Nyob rau hauv kev lag luam steelmaking, cov chav sov pib ua kom ruaj khov (bof) cia siab rau cov khoom siv refractory tshwj xeeb ntawm cov kev mob siab ntawm cov dej yaig siab thiab tshuaj yaig. Cov ntaub ntawv no tseem ceeb heev rau kev tswj cov efficiency thiab ntev ntawm lub cub tawg. Ntawm no yog cov khoom siv refactory thawj siv hauv bof:
1. Magnesia -} carbon cib
Magnesia Carbon CibYog siv dav hauv cov hnab looj tes rau hauv cov ntaub qhwv tau vim lawv tau txais txiaj ntsig zoo tshaj plaws thiab muaj peev xwm tiv thaiv kom kub siab. Cov cib no yog tsim cov magnesia (MgG) thiab carbon, uas muab siab tiv taus rau slag yaig thiab spalling. Cov pa roj carbon cov ntsiab lus pab rau kev txo cov oxidation, thaum cov magnesia ua kom muaj zog ua kom muaj zog ua kom muaj kev ruaj khov.
2. High Alumina Refractory Cib
High Alumina Cibyog lwm cov khoom siv tseem ceeb siv hauv bof. Cov pob zeb no tau paub rau lawv lub zog zoo dua thiab hnav tsis kam, ua rau lawv haum rau thaj tsam ntawm cov cua sov uas muaj kev ntxhov siab. Siab {- Alumina Cib tuaj yeem tiv taus kub txog 1800℃thiab tiv taus tshuaj lom neeg.
3. Magnesia -} chrome cib
Magnesia - chrome tua hluav taws muaj kev tiv thaiv zoo heev rau tshuaj tua thiab cua sov. Lawv yog cov muaj txiaj ntsig tshwj xeeb hauv thaj chaw ntawm lub pob tw uas slag thiab tshuaj yaig uas hnyav heev. Cov cib no muaj ob qho tib si magnesia thiab chromia, uas txhim kho lawv cov kev ua haujlwm ruaj khov thiab ua tau zoo.
4. Alumina - Magnesia Cib
Alumina - Magnesia cib ua ke cov txiaj ntsig ntawm ob lub alumina thiab magnesia, muab kev sib npaug ntawm lub zog siab thiab lub zog cua sov. Cov pob zeb no tau siv ntau yam ntawm cov bof, suav nrog cov haujlwm ua haujlwm thiab thaj chaw taphole.
5. Silicon Carbide Castables
Silicon carmide refractory castables yog siv rau lawv lub siab thermal conductivity thiab hnav tsis kam. Cov zaub mov ua no tau tshwj xeeb hauv cov cheeb tsam uas tau txias sai thiab cua sov ua voj voog yog ib qho muaj, xws li lub qhov tapole thiab laser tshuab.
6. Phosphating Bonded Refractics
Phosphate - bewed refractory refractics yog siv rau kev kho thiab kho cov ntawv thov hauv bof. Cov ntaub ntawv no muab cov teeb tsa sai thiab muaj lub zog siab, ua rau lawv zoo tagnrho rau kev ua kom pom thiab kho cov ntawv puas tsuaj.
7. Insulating Cib Hluav Taws Xob
Insulating Cov Hluav Taws Xob Hluav Tawssiv nyob rau hauv bof los txo cov cua sov poob thiab txhim kho kev txuag hluav taws xob. Cov cib no muaj tsawg thermal conductivity, uas pab ua kom muaj kev tswj hwm qhov kub thiab txias ntawm lub cub tawg thiab txo kev siv hluav taws xob.
Cov ntaub ntawv sau ua refractory rau cov khoom siv roj oxygen yooj yim yog qhov tseem ceeb rau kev ua tau zoo thiab ntev ntawm cov txheej txheem steelmakakaking. Txhua cov ntaub ntawv muaj cov khoom tshwj xeeb uas ua rau muaj kev ua tau zoo tag nrho thiab ruaj khov ntawm lub cub tawg. Los ntawm kev nkag siab txog cov cai tshwj xeeb ntawm cov sib txawv ntawm cov khoom lag luam hauv bof, cov khoom lag luam tuaj yeem xaiv cov khoom lag luam uas tsim nyog tshaj plaws los txhim kho kev ua haujlwm.
