Aluminate Mement Refractory Castables muaj ntau ntau yam, nrog cov qauv sib txawv, kev tsim kho thiab cov kev tsim kho thiab cov yam ntxwv cuam tshuam rau kev ua tau zoo, yeej zoo ib yam.
Kom muaj nuj nqis ntawm Maas
Cement yog ib qho ntawm cov khoom tseem ceeb ntawm cov khoom siv ua kom muaj zog, uas yog cov khoom tseem ceeb los txiav txim lub zog thiab tseem cuam tshuam lwm cov khoom. Ntau yam sib txawv ntawm cov cement thiab nws cov tshuaj muaj cov teebmeem sib txawv ntawm kev ua tau zoo.
Ca -50 Maas high alumina Refractege Cibration, nws cov kev sib sau ua ke muaj nyob hauv lub rooj 1 .30, ntxiv rau 10% dej. Los ntawm lub rooj, nrog kev nce ntawm cov kev ua kom haum, chav sov compressive lub zog, lub tshuab hluav taws xob tau txo qis, thiab cov kab tom qab tua hluav taws nce ntxiv. Qhov no yog vim lub siab impurity cov ntsiab lus ntawm ca -50 Mentse ua kua hauv nws cov khoom siv cua sov hauv cov khoom cua kub ntau dua, ua rau muaj kev poob qis. Yog li ntawd, nyob rau hauv cov xwm txheej ntawm kev ua kom muaj zog ntawm chav tsev ntawm chav sov, cov tshuaj} kev ua tau zoo los txhim kho qhov kub thiab txias ntawm refractory castabertables. Thaum txo cov hmoov nplej siab, cov hmoov nplej regraction kom zoo, thiab cov hmoov nplej regractive kom tau txais qhov siab tshaj plaws ntawm kev sib xyaw. Feem ntau siv cov cement noj yog 10-15 tauj ib xees.

Kev Siv Dej
Ntau yam sib txawv ntawm cov neeg txawv teb chaws seem tau siv los ua los tsim cov refractory castubtab. Tib yam ntawm cov xis mas kuj tseem tuaj yeem tsim rau ntau hom kev ua kom rov ua cov khoom siv refractory. Nyob rau hauv refractory castable faib thiab cov txheej txheem cov txheej txheem zoo ib yam, cov dej ntawm Refractory Castable kev ua yeeb yam cuam tshuam yog tib yam. Tam sim no noj Ca -50 Maas high alumina refractory castables, raws li cov hmoov ntawm nws cov hmoov av, raws li tag nrho cov alumary clinker, aggregate yog<15mm 70% of the total material, powder and cement is 15% each. The mould was dismoulded after the initial setting of the moulding with moist curing for 1d, and then standard curing was carried out23 to check the various properties.
Raws li pom los ntawm lub rooj, cov castables nrog kev nce ntawm cov dej, ntau yam uas muaj zog ntxiv txo qis dua li 40%, lub zog kub ntxiv txo qis los ntawm 57% lossis li ntawd; loaded softening kub txo los ntawm 14001 txog 12501, post-hlawv kab hloov los ntawm {}}. 96g / cm3 mus rau 2.17g / cm3. Qhov no txhais tau tias, thaum tsim aluminate Mement Mement Refractory castables, cov dej ntws (lossis dej-xiss piv) xaiv yog qhov tseem ceeb heev. Thaum cov dej muaj ntau dua, tom qab dej cua dim, cov qauv siv xoob, ua rau ntau yam ntawm cov khoom kom txo tau tag nrho. Yog li ntawd, nyob rau hauv cov xwm txheej ntawm kev ua kom yooj yim ntawm kev tsim kho, cov dej hauv kev sib tov yuav tsum tau txo kom ntau li ntau tau. Nyob rau hauv lub premise tsis yog tov dej-txo dej, tus nqi dej uas tsim nyog rau Alumination Refractory casles yog 10% ~ 13%.

Nws yuav tsum tau taw qhia tias nyob rau hauv Refractory castable faib ua feem thiab cov dej muaj txiaj ntsig, xws li cov dej muaj txiaj ntsig, thiab lwm yam dej tshaj li cov dej, qhov zoo tshaj plaws ntawm kev ua tau zoo. Yog li ntawd, thaum kev tsim kho ntawm Aluminate Mement Mement Refractory castables cas, piv qhov loj me ntawm lub zog, thiab tom qab ntawd nws tuaj yeem tsim tawm thiab txua ntoo.
Refractory Hmoov
Aluminate Maasing Refractory castable yog feem ntau tov nrog haum refract neeg hmoov av, nws lub luag haujlwm:
(1)Txo cov nyiaj kom tsawg, tuaj yeem txo tus nqi thiab txhim kho kev siv ntsuas kub;
(2) Refractory hmoov tuaj yeem ua lub luag haujlwm ntawm qhov tsis muaj teeb meem, kub thiab tuaj yeem koom nrog kev tawm tsam kub, txhim kho kev ua haujlwm ntawm refractory;
(3)Refractory oxides ntawm ultra-nplua hmoov sib xyaw, ua kom muaj qhov kub hnyav, yog li nws tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv cas. Refractory hmoov ntau yam, zoo heev thiab nws cov nqi, yog qhov tseem ceeb cuam tshuam rau kev ua tau zoo ntawm cov khoom siv.
Hauv Ca -50 Mement Refractory castable, ntsig txog, nrog kev sib tw qub, kev siv ntsuas kub tuaj yeem nce txog li 100 degree; A-al2o3 hmoov ntawm lub zog ntawm elecina Maas Refractory castable zog, qhia hauv daim duab 1.

Lub txiaj ntsig ntawm hmoov refractal ncaj qha cuam tshuam lub zog, ceev ntom thiab porosity ntawm refractory caster. Feem ntau hais lus, cov hmoov nplej refractory, qhov zoo dua kev ua tau zoo ntawm cov refractory castable; Thaum kev siv cov hmoov ultra nplua hloov ntawm cov hmoov av refract, qhov muaj qhov hws pom kev txo qis, thiab lub zog txhim kho.
Daim duab 2 qhia txog cov hmoov ntawm hmoov tshuaj rau kev ua haujlwm ntawm cov khoom siv. Cov cement ntawm Refractory Casab yog 14%. Raws li pom hauv daim duab, muaj ib qho txiaj ntsig zoo ntawm cov hmoov av refractory; Ntawd yog, 15% {3}}%, qhov kev ntig ntom nti yog qhov loj, thiab lub zog compressive zoo dua nyob rau hauv chav tsev kub thiab 1350 degree tom qab hlawv. Thaum cov hmoov nplej rosage yog me me, thiab tus nqi ntawm xis mas, tsis txaus los qhwv cov kev tswj hwm kev ua haujlwm, yog li kev ua haujlwm txo qis; Thaum tus nqi ntawm kev refractory hmoov ntau yog ntau dua tus nqi ntawm cov dej xis, ua kom muaj qhov nce ntxiv, ua kom muaj qhov ua kom tau txo qis.
