Yog koj yuav75% qis-Aluminium ferrosilicon (Low-Al FeSi75), koj tab tom thov rau ob yam tib lub sijhawm:
siab silicon(yog li nws ua haujlwm zoo li deoxidizer / alloy) thiab
qis aluminium(yog li nws tsis coj pliaj Al rau hauv koj cov hlau lossis cov txheej txheem casting).
Nov yog cov ntsiab lus tseem ceeb uas cov neeg yuav khoom feem ntau xav paub meej.
Khoom Description
Q1: Dab tsi yog "75% qis-aluminium ferrosilicon" txhais tau li cas?
Nws txhais tau tias cov khoom yogFeSi75 qib(yog li cov qib silicon yog nyob ib ncig ntawm 75%), tab sis nrog ib qho kev xav tau ntxiv:aluminium (Al) yuav tsum khaws cia qis dua li qub.
Vim li cas?
Vim tias txhuas tuaj yeem cuam tshuam rau kev suav nrog, kev huv huv, thiab qee zaum ua tiav qhov kawg -tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem uas nkag siab rau Al pickup.
Yog li:FeSi75 qhia koj qib silicon. Tsawg-Al qhia koj tias qhov kev txwv txhuas yog nruj dua.
Q2: Dab tsi yog qhov "tseem ceeb" cov neeg yuav khoom xav tau rau Low-Al FeSi75?
Cov neeg yuav khoom sib txawv thiab kev lag luam teeb tsa sib txawv, tab sis ib qho "kev lag luam-style" cov ntawv txheeb xyuas zoo li no:
Silicon (siv):feem ntauNtau dua lossis sib npaug li 75%(feem ntau nyob ib ncig ntawm 74-76% hauv COA tiag)
Al (Aluminium):"low" feem ntau thov raws liTsawg dua lossis sib npaug li 1.0%, thiab qee tus neeg yuav khoom thawb qis dua (xws liTsawg dua lossis sib npaug li 0.8%los yogTsawg dua los yog sib npaug li 0.5%)
P (phosphorus):feem ntauTsawg dua lossis sib npaug li 0.04%
S (Sulfur):feem ntauTsawg dua lossis sib npaug li 0.02%
C (Carbon):feem ntau nyob ib ncig ntawmTsawg dua lossis sib npaug li 0.2%(nws txawv ntawm kev siv)
Cov lej yuav tsum phim koj daim ntawv thov. Piv txwv li, yog tias koj ua cov hlau huv, koj yuav xav tau nruj dua P thiab S ib yam nkaus -tsis yog Al tsawg.
Q3: Vim li cas tib neeg thiaj li mob siab rau qis txhuas hauv FeSi75?
Vim tias txhuas tuaj yeem ua teeb meem hauv qee cov kab ntau lawm. Cov neeg yuav khoom feem ntau xav tau qis Al thaum lawv xav tau:
Cov hlau huv huv(tsawg dua qhov tsis xav tau suav nrog)
Ntau ruaj khov chemistry tswj(tsis txhob "Al pickup")
Sensitive steel qibqhov twg me me hloov teeb meem (qee alloy steels, tshwj xeeb steels, thiab lwm yam)
Ntau tus neeg yuav khoom tsis mloog ib txwm Al rau kev tsim steel. Tsawg-Al feem ntau yog thov thaum kev tswj xyuas zoo nruj dua lossis thaum tus neeg siv khoom muaj teeb meem ua ntej.
Q4: Dhau li ntawm chemistry, dab tsi lwm yam "specs" cov neeg yuav khoom feem ntau lees paub?
Hauv kev txiav txim tiag tiag, lo lus "specification" feem ntau suav nrog cov ntsiab lus ntawm lub cev ib yam nkaus:
Particle loj (kev xaiv ntau):
10-50 hli(ntau heev rau steelmaking)
10-100 hli(rau qhov cub loj)
3-8 hli / 1-5 mm(rau ceev melting los yog refining kauj ruam)
Ntim (kev xaiv ntau):
1 MT jumbo hnab
25 kg hnab (feem ntau nrog hauv ob sab phlu)
Kev tiv thaiv noo noo yog xa mus rau thaj chaw ntub dej
Yog tias koj siv qhov me me, ntim khoom tseem ceeb dua vim tias kev nplua tuaj yeem nqus cov dej noo thiab tsim kev tuav pov hwm ntau dua.
Q5: Kuv yuav tsum nug tus neeg muag khoom dab tsi kom paub meej ua ntej yuav Tsawg-Al FeSi75?
Txhawm rau kom tsis txhob nkag siab yuam kev, cov neeg yuav khoom feem ntau nug peb yam yooj yim:
Cov qauv COA tsis ntev los noqhia Si + Al + P + S + C
Ib daim ntawv lees paub ntawmAl txwv(piv txwv li, "Al Tsawg dua lossis sib npaug li 1.0%")
Kev lees paub ntawmqhov loj me thiab max nplua(yog li koj tsis tau txais hmoov ntau dhau)
Yog tias tus neeg muag khoom tuaj yeem pom COA zoo ib yam ntawm cov khoom sib txawv, nws yog lub cim zoo ntawm "qis-aluminium" yuav tsum tau tswj tiag tiag, tsis yog daim ntawv lo lag luam xwb.
Hais txog peb cov khoom
Peb muabFeSi75 qis- txhuasqib nrog cov ntsiab lus silicon ruaj khov thiab tswj cov qib txhuas, thiab peb tuaj yeem muab ntau qhov sib txawv xws li 10–50 mm, 10–100 mm, thiab cov granules me me raws li koj txoj kev melting. Yog tias koj qhia peb koj daim ntawv thov thiab nyiam Al txwv, peb tuaj yeem qhia COAs tsis ntev los no thiab muab cov nqi FOB tshiab thiab cov kev xaiv ntim khoom los txhawb koj txoj kev yuav khoom.
