Qhov chaw ua av cibYog qhov tseem ceeb ua ke tiv thaiv siv hauv cov hlau metallurgical engineering rau sab nraud txhim kho hauv cov hlau. Nws pab cov steel nplawm los ntawm qab-}}}} tshuab roj, muab siab thermal stability thiab yaig starstance. Raws li ntev - kav, zog {{4} {{{{5} {tsawg} kev txo khoom,Qhov chaw ua av cibyog feem ntau tsim los ntawm cov ntaub ntawv xws li Corundum, Corundum spinel, thiab chromite- corundum. Ntawm cov no, Corundum Spinel permeable Clocks tau hloov pauv cov khoom siv chromite - Corundum cov khoom vim lawv lub corrosion distance. Piv txwv li, aQhov chaw ua paCov khoom tsim los ntawm Luoyang Jinai tuam txhab ua tiav lub neej pabcuam ntawm 30 txog rau ib lub tshuab sib cav, ua rau muaj kev sib cav sib ceg ntawm 5 lab YUAN.
Qhov chaw ua av cibCov qauv tau faib rau hauv peb hom: dispersed, ncaj -} los ntawm kev taw qhia, thiab slit -}}}}}}}}}}}}}}}}}}}}} kev qhia. Lub slit - Kev Qhia Txog Hom tau dhau los ua cov ntsiab lus vim nws lub neej muaj kev pabcuam siab ntev. Cov teeb meem tseem ceeb ntawm kev puas tsuaj suav nrog thermal kev ntxhov siab, kev siv tshuab yision, thiab hlau slag infiltration.
Thaum ntxiv ntawm croo₃ tuaj yeem txhim kho impermability,Qhov chaw ua av cibnqa txoj kev pheej hmoo ntawm CRT kev muaj kuab paug. Kev Tshawb Fawb Tam Sim No thiab Kev Tsim Kho Kev Tshawb Xyuas ntawm daim ntawv thov ntawm Nanomaterials, ntawm kev xaiv ntawm kev ua kom haum, thiab kev ua haujlwm zoo ntawm cov kab sib ntxiv. Hom tshiab ntawmQhov chaw ua paKev sib xyaw Nano calcium carbonate tau tiav chromium - dawb ntau lawm, sib txuas} pore nruj nrog kev nruj dua. Tsis tas li ntawd, kev saws los ntawm cov qauv qauv tsim rau lub rooj zaum cib, nrog rau cais cov thev naus laus zis, tau txo nws tus nqi yaig los ntawm ntau dua 0.5 hli rau ib qho kub.
Kev Ua Haujlwm Siv: Slag Kuj
Txhawm rau txhim kho lub slag tiv taus thiab hlau nkag ntawm alumina spinelQhov chaw ua pa, Cr₂o₃ lossis chromium -} muaj cov tebchaw feem ntau ntxiv. Cr₂o₃ muab cov qauv siv lead ua ib yam li - al₂o₃. Nws cov kev sib ntxiv tsis tsuas yog txhim kho kev swb ntawm cov khoom tab sis kuj nce lub kaum hlua ntub ntawm lub cib thiab hlau Molten. Qhov no ua rau txo cov blockage tshwm sim los ntawm hlau interiltration.
Aluminium - chromium cov tshuaj, hmoov zoo li roj ntsha, nrog rau cov iav ua kua uas twb muaj lawm thaum sib chwv nrog cov txheej txheem statmaking. Theem no hinders lub slag tus corrosion ntawm lubQhov CibCov. Ib txhij, nws nqus hlau oxide (Feo) thiab magnesium thiab kev sib sau ntom ntom nti ntawm lub cib, yog li txhim kho nws cov swb ntug dej hiav txwv.
Txawm li cas los xij, ntxiv croo₃ rau cov khoom ua ib puag ncig kev pheej hmoo, raws li cr³n tuaj yeem yog oxidized rau lom cr a thaum high- kub tua lossis kev pabcuam kub. Yog li ntawd, kom txuag tau lub zog thiab tiv thaiv ib puag ncig, kev siv cr₂o₃ yuav tsum muaj tsawg. Lub hom phiaj tshawb fawb yog kom ua tiav qhov siab sib piv siab-}}}}}}}}}}
Thermal poob siab tsis kam
Lub Koom Haum Me Nyuam YausQhov chaw ua payog thermal poob siab puas tsuaj. Raws li steelmaking kub tsis tu ncua nce ntxiv, qhov tseeb kub gradient ntawm lub ntsej muag kub ntawm lubQhov chaw ua paThaum lub sijhawm ua haujlwm thiab nws cov cheeb tsam txias thaum lub sijhawm xav tau kev xav tsis tshua muaj cua sov kev poob siab los ntawm cov khoom. Qhia txog theem spinel rau hauv cov ntawv sib xyaw ua ke tuaj yeem txhim kho lub thermal poob siab tsis zoo ntawm cov cib ntau.
Ib qho ntxiv, oxides lossis tsis -} oxide ntxiv rauQhov chaw ua paDaim ntawv teeb tsa theem theem nrog cov aggregate ntawm qhov kub. Qhov no nce lub cib lub siab- lub zog (lossis permeability, yog tias muaj kev ruaj ntseg), thiab txhim kho kom tiv thaiv slag yaig hauv tsev. Ua raws li siab - kub kev kho, tag nrho cov kev ua tau zoo tshaj plaws ntawm cov cib yog tsim kho kom zoo, ntsib txhua qhov kev pabcuam xav tau.
