Hauv cov liaj teb ntawm hlau thiab hlau metallurgy thiab casting,ferrosilicon 75tau dhau los ua cov khoom tsis tseem ceeb vim nws cov khoom tshwj xeeb. Nws cov kev ua tau zoo sib xws nrog nws muaj pes tsawg leeg, thiab cov kev hloov me ntsis nyob rau hauv cov muaj feem yuav muaj qhov cuam tshuam tseem ceeb ntawm nws txoj kev siv. Yog li, qhov hloov pauv li cas hauv kev sib xyaw ntawm 75 ferrosilicon cuam tshuam nws txoj kev ua tau zoo? Tom ntej no, peb yuav tshawb txog nws hauv qhov tob.
Raws li lub npe qhia, Ferro Silicoron 75 muaj txog 75% silicon (si), thiab tus so yog tsuas yog hlau (fe). Nws tseem muaj ib qho me me ntawm cov neeg tawg hlab nplej xws li carbon (c), manganese (mn), phosphorus (p), thiab leej faj (cov leej twg. Cov khoom siv no cuam tshuam nrog txhua lwm yam thiab ua ke txiav txim siab cov yam ntxwv ua kom zoo ntawmFesi 75.
Qhov cuam tshuam ntawm kev hloov pauv hauv cov ntsiab lus silicon ntawm kev ua tau zoo
Silicon yog cov tseem ceeb tivthaiv ntawmFERRO Silicon 75%, thiab kev hloov pauv ntawm nws cov ntsiab lus ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawmferrosiliconCov. Thaum cov ntsiab lus silicon nce, qhov muaj peev xwm txo tau ntawm ferrosilicon yog txhim kho. Hauv cov txheej txheem statmaking, qhov no txhais tau hais tias nws tuaj yeem tshem tawm cov hlau, thiab txhim kho cov roj av oxygen, thiab txhim kho cov hlau oxygen, yog li ua kom muaj cov hlau siab dua. Piv txwv li, thaum ua kom muaj cov roj carbon ua haujlwm siab zoo, kom ua tau cov khoom ua si tsis zoo, thiab txo cov khoom lag luam tsis zoo thiab ua kom muaj qhov tsis zoo los ntawm cov ntsiab lus oxygen ntau.
Ib qho ntxiv, qhov nce hauv cov ntsiab lus silicon tseem yuav txhim kho lub hardness thiab hnav tsis kam ntawm ferrosilicon. Nyob rau hauv lub foundry kev lag luam, ntxiv High-silicon Nws yog dav siv nyob rau hauv kev tsim cov khoom ntawm ntau cov kev hnav-resistant, xws li cov ris-resistant liners rau tsuas yog ntawm cov tshuab thiab cov zaub rau dov cov khoom siv.
Txawm li cas los xij, yog tias cov ntsiab lus silicon txo qis, deoxidation cov nyhuv ntawm ferrosilicon alloy yuav tsis muaj zog, uas yuav ua rau tsis muaj phom sij thiab cuam tshuam rau cov hlau ua kom zoo thiab ua tau zoo ntawm cov hlau; Nyob rau tib lub sijhawm, nws lub luag haujlwm yog ib qho inoculant los txhim kho cov kev ua tau zoo ntawm cov hlau pov tseg, thiab nws yuav nyuaj rau cov kev xav tau ntawm cov khoom siv zoo.
Qhov cuam tshuam ntawm cov ntsiab lus carbon cov ntsiab lus hloov ntawm kev ua tau zoo
Cov pa roj carbon cov ntsiab lus hauv 75ferrosilicon feem ntau yog tsawg, tab sis txawm tias qhov kev hloov me me yuav cuam tshuam nws qhov kev ua tau zoo. Kom muaj kev nce ntxiv cov pa roj carbon cov ntsiab lus yuav txo cov melting point ntawm ferrosilicon. Hauv cov txheej txheem statmaking, cov xeeb ceem no ua rau ferrosilicon yooj yim dua rau cov khoom siv tshuaj lom neeg, thiab ua kom luv luv lub sijhawm steelmaking, thiab txhim kho ntau dua kev ua haujlwm.
Txawm li cas los xij, nws yuav tsum raug sau tseg tias ntau cov ntsiab lus carbon ntau dhau yuav muaj qhov tsis zoo rau kev ua tau zoo ntawm cov hlau. Cov pa roj carbon ntau yuav txo cov tawv thiab corrosion tsis zoo rau kev siv tawv thiab corrosion tsis kam, xws li choj kev tsim kho thiab nkoj. Ntau cov ntsiab lus carbon ntau yuav cuam tshuam rau kev pabcuam lub neej thiab kev nyab xeeb ntawm cov hlau. Yog li no, cov pa roj carbon nyob rau hauv ferrosilicon75 yuav tsum tau nruj me ntsis tswj tsis muaj ntau yam.
Qhov cuam tshuam ntawm kev hloov pauv hauv manganese cov ntsiab lus ntawm kev ua tau zoo
Manganese tseem yog ib qho ntawm cov khoom tseem ceeb hauv 75 fesi. Tus nqi ntawm manganese tuaj yeem txhim kho lub zog thiab tawv ntawm ferrosilicon. Hauv kev tsim cov hlau tshwj xeeb, xws li cov hlau loj tshwj xeeb, ua kom cov khoom siv zoo nkauj thiab cov khoom siv nruj ua ke los txhim kho cov kev siv tshuab
Ib qho ntxiv, manganese kuj muaj cov nyhuv ntawm kev txhim kho lub corrosion tsis kam ntawm Ferro Silicon. Nyob rau hauv kev tsim cov corrosion-resistant steel, manganese thiab silicon thiab lwm yam kev sib koom tes los hloov cov xim oxide, yog li ntawd cov hlau tuaj yeem siv nrog cov tshuaj pleev xim rau hauv cov tshuaj lom neeg xws li tshuaj lom neeg thiab cov tubrog.
Qhov cuam tshuam ntawm kev hloov pauv hauv phosphorus thiab cov tub ntxhais cov ntsiab lus ntawm kev ua tau zoo
Phosphorus thiab leej faj yog kev tsim txom impurity ntsiab hauv 75 # ferrosilicon, thiab kev hloov pauv hauv lawv cov ntsiab lus tau ua kom raug mob rau kev ua haujlwm ntawm ferrosilicon. Kev nce hauv phosphorus cov ntsiab lus yuav ua rau mob khaub thuas txias ntawm ferrosilicon, ua rau nws tsis yooj yim hauv ib puag ncig tsawg thiab nquag mus rau brittle begiture. Hauv kev tsim cov hlau rau cov vess-kub siab thiab cov hlau ua kom muaj zog, yog tias ferrosilicon)
Qhov nce hauv cov ntsiab lus Sulfur yuav nce kub brittleness ntawm ferrosilicon, thiab cov kab nrib pleb zoo li thaum lub sijhawm ua forging thiab dov, cuam tshuam rau kev ua haujlwm zoo thiab ntau lawm. Nyob rau tib lub sijhawm, leej faj yuav kuj yuav txo qis cov tawv, qaug zog thiab lwm yam khoom ntawm cov hlau, muaj kev puas tsuaj ntawm cov hlau. Yog li ntawd, hauv kev tsim khoom thiab siv Ferro Silic Silicon 75, cov ntsiab lus ntawm phosphorus thiab leej faj yuav tsum raug tswj hwm kom tswj tau qis dua.
Hauv cov ntsiab lus, kev hloov pauv ntawm silicon, carbon, manghologes, phosphorus, phosphorus, sulphorus, cov tib yam nyob hauv Fesi Alloy 75% yuav muaj ntau qib sib txawv ntawm nws cov kev ua tau zoo. Nyob rau hauv kev lag luam tiag tiag ntawm kev lag luam xws li hlau metallurgy thiab cam khwb cia los muab cov kev sib nkag siab ntawm txhua qhov kev hloov pauv ntawm txhua qhov kev hloov pauv ntawm cov hlau thiab cov khoom siv siab, thiab ua kom tau raws li cov kev xav tau ntawm cov kev xav tau sib txawv. Nrog kev txhim kho kev lag luam txuas ntxiv ntawm kev lag luam thev naus laus zis, kev tshawb fawb ntawm kev sib xyaw thiab 75 ferrosilicon alloy tseem yuav txuas ntxiv kom txhawb nws daim ntawv thov thiab kev loj hlob hauv ntau daim teb.
