Dab tsi refractory castable yuav tsum tau siv rau kiln hauv ob sab phlu ntawm 1300 degree?
Qhov kev xaiv ntawmrefractory castablesThaum lub qhov cub hauv ob sab phlu kub yog 1300 degree nyob ntawm qhov sib txawv rauv hom thiab sib txawv rauv hauv ob sab hauv cov cua. Tsis muaj teeb meem dab tsi yog xaiv cov khoom siv, lub hom phiaj kawg yog kom txuag tau lub zog thiab txo kev siv, ua tiav kev siv tau zoo thiab muaj lub neej ua haujlwm ntev.
1. Xav txog cov roj siv los ntawm lub qhov cub
Ua ntej xaiv, koj yuav tsum xub xav txog cov roj siv nyob rau hauv lub cub tawg, cov khoom nruab nrab ntawm cov khoom raug rho tawm haujlwm, thiab cov degree thiab qhov xwm ntawm corrosiveness ntawm cov khoom raw khoom. Puas yog acidic lossis alkaline? Tsis tas li ntawd, muaj lwm yam tseem ceeb los xav txog xws li lub tshuab hluav taws xob hom, seb puas muaj kev yaig thiab hnav los ntawm cua ceev thiab cov neeg kho tshuab kev ntxhov siab, thiab cov txheej txheem combustion.
2. Kev tiv thaiv hluav taws thiab kev ua haujlwm kub yog qhov tseem ceeb heev
Lub qhov cub kub ntawm 1300 degree yog qhov kub ntawm qhov hluav taws kub, tsis yog qhov kub thiab txias. Lub ntsiab txhais ntawm refractory degree thiab kev khiav hauj lwm kub yog ib qho tseem ceeb heev. Feem ntau,siab alumina refractory castablestuaj yeem siv rau qhov cub kub ntawm 1300 degree. Tam sim no, tag nrho cov high-aluminium castables yog siv. Yeej, cov ntaub ntawv uas tsis tshua muaj cement yog siv, tab sis yog tias qhov kev yaig yog qhov hnyav, cov khoom siv acidic lossis alkaline corrosion-resistant yuav tsum tau xaiv raws li qhov kev yaig. Yog tias nws yog acidic corrosion, koj tuaj yeem xaiv cov iav dej los yog phosphoric acid-bonded refractory castable. Yog tias nws yog alkaline corrosion, koj tuaj yeem xaiv cov khoom hnav-tiv taus thiab magnesium refractory castable. Cov khoom siv siab hnav-tiv taus ntxiv nrog silicon carbide, uas tuaj yeem tiv taus yaig thiab ua lub luag haujlwm. Hnav tsis kam. Thaum xaiv cov khoom siv magnesium, kev saib xyuas yuav tsum tau them rau cov teeb meem ntawm cov dej noo thiab cua siab nyob rau hauv lub qhov cub hauv ob sab phlu.
3. Kev tsim kho txuas kuj tseem ceeb heev
Tom qab xaiv high-aluminium refractory castables, txoj kev tsim kho kuj tseem ceeb heev, vim hais tias cov xaiv high-aluminium castables kuj muab faib ua ntau qib zoo. Yog tias qhov kev teeb tsa thaum ntxov sai dhau lawm, nws yuav yog qhov kev tswj xyuas qhov sib piv ntawm binder thiab micro hmoov tsis tsim nyog. Yog hais tias nws yog tus nqi ntawm cov cement Ntxiv ntau dhau yuav tsis tsuas yog ua rau cov teeb meem ceev ceev, tab sis kuj ua rau lub zog tom qab ntawm high-aluminium refractory castable raug cuam tshuam.
Yog hais tias lub high-aluminium castable solidifies qeeb heev, kev tsim kho kub yuav tsum tau xav txog. Thaum ntxiv dej, tus nqi yuav tsum tau tswj. Thaum qhov kub thiab txias qis, cov dej haus yuav tsum tau rhuab mus rau 30 degree, thiab tom qab ntawd tov nrog cov khoom ua ntej siv. Yog tias nws txhaws hauv 40 feeb. Tom qab ntawd ci raws li qhov tsim nyog ci ci tuaj yeem ua kom lub neej ua haujlwm ntawm high-aluminium refractory castables.
