Txhawm rau txuas ntxiv cov kev pabcuam lub neej ntawm lubRefractor CibNtawm Cement Quary Quary Quary Redary Litary CLinker yog txuas rau nws sab ua ib txheej tiv thaiv, uas yog cov tawv nqaij ntawm cov tawv nqaij. Nyob rau hauv cov kev mob siab, kev sib cuam tshuam ntawm Mement clinker thiab refractory cov ntaub ntawv los ua cov tawv nqaij me me yog qhov tshwm sim nyuaj. Los ntawm cov kev xav ntawm cov ntaub ntawv refractory, cov teeb meem no cuam tshuam ntau cov teeb meem thaum ua kev tawm tsam thaum muaj kuab lom thiab tshuaj lom neeg ntawm cov khoom siv hluav taws xob. Lub Qhab feem ntau tswj qhov kub ntau tshaj li 1450 degree, thiab cov hlau phaj ntawm lub tog raj kheej tsis tuaj yeem tiv taus ntau dua. Txhawm rau tiv thaiv lub tog raj kheej mais, ib txheej ntawm refractory rab phom yog txwv, tab sis lawv tsis tuaj yeem tiv thaiv cov hluav taws xob hauv qab ntev thiab corrosion ntawm cov khoom siv tshuaj. Cov nqaij daim tawv thiab tsis yog tsuas yog ua rau txuas ntxiv rau lub neej ntawm refractory bricks, tab sis kuj txo cov cua sov dissipation ntawm kiln lub tog raj kheej thiab txhim kho kev ua haujlwm ua haujlwm.
Kiln daim tawv nqaij yuav ua rau cov phuam refractory li cas?
Cov khoom txav ntawm qhov txias txias mus rau qhov kawg kub kawg hauv lub cub cub. Thaum nws nkag mus rau thaj chaw tua hluav taws, thiab cov kua dej tshwm sim, thiab cov nyiaj ntau theem nce nrog qhov ntsuas kub. Cov theem ua kua ntawm cov khoom muaj cov nplaum muaj cov nplaum yuav txo qis nrog qhov nce ntxiv ntawm qhov kub thiab txias, yog li cov tawv nqaij kom dai thaum hlawv lub luj. Thaum lub qhov cub hluav taws kub tsis ua cov theem ua kom tsis txhob ua rau lub xeev overheated, cov khoom muaj qhov loj tshaj viscosity. Thaum refractory cib yog nias nyob rau hauv cov khoom, ob lo ua ke thiab yidgo tshuaj hloov. Tom qab ntawd, raws li qhov kub nce, lawv solorify los ua thawj txheej txheej ntawm cov tawv nqaij kiln. Tib lub ntsiab cai yog siv los ua qhov thib ob, thib peb, thiab ... txheej ntawm cov tawv nqaij xwb. Raws li cov tawv nqaij Kiln yog dai rau lub sijhawm ntev dua, cov tawv nqaij ntawm cov plaub hau tuab dua thiab thicker. Raws li cov tawv nqaij Kiln txuas ntxiv mus ua tuab, qhov chaw ntawm cov tawv nqaij Kiln txuas ntxiv, thiab cov khoom siv viscosity txuas ntxiv, thiab cov khoom uas tuav nws kuj txo qis. Nyob rau tib lub sijhawm, vim lub ntiajteb txawj nqus ntawm daim tawv Kiln ntawm cov khoom sib txhuam thiab cov khoom siv tshuab hluav taws xob thiab yuav luag sib npaug, yog li cov tawv nqaij ntawm ib qho tuab tuab.
Kev sib raug zoo ntawm cov khoom siv refractory thiab cov tawv nqaij ua tiav
Ua ntej, tshuaj pleev cov ntxhia pob zeb, porosity thiab firosness thiab cov tshuaj tiv thaiv uas tsim tau yooj yim rau cov khoom siv hluav taws xob, thiab cov tshuaj yeeb dej caw li cas tom qab cov tshuaj tiv thaiv nrog cov khoom siv refactory. Yog li ntawd, nws txiav txim siab seb cov khoom siv refript yog "hws" thiab seb puas yooj yim rau daim ntawv Mem cem Clinker los ua cov tawv nqaij Kiln.
Thib ob, cov tshuaj lom neeg muaj pes tsawg leeg, theem sib xyaw ua ke thiab cov khoom siv lub cev ntawm cov npoo av refractory tau hloov vim yog qhov kub thiab cov yaig ntawm clinker. Piv txwv li, magnesia {{{}} xob hlau spinel refractory r ribs thiab ferrroalumina spinel cib muaj ntau npaum li cas ntawm FE2O3 los pab hlawv. Yog hais tias cov tawv nqaij kiln tsis tuaj yeem tsim tau sai sai, qhov kev sib tw ua kom pom tseeb ntawm cov hluav taws xob ua kom pom tseeb, thiab kev nce qib hauv qhov kev nthuav dav los ntawm kev puas tsuaj los ntawm kev puas tsuaj los ntawm thermal poob siab. Thib peb, cov yam ntxwv ntawm cov cement Clinker {10} ement reaction reaction {} {{alieces- al} alumina rectractories yog c2s. C2S muaj qhov ua tau ntawm theem hloov thiab pulverization. Ntawm peb lub ntsiab ntawm CR, AL thiab FE, tsuas yog CR tuaj yeem ruaj khov. Yog li no, dolomite bricks muaj qhov zoo tshaj plaws Kiln cladding kev ua yeeb yam, ua raws los ntawm Magnesia Alumina Clock muaj qhov tsis zoo tshaj plaws Kiln cladding kev ua tau zoo.
