Hauv lub iav tsim kev lag luam, cov kev xaiv ntawm refractory ua si ib tug pivotal lub luag hauj lwm hauv kev txiav txim siab ua tau zoo, ruaj khov, thiab kev tsim khoom zoo. Ntawm ntau txoj kev xaiv muaj, acid refractory bricks - feem ntau ua los ntawm high-purity silica - yog qhov tshwj xeeb uas muaj lub ntsej muag zoo ib yam li iav rauv, cov regenerators, thiab kev sib txuas lus.
Lawv cov tshuaj thiab lub cev ua rau lawv tsis zoo haum rau qhov chaw hnyav hauv cov chaw ua kom zoo nkauj. Hauv qab no yog qhov zoo tshaj plaws ntawm kev siv Acid Refractory cib hauv lub iav tsim kev lag luam.
1. Tshwj xeeb tsis kam rau Acidic Ib puag ncig
Iav Ntau Lawm yuav tuav thiab yaj ntawm cov khoom ntim raw uas tuaj yeem tsim cov tshuaj pleev ib ce thiab cov seem. Lawv tau tsim tshwj xeeb los tawm tsam cov acidic nres, ua rau lawv zoo tagnrho rau ib puag ncig ib puag ncig. Lawv tau ruaj khov thaum nthuav tawm cov roj acidic thiab slag uas ib txwm ua rau lwm hom kev refractories feem ntau.
Cov kua qaub no ua kom cov txheej txheem kev ntseeg siab ntawm cov hluav taws xob txuas ntxiv, txo qhov kev pheej hmoo ntawm cov qauv kev sib kis tau ntawm cov qauv kev ua kom zoo. Nws kuj txiav tawm kev txij nkawm kev xav tau tshwm sim los ntawm acid corrosion, ua rau kev pab ntau dua thiab kev ua haujlwm zoo dua.
2. Kev kub siab muaj peev xwm
Ib qho ntawm qhov tseem ceeb tshaj plaws rau cov ntaub ntawv siv hauv cov iav cub yog qhov muaj peev xwm tiv nrog kev tiv thaiv tsis tshua muaj kev ntxhov siab. Acid refractory bricks, especially those made from silica, offer outstanding high-temperature stability, with a softening temperature well above 1600 degree (2912 degree F).
Hauv iav tsim tawm, qhov twg cua sov ntau tshaj li 1500 acid refractory cib tswj tau lawv cov qauv teeb tsa thiab daim ntawv, txawm tias tom qab lub sijhawm ntev. Lawv cov kev nthuav dav tsawg ntawm cov kev nthuav dav kub tiv thaiv kev ua rog thiab tawg, kom muaj cov cua sov ua kom lawv cov qauv zoo thiab ua haujlwm thoob plaws lawv lifespan.
3. Tsawg Thermal Conductivity thiab Zog Kev Ua Haujlwm
Lwm qhov tseem ceeb ntawm cov kua qaub refractory yog lawv cov thermal basings lossis cov kev refactories theem pib. Qis dua thermal conductivity yuav tsum khaws kom sov sab hauv lub cub tawg hauv lub cub tawg thiab kev txhim kho hluav taws xob thiab txo cov roj noj.
Los ntawm kev txo cov cua sov ua kom dhau los ntawm cov tshuab cua sov thiab lub ru tsev, acid Refractory cib pab txhawb kom muaj cov khoom siv kub zoo ib yam hauv qhov cub. Qhov kev ruaj khov no zoo dua melting zoo, txo cov khoom tsis xws luag, thiab thaum kawg ua rau cov nqi qis rau cov khoom lag luam qis rau cov iav tuam tsev.
4. Zoo heev mechanical zog thiab kav ntev
Cov chaw ua kom sov hauv cov iav nroj tsuag tau tsis yog rau cov kev ntxhov siab ntau dua tab sis kuj rau cov kev ntxhov siab, thiab qee zaus kev cuam tshuam thaum lub sijhawm txij nkawm. Lawv paub txog lawv lub siab compressive thiab cov khoom muaj peev xwm zoo heev ntawm cov kub.
Lawv lub peev xwm tiv thaiv spalling (tawg lossis ya los ntawm kev hloov pauv kub sai) thiab hnav tshuab ua haujlwm rau lub neej ntev ua haujlwm. Qhov no robustness ncaj qha txhais mus ua kev kho kom rov kho dua, cov nqi kho tus nqi qis dua ntawm cov cua sov rauv - txhua qhov tseem ceeb rau kev tswj kev tswj kev sib txuas lus txuas ntxiv.
5. Qhov seem ruaj khov thiab kev coj tus cwj pwm
Thaum lub khob lub iav melting, qhov seem ruaj khov ntawm cov cub hluav taws xob ntawm cov kab ntawv cub yog qhov tseem ceeb rau cov khoom lag luam zoo ib yam.Acid Refractory cib, tshwj xeeb cov pob zeb Silica tshwj xeeb, ua rau pom cov cwj pwm uas pom tau tias nyob rau hauv kev ua haujlwm, nrog qhov tsawg kawg nkaus lossis nthuav dav.
Qhov seem ruaj khov no pab tiv thaiv kev ua kom tsis zoo ntawm cov cua sov, thiab ua kom muaj kev pheej hmoo ntawm cov kev pheej hmoo ntawm kev sib tsoo ntawm cov pob qij txha. Qhov kev ua tau zoo ntawm cov kua qaub refraction Cib kuj tseem yuav npaj cov khoom sib luag, raws li engineers muaj peev xwm xav tau cov ntaub ntawv yuav coj li cas lub sijhawm.
