Thaum tsim lub qhov cub, qhov cub, lossis qhov cub, cov lus nug tseem ceeb tshaj plaws yog: "Qhov kub ntawm qhov cub cib yog dab tsi?" Kev xaiv lub cib tsis ncaj ncees tuaj yeem ua rau cov txheej txheem tsis ua haujlwm, melting, lossis raug nqi qis. Hluav taws cib, tseem hu uarefractory bricks, yog engineered los tiv thaiv huab cua kub, tab sis lawv cov kev txwv txawv heev raws li lawv cov tshuaj muaj pes tsawg leeg thiab kev tsim khoom.
Hauv phau ntawv qhia no, peb yuav rhuav tshem qhov ntsuas kub rau ntau hom hluav taws kub, piav qhia txog kev lag luam "lub luag haujlwm", thiab pab koj xaiv cov khoom tsim nyog rau koj daim ntawv thov kub siab -.
Nkag siab txog Kev Ntsuas Hluav Taws Kub Kub thiab Kev Ntsuas
Hluav taws kub cib tsis yog ib qho -size- haum- tag nrho. Kev lag luam feem ntau faib lawv raws li lawv qhov "lub luag haujlwm", uas cuam tshuam ncaj qha rau lawv qhov kev pabcuam siab tshaj plaws. Cov kev faib tawm no yog tsim los ntawm cov koom haum xws li ASTM (American Society for Testing and Materials).
1. Tsawg-Lub Luag Haujlwm Hluav Taws Xob
Qhov kub thiab txias:Mus txog 1,750℃F (954 degree)
Qhov zoo tshaj plaws rau:Cov qhov cub hauv tsev, qhov cub me me, thiab -cov qhov cub kub.
Yam ntxwv:Cov no yog cov pheej yig thiab muaj qhov zoo thermal poob siab tab sis tsis tuaj yeem ua rau cov cua sov ua kom sov.
2. Nruab nrab-Lub Luag Haujlwm Hluav Taws Xob
Qhov kub thiab txias:Txog 2,700℃F (1,482 degree)
Qhov zoo tshaj plaws rau:General furnace linings thiab Secondary kiln rwb thaiv tsev.
Yam ntxwv:Qhov kev xaiv sib npaug rau ntau qhov nruab nrab -cov txheej txheem cua sov.
3. Siab -Lub Luag Haujlwm Hluav Taws Xob
Qhov kub thiab txias:Mus txog 2,850℃F (1,565 degree)
Qhov zoo tshaj plaws rau:Ceramic kilns, iav furnaces, thiab hlau smelting.
Yam ntxwv:Cov no muaj cov ntsiab lus alumina siab dua, tso cai rau lawv nyob ruaj khov ntawm qhov kub thiab txias qhov twg qis - cov cib ua haujlwm yuav muag.
4. Super-Lub Luag Haujlwm Hluav Taws Xob
Qhov kub thiab txias:Tshaj 3,000℃F (1,650 degree)
Qhov zoo tshaj plaws rau:High -kub steel ntau lawm thiab tshwj xeeb kuaj kilns.
Yam ntxwv:Tsim los rau qhov xav tau ntau tshaj plaws, cov cib no muaj kev tiv thaiv zoo tshaj rau deformation hauv qab load.
Qhov ntsuas kub ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov cib cib
Qhov "fire bricks kub ntau" kuj nyob ntawm cov khoom siv tshwj xeeb. Nov yog cov kev sib txawv tshaj plaws pom nyob rau hauv cov chaw lag luam:
Hluav taws kub Clay Bricks (Dense Bricks)
ntomhluav taws av nplaum cibyog cov txheej txheem rau durability. Lawv qhov kub thiab txias feem ntau poob ntawm 1,250℃thiab 1,450℃(2,280℃F - 2,640℃F). Lawv muaj nuj nqis rau lawv cov neeg kho tshuab lub zog thiab tiv thaiv slag thiab tshuaj lom neeg puas.
Insulating Fire Cib (IFB)
IFBs yog lub teeb yuag thiab ntxeem tau, tsim los cuab cua sov es tsis nqus nws.
Qib 23:Rated mus txog 2,300℃F (1,260 degree).
Qib 26:Rated mus txog 2,600℃F (1,425 degree).
Qib 30:Rated mus txog 3,000℃F (1,650 degree).
Qib 32:Rated mus txog 3,200℃F (1,760 degree).
Kev siv:Feem ntau siv los ua qhov kub - lub ntsej muag hauv ob sab phlu hauv hluav taws xob kilns lossis ua cov rwb thaiv tsev thaub qab.
High Alumina Cib
Lub tshav kub tsis kam ntawm lub cib yog ncaj qha proportional rau nws alumina (Al2O3Al2O3) cov ntsiab lus. Cib nrog 50% mus rau 99% alumina tuaj yeem tiv taus kub ntawm 1,500℃txog 1,800℃(2,730℃F - 3,270℃F). Cov no yog qhov tseem ceeb rau kev lag luam steel thiab cement qhov chaw ua haujlwm kub tsis tu ncua.
Kev Ua Haujlwm Tsis Zoo: Yuav ua li cas thaum koj tshaj qhov ntsuas kub?
Tshaj qhov ntsuas hluav taws kub ntawm qhov kub thiab txias yog ib daim ntawv qhia rau kev puas tsuaj. Nov yog qhov feem ntau tshwm sim:
Vitrification thiab Softening:Lub cib pib tig mus rau hauv iav -zoo li lub xeev. Nws poob nws cov qauv kev ncaj ncees thiab yuav sag los yog bulge.
Thermal Spalling:Yog tias qhov kub thiab txias hloov sai heev, cov kev ntxhov siab sab hauv ua rau lub ntsej muag ntawm lub cib tawg los yog flake tawm.
Tshuaj degradation:Ntawm qhov kub siab heev, qee cov cib teb nrog cov tshuaj nyob rau hauv qhov cub cua sov lossis cov ntaub ntawv ua tiav, ua rau corrosion sai.
Tswv yim Pro:Ib txwm ua haujlwm tsawg kawg yog 100℃hauv qab qhov siab tshaj plaws ntsuas kub ntawm lub cib kom ntseeg tau tias lub neej ntev thiab kev nyab xeeb.
Kev Lag Luam trends: Vim li cas Kub Precision Matters hauv 2026
Raws li peb txav mus txog xyoo 2026, kev lag luam thoob ntiaj teb refractories hloov mus rau "Green Steel" thiab hydrogen- lub tshuab hluav taws xob. Cov thev naus laus zis tshiab no feem ntau xav tau ntau dua thiab ruaj khov hluav taws kub ntawm qhov kub thiab txias. Kev tsim kho tshiab hauv cov khoom siv hluavtaws yog tam sim no tso cai rau cov cib uas tuaj yeem tiv taus 1,850℃+ nrog tsawg kawg thermal expansion, txo kev txij nkawm rau kev lag luam loj.
Yuav Ua Li Cas Xaiv Txoj Cai Hluav Taws Xob rau Koj Qhov Haujlwm
Txhawm rau kom ntseeg tau tias koj nyob hauv qhov kev nyab xeeb ntawm kev siv hluav taws kub kub kub, ua raws li cov kauj ruam no:
Txheeb xyuas qhov Peak Temperature:Dab tsi yog qhov kub tshaj plaws lub qhov cub yuav tau txais? Ntxiv qhov kev nyab xeeb ntawm 10-15%.
Txiav txim siab qhov Atmosphere:Puas yog qhov txo qis lossis oxidizing huab cua? Qee cov cib ua tau zoo dua hauv qee qhov chaw tshuaj lom neeg.
Tshawb xyuas Alumina Cov ntsiab lus:Rau qhov kub siab tshaj 1,500 degree, ua qhov tseem ceeb ntawm cov ntsiab lus alumina siab (70% +).
Ntsuas Thermal Shock:Yog tias koj lub qhov cub yuav qhib thiab tawm ntau zaus, xaiv cov cib uas muaj cov thermal poob siab, txawm tias nws txhais tau tias qis dua sab saum toj me ntsis -kawg kub
To taub covhluav taws bricks kub ntau yamyog thawj kauj ruam mus rau qhov ua tau zoo siab -kub tsim. Txawm hais tias koj siv cov av nplaum qis qis rau lub qhov cub pizza lossis Qib 32 IFBs rau lub qhov cub, kev paub txog cov kev txwv yuav ua kom muaj txiaj ntsig thiab kev nyab xeeb.
