Ferrosilicon 75 rau Casting: Qib Tiag Tiag
Ferrosilicon tau hais los ntawm cov ntsiab lus silicon, thiab tus lej hauv qib npe yog qhov tsawg kawg nkaus silicon daim duab. FeSi75 txhais tau hais tias cov hlau tsis muaj tsawg dua 75 feem pua silicon; FeSi72 txhais tau tias tsis tsawg dua 72 feem pua; FeSi65 txhais tau tias tsis tsawg dua 65 feem pua. Rau ib tug foundry qhov txawv tsis yog kev kawm. Silicon ntxiv los ntawm FeSi nce cov ntsiab lus ntawm silicon ntawm cov hlau, tswj qhov tob tob hauv cov hlau grey, thiab ua raws li cov inoculant thaum nws ntxiv lig hauv kev kho mob raws li qhov loj me me. Vim tias silicon yog cov khoom uas tab tom yuav, tus neeg yuav khoom them rau ib chav tsev ntawm silicon, yog li qis dua -qib alloy tuaj yeem pheej yig dua rau ib tonne thiab tseem yuav kim dua rau ib chav tsev ntawm silicon xa mus rau lub ladle.
Chemistry Bands Qhov Tseem Ceeb hauv Kev Siv Foundry
| Parameter | Hom kev lag luam band | Vim li cas thiaj tseem ceeb |
|---|---|---|
| Silicon | tsis tsawg dua 72, 75 lossis 65 feem pua ntawm qib | lub ntsiab yuav khoom, tswj txias thiab silicon qib |
| Aluminium, qis- qib aluminium | qis dua 0.1 feem pua lossis qis dua 0.5 feem pua | tsawg aluminium txwv pinhole thiab roj tsis xws luag hauv castings |
| Cov pa roj carbon | feem ntau qis dua 0.2 feem pua | Cov pa roj carbon ntau cuam tshuam rau kev tawg hauv cov yaj |
| Sulfur thiab phosphorus | tswj kom qis residual theem | cov khoom seem nqa mus rau hauv cov hlau kawg |
| Qhov ntau thiab tsawg | 10-50mm, 10-100mm, 3-10mm, nplua | Dissolution tus nqi thiab inoculation nyhuv |
GB / T 2272 rau ferrosilicon thiab ISO 5445 rau ferrosilicon specification tau teeb tsa cov qauv qib thiab cov xwm txheej xa khoom, suav nrog cov feem me me. Daim ntawv xaj yuav tsum yog li ntawd hais txog qib, cov chav kawm txhuas yog cov roj tsis xws luag muaj kev txhawj xeeb, qhov loj me, thiab cov ntim khoom, vim hais tias tib qib muab raws li 10 mus rau 50 mm lumps thiab nplua coj txawv kiag li nyob rau hauv ib tug ladle los yog nyob rau hauv ib tug inoculation kwj.
Kev Siv Tus Nqi Theem rau Ferrosilicon
Cov lus hauv qab no sau tseg cov lus hais tau pom thaum Lub Xya Hli 14. Export theem yog USD ib tonne FOB Tianjin Chaw nres nkoj. Cov qib hauv tsev yog yuan ib tonne, ntuj thaiv, ex- ua haujlwm nyiaj ntsuab nrog rau se, thiab siv rau cov khoom siv aluminium qis.
| Export qib | Nqe: USD/tonne FOB Tianjin |
|---|---|
| Ferrosilicon 72 | 1,000-1,030 Nws |
| Ferrosilicon 75 | 1,080-1,100 Nws |
| Cov khoom siv hauv tsev | Specification | Thaj chaw | Tus nqi siv, yuan / tonne |
|---|---|---|---|
| Tsawg aluminium ferrosilicon | Si75, Al qis dua 0.1 feem pua | Qinghai | 6,700 txog 6,750 |
| Tsawg aluminium ferrosilicon | Si75, Al qis dua 0.5 feem pua | Qinghai | 6,400-6,450 ib |
| Tsawg aluminium ferrosilicon | Si75, Al qis dua 0.1 feem pua | Sab hauv Mongolia | 6,700 txog 6,750 |
| Tsawg aluminium ferrosilicon | Si75, Al qis dua 0.5 feem pua | Sab hauv Mongolia | 6,400-6,450 ib |
Ob qhov kev soj ntsuam muaj txiaj ntsig. Kev xa tawm FeSi75 qib zaum saum FeSi72 los ntawm kwv yees qhov sib txawv ntawm cov khoom siv silicon, uas lees paub tias kev lag luam tus nqi silicon ntau dua li tonnage. Nyob rau hauv cov tsev neeg tsawg-aluminium, nruj aluminium los ntawm qis dua 0.5 feem pua mus rau qis dua 0.1 feem pua yog tus nqi kwv yees kwv yees li 300 yuan ib tonne, yog li qis -aluminium cov khoom yuav tsum tsuas yog qhia qhov twg casting defects qhia nws.
Yog vim li cas ib qho pheej yig heev feem ntau tsis pheej yig
Thaum qhov kev thov ferrosilicon poob qis dua qhov ntau ntawm cov khoom tsim nyog, ib qho ntawm plaub qhov kev piav qhia feem ntau siv. Cov qib yuav qis dua li teev, nrog silicon hauv qab qhov tsawg kawg nkaus tshaj tawm. Cov ntsiab lus ntawm aluminium tej zaum yuav siab tshaj qhov qis-aluminium class, uas tshwm sim tom qab li roj porosity thiab ntau dua rejection tus nqi nyob rau hauv nyias- phab ntsa castings. Qhov luaj li cas feem yuav tawm ntawm qhov tshwj xeeb, muaj cov nplua ntau dhau los yog cov pob loj loj uas tsis yaj ntawm qhov xav tau ntxiv. Los yog cov khoom yuav raug muab rau cov nqe lus uas hloov cov khoom thauj, kev pov hwm thiab kev pheej hmoo zoo rau tus neeg yuav khoom. Txhua yam ntawm no tuaj yeem raug kuaj pheej yig: xyuas daim ntawv pov thawj ntawm kev soj ntsuam rau silicon thiab txhuas, tshuaj ntsuam cov qauv rau kev faib loj, thiab ntsuas qhov ntim tau tshaj tawm tawm tsam cov khoom xa tuaj.
Yuav Daim Ntawv Teev Npe rau Foundries thiab Traders
Txhim kho xya yam khoom ua ntej xaj: qib raws li cov ntsiab lus ntawm silicon yam tsawg kawg nkaus, cov chav kawm txhuas, qhov loj me, cov khoom ntim thiab hom, ex- ua haujlwm lossis xa cov hauv paus thiab chaw nres nkoj, cov nqe lus them nqi, thiab cov qauv ntsuas thiab kev tshuaj xyuas siv los daws qhov teeb meem. Khaws ib daim ntawv pov thawj ntawm txhua qhov khoom xa tuaj. Hauv kev siv lub hauv paus, kev tswj xyuas tsis yog tsuas yog cov hlau nws tus kheej nkaus xwb tab sis lub ntsiab lus ntawm qhov sib ntxiv: ferrosilicon ntxiv raws li lub caij nyoog inoculant ntawm txoj cai loj muab cov chill txo thiab graphite refinement xav tau, thaum tib lub alloy ntxiv thaum ntxov thiab sab laug kom ploj ntau dua. Nodularity thiab graphite daim ntawv raug tshuaj xyuas ntawm tus qauv cam khwb cia tiv thaiv ISO 945-1 thiab ASTM A247 cov kab kos siv, uas ua rau cov txiaj ntsig sib piv ntawm kev hloov pauv thiab cov neeg muag khoom.
Cov lus nug nquag
Q:Puas yog FeSi72 pheej yig dua los siv dua FeSi75?
A: Ib tonne ntawm alloy, feem ntau yog. Ib chav tsev ntawm cov khoom siv silicon xa tawm, qhov sib txawv me dua, thiab cov ntsiab lus silicon qis dua txhais tau tias yuav tsum tau ntxiv cov hlau ntau ntxiv, uas coj ntau aluminium thiab carbon rau hauv yaj nrog nws.
Q:Thaum twg tsawg -aluminium ferrosilicon tsim nyog?
A: Qhov twg muaj roj tsis xws luag, pinholes los yog nto porosity teeb meem, piv txwv li nyob rau hauv nyias -phab ntsa los yog siab- nruam castings. Rau cov ntu hnyav nrog cov nyiaj pub dawb machining tus txheej txheem aluminium chav kawm yog ib txwm tsim nyog.
Q:Yuav ua li cas loj ferrosilicon yuav tsum tau siv rau inoculation?
A: Ib qho me me, qhov loj me me tshaj qhov sib ntxiv ntawm silicon, kom cov khoom tawg sai sai thiab faib sib npaug. Cov pob uas ntxhib dhau ua rau qhov tsis sib xws thiab tuaj yeem tso cov khoom seem tsis txaus.
Q:Yuav ua li cas yog cov ntsiab lus ntawm silicon pov thawj ntawm kev xa khoom?
A: Los ntawm kev ua piv txwv ntau thiab tshuaj xyuas nws, nrog rau qhov tshwm sim piv rau qhov tsawg kawg nkaus tshaj tawm rau qib. Khaws ib qho qauv kaw ntawm txhua qhov ntau yog kev coj ua rau kev daws teeb meem.
Q:Kev ntim khoom puas cuam tshuam tus nqi xa khoom?
A: Yog. Tej, ib qho -tonne lub hnab loj thiab 25 kg hnab nqa cov nqi sib txawv thiab kev tiv thaiv ya raws sib txawv, thiab cov ntaub ntawv tshaj tawm hauv ib pob yuav tsum tau kuaj xyuas cov khoom xa tuaj.
Q:Dab tsi ua rau txias hauv grey hlau castings?
A: Tsis txaus silicon thaum lub sij hawm solidification, oxidised yaj, los yog inoculation kauj ruam uas tau faded ua ntej pouring. Kev xaiv qib kom raug tsuas yog ib feem ntawm cov lus teb; lub sij hawm thiab dosing tseem ceeb sib npaug.
