Dab tsi ntawm refractory castable yog haum rau 1300 degree rauv hauv ob sab phlu? nws yog ua raws li cov txheej txheem sib txawv ntawm cov cua sov sib txawv, txawm tias cov khoom siv twg yog xaiv, lub hom phiaj kawg yog kom txuag tau lub zog thiab txo kev noj, kom ua tiav cov txiaj ntsig siv thiab kev pabcuam ntev.
Ua ntej xaiv, peb yuav tsum xub xav txog cov roj siv los ntawm lub qhov cub, cov khoom siv raw nruab nrab ntawm cov khoom raug rho tawm haujlwm, thiab qib corrosiveness thiab qhov xwm txheej ntawm cov khoom siv raw khoom, puas yog acidic lossis alkaline? Tsis tas li ntawd, muaj lwm yam tseem ceeb los txiav txim siab txog lub tshuab hluav taws xob hom, seb puas muaj cua ceev, kev ntxhov siab ntawm cov khoom siv los ntawm kev yaig hnav, thiab tom qab ntawd hom combustion.
Lub qhov cub kub ntawm 1300 degree yog qhov kub ntawm qhov hluav taws kub, tsis yog hluav taws kub, lub ntsiab lus ntawm qhov hluav taws kub thiab kev siv kub yog qhov tseem ceeb heev, nyob rau hauv ib txwm muaj xwm txheej, kev xaiv ntawm aluminium castable siab tuaj yeem yog 1300 degree. Rauv kub, tam sim no siv high aluminium castable yog siv cov chav kawm qis cement, tab sis yog tias qhov kev yaig loj heev, nws yog qhov yuav tsum tau ua raws li qhov kev yaig, xaiv cov kua qaub lossis alkaline cov khoom uas tiv taus yaig. Yog tias nws yog acid yaig, tuaj yeem xaiv cov iav dej los yog phosphate bonded castable, yog tias nws yog alkaline erosion tuaj yeem xaiv qhov siab abrasive thiab magnesium castable, siab abrasive kuj ntxiv rau silicon carbide, tuaj yeem tiv taus yaig thiab hnav. Kev xaiv cov khoom siv magnesium yuav tsum tau them sai sai rau cov dej thiab cua siab ntawm lub qhov cub hauv ob sab phlu.
Tom qab xaiv thiab siv high aluminium castable, cov txheej txheem kev tsim kho kuj tseem ceeb heev, vim hais tias qhov kev xaiv siab aluminium castable kuj tau muab faib ua ntau theem zoo, yog tias qhov kev sib xyaw ua ke thaum ntxov yog ceev heev, nws yuav tsis tsim nyog tswj qhov sib piv ntawm binder thiab micro-hmoov. , yog hais tias tus nqi ntawm cov cement yog loj heev, tsis tsuas yog cov teeb meem ceev ceev condensation, tab sis kuj ua rau lub zog lig ntawm high aluminium castable yuav raug cuam tshuam.
Yog hais tias lub siab aluminium castable condenses qeeb heev, qhov kev tsim kho kub yuav tsum tau txiav txim siab, thiab cov dej yuav tsum tau tswj xyuas thaum ntxiv dej. Thaum qhov kub thiab txias qis, cov dej haus yuav tsum tau rhuab mus rau 30 degree, thiab cov khoom yuav tsum tau tov thiab nplawm ua ntej siv. Yog tias nws teem rau hauv 40 feeb. Tom qab ntawd ci raws li qhov tsim nyog ci ci tuaj yeem ua kom lub neej ua haujlwm siab ntawm aluminium castable.
