Lub ntiaj teb steel kev lag luam, lub pobzeb ntawm infrastructure thiab kev tsim khoom, nyob rau cov khoom siv ntxiv rau txhim kho kev ua haujlwm siab, cov khoom lag luam zoo, thiab ua haujlwm ruaj khov. Ntawm cov ntawv tseem ceeb no,Silicon Carbide (Sic)sawv rau nws qhov tshwj xeeb tawv, thermal conductivity, thiab tshuaj lom neeg ruaj khov. Tshwj xeeb, carbide silicon nrog qhov loj me ntawm 1}}}}}}}}}}} Txoj cai ua tau zoo thiab txhim khu kev qha rau cov neeg thoob ntiaj teb.
Vim li cas 1-10mm loj Silicon Carbide yog qhov tseem ceeb rau kev lag luam steel
Qhov loj me yog kev txiav txim siab txiav txim siab hauv kev txiav txim siab qhov ua tau zoo ntawm SIC hauv kev tsim cov hlau. Qhov 1 {- 10mm ntau yog ua tib zoo faib kom sib npaug rau kev sib npaug ntawm ob qho: ob qho tib si uas tsis yog kev sib ceg hauv cov txheej txheem steelmaking.
Rau cov ntawv thov refractory (piv txwv li, thaj chaw rauv taws, thiab tundust bermal poob siab, ib qho kev sib tw hauv qhov kub-kub yaj. Cov khoom me me (1-5mm) ua li "fillers," Kaw cov nplej ntawm cov nplej loj kom txo porosity thiab tiv thaiv Molten hlau nkag mus. Cov kev kawm tiav no ua kom tiav cov refractory tswj hwm nws cov qauv kev thiab kev ua haujlwm txawm tias tsis ntev los rau qhov kub tsis ntev dhau los 1,600 degree.
Nyob rau hauv steel aloying thiab deoxidation, tus 1-10 hli loj pab tswj cov tshuaj tiv thaiv kev tiv thaiv. Tsis zoo li cov hmoov nplej uas muaj zog uas tuaj yeem oxidize ua ntej lub npe ua ntej, ua kom tshem tawm cov khoom seem Qhov xwm txheej no ncaj qha txhim kho cov hlau tensile lub zog thiab ductility.
Nkag siab 88% Ua Raws Nrog Kev Lag Luam Hlau Hlau
Ua raws li kev lag luam hlau lag luam thoob ntiaj teb tsis yog ib qho kev sib tw ntawm cov qauv phom sij rau cov qauv uas muaj kev sib tw -}} Rau 1-10 hli silicon carbide, 88% ua raws li kev qhia txog kev ua raws cai rau cov qauv hauv qab no:
1. Tshuaj Purity
Ntiaj teb steel ua yuam kev tsawg kawg li Silicon cov ntsiab lus (tsawg dua lossis sib npaug nrog 0.8%) {{4 4 {%) {%) {%) {%) Batches, ua kom nws tsis qhia qhov tsis xws luag (xws li, brittleness, suav nrog) rau hauv cov steel steel.
2. Qhov loj me faib
Norments xws li ASTM C771 Qhia meej tias 1-10 hli Silicon Carbide yuav tsum muaj ntau dua lossis sib npaug {% ua raws li cov khoom siv hluav taws xob tsis sib xws los yog cuam tshuam los ntawm oversized lossis undersized hais.
3. Thermal thiab tshuab ruaj khov
Steelmakaking xav tau cov ntaub ntawv uas walland cyclic cua sov thiab cua txias. Cov qauv zoo li ISO 13765, sim ua silicon carlocide alloy los khaws cov khoom muaj zog tshaj li ntawm cov khoom ntseeg tau muaj kev ntseeg siab nyob rau hauv ib puag ncig.
Ntsiab lus tseem ceeb:88% kev ua raws tsis yog "tus nqi tsis xws" tab sis kev ntsuas ntawm kev sib xws nyob rau hauv cov pob khoom ntau lawm. Txog nruab nrab - rau {{3} high {} Kev ua haujlwm qis dua li ultra}
Cov ntawv thov ntawm 1-10 hli 88% ua txhaum silicon carbide hauv statmaking stathermaking
Qhov no cov carbide qib no yog ntau yam, nrog peb cov ntawv thov tseem ceeb hauv kev lag luam steel:
1. Refractory Linings
Nws yog thawj qhov tseem ceeb hauv Silicon Carractory cib thiab cov khoom siv ua kom tawg nyob rau thaj tsam Bosh, pw hauv qab, thiab tundish mus rau sab nraud. Nws 88% kev ua raws li lub neej sib xws (6 {{4 4}} kev ua haujlwm rau kev kho - ib qho tseem ceeb-txuag tau zoo rau stathermakers.
2. Hlau deoxidation thiab kev sib ntxiv
Raws li deoxidizer, nws reacts nrog yaj oxygen nyob rau hauv molten steel los ua silicon dioxide (sitats li slag thiab yog yooj yim tshem tawm. Raws li ib tug neeg sawv cev ua ke, nws nce cov steel cov ntsiab lus (txog li 1.5% rau kev ua kom muaj kev ua kom muaj kev sib raug zoo heev (ntau dua lossis sib npaug.
3. Lub ntsej muag tawg
Nyob rau hauv nruam camting, 1 {{}} 10mmm silicon carbide yog ntxiv rau kev kho nws lub piscosity yog ntxiv rau kev kho kom haum (qhov tseem ceeb ua rau ntawm cov hlau tsis xws luag). Nws ruaj ruaj ruaj ruaj ruaj ruaj ruaj ruaj ruaj ruaj ruaj khov, txo cov khoom siv tsis zoo los ntawm 15-20% piv rau cov qib tsis raws cai.
Yuav ua li cas xaiv thiab siv tau 88% ua raws li Silicon carbide
Rau cov stathermakers nrhiav kom muaj kev siv cov khoom siv no, xaiv cov kev xaiv nyuaj thiab siv tau yog qhov tseem ceeb. Ntawm no yog ib kauj ruam - ntawm -} kauj ruam qhia:
Txheeb xyuas cov ntawv pov thawj:Thov Daim Ntawv Qhia Cov Lus Qhia (MTR) los ntawm cov neeg muab khoom, lees paub ua raws li ISO 13765} 2 (Refractories) lossis A871 (cov neeg sawv cev a871 Ua kom cov ntaub ntawv qhia tseeb suav nrog cov ntaub ntawv tshwj xeeb ntawm kev coj dawb huv, PSD, thiab thermal stability.
Kuaj me me Batches:Cus lus xeem hauv tsis - ladle tseem ceeb (piv txwv li}
Ntsuas cov khoom sib xws:Muab cov chaw muab khoom nrogISO 9001 Ntawv Pov ThawjThiab hauv {-} lub tsev tswj kev ua haujlwm. Tsis sib xws cov khoom siv sofycing (piv txwv li, siv qis - purity silicon carbide ore) yog ib qho kev ua txhaum cai.
1 {- 10mmm silicon carbide nrog 88% ua raws li cov khoom siv steelming, muab ib qho kev ua haujlwm ntawm lub ntiaj teb Nws lub luag haujlwm hauv cov ntaub regractory, deoxidation, thiab slag txias ncaj qha cuam tshuam cov hlau zoo thiab ntau lawm ua tau zoo. Los ntawm kev nkag siab txog kev ua raws cai, kev siv cov ntawv thov, thiab xaiv cov kev ua tau zoo tshaj plaws rau cov nqi ntawm cov khoom lag luam tseem ceeb thaum npaj rau kev lag luam yav tom ntej.
