Niaj hnub no niaj hnub nrhiav kev ua haujlwm siab dua- cov hlau cam khwb cia hlau (tshwj xeeb yog cov hlau nplaum thiab siab-kawg grey cam khwb cia hlau), kev kho calcium tau dhau los ua cov txheej txheem tseem ceeb rau kev txhim kho cov khoom siv ductility, purity, thiab cov txheej txheem ntau lawm stability. Tau ntsib nrog ob yam tseem ceeb ntawmcalcium silicon alloyNtxiv rau- cov khoom siv thaiv cov khoom siv niaj hnub thiab cov hlau niaj hnub cored- cov thawj coj hauv tsev feem ntau ntsib qhov kev xaiv nyuaj: qhov twg yog tus nqi ntau dua - zoo?
Ua ntej, peb yuav tsum nkag siab qhov sib txawv ntawm ob qho tib si, uas txiav txim siab qhov sib txawv hauv lawv cov nqi tsim.
Calcium silicon block alloys:Ib txwm siv lub cev. Ntxiv rau ladles lossis furnaces manually los yog mechanically, cia siab rau ntuj dissolution thiab diffusion. Tus nqi tseem ceeb nyob hauv tus nqi ntawm cov khoom siv.
Calcium silicon cored hlau: Composite txheej txheem khoom.CaSi alloy hmoovyog qhwv nyob rau hauv ib tug nruam steel sawb thiab precisely txhaj rau hauv lub molten hlau ntawm ib tug tswj ceev thiab qhov tob siv ib tug hlau feeder. Tus nqi tseem ceeb nyob hauv qhov kev daws teeb meem ntawm "khoom + khoom + txheej txheem".
Tsuas yog muab piv rau "tus nqi ib tuj ntawm calcium" yog lus dag. Tus nqi tiag tiag- kev tshuaj xyuas cov txiaj ntsig yuav tsum yog raws li "tus nqi zoo ntawm calcium," uas yog tag nrho cov nqi ntawm txhua chav tsev ntawm calcium uas thaum kawg absorbed los ntawm cov hlau molten thiab tsim cov nyhuv metallurgical.
Hauv - sib piv qhov tob ntawm cov qauv tsim nqi
| Nqi thiab txiaj ntsig Dimensions | Calcium silicon bulk alloy | Calcium silicon cored hlau | Kev tsom xam thiab kev cuam tshuam rau cov txiaj ntsig kev lag luam |
|---|---|---|---|
| 1. Tus nqi yuav khoom | Tsawg (tus nqi alloy nkaus xwb) | Siab dua(tus nqi ntawm alloy ua rau hauv hlau pas nrig) | Tus Nqi Pom Zoo:Thaiv alloys zoo li pheej yig dua. |
| 2. Calcium Yield | Tsawg (10% -25%)raug huab cua thiab slag, hnyav oxidation thiab hlawv -tawm. | Siab (25% -40% lossis siab dua)Sib sib zog nqus faus nyob rau hauv molten hlau, tiv thaiv cov tshuaj tiv thaiv, tsawg heev poob. | Core Difference:Cored hlau siv ntau "them calcium" los ua cov hlau molten. Piv txwv tias lub hom phiaj calcium ntxiv yog tib yam, qhov tseeb noj ntawm cored hlau tuaj yeem txo los ntawm 30% -50%. |
| 3. Cov nqi ua haujlwm thiab kev ua haujlwm | Siabxav tau qhov hnyav, tuav, thiab tawm tswv yim; tso siab rau kev ua haujlwm ntawm kev ua haujlwm; qeeb ceev; ib puag ncig tsis zoo (fumes). | Tus nqi qis.Automated xaim feeder ua haujlwm, ib qho - nyem ua tiav tom qab qhov kev teeb tsa, nrawm nrawm, rov tsim tau zoo, ib puag ncig huv. | Cored hlau txuag kev ua haujlwm,nce lub sij hawm voj voog ntau lawm, thiab txo qhov kev hloov pauv zoo los ntawm kev ua haujlwm sib txawv. |
| 4. Qhov zoo thiab cov khoom seem | Kev hloov pauv lojnyob rau hauv yield ua rau uncontrollable calcium kev kho cov teebmeem, yooj yim ua rau tsis zoo inoculation, tsis zoo graphite morphology, shrinkage porosity, thiab muaj peev xwm seem seem. | Stable, zoo heev,thiab kev tswj xyuas meej kom ua tiav cov txiaj ntsig zoo ib yam rau txhua lub ladle ntawm cov hlau molten, txhim kho graphite spheroidization tus nqi, txo qhov tsis xws luag, txo cov seem seem, thiab txo cov neeg thov kev pheej hmoo. | Qhov no yog qhov loj tshaj plaws zais nqi txuag.Qhov txiaj ntsig ntawm kev txo cov khoom seem ntawm 1% feem ntau nyob deb tshaj qhov sib txawv ntawm cov khoom siv. |
| 5. Cov cuab yeej siv peev | Tsis muaj los yog tsawg heev(cov cuab yeej yooj yim). | Yuav tsum tau peev nyob rau hauv ib tug hlau feeder(ib -lub sij hawm siv peev). | Lub ntsiab teeb meem rau cored hlau ntau lawm. Txawm li cas los xij, tom qab amortizing cov cuab yeej depreciation tshaj cov khoom siv niaj hnub, nws cov nqi feem ntau them los ntawm kev txhim kho kom zoo thiab txuag cov khoom siv. |
Cov mis yooj yim rau kev suav "cov nqi calcium zoo":
Cov nqi calcium zoo=(Tag nrho cov khoom siv + nqi khiav lag luam + Tus nqi tsis zoo) / Tag nrho cov calcium uas zoo absorbed los ntawm molten hlau
Raws li cov qauv no, vim qhov txiaj ntsig tseem ceeb ntawm cored hlau nyob rau hauv tus lej (tag nrho cov calcium uas zoo) thiab kev txo qis hauv kev khiav hauj lwm thiab cov nqi tsis zoo hauv tus lej, nws cov nqi calcium kawg yuav qis dua li ntawm cov hlau thaiv.
Daim Ntawv Thov Scenarios thiab Kev Txiav Txim Siab Tsob Ntoo
Xav txog calcium silicon cored hlau yog tias koj:
Tsim kom muaj siab -kev ua tau zoo ntawm cov hlau hlau castings (xws li cua turbine castings, automotive chassis, thiab core engine Cheebtsam).
Cov khoom muaj tus nqi ntxiv thiab cov kev cai nruj rau qhov zoo sib xws thiab cov khoom siv kho tshuab (tshwj xeeb tshaj yog elongation thiab cuam tshuam toughness).
Tau ntsib cov neeg siv khoom zoo soj ntsuam cov qauv nruj lossis sab hauv cov nqi siab.
Pursuing automation, standardization, thiab traceability nyob rau hauv cov txheej txheem ntau lawm.
Loj molten hlau ua muaj peev xwm txaus rau amortize cov cuab yeej peev hauv cov hlau feeder.
Thaiv alloys tseem yuav yog ib qho kev xaiv yog tias koj:
tsim cov grey cam khwb cia hlau zoo tib yam lossis cov khoom siv hlau uas tsis tshua muaj, thiab muaj kev ua siab ntev rau kev ua haujlwm hloov pauv.
tsim rau ntawm ib qho me me nrog cov khoom siv tsawg heev, ua rau nws nyuaj rau rov qab koj cov cuab yeej cuab tam peev.
tsuas yog ua tsis raws cai, qee zaus kev kho calcium ntxiv.
Raws li tus kws tshaj lij kev lag luam muab ob qho tib si siab - zoo casi alloy lumps thiab casi cored xov hlau nyob rau hauv ntau yam specifications, [AON Metals] tsis muaj lub hom phiaj los txhawb ib yam khoom tshwj xeeb. Peb nkag siab tias tsis muaj cov khoom "zoo tshaj", tsuas yog "tsim" kev daws teeb meem. Peb pab pawg kws tshaj lij tuaj yeem pab koj hauv kev tshuaj xyuas koj qhov xwm txheej tam sim no, ua cov nqi simulation, thiab muab cov qauv kev txhawb nqa los pab koj txiav txim siab zoo tshaj plaws thiab muaj txiaj ntsig zoo rau koj lub Hoobkas raws li cov ntaub ntawv thiab qhov tseeb.
