High Cov pa roj carnel silicon lumps

Nyob rau hauv cov pa roj carbon silicon liumns, si yog ib qho ntawm cov ntsiab lus silicon thiab cov ntau zaus yuav nyob ib puag ncig 60%- 80%. C, raws li lwm qhov tseem ceeb tseem ceeb, muaj cov ntsiab lus tseem ceeb, uas tuaj yeem ncav cuag 10%- 30%. Cov feem ntau yog nyob ntawm lub hom phiaj ntawm cov khoom lag luam thiab cov txheej txheem ntau lawm. Cov ntsiab lus siab ntawm carbon muab cov khoom siv qee yam tshwj xeeb.

Ntxiv rau cov pa roj carbon thiab silicon,High Fiber Silicqog tej zaum kuj tseem muaj ib qho me me ntawm cov neeg tawg nkoj xws li FE, AL, thiab CA. Cov ntsiab lus ntawm cov neeg uas tawg feem ntau yog tsawg, feem ntau nyob ib ncig ntawm 1% - 5}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. Piv txwv li, cov hlau yuav cuam tshuam rau lub magnetism thiab ua haujlwm ntawm cov khoom, thiab al tuaj yeem cuam tshuam nws cov tshuaj lom neeg. Thaum lub sijhawm cov txheej txheem tsim khoom, cov ntsiab lus ntawm cov neeg uas tsis sib xws yuav tsum tau nruj me ntsis kom tau raws li cov kev xav tau ntawm cov khoom siv sib txawv.

Txo tus neeg sawv cev thiab carburizer nyob rau hauv cov txheej txheem statmaking

Hauv cov txheej txheem statmaking, nws tuaj yeem siv los ua tus neeg sawv cev txo qis, thiab c hauv nws cov pa roj oxygen hauv cov hlau thiab ua si adeoxidationlub luag haujlwm. Nyob rau tib lub sijhawm, vim nws cov ntsiab lus carbon siab, nws kuj tseem tuaj yeem siv ua cov ntsiab lus carburizer kom tau raws li cov ntsiab lus carbon rau cov ntsiab lus carbon monoxide.

Cov ntaub ntawv tso rau hauv inoculants thiab spheroidizers hauv kev lag luam foundry

Hauv kev lag luam kev lag luam, nws tuaj yeem siv los ua cov inoculant los txhawb cov khoom siv tshuab, txhim kho cov kab nrib pleb, thiab txo cov kab nrib pleb, thiab txo cov kab nrib pleb, thiab txo cov kab nrib pleb, thiab txo cov kab nrib hlau, thiab lwm yam tsis xws luag ntawm cov castings. Tsis tas li ntawd, hauv kev tsim cov hlau uas muaj ntau lawm, nws tuaj yeem siv ua cov khoom siv cov khoom siv rau spheroidizers. Thaum siv ua ke nrog spheroidizers, nws pab tswj cov txiaj ntsig zoo, txhim kho cov pob morphology thiab faib cov khoom lag luam zoo nkauj.

Raws li cov ntaub ntawv raw lossis cov cab kuj catalyst nyob rau hauv qee cov tshuaj lom neeg

Hauv qee cov txheej txheem kev siv tshuaj ntau lawm, Si thiab C thiab C hauv HC sillicon tuaj yeem koom nrog cov khoom siv tshuaj lom neeg thiab siv cov ntaub ntawv raw los ua hluavtaws. Piv txwv li, hauv kev tsim tawm qee cov organosilicon tebchaw, SI tuaj yeem siv ua qhov pib cov khoom siv rau cov tshuaj tiv thaiv. Nyob rau tib lub sijhawm, vim nws muaj qee qhov chaw tshwj xeeb sab nraud, nws kuj tseem tuaj yeem siv cov khoom siv hluav taws xob, thiab txhawb nqa cov tshuaj tua kab mob.

Raws li kev ntxiv rau cov ntaub ntawv refractory

Nws tuaj yeem siv los ua cov khoom siv ntxiv rau cov khoom siv refactory los txhim kho kev ua haujlwm ntawm cov ntaub ntawv refractory. Lub xub ntiag ntawm C tuaj yeem txhim kho lub saws erosion tsis kam thiab thermal poob siab ntawm cov khoom siv hluav taws xob kub siab ntawm cov khoom siv kub. Nyob rau hauv high - kub muaj cov khoom siv hluav taws xob, txo cov khoom siv reflicting, nce ntau ntau yam kev cuam tshuam los ntawm kev puas tsuaj rau cov khoom siv refactory.

Cov pa roj carbon silbon muaj ntau yam ntawm cov khoom uas ua rau nws muaj txiaj ntsig zoo hauv cov txheej txheem:

Deagidation & Carburization:

Ib qho ntawm thawj qhov txiaj ntsig ntawm cov pa roj carbon ntau dua yog nws lub peev xwm ua cov haujlwm dual hauv metallurgy. Silicon ua raws li lub haib deoxidizer, reacting nrog oxygen nyob rau silicon dioxide (sitats), uas xeb mus rau saum npoo ua ke, txo cov olide, txo cov olide suav thiab txhim kho cov roj purity. Lub caij no, cov pa roj carburization, nce cov ntsiab lus carbon monoxide ntawm cov hlau los txhim kho hardness, lub zog, thiab hnav tsis kam.

Nqi -}} Zoo Alloy Ntxiv:

Piv rau kev siv cais silicon thiab cov pa roj carbon, cov pa roj carbon ntau, muaj cov pa roj caricon muaj tus nqi {}} kev daws teeb meem zoo los ntawm kev sib txuas ntawm ob qho tib si. Qhov no txo ​​cov khoom siv tuav, chaw cia khoom, thiab cov nqi ua, thaum ua kom muaj kev faib cov khoom sib xyaw ntawm cov hlau molten.

Txhim Kho Lub Casting Kev Ua Haujlwm:

Hauv kev siv cov ntawv thov, silicon carbon alloy txhim kho cov hlau, ua kom nws yooj yim los sau cov duab ua ke thiab cov ntsiab lus zoo. Nws kuj tseem pab kom txo porosity thiab shrinkage nyob rau hauv castings, txhim kho lawv cov khoom siv mechanical thiab cov qauv kev ntseeg.

Tswj cov qib impurity:

Siab - Zoo HC silicon undergoes nyuaj heev los soj ntsuam cov txiv leej faj, phosphorus, thiab lwm yam impurities. Qhov no yog qhov tseem ceeb rau kev siv hauv high- qib steel thiab cam khwb cia hlau ntau lawm, qhov chaw impurities tuaj yeem haum cov kev ua tau zoo.
