Av nplaum kub-insulating refractory breaks xa mus rau lub teeb cov khoom siv hluav taws xob refractory muaj 3}}}}}% al2o3. Av nplaum kub-insulating breaks Siv cov av nplaum clinker lossis lub ntsej muag yas ua cov ntaub ntawv yas. Lawv siv cov av nplaum, cov ntoo ntab, refractory clink clinker, thiab ntxiv binders thiab sawdust. Tom qab kev sib tua, sib xyaw, molding, kom qhuav thiab hluav taws kub, lawv tuaj yeem tsim cov khoom lag luam nrog lub ntim ntom ntom ntawm {12 txog 1.5 g / cm '. Feem ntau, cov txheej txheem sib txuas ua ke yog siv rau kev tsim khoom, thiab cov qauv ua npuas ncauj kuj tseem siv tau los ua ib qho qauv pacous. Cov khoom xyaw xyaw nrog dej los ua cov av nkos yas lossis av nkos, uas yog extruded lossis pov rau hauv pwm. Tom qab ziab, nws raug rho tawm haujlwm hauv oxidizing huab cua ntawm 125 0 rau 1350c. Qhov ntim ntom ntom ntawm cov av nplaum uas siv tau siv tau yog 0.75 rau 1.50 g / cm3, thiab lub compressive muaj zog yog 2. {}. 9 mpa. Av nplaum kub-insulating breaks tau siv dav, tsuas yog siv los ua cov ntaub ntawv tsis muaj cua sov, thiab qhov ntsuas kub yog 1200 ~ 1400C. Raws li Suav cov qauv (GB} 24}}}}}. 3, ng {}. 0, ng {44}}. 9, Ng {{{-0. 8N {38}. 7, ng {}. 6 Thiab kaum lwm qib raws li lub ntim ntom ntom.

 

Cov txheej txheem siv ntau lawm rau cov av nplaum insulating rectractory refractory refroting ntxiv cov qauv nrog cov qauv ua npuas dej kuj tseem siv tau.

Cov ntaub ntawv raw, binders thiab sawdust rau av nplaum-raws li cov ntaub ntawv rawractory (1) cov khoom siv romactory (1) clay clinker thiab pob zeb nplaub. Cov tshuaj lom neeg muaj kuab lom ntawm cov hlaws dai fackedates heev. Txhawm rau kom tau txais cov khoom lag luam uas ua tau raws li cov qauv zoo, nws yog ib qho tsim nyog los xaiv cov khoom nyoos rau cov av nplaum nrog 3%, thiab kev ua kom zoo dua 31 {{}}} degree. Feem ntau ntawm cov bloating beads raug kaw hollow spheres nrog nyias phab ntsa thiab lub zog siab. Lawv lub ntim ntom ntom yog 0.38 ~ 0.44gcm ', lawv cov xim yog greyish dawb, thiab lawv cov particle loj yog 20 ~ 250μm muaj ntau ntxiv. Tag nrho cov nqi khoov tau ntau dua 95%. Cov suav nrog tuaj yeem raug tshem tawm los ntawm kev soj ntsuam lossis yaug. Yog hais tias yaug, lawv yuav tsum tau qhuav lossis spun. (2) Clinker nplua thiab ntab hlaws yog ob qho tib si ntshiv. Cov hlaws ntab yog puag ncig lossis ze li ntawm thaj chaw du, thiab thaj chaw muaj thaj chaw tshwj xeeb, uas yuav tsum muaj cov cuab yeej khi. Cov av nplaum tseem ceeb yog: Sulfite pulp khib nyiab ua kua, txhuas sulfate, dextrin resin, thiab lwm yam kev khi lus ntau, kev ua kom muaj zog yas, cov khoom siv roj hmab yas. Nws kuj tseem pheej yig thiab muaj ntau yam khoom siv. Yog li ntawd, feem ntau sib xyaw yog raws cov av nplaum refractory. Raws li cov khoom lag luam, kev ntom ntom ntom thiab kev xav tau kev ua haujlwm, ntxiv cov khoom siv organic tsim nyog lossis inorganic. (3) Sawdust yuav tsum tau tshuaj ntsuam thiab cov particle loj yuav tsum tsawg dua 1-2 hli.

Cov khoom xyaw rau av nplaum kub-insulating rectractory lub ntim ntom ntom ntawm cov khoom lag luam yog txawv, thiab tus nqi ntawm cov khau raj hauv qab kuj sib txawv. Feem ntau, nws hloov ntawm 10% thiab 70%. Qhov me me ntim ntom ntawm cov khoom, nws tau ntxiv. Ntxiv ib co av nplaum clinker hmoov rau cov khoom xyaw kom txo tau lub ntim shrinkage tshwm sim los ntawm kev deformation ntawm cov khau khiab ntab. Txhawm rau kom txo cov nqi ntawm cov roj hauv qab, txhim kho lub zog ntawm cov khoom lag luam semi-tiav thiab txo cov shrinkage tom qab tua hluav taws, ntxiv tus nqi tsim nyog ntawm sawdust.

Kev sib xyaw ntawm cov av nplaum-raws li cov pob taws kub ua kom cov khoom siv noo noo ua rau cov khoom siv noo noo sib xyaw uayees thiab txhim kho cov moulding ua haujlwm ntawm av nplaum. Feem ntau siv cov khoom siv sib xyaw ua ke suav nrog xuab zeb mixers thiab yuam tawm cov tshuaj sib xyaw. Muaj ob txoj kev ua haujlwm: ib qho yog ntxiv cov pas dej ntab, sawdust, binder, dej, av nplaum thiab clinker hmoov nyob rau hauv kev txiav txim. Sib tov rau 5 txog 6 feeb kom tau txais cov av nplaum cov khoom nrog cov pob ntoo ntab, binder raws li txheej txheej sab nraud, thiab hmoov qhuav li txheej txheej sab nraud. Lwm tus yog kom ntxiv cov khau khiab ntab, cov av nplaum clinker, sib dhos rau hauv lub tshuab, sib tov rau 2 feeb, thiab ntub sib xyaw, thiab ntub tov rau 3 mus rau 4 feeb. Cov av nplaum sib xyaw tuaj yeem ua pwm tom qab 12 txog 24 teev. Cov dej noo cov ntsiab lus ntawm cov av nplaum nyob ntawm seb cov khoom ntim ntom ntom ntom nti, cov tshuaj sib piv, thiab moulding txheej txheem. Feem ntau, cov ntsiab lus noo ntawm cov av nplaum yog 20% ​​mus rau 30%.

Qhov kev sib sau ntawm av nplaum kub-insulating breaks feem ntau ua los ntawm tes thiab tshuab nias. Tshuab nias yuav tsum siv 150 ~ 300Kh cib tshuab. Lub zog ntawm cov cib tom qab kev sib sau yog tsawg heev, yog li lawv yuav tsum tau daws nrog kev saib xyuas; Semi-tiav cov khoom lag luam nrog cov duab nyuaj, qhov loj me me tuaj yeem tuav nrog pallets lossis plywood kom tiv thaiv cov cib los ntawm deformation thiab kev puas tsuaj.

Cov ntim thiab hluav taws kub ntawm av nplaum kub-insulating breaks yog sab-thau khoom yog sab nrauv, qhov chaw ruaj khov thiab cov txhuv, thiab cov txhuv muaj txheej los ntawm txheej. Tes cov khoob yuav tsum tau sab laug ntawm cov thwv cib. Lub Kiln loading qhov siab yog feem ntau yog 1.5 ~ 1.8m, thiab cov khoom siv nrog ntau dua {}}. Thaum cov khoom raug rho tawm haujlwm nyob rau hauv ib qho kev rho tawm ntawm kev poob qis lossis cov tuab kiln, qhov kub thiab txias yuav tsum hnav khaub ncaws. Qhov ntau tshaj plaws hluav taws kub sib txawv nyob ntawm qhov zoo ntawm cov khau khiab ntab, av nplaum thiab lub ntim ntom ntawm cov khoom. Feem ntau, cov khoom lag luam nrog bulk ceev ntawm {{}}. 4 ~}}}}}}}}} {21}} degree; Cov khoom lag luam tsis sib xws ntawm 0.8 ~ Qhov txias txias kiln ceev yog zoo li cov ntawm av nplaum cib. Hauv kev tsim khoom tiag tiag, cov khoom lag luam nrog cov sib txawv sib txawv feem ntau raug rho tawm haujlwm hauv tib lub Kiln. Yog li ntawd, raws li qhov ntsuas kub nyob hauv Kiln, cov khoom lag luam ntawm cov hom sib txawv tau teeb tsa hauv ntau qhov chaw los txhim kho lub hluav taws zoo.

Av nplaum kub-insulating breaks tau siv dav, feem ntau nyob rau hauv tshav kub rwb thaiv tsev txheej ntawm cov khoom cua sov thiab muaj rauv. Lawv tuaj yeem siv rau hauv thaj chaw tsis muaj kev yaig thiab scouring ntawm cov khoom siv kub siab molten. Qee qhov chaw nyob rau hauv kev sib chwv nrog cov nplaim taws nrog cov txheej txheem refracion los txo cov roj yaig los ntawm cov roj tawg thiab cov plua plav los ntawm cov dej sov thiab plua plav. Kev ua haujlwm kub ntawm cov khoom lag luam tsis tshaj qhov ntsuas kub ntawm qhov hloov pauv ntawm kab.
