Silica Mullite Cib: Qhov Kev daws teeb meem zoo tshaj plaws rau kev siv hauv kev lag luam kub siab

Hauv ntiaj teb ntawm kev lag luam kub siab, kev xaiv cov ntaub ntawv refractory ncaj qha txiav txim siab qhov ua tau zoo ntawm kev tsim khoom, kev nyab xeeb, thiab kev tswj tus nqi.Silica Mullite Cib(tseem hu ua Silica-Mullite Refractory Bricks) tau tshwm sim los ua qhov kev hloov pauv loj, ua tsaug rau lawv qhov kev ruaj khov thermal zoo heev, lub zog siab, thiab kev tiv taus corrosion zoo heev. Txawm hais tias koj tab tom khiav lub qhov cub cement, lub qhov cub iav, lossis lub boiler kev lag luam, cov cib no muab kev ua tau zoo tsis muaj qhov sib piv kom koj cov haujlwm khiav tau zoo.

1. Vim li cas Silica Mullite Cib thiaj li sawv tawm: Cov txiaj ntsig tseem ceeb

Ua ntej peb yuav tham txog lawv daim ntawv thov, cia peb hais txog cov yam ntxwv tseem ceeb uas ua rau Silica Mullite Bricks tsis tseem ceeb rau cov chaw kub siab:
Kev Tiv Thaiv Kev Poob Siab Zoo Tshaj Plaws:Nrog rau qhov coefficient ntawm kev nthuav dav thermal qis, lawv tuaj yeem tiv taus qhov kub hloov pauv sai (los ntawm qhov kub heev mus rau qhov txias) yam tsis muaj kev tawg - qhov tseem ceeb rau cov txheej txheem uas muaj cov voj voog thermal ntau zaus.

Kev kub hnyiab siab:Lawv tswj tau qhov ruaj khov ntawm qhov kub txog li 1750 ° C (3182 ° F), ua rau lawv zoo tagnrho rau cov lag luam uas kub heev tas li.

Lub Zog Kho Kom Zoo Kawg Nkaus:Txawm tias nyob rau hauv cov khoom hnyav thiab kev ntxhov siab thermal, lawv tiv taus kev hloov pauv, txo qhov xav tau hloov pauv ntau zaus thiab lub sijhawm tsis ua haujlwm.

Kev Tiv Thaiv Kev Xeb thiab Kev Yaig:Lawv tiv taus cov tshuaj lom neeg xws li cov slag uas yaj, alkalis, thiab cov pa roj acidic—uas muaj ntau hauv kev tsim cov cement, hlau, thiab iav.​

Kev Ua Haujlwm Thermal Tsawg:Pab khaws cua sov hauv cov cub tawg lossis cov qhov cub, txhim kho kev siv hluav taws xob thiab txo cov nqi roj.

2. Cov Ntawv Thov Tseem Ceeb: Qhov twg Silica Mullite Bricks Zoo Tshaj Plaws

Cov cib Silica Mullite muaj ntau yam thiab tsim los ua kom tau raws li qhov xav tau tshwj xeeb ntawm ntau yam kev lag luam kub siab. Hauv qab no yog lawv cov kev siv tseem ceeb tshaj plaws:

2.1 Kev Lag Luam Cement: Muab Fais Fab Rau Lub Qhov Cub Thiab Thaj Chaw Ua Kom Kub

Cov txheej txheem tsim cov cement vam khom rau qhov kub siab tas mus li - tshwj xeeb tshaj yog nyob rau hauv lub qhov cub rotary thiab thaj chaw calcination. Silica Mullite Bricks yog qhov kev xaiv zoo tshaj plaws ntawm no vim tias:

Lawv tiv taus qhov kub heev (1400–1600°C) thiab kev ntxhov siab ntawm lub qhov cub uas tig, qhov twg lwm cov cib feem ntau tawg lossis hnav sai sai.

Lawv txoj kev tiv thaiv rau alkali tawm tsam (los ntawm cement clinker) tiv thaiv kev puas tsuaj ntawm cib, ua rau lub cub tawg ntev dua thiab txo cov nqi kho.

Siv Cov Ntaub Ntawv:Cov chaw tsim cement loj thoob ntiaj teb siv Silica Mullite Bricks hauv thaj chaw kub hnyiab thiab thaj chaw hloov pauv ntawm lub qhov cub rotary, txo lub sijhawm tsis ua haujlwm los ntawm 30%.

2.2 Kev Lag Luam Iav: Kev Ua Kom Pom Tseeb thiab Sib Xws

Cov cub tawg iav ua haujlwm ntawm qhov kub tshaj 1600 ° C, nrog rau cov iav yaj thiab cov pa roj volatile ua rau muaj kev hem thawj tas li rau cov ntaub ntawv refractory. Silica Mullite Bricks daws cov teeb meem no:

Lawv tiv taus xeb los ntawm cov iav yaj thiab cov boron oxides (uas feem ntau pom muaj nyob rau hauv kev tsim iav), zam kev ua qias tuaj uas cuam tshuam rau qhov zoo ntawm iav.​

Lawv qhov kev ruaj khov thermal ua kom muaj kev faib cua sov sib npaug, tiv thaiv cov chaw kub uas ua rau cov iav puas (piv txwv li, npuas, tsis sib npaug).

Zoo Tshaj Plaws Rau: Cov khoom siv rov ua dua tshiab, cov chav kuaj xyuas, thiab cov cheeb tsam yaj ntawm cov iav ntab, iav thawv, thiab cov cub tawg iav tshwj xeeb.

2.3 Hlau & Metallurgy: Tiv taus cov hlau yaj & slag

Hauv kev ua hlau, tshwj xeeb tshaj yog nyob rau hauv cov cub hluav taws xob arc (EAFs) thiab cov cub ladle, Silica Mullite Bricks tiv thaiv cov khoom siv los ntawm cov hlau molten, slag, thiab cov pa kub siab:

Lawv ua tau siab dua qhov kev sib txhuam thiab kev cuam tshuam ntawm cov hlau uas yaj, txo qhov kev puas tsuaj ntawm cov cib thiab ua kom lub qhov cub hluav taws xob siv tau ntev dua.

Lawv txoj kev tiv thaiv rau cov hlau oxide thiab slag corrosion tiv thaiv cov linings tsis ua haujlwm uas ua rau kev tsim khoom kim heev nres.

Qhov Chaw Siv: Sab hauv ntawm EAF sidewalls, hauv qab ladle, thiab cov thawv refining thib ob.

2.4 Cov Boilers thiab Incinerators rau Kev Lag Luam: Kev Khaws Cia Kub Txhim Khu Kev

Cov chaw hlawv khib nyiab thiab cov boilers lag luam (piv txwv li, rau kev tsim hluav taws xob) ntsib qhov kub thiab txias siab thiab cov pa roj tawm corrosive. Silica Mullite Bricks muab:​

Kev khaws cia cua sov kom ua rau lub boiler ua haujlwm tau zoo dua, txo kev siv roj thiab cov pa roj carbon dioxide.

Tiv taus cov pa roj acidic (piv txwv li, SO₂, HCl) los ntawm kev hlawv pov tseg, tiv thaiv kev puas tsuaj ntawm cib thiab ua kom lub cib ua haujlwm tau ntev.

Siv Qhov Xwm Txheej: Kev siv cov ntaub thaiv ntawm cov cub tawg boiler, cov chav hlawv pov tseg kom muaj zog, thiab cov tshuaj oxidizing thermal.​

2.5 Lwm Cov Chaw Kub Siab

Silica Mullite Bricks kuj pom siv rau hauv:

Cov Qhov Cub Uas Ua Los Ntawm Cov Khoom Siv Ua Los Ntawm Cov Khoom Siv Uas Muaj ...Rau kev hlawv cov vuas ceramic, cov khoom siv hauv chav dej, thiab cov khoom siv ceramic siab heev, qhov twg kev tswj qhov kub kom raug yog qhov tseem ceeb.

Cov chaw tsim khoom siv roj av:Hauv cov catalytic crackers thiab reformers, tiv taus kub siab thiab hydrocarbon corrosion.

Cov Cub Kuaj thiab Kev Tshawb Fawb:Rau kev kawm thiab kev tshawb fawb txog kev lag luam, qhov twg kev ruaj khov ntawm qhov kub thiab txias heev tsis tuaj yeem sib tham tau.
