Hauv kev lag luam kub siab thiab kev thauj mus los,silicon carbide (SiC) rollersyog cov khoom siv ua tau zoo tshaj plaws uas ua tau zoo dua li cov alumina ceramic thiab alloy rollers ib txwm muaj. Ua los ntawm kev tiv taus cua sov heev, kev ntxhov siab ntawm lub tshuab thiab cov cua sov corrosive, lawv muaj kev ruaj khov zoo, kev ruaj khov ntawm qhov loj me thiab kev tiv thaiv kev hnav, ua rau lawv yog cov khoom tseem ceeb rau cov kilns niaj hnub thiab cov kab ntau lawm. Rau cov tuam txhab tsim khoom thoob ntiaj teb uas tab tom nrhiav kev txiav lub sijhawm tsis ua haujlwm, txo cov nqi kho thiab txhim kho cov khoom zoo, SiC rollers yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm kub siab.
Cov menyuam roj hmab silicon carbide siv dav thoob plaws cov lag luam tseem ceeb uas muaj kev thov siab. Feem ntau, lawv pab rau kev lag luam ceramic, txhawb nqa cov vuas vov, cov khoom siv huv thiab cov khoom siv hauv rooj tog hauv thaj chaw hlawv hluav taws kub ntawm 1350 ℃ -1450 ℃, nyob ncaj tsis muaj khoov lossis ua qias tuaj kom txo cov khoom tsis zoo. Lawv kuj tseem ceeb hauv kev tsim iav, thauj cov iav tiaj tus thiab cov khoom siv iav kom du thaum lub sijhawm annealing thiab tsim kom tiv thaiv khawb. Cov ntawv thov tseem ceeb ntxiv suav nrog kev kho cua sov metallurgy rau cov khoom hnyav thauj khoom, thiab lub zog tshiab rau lithium-ion roj teeb electrode thiab hluav taws xob ceramic sintering, ua tsaug rau lawv cov khoom tsis ua qias tuaj, cov khoom siv ntshiab.
Muaj ob qib SiC roller uas yog tus qauv lag luam nrog cov tub ntxhais sib txawv: recrystallized SiC (RSiC) thiab reaction-bonded SiC (RBSiC), txhua tus tau tsim los rau cov xwm txheej ua haujlwm tshwj xeeb.
Cov menyuam SiC recrystallized yog ua los ntawm kev kub siab sintering tsis muaj theem khi, xa cov qauv SiC ntshiab. Lawv muaj qhov tiv taus kub ntev ultra-siab txog li 1600 ℃, tiv taus thermal shock zoo heev thiab xoom impurity contamination, zoo meej rau cov khoom siv ceramics siab, cov ntaub ntawv hluav taws xob thiab cov ntawv thov zog tshiab qhov twg purity thiab kev kam rau siab kub heev yog qhov tseem ceeb. Lawv muaj peev xwm thauj khoom tsawg dua me ntsis tab sis tsis muaj qhov kub siab ruaj khov.
Cov menyuam SiC uas muaj Reaction-Bonded yog tsim los ntawm cov khoom me me uas muaj silicon binding phase, uas muaj qhov ceev dua, muaj zog dua thiab muaj kev ua haujlwm zoo dua rau kev thauj khoom hnyav. Tsim los siv tau ntev ntawm 1350 ℃ -1450 ℃, qhov kub thiab txias feem ntau ntawm lub cub tawg, lawv pheej yig thiab tiv taus kev hnav, ua rau lawv yog qhov xaiv zoo tshaj plaws rau cov vuas ceramic txhua hnub, cov iav txheem thiab cov kab ntau lawm metallurgy.
Ob hom SiC rollers muaj cov txiaj ntsig tseem ceeb: tsawg kawg nkaus qhov kub thiab txias deformation, muaj zog oxidation thiab corrosion tsis kam, thiab lub neej ua haujlwm ntev dua li cov rollers ib txwm muaj, txo cov nqi hloov pauv thiab cov nqi zog ua haujlwm ntau heev.
Peb muab cov kev pabcuam SiC roller uas ua raws li koj xav tau. Peb pab neeg pab koj xaiv cov qib recrystallized thiab reaction-bonded raws li qhov kub ua haujlwm, qhov hnyav thiab peev nyiaj, tom qab ntawd kho qhov loj me tseem ceeb: txoj kab uas hla sab nraud/sab hauv, tag nrho thiab qhov ntev zoo, ntxiv rau kev ua kom raug xws li necking, slotting thiab stepped ends kom haum rau koj lub cub tawg zoo meej.
Thaum kev tsim khoom lag luam hloov mus rau cov txheej txheem kub siab dua, cov menyuam silicon carbide tseem yog qhov kev daws teeb meem rau kev tsim khoom ruaj khov thiab pheej yig. Nrog kev ua tau zoo txhim khu kev qha thiab kev hloov kho tau yooj yim, lawv pab ua kom zoo dua kev ua haujlwm thiab txhim kho kev sib tw ntawm cov khoom. Yog tias koj xav tau cov menyuam SiC zoo lossis kev taw qhia kev cai, peb pab neeg kws tshaj lij muab cov khoom siv tag nrho, kev tsim qauv thiab kev txhawb nqa tom qab muag kom tau raws li koj cov kev xav tau kev thauj khoom kub siab.
