Hauv kev tsim khoom lag luam niaj hnub no, ntau cov txheej txheem ua tsis tau yam tsis muaj qhov chaw kub siab, thiab yuav ua li cas kom muab thiab siv cov cua sov kub siab tau zoo thiab ruaj khov yeej ib txwm yog qhov tseem ceeb ntawm kev lag luam. Kev tshwm sim ntawm silicon carbide ceramic radiation tubes tau coj cov tswv yim tshiab los daws cov teeb meem no thiab ua rau muaj kev hloov pauv tseem ceeb hauv kev lag luam.
1. Dab tsi yogsilicon carbide ceramic radiation tube
Lub raj xa hluav taws xob silicon carbide ceramic, raws li nws lub npe qhia, nws cov khoom tseem ceeb yog silicon carbide. Silicon carbide yog cov khoom siv tshwj xeeb heev nrog qhov nyuaj heev, thib ob tsuas yog pob zeb diamond nyuaj tshaj plaws hauv xwm. Tom qab ua rau hauv cov khoom siv ceramic, nws muaj ntau yam khoom zoo heev, thiab lub raj xa hluav taws xob tau tsim tshwj xeeb ua lub cuab yeej tubular rau kev hloov pauv cua sov hauv qhov chaw kub siab siv cov khoom no. Hauv lwm lo lus, nws zoo li "tus xa khoom cua sov" hauv cov khoom siv kub siab hauv kev lag luam, lub luag haujlwm rau kev xa cua sov mus rau qhov chaw xav tau kom raug thiab zoo.
2, Cov txiaj ntsig ntawm kev ua tau zoo
1. Kev tiv taus kub heev: Cov khoom siv hlau feem ntau yooj yim mos, deformed, thiab txawm tias hlawv tawm ntawm qhov kub siab. Tab sis silicon carbide ceramic radiation tubes tuaj yeem yooj yim daws cov teeb meem kub siab, nrog rau qhov kub ua haujlwm zoo txog li 1350 ℃. Txawm tias nyob rau ntawm qhov kub siab, lawv tseem tuaj yeem tswj tau cov khoom zoo thiab yuav tsis yooj yim deform lossis puas tsuaj. Qhov no ua kom ntseeg tau tias nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv kev tsim khoom lag luam kub siab, muab kev pabcuam cua sov tas mus li thiab txhim khu kev qha rau kev tsim khoom.
2. Kev ruaj khov zoo heev: Hauv kev tsim khoom lag luam, qhov kub feem ntau hloov pauv. Cov coefficient thermal expansion ntawm silicon carbide ceramic radiation tubes yog me heev, ua rau lawv tsis tshua muaj kev ntxhov siab thermal vim yog qhov kub hloov pauv thiab ua kom pom kev ruaj khov thermal shock zoo. Qhov no txhais tau tias nws tuaj yeem hloov pauv ntau zaus hauv qhov chaw txias thiab kub heev yam tsis muaj teeb meem xws li tawg lossis puas tsuaj, nrog lub neej ua haujlwm ntev, txo cov nqi ntawm kev saib xyuas thiab hloov khoom siv.
3, Cov Ntawv Thov
1. Kev lag luam hlau metallurgy: Yuav tsum tswj qhov kub kom raug hauv kev smelting, kev kho cua sov thiab lwm yam txheej txheem ntawm hlau. Silicon carbide ceramic radiation raj tuaj yeem muab cua sov ruaj khov rau cov txheej txheem kub siab no, pab cov tuam txhab hlau txhim kho kev ua haujlwm zoo thiab cov khoom zoo, thaum tseem txo kev siv hluav taws xob.
2. Kev sib xyaw hlau uas tsis yog ferrous: Cov txheej txheem sib xyaw ntawm cov hlau uas tsis yog ferrous xws li txhuas thiab tooj liab kuj vam khom rau qhov kub siab. Cov raj xa hluav taws xob silicon carbide ceramic ua lub luag haujlwm tseem ceeb hauv cov cub tawg hlau uas tsis yog ferrous vim lawv qhov kev ua tau zoo heev, ua kom ntseeg tau tias cov txheej txheem sib xyaw ua tiav.
3. Kev lag luam khoom siv hauv tsev: Piv txwv li, kev hlawv cov khoom siv ceramic yuav tsum tau ua nyob rau hauv qhov cub kub siab. Cov raj hluav taws xob ceramic silicon carbide tuaj yeem muab cov cua sov sib npaug thiab ruaj khov rau qhov cub, uas pab txhim kho qhov zoo ntawm kev hlawv cov khoom siv ceramic, luv lub voj voog hlawv, thiab ua kom muaj txiaj ntsig zoo dua.
Cov raj xa hluav taws xob silicon carbide ceramic tau ua pov thawj tias muaj txiaj ntsig zoo thiab muaj peev xwm hauv kev lag luam kub siab vim lawv ua tau zoo heev. Nrog rau kev nce qib thiab kev txhim kho ntawm thev naus laus zis, nws ntseeg tias nws yuav siv dav hauv yav tom ntej, coj kev yooj yim dua thiab cov txiaj ntsig rau kev tsim khoom lag luam, thiab txhawb kev txhim kho tas mus li ntawm ntau yam kev lag luam cuam tshuam.
