txheej txheem, txo tus porosity.

​Tshuaj lom neeg:Ua hauj lwm ua tus neeg sawv cev txo cov khoom lag luam silicon {{0 х}, sexbide, silicon carbide) lossis silicon rau semiconductors.

​Vuam:Ntxiv rau cov electrodes kom ruaj khov arcs thiab txhim kho weld zoo.

​Refractories:Siv nyob rau hauv high - kub refractory cib rau rauv taws vim nws cov cua sov tsis kam.

ferrosilicon rau hlau:​Ferrosilicon yog qhov tsis tseem ceeb hauv steelmaking rau ob qho tseem ceeb:

​Oxygen tshem tawm (Deagidation):Thaum lub sij hawm hlau ua kom zoo, yaj oxygen nyob rau hauv molten hlau ua rau brittleness. Ferrosilicon reacts tau exothermically nrog oxygen (4fesi+ 7} sio₂), tsim slag uas floats mus rau saum npoo, huv cov hlau.

​Alloy ntxiv dag zog:Los ntawm kev ntxiv silicon (cov khoom -}}}}}}}}}}}} }ancesilicon txhim kho cov khoom siv me me:

Nce paib lub zog thiab tensile lub zog (tseem ceeb rau cov qauv hlau qauv).

Txhim kho cov khoom siv nyuaj (muaj peev xwm los ua martensite thaum quenching), pab tau nyob rau hauv Tool Steels.

Enhances Elastic Modulus, ua cov hlau tsim rau kev ua haujlwm rau springs thiab siab - kev ntxhov siab.

Tsis muaj ferrosilicon, ua tiav cov hlau zoo thiab kev ua tau zoo yuav yog yuav luag tsis yooj yim.
