Muaj ntau txoj hauv kev los tso cov cib refractory hauv cov cement rotary kilns. Ua ntej, raws li cov sib txawv cib pob qij txha, cov txheej txheem ntawm refractory cib nyob rau hauv cement rotary kilns yuav muab faib ua ob hom: circumferential thiab staggered.
Nws yog qhov zoo dua los siv cov cib los tsim lub tog raj kheej hauv ib ncig. Qhov zoo ntawm lub nplhaib masonry yog tias nws yooj yim los tsim thiab rhuav tshem, tab sis nws yuav tsum xyuas kom meej tias cov cib hom thiab cib sib koom ua ke raws li qhov yuav tsum tau ua. Yog hais tias cov pob qij txha cib loj dhau lawm, nws yooj yim rau kev ua kom tsis zoo, deformation, thiab txawm tias muaj xwm txheej xws li kos duab ntau thiab ntog cib ntawm lub qhov cub hauv ob sab phlu. Yog tias cov pob qij txha me me dhau lawm, cov pob zeb hauv ob sab phlu yuav raug puas ntsoog ntxov vim muaj kev ntxhov siab ntau dhau thaum siv. Lub ntsiab tsis zoo ntawm staggered masonry txoj kev yog: ua ntej, nyuaj rau masonry thiab hauv zos kho; Thib ob, rau cov cib nrog qhov tsis sib xws thiab cov duab, qhov zoo ntawm cov masonry tsis zoo. Tam sim no, tsuas yog qee qhov me me rotary kilns nrog kev tu ncua ntev tseem siv txoj kev no.
Ntxiv nrog rau ob txoj hauv kev ntawm lub voj voog thiab staggered masonry, nws tuaj yeem muab faib ua ob txoj hauv kev: qhuav masonry thiab ntub masonry.
Qhuav masonry yog hais txog kev siv lub ntsiab ntawm cov hlau phaj thiab xauv cib los tsim cov cib rau cov teb kiln, tab sis tsuas yog siv cov av nplaum me me thaum tsim nyog. Nthuav masonry yog hais txog kev siv cov av nplaum cib, nrog cov phaj hlau tsuas yog siv thaum xauv lub cib.
Feem ntau, alkaline bricks feem ntau qhuav nteg. Tshwj xeeb tshaj yog rau dolomite bricks, qhuav masonry tsuas yog siv tau vim lawv susceptibility rau hydration. Qhov zoo ntawm cov masonry qhuav yog ceev masonry ceev, tab sis nruj yuav tsum tau rau cib puab thiab loj, tsis zoo tag nrho cov ntaub ntawv nyob rau hauv lub siab, thiab yooj yim kev nyuaj siab concentration thiab crushing ntawm cib. Yog li, thaum ntsib cov duab tsis sib xws hauv lub cev kiln lossis qhov khoob uas tshwm sim los ntawm qhov yuam kev loj hauv cov duab cib, nws yog qhov yuav tsum tau sim ua kom cov av nplaum.
Feem ntau, cov ntaub ntawv aluminium silicon feem ntau yog siv rau cov pob zeb ntub dej. Vim nws tsis tshua muaj coefficient ntawm thermal expansion, nws yooj yim rau kos ntau ntau thiab ntog bricks. Yog li, nws yog ib qho tsim nyog yuav tsum siv cov av nplaum los khi cov cib thiab txhim kho tag nrho kev ncaj ncees ntawm cov khoom hauv ob sab phlu. Kev siv siab -lub zog phosphate hluav taws av nplaum rau masonry yog ib qho kev ntsuas zoo los txhim kho tag nrho cov kev ncaj ncees ntawm txhuas silicon refractory cov ntaub ntawv thiab tiv thaiv kev kos duab ntau thiab cov cib poob.
