Qhov kev ua haujlwm kom yog ntawm lub ladle swb muaj qhov cuam tshuam ncaj qha rauKev Nyab Xeeb Ntau Lawm, Hlau Zoo thiab Khoom Siv Lub NeejCov. Cov txheej txheem kev ua haujlwm hauv qab no thiab cov kev ceev faj siv tau txuas ntxiv mus txuas ntxiv ua pov thawj, tuag casting thiab lwm yam xwm txheej.
1. Kev ua haujlwm ua ntej
(1) Kev lees paub ntawm Skubding Txheej Txheem
Refractory Parts:
Sab sauv thiab qis dua swb daim hlau yog dawb ntawm cov kab nrib pleb, spalling lossis loj hlob lossis hnyav ntawm lub qhov loj dua lossis sib npaug rau 60% ntawm thawj loj).
Lub rooj cib siab, tsis muaj kab ntawm cov hlau nkag.
Neeg Kho Tshuab Kuaj:
Tsis muaj xau ntawm hydraulic / hluav taws xob ntaus ntawv, lub ntsej muag zoo siab siab siv cov zaub (feem ntau10-15 mpa ).
Swb cov ntsia hlau dawb ntawm cov nplais thiab cov dej zoo (nrogGraphite raws li kub kub ).
Sealing xeem:
Los ntawm txhais tes xeem swb 3 zaug kom paub meej tias tsis muaj jamming thiab tsis muaj qhov khoob khoob thaum kaw.
(2) Kev Npaj Ladle
Ci lub ladle rauNtau dua los yog sib npaug rau 800 degree(Zam kev ua kom thermal poob siab puas rau daim ntaub qhwv).
Paub meej tias cov muaj pes tsawg leeg ntawm cov hlau thiab xaub phaj phim (xws li stainless hlau nrogZro₂-c swb phaj ). 2.
2. Slide qhib cov txheej txheem ua haujlwm
(1) Qhov kev qhia thawj zaug
Nco ntsoov tias daim ntaub qhwv yogtag muab kaw(qhov yog misaligned thiab tsis muaj molten steel ntws tawm).
Nyob rau hauv rooj plaub ntawm nruam casting, nruabib qho ntev ntev (shroud)thiab energize nrog cov roj inert (xws li ar).
(2) maj mam qhib
Sim qhib nrog cov ntws tsawg (10% {1}}}% qhib):
Hydraulically thawb lub qis dua swb maj mam thiab saib Molten Steel ntws.
Kos rauMolten Hlau Txhaumlossisswb toastage.
Kho rau cov txheej txheem qhib:
Kho qhov qhib (piv txwv30%-70%Rau kev nruam casting) Raws li kev nruam casting rub nrawm los yog puab Casting xav tau.
Ua kom tus nqi ntws ruaj khov thiab zam kev hloov pauv hloov.
(3) Kev Saib Xyuas Kev Ua Haujlwm
Real-Lub Sij Hawm Tswj Xyuas:
Swb qhib (sib txawv ntawm cov nqi uas muaj nqi tsawg dua lossis sib npaug ntawm {0. 5 hli).
Steel ntws (txuas nrog lub Intermediate ladle kua qib tswj).
Zawv zawg phaj (Lub Cua Sov Hluav Taws Xob Hluav Taws Xob Hluav Taws XobTsawg dua los yog sib npaug rau 300 degree ).
Kev kho mob txawv txav:
Yog tias pom cov tocolate pom, tam sim ntawd txo qhov qhib thiab tshawb xyuas lub zog compression.
Yog tias tsav tsis ua tiav, hloov mus rau cov thaub qab system lossis phau ntawv hom.
3. Cov txheej txheem ua haujlwm ntawm khau cab kaw
(1) Kaw ib txwm (xaus ntawm pouring)
Maj mam txo tau qhov qhib:
Ua kom me duaQhov qhibrau10%Ua ntej los txo qhov cuam tshuam ntawm cov hlau ntws.
Ceev ceev thiab ua tiav kaw:
Lub system hydraulic rub tawm rov qab ntawm tag nrho cov ceev kom ntseeg tau lub qhov yog kiag li tsis muaj tseeb (lub sijhawm txiav txim<1 second ).
Foob Kev Pom Zoo:
Saib hauv qab ntawm lub tsevTsis muaj steel dripping, tsis muaj seem steel ntws hauv qhov hluav taws xob ntev.
(2) kev kaw thaum muaj xwm ceev (so tsis tau)
Ua rau lub pob muag ceev: ncaj qha txiav tawm lub zog hydraulic, lub caij nplooj ntoo hlav hluav taws xob cia li kaw tus swb phaj.
Los Ntawm Txhais Tes Los Ntawm Kev Ua Haujlwm: Siv tus nqi ceev los yuam kom kaw (yuav tsum muaj kev niaj zaus).
4. Kev Ua Liaj Ua Haujlwm Hloov Kho Cov Haujlwm Tshwj Xeeb
(1) Hloov cov xwm txheej
Xaub phaj lub qhov yaigNtau dua los yog sib npaug rau 40% ntawm cov tuab tuab.
Nkag mus rau cov kab nrib pleb lossis kev xau loj.
(2) Cov txheej txheem hloov
Txias: Lub tsev pw tau tso cai rau sawv ntawmTsawg dua los yog sib npaug rau 100 degree.
Disassemble lub ntsej muag sab qub:
Tso tawm cov khoom siv compression thiab tshem tawm cov kev txhim kho bolts.
Ntxuav lub refractory sludge sab laug ntawm kev tiv tauj saum npoo ntawm lub rooj zaum.
Nruab daim phaj tshiab:
Ua ntaub ntawvAluminium-Carbon Refractory Maas, ua kom paub tseeb tias nws yog tiaj tus thiab dawb ntawm huab cua npuas.
Zawm lub bolts hauv kab pheeb ces kaum (torque50-70 N-m ).
Kev Ntsuas:
Swb 5 zaug uas tsis muaj thauj mus kom paub tseeb tias tsis muaj kev kub ntxhov.
Kev Nyuaj Siab Tso Tawm Khiav(Qhib tsawg dua lossis sib npaug rau 20%) rau thawj pouring.
5. Kev ceev faj kev nyab xeeb
(1) tus neeg teb xov tooj tiv thaiv
HnavKub-Kub Resistant Tiv Thaiv Khaub Ncaws, npog ntsej muag thiab hnab looj tes.
Tsis txhob sawv hauv qab lub ladle lossis hauv kev txav ntawm cov xaub tsav tsheb.
(2) kev nyab xeeb khoom siv
Thaum swb yog qhib, nws yog nruj me ntsis txwv rauntaus lub ladlelossisKho cov lus qhib sai sai(anti-txaws).
Thaum cov kab ke hydraulic tawm ntawm kev pabcuam, tua lub zog thiab daws lub siab.
(3) Kev Tswj Xyuas Ib puag ncig
Khaws qhov chaw nchuav kom qhuav kom tiv thaiv cov pa dej los ntawm kev tiv tauj cov hlau kub thiab ua rau tawg.
Npog spilled molten hlau nrogQhuav magnesium xuab zebThiab tsis txhob yaug nrog dej.
