Rau cov chaw tsim cov hlau tsis xeb thiab cov hlau huv heev, qhov ruaj khov ntawm lub cub tawg VOD ncaj qha txiav txim siab qhov ua tau zoo ntawm kev tsim khoom, tus nqi tsis ua haujlwm, thiab qhov zoo ntawm cov hlau kawg. Kev khiav lub cub tawg VOD txhais tau tias tawm tsam cov xwm txheej ua haujlwm hnyav: lub tshuab nqus tsev siab, kev hloov pauv kub ntau zaus, kev ntxuav cov hlau yaj ntau heev, thiab kev xeb alkaline slag hnyav. Ntau yam teeb meem luv luv ntawm lub neej tsis yog los ntawm kev ua haujlwm yuam kev, tab sis los ntawm kev xaiv cov cib refractory tsis sib xws rau cov chaw sib txawv ntawm lub cub tawg.
Ib lub tshuab ua kom sov VOD tiav yuav tsum muaj cov khoom siv refractory uas tau muab faib ua ntau txheej sib txawv. Nov yog tsib hom cib refractory tseem ceeb uas txhua pab pawg kws tshaj lij metallurgical yuav tsum paub:
Cov Cib Magnesia-Chrome(Cov ntaub ua haujlwm tseem ceeb)
Raws li cov khoom siv ua haujlwm sab hauv uas siv dav tshaj plaws, cov cib magnesia-chrome ua haujlwm rau phab ntsa lub cub tawg, pas dej ua kua thiab kab slag - qhov chaw xeb hnyav tshaj plaws. Nrog rau kev tiv thaiv slag zoo heev, kev ua haujlwm tiv thaiv kev nkag mus thiab cov qauv kub siab ruaj khov, lawv zoo tiv taus tev thiab nyias nyias nyob rau hauv lub sijhawm ntev ntawm qhov chaw nqus tsev kub siab. Nws yog qhov kev xaiv pheej yig tshaj plaws thiab txhim khu kev qha rau kev tsim cov cub tawg VOD txheem.
Cov Cib Magnesia-Calcium(Kev daws teeb meem siab heev rau kev ua hlau)
Rau cov chaw tsim khoom uas tsom mus rau cov hlau tsis xeb zoo thiab cov hlau huv heev, cov cib magnesia-calcium yog cov khoom siv zoo tshaj plaws. Muaj kev tiv thaiv alkaline slag zoo tshaj plaws thiab kev ua haujlwm tsis muaj chromium, lawv ua raws li cov qauv ib puag ncig thiab zam kev ua qias tuaj ntawm cov hlau. Lawv cov qauv ntom ntom tiv taus cov hlau yaj uas muaj zog thiab txo cov khoom sib xyaw, ua rau cov hlau tiav huv si thiab zoo dua.
Cov Cib Magnesia Muaj Zog Siab(Hauv Qab & Daim Npog Rov Qab)
Lub hauv qab ntawm lub cub tawg thiab txheej hloov pauv xav tau lub zog thauj khoom thiab lub zog tiv thaiv kev ntxhov siab. Cov cib magnesia muaj zog siab ua rau muaj kev kub hnyiab siab, tiv taus kev sib txhuam zoo heev thiab ua haujlwm kub ruaj khov. Lawv txhawb nqa cov qauv sab saud ua haujlwm, txo qhov kev ntxhov siab thermal, thiab tiv thaiv kev tawg thiab kev pheej hmoo ntawm kev tawg thaum lub sijhawm tsim khoom ntev.
Cov Cib Rwb Thaiv Kev Sib Tw(Txheej rwb thaiv tsev sab nraud)
Kev rwb thaiv cua sov yog qhov tseem ceeb rau kev txuag hluav taws xob thiab kev tiv thaiv lub cev cub. Cov cib rwb thaiv cua sov sib dua tau siv rau txheej sab nraud ntawm lub cub, uas muaj cov khoom siv hluav taws xob tsawg thiab khaws cia cua sov zoo heev. Lawv txo qhov poob kub sab hauv, tswj qhov sib npaug ntawm cua sov ntawm lub cub, txo kev siv hluav taws xob, thiab tiv thaiv lub thav duab hlau sab nraud ntawm kev hloov pauv kub siab.
Cov Cib Alumina Siab(Cov Cheeb Tsam Pabcuam & Cov Cheeb Tsam Tshwj Xeeb)
Cov cib uas muaj alumina siab yog cov khoom siv refractories tseem ceeb rau VOD systems. Haum rau cov npog qhov cub, cov kav dej nqus tsev thiab cov chaw hloov pauv uas tsis muaj corrosion, lawv muab kev tiv thaiv thermal shock zoo heev thiab kev tiv thaiv cov pa roj flue. Lawv ua tiav cov ntaub thaiv tseem ceeb uas muaj magnesia, ua rau tag nrho cov qauv cub ruaj khov thiab siv tau ntev dua.
Kev sib phim lub cib kom raug rau thaj chaw yog qhov tseem ceeb rau kev txuas lub neej ntawm lub cub tawg VOD thiab txiav cov nqi kho tsis tau npaj tseg.
Peb muab cov cib ua los ntawm VOD refractory uas ua tau raws li koj xav tau thiab cov kev daws teeb meem tsim qauv ib zaug rau cov tuam txhab ua hlau thoob ntiaj teb. Yog tias koj tab tom nrhiav cov khoom siv refractory uas ruaj khov thiab siv tau ntev los ua kom koj lub cub tawg ua haujlwm tau zoo, thov hu rau peb kom tau kev sab laj txog kev tshaj lij.
