Dhau li ntawm cov kub kub, lub Kilneye Refractory yuav tsum tau ua kom muaj kev puas tsuaj los ntawm kev ntxhov siab, kev ntxhov siab thiab tshuaj lom neeg thaum siv. Raws li nws qhov kev ua haujlwm tiag tiag, peb lub tuam txhab tau tsim tshwj xeeb Kilneye Refractory Casable. Nws yog kev coj tus cwj pwm ntawm kev ua kom muaj zog, siab dua ua haujlwm, zoo thermal poob siab, thiab ntawm 10 txog caug lub neej, nce siab ntawm cov neeg siv.
Cov refractory ob sab ntawm lub qhov ncauj qeeb ntawm lub qhov ncauj uas tsis muaj zog, yog qhov muaj kev kub ntxhov ntawm kev ua kom sov thiab kub thiab txias The damage of the lining is mainly: cracking, spalling and abrasion, so the refractory material must have good thermal shock resistance, wear resistance and alkali resistance.
Thaum lub qhov ncauj lub qhov ncauj lub tog raj kheej ntawm lub teb chaws lub teb chaws tsis yog deformed, nws feem ntau yuav tau tsim cov khoom siv cov pob zeb loj, thiab ua kom cov cib ncaj qha, thiab ua kom cov cib ncaj qha, ua kom cov tub rog sib koom tes ua ke Txawm li cas los xij, lub tog raj kheej deformation muaj ntau, yog li Refractory castables tau muab tso tawm raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov khoom siv hluav taws xob kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov kev cai ua kom tau raws li cov khoom siv hluav taws xob ntau ntau yam.
Cov khoom lag luam
Nyob rau txawv teb chaws teb chaws, corundum thiab high-aluminium hlau fiber ntau txhawb cov refractory castables tau mus txog 2 txog 8. Lub Castable muaj lub siab Aluminium cov ntsiab lus thiab lub zog muaj zog. Yog li ntawd, cov thermal poob siab tsis zoo yog tsis zoo, nws yog ib qho yooj yim mus tawg thiab tev tawm, thiab kev pabcuam lub neej yog txo. Kev xyaum ntau lawm tau muaj pov thawj tias kev siv cov ntaub ntawv ntawm cov hlau fiber ntau ntxiv los txhawb cov high-aluminium Refractory castables yog qhov zoo dua li ntawm Corundum castables.
Cov hlau fiber cuam tshuam kev txhawb nqa corundum thiab high-aluminium Refractory Castables siv nyob rau hauv lub qhov ncauj Refractory Castables siv nyob rau hauv lub qhov ncauj me me, yog, lub thermal poob siab tsis zoo thiab lub neej pabcuam yog tsawg. Peb lub tuam txhab tau tsim cov high-aluminium refractory castables, High Aluminium Mullite Refractory Casab, thiab lwm yam, nrog kev pabcuam lub neej ntawm ntau tshaj ib xyoos, thiab tau ua tiav cov txiaj ntsig zoo.
Nws yog qhov paub zoo uas clay cib zoo dua li high-aluminium cibs hauv thermal poob siab thiab alkali tsis kam vim tias cov ntsiab lus tsawg; Lub zog siab, hnav tsis zoo thiab tsis zoo seismic tiv thaiv. Nyob rau hauv lub qhov ncauj me me, lub ntsiab lus Al2o3 yog 50% rau 70%, kev ua kom haum rau lub zog (1100 degrational Nws yuav tsum tau taw qhia tias kev refactory casable yog tsim los ntawm kev sib sau ua ke, hmoov, binder thiab admixature (cov khoom siv). Theem kev sib xyaw ua ke hauv kev sib xyaw ua ke nyob rau hauv lub xeev tsis-sib npaug ua ntej siv. Thaum siv nyob rau hauv cov kub siab, cov khoom siv hauv kev sib raug zoo ntawm theem kev sib raug zoo ntawm theem tshiab sib luag (uas yog, tau txais kev ua haujlwm zoo thiab hauv-situ cov tshuaj tiv thaiv). Yog li, cov ntaub ntawv tivthaiv haum yuav tsum tau xaiv thiab lub batch tsim yuav tsum tau ua kom tiav zoo kom ua tiav zoo kom ua tiav, corrosion tsis kam thiab kub kub cov khoom siv.
Cov dej xav tau ntawm Kiln Castable feem ntau kuj kuj feem ntau me, thiab nws yuav tsum tau nruj me ntsis tswj hwm raws li cov lus qhia kom tiv thaiv kom tsis txhob raug cuam tshuam. Cov pob qij txha nthuav dav tau teeb tsa thaum lub sijhawm pouring. Nco ntsoov tsis txhob nco lawv. Ib qho yog teeb tsa txhua txhua 800 hli nyob rau hauv lub limhiam kev taw qhia thiab ib qho yog teeb tsa hauv nruab nrab thaum ntev ntev tshaj 1m (qhov loj me: L × 120mm). Kev ntsuas dej tsis yuav tsum tau ua ntawm kev sib txuas ntawm cov Castable thiab cov ntawv sib cais los ntawm cov kab mob yas los ntawm cov dej ntws rov qab los ntawm kev poob dej. Lub kiln yuav tsum tsis txhob tig mus nyob rau hauv 12 teev tom qab pouring ua tiav.
