Kev piav qhia
Ntshiab silicon carbide abrasive yog cov xim tsis muaj xim thiab pob tshab. Muaj silicon carbide tshwm nyob rau hauv lub teeb daj, ntsuab, xiav lossis txawm dub vim muaj ntau hom thiab cov ntsiab lus ntawm impurities, thiab nws cov pob tshab txawv nrog nws cov purity. Cov qauv siv lead ua ntawm silicon carbide muab faib ua hexagonal lossis rhombohedral -SiC thiab cubic -SiC (hu ua cubic silicon carbide). -SiC muaj ntau qhov sib txawv vim qhov sib txawv sib txawv ntawm cov pa roj carbon thiab silicon atoms hauv nws cov qauv siv lead ua, thiab ntau dua 70 hom tau pom. -SiC hloov mus rau -SiC saum 2100 degree.
Cov txheej txheem kev lag luam ntawm silicon carbide yog siv cov khoom zoo quartz xuab zeb thiab roj av coke los ua kom nws nyob rau hauv lub qhov cub ua haujlwm. Cov silicon carbide blocks tau ua rau hauv cov khoom ntawm ntau qhov ntau thiab tsawg los ntawm kev sib tsoo, kua qaub thiab alkali ntxuav, sib nqus sib nqus thiab tshuaj ntsuam lossis dej sib cais.

Vim nws cov ntsiab lus tsis tshua muaj ntuj, silicon carbide yog tib neeg tsim. Ib txoj hauv kev yog sib tov quartz xuab zeb nrog coke, siv cov silica thiab roj av coke, ntxiv ntsev thiab ntoo chips, muab tso rau hauv lub qhov cub hluav taws xob, cua sov rau qhov kub txog li 2000 degree, thiab tau txais cov hmoov silicon carbide tom qab ntau yam tshuaj. txheej txheem.
Silicon carbide abrasive (SiC) tau dhau los ua abrasive tseem ceeb vim nws qhov nyuaj heev, tab sis nws daim ntawv thov ntau tshaj li cov abrasives. Piv txwv li, nws qhov kub thiab txias tsis kam thiab thermal conductivity ua rau nws yog ib qho ntawm thawj qhov kev xaiv cov khoom siv rooj tog rau qhov cub los yog shuttle kilns. Nws cov hluav taws xob conductivity ua rau nws yog ib qho tseem ceeb ntawm hluav taws xob cua sov.
Txhawm rau npaj SiC cov khoom, koj yuav tsum xub npaj SiC smelting blocks [los yog: SiC granules. Vim tias lawv muaj C thiab nyuaj heev, SiC granules tau raug hu ua: emery. Tab sis ceev faj: nws muaj qhov sib txawv ntawm cov emery (garnet). Hauv kev tsim khoom, SiC smelting blocks feem ntau siv quartz, roj av coke, thiab lwm yam raws li cov khoom siv raw, cov khoom siv rov ua dua tshiab thiab cov ntaub ntawv pov tseg, thiab tau npaj los ntawm kev sib tsoo thiab lwm yam txheej txheem rau hauv cov khoom siv rau hauv cov khoom siv hluav taws xob uas tsim nyog thiab qhov loj me me (kom kho. Lub permeability ntawm lub cub tawg cov ntaub ntawv, ib tug tsim nyog tus nqi yuav tsum tau ntxiv (los ntawm sawdust, thaum npaj ntsuab silicon carbide, ib tug tsim nyog tus nqi ntawm ntsev yog ntxiv) thiab npaj nyob rau hauv high kub. kub yog ib qho tshwj xeeb silicon carbide hluav taws xob rauv.
Nws cov qauv muaj lub cub tawg hauv qab, ib phab ntsa kawg nrog cov electrodes nyob rau sab hauv, ib sab phab ntsa tshem tau, thiab lub cub hluav taws xob lub cev (lub npe tag nrho: lub zog hluav taws xob cua sov hauv nruab nrab ntawm lub qhov cub hluav taws xob, feem ntau Graphite hmoov lossis roj av coke yog ntsia rau hauv nruab nrab ntawm tus nqi raws li ib tug tej yam zoo li thiab loj, feem ntau yog ncig los yog rectangular.Nws ob kawg yog txuas nrog electrodes) thiab lwm yam khoom. Txoj kev tua hluav taws siv hauv qhov cub hluav taws xob no feem ntau hu ua: faus hmoov firing. Cov cua sov pib sai li sai tau thaum lub tshuab hluav taws xob. Qhov kub ntawm lub cub tawg yog li ntawm 2500 degree lossis siab dua (2600 ~ 2700 degree). SiC pib ua ke thaum tus nqi nce mus txog 1450 degree (tab sis SiC feem ntau yog tsim los ntawm ntau dua lossis sib npaug rau 1800 degree), thiab CO raug tso tawm.
Txawm li cas los xij, SiC yuav decompose ntawm ntau dua lossis sib npaug li 2600 degree, tab sis cov decomposed Si yuav hnov mob nrog C hauv tus nqi los tsim SiC. Txhua pawg ntawm cov hluav taws xob rauv yog nruab nrog ib txheej ntawm transformers, tab sis tsuas yog ib qho hluav taws xob rauv yog powered thaum lub sij hawm tsim khoom nyob rau hauv thiaj li yuav kho qhov voltage raws li cov hluav taws xob load yam ntxwv los yeej muaj zog tas li. Lub tshuab hluav taws xob muaj hluav taws xob siab yuav tsum tau ua kom sov li 24 teev. Tom qab hluav taws xob tawm, cov tshuaj tiv thaiv los tsim SiC yog qhov pib ua tiav. Tom qab lub sijhawm txias, cov phab ntsa sab nraud tuaj yeem raug tshem tawm, thiab tom qab ntawd tus nqi yuav maj mam muab tawm.
