Kev lag luam Q&A: Puas muaj ntau qib ntawm Ferrosilicon?
Tau-ferrosilicon (FeSi) los ntawm ntau qib, thiab qib koj xaiv tuaj yeem cuam tshuam rau deoxidation lub zog, silicon rov qab, tswj impurity, thiab tag nrho cov nqi. Rau ntau tus neeg yuav khoom, cov lej qib saib yooj yim (75, 72, 65…), tab sis hauv kev yuav khoom tiag tiag, "qib txoj cai" nyob ntawm seb koj tsim thiab nruj npaum li cas koj cov kev xav tau zoo. Nov yog cov lus nug cov neeg yuav khoom nug feem ntau.
Q&A
Q1: Qhov "qib" hauv ferrosilicon txhais li cas?
Feem ntau, qib yog hais txog qhovsilicon (Si) cov ntsiab lus. Yog li qib siab dua txhais tau tias feem pua silicon ntau dua. Piv txwv li:
FeSi 75yog kwv yees li 75% silicon
FeSi72yog kwv yees li 72% silicon
FeSi65yog kwv yees li 65% silicon
Cov seem yog cov hlau, ntxiv rau me me ntawm lwm cov ntsiab lus uas feem ntau teev ua impurities ntawm COA.
Q2: Cov qib twg muaj ntau tshaj plaws hauv kev lag luam thoob ntiaj teb?
Cov qib kev lag luam tshaj plaws yog:
FeSi 75- qhov nrov tshaj plaws thoob ntiaj teb, siv dav hauv steelmaking thiab siab dua -requirement applications
FeSi72- feem ntau rau cov qib steel dav dav thiab tus nqi -sensitive purchasing
FeSi65- siv hauv cov chaw tsim khoom thiab cov ntawv thov yooj yim uas tswj hwm tus nqi tseem ceeb dua
Hauv ntau lub khw, FeSi75 thiab FeSi72 yog tus thawj vim tias lawv haum rau feem ntau ntawm kev thov steel.
Q3: Puas muaj qib "tshwj xeeb" ntxiv rau FeSi75/72/65?
Yog lawm. Nyob ntawm lub teb chaws thiab daim ntawv thov, koj kuj yuav pom:
Tsawg-Aluminium FeSi(thov thaum Al yuav tsum tau tswj)
Tsawg-phosphorus / qis-sulfur FeSi(rau cov hlau huv)
FeSi hmoov / milled FeSi / atomized FeSi( cais ntau dua los ntawm daim ntawv tshaj li qib silicon)
FeSiMg (Magnesium ferrosilicon)siv rau nodular cam khwb cia hlau kho
Cov no tsis yog ib txwm cais "tus lej," tab sis lawv tseem suav tias yog cov khoom sib txawv vim lawv tsom cov txheej txheem tshwj xeeb xav tau.
Q4: Kuv yuav xaiv cov qib zoo li cas rau kuv daim ntawv thov?
Ib txoj hauv kev yooj yim yog kom phim qib rau koj qib uas xav tau:
Yog koj xav taumuaj zog deoxidation thiab ruaj khov silicon rov qab, FeSi75 feem ntau yog qhov kev xaiv zoo dua.
Yog koj uaGeneral carbon hlauthiab xav tau tus nqi zoo dua, FeSi72 feem ntau txaus.
Yog koj tsom raucasting los yog metallurgy yooj yim, FeSi65 tuaj yeem yog qhov kev xaiv siv tau.
Yog tias koj qib steel yog rhiab rau impurities (P, S, Al, C), ces cov qib silicon ib leeg tsis txaus - koj yuav tsum saib cov impurity txwv hauv COA.
Q5: Puas yog qib siab dua ib txwm txhais tau tias zoo dua?
Tsis tas li. Cov ntsiab lus silicon siab dua txhim kho kev ua tau zoo, tab sis "zoo dua" nyob ntawm koj lub hom phiaj. Rau ntau cov nroj tsuag, FeSi72 ua haujlwm zoo kawg nkaus thiab muaj kev lag luam ntau dua.
Tsis tas li, ob tus neeg xa khoom tuaj yeem muab "FeSi75," tab sis lawv cov kev tswj tsis huv thiab kev sib xws yuav txawv. Tias yog vim li cas cov neeg yuav khoom tau tshawb xyuas ob qho tib siqibthiabCOA stability, tsis yog qib naj npawb ib leeg.
Hais txog peb cov khoom
Peb muabFeSi75, FeSi72, thiab FeSi65nyob rau hauv ntau qhov sib txawv me me, nrog kev ruaj khov muaj pes tsawg leeg thiab tswj impurities rau steelmaking thiab foundry siv. Yog tias koj qhia peb koj lub hom phiaj qib steel, qhov loj me, thiab qhov chaw xa khoom, peb tuaj yeem faib COAs tsis ntev los no thiab pab koj xaiv qib uas haum tshaj plaws -ntxiv rau muab cov nqi FOB tshiab thiab cov kev xaiv ntim khoom.
