Cov teeb meem tshwm sim hauv kev siv cov ntaub ntawv tundish refractory, qee qhov teeb meem zoo ntawm cov ntaub ntawv lawv tus kheej, thiab qee qhov cuam tshuam nrog kev tsim kho ntawm qhov chaw, yuav tsum tau ua tib zoo saib xyuas thiab tshuaj xyuas. Yog li ua raws li kuv thiab nrhiav cov teeb meem thiab kev daws teeb meem ntawm tundish refractory configuration.
Cov khoom siv qhuav / Tsis tshua muaj zog qhuav Khoom
Tom qab kev co thiab ci, cov khoom qhuav feem ntau yuav tsis muaj zog lossis tsis muaj zog, uas yuav yooj yim ua rau lub hnab ntim thiab cuam tshuam rau cov ntaub ntawv ntawm kev nruam casting. Tom qab kev soj ntsuam mus sij hawm ntev thiab kev soj ntsuam, nws tau txiav txim siab tias cov laj thawj tseem ceeb ntawm cov khoom tsis muaj zog lossis cov khoom qhuav yog raws li hauv qab no:
(1) cov teeb meem ci: cov khoom siv tundish roasting siv nyob rau hauv cov nroj tsuag steel yog cov roj roaster, uas yuav ua rau ntau cov tar hauv cov raj xa dej los yog kev puas tsuaj rau lub qhov cub tom qab siv mus ntev, ua rau cov nyhuv ci hauv zos tsis zoo thiab tsis muaj lossis tsis zoo. qis siv.
(2) cov khoom qhuav damp ingress: cov khoom qhuav yog tsim los ntawm 70% hais thiab 30% hmoov zoo. Cov hmoov zoo muaj magnesia xuab zeb thiab khi tus neeg sawv cev. Vim muaj qhov tshwj xeeb saum npoo av, hmoov zoo tau yooj yim nqus dej thiab ntub dej.
Kev daws: Ua ntej ntawm tag nrho cov, nws yog ib qho tsim nyog los xyuas kom meej qhov ci ntawm lub roaster, tsis tu ncua ntxuav cov kav dej, tshem tawm cov tar thiab plua plav, thiab hloov cov hluav taws kub kom raug; thib ob, nws yog ib qho tsim nyog los xyuas kom meej tias cov ntaub ntawv qhuav qhuav thiab sib tov sib npaug.
Turbulence Floats
Qee zaum, cov turbulizer yuav dhau los ntawm ntuj txiag teb tsaus ntawm cov kua hlau nyob rau hauv cov txheej txheem ntawm ntau lub cub tawg nruam casting, uas tsis tuaj yeem stabilizing cov hlau ntws thiab tiv thaiv qhov cuam tshuam cheeb tsam, uas tsis zoo rau qhov zoo thiab kev nyab xeeb ntawm cov kua hlau. .
Kev daws: Kho cov mis ntawm turbulizer thiab tswj kev nthuav dav hauv qhov kub thiab txias.
Dej Qhov Cracking thiab Infiltrating Steel
Kev tawg ntawm zirconium core nyob rau hauv cov txheej txheem pouring ua rau cov seepage ntawm hlau, uas feem ntau yuam cov nruam nruam los thaiv cov ntau lawm los yog kaw. Kev tsom xam qhia tau hais tias lub ntsiab yog vim li cas rau qhov tawg yog qhov tsis zoo thermal shock tsis kam ntawm zirconium core.
Kev daws: Volume ntom ntom ntawm zirconium core tsis tuaj yeem siab dhau, thiab qhov ntim siab dua, thermal poob siab tsis kam.
Loj Casing Repture
Loj casing yog nyob nruab nrab ntawm cov dej nkag ntawm lub ladle thiab tundish, thiab nws metallurgical muaj nuj nqi yog los tiv thaiv cov kua hlau los ntawm splashing thiab raug oxidized thaum lub sij hawm khiav ntawm cov kua hlau los ntawm lub ladle mus rau hauv lub tundish. Qhov teeb meem tshwm sim feem ntau hauv kev ua haujlwm ntawm cov pob loj loj yog qhov tawg ntawm qhov tawg.
Kev daws: Ua ntej, siv cov ntaub ntawv nrog cov thermal expansion coefficient me me thiab elastic pwm los tsim cov casing los txhim kho cov thermal poob siab. Qhov thib ob, thaum lub casing thiab lub qhov hluav taws xob dej tsis tuaj yeem sib koom, lub zog sab nraud tsis tuaj yeem siv rau hauv qhov qis ntawm lub casing.
