Cov teeb meem feem ntau ntawm kev siv cov khoom siv tundish refractory, qee qhov yog cov teeb meem zoo ntawm cov khoom siv lawv tus kheej, thiab qee qhov yog cuam tshuam nrog kev tsim kho qhov chaw, yuav tsum tau soj ntsuam thiab tshuaj xyuas zoo. Yog li ua raws li kuv thiab nrhiav cov teeb meem thiab kev daws teeb meem ntawm kev teeb tsa tundish refractory.
Cov khoom qhuav / Cov khoom qhuav tsis muaj zog
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 tawg thiab cuam tshuam rau kev tsim cov khoom siv tas mus li. Tom qab kev soj ntsuam thiab kev tshuaj xyuas ntev, nws tau xaus lus tias cov laj thawj tseem ceeb rau cov khoom tsis muaj zog lossis cov khoom qhuav yog raws li nram no:
(1) teeb meem ci: lub cuab yeej ci tundish siv hauv cov hlau cog yog lub tshuab ci roj, uas yuav ua rau muaj ntau cov tar hauv cov kav dej lossis ua rau lub hlawv puas tsuaj tom qab siv ntev, ua rau muaj kev ci tsis zoo hauv zos thiab tsis muaj lossis tsis muaj zog.
(2) cov khoom qhuav uas ntub dej nkag mus: cov khoom qhuav muaj 70% ntawm cov khoom me me thiab 30% hmoov zoo. Cov hmoov zoo muaj cov xuab zeb magnesia thiab cov neeg sawv cev khi. Vim tias nws muaj qhov chaw tshwj xeeb siab, cov hmoov zoo yooj yim nqus dej thiab ntub.
Kev daws teeb meem: Ua ntej tshaj plaws, nws yog qhov tsim nyog los xyuas kom meej tias lub roaster ci zoo, ntxuav cov kav dej roj tas li, tshem tawm cov tar thiab hmoov av, thiab hloov cov hlawv puas raws sijhawm; qhov thib ob, nws yog qhov tsim nyog los xyuas kom meej tias cov ntaub ntawv qhuav qhuav thiab sib tov sib npaug.
Cov Nkoj Uas Muaj Cua Ntxuam
Qee zaum, lub turbulizer yuav mus dhau ntuj txiag teb tsaus ntawm qhov chaw ntawm cov hlau ua kua hauv cov txheej txheem ntawm ntau lub cub tawg tas mus li casting, uas tsis tuaj yeem tswj cov hlau ntws thiab tiv thaiv thaj chaw cuam tshuam, uas yog qhov tsis zoo rau qhov zoo thiab kev nyab xeeb ntawm cov hlau ua kua.
Kev daws teeb meem: Kho cov mis ntawm turbulizer thiab tswj qhov kev nthuav dav hauv qhov kub siab.
Kev Tawg Qhov Dej thiab Hlau Nkag Mus Rau Hauv
Qhov tawg ntawm zirconium core thaum lub sijhawm nchuav ua rau cov hlau ntws, uas feem ntau yuam kom qhov kev casting tas mus li thaiv kev tsim khoom lossis kaw. Kev tshuaj xyuas qhia tau hais tias qhov laj thawj tseem ceeb rau qhov tawg yog qhov tsis zoo thermal shock tiv taus ntawm zirconium core.
Kev daws teeb meem: Qhov ntim ntawm zirconium core tsis tuaj yeem siab dhau, thiab qhov ntim ntau dua, qhov tsis kam ntawm thermal shock zuj zus.
Kev tawg loj ntawm lub plhaub
Lub plhaub loj nyob nruab nrab ntawm qhov nkag dej ntawm lub ladle thiab lub tundish, thiab nws lub luag haujlwm metallurgical yog los tiv thaiv cov hlau kua los ntawm kev txaws thiab raug oxidized thaum lub sijhawm ntws ntawm cov hlau kua los ntawm lub ladle mus rau hauv lub tundish. Qhov teeb meem feem ntau hauv kev ua haujlwm ntawm lub plhaub pob loj yog tawg hla tawg.
Kev daws teeb meem: Ua ntej, siv cov ntaub ntawv uas muaj cov coefficient me me ntawm kev nthuav dav thermal thiab cov pwm elastic los tsim lub casing kom txhim kho qhov kev tiv thaiv thermal shock. Qhov thib ob, thaum lub casing thiab qhov dej tawm tsis tuaj yeem sib koom, lub zog sab nraud tsis tuaj yeem siv rau sab qis ntawm lub casing.
