Rwb thaiv tsev Mullite Castable
Khoom Description
Insulating mullite castables qhia
Raws li lub teeb yuag, kev ua haujlwm siab ntawm cov khoom siv hluav taws xob rau cov khoom siv kub kub, lub teeb yuag mullite castable muaj qhov ntom ntom ntom, feem ntau yog nyob nruab nrab ntawm 600-1200kg / m3, thiab feem ntau yog tsim los ntawm mullite, refractory cement, Ua los ntawm refractory khoom, additives thiab lwm yam auxiliaries.
Mullite yog cov ntxhia uas tsis tshua muaj lub ntiajteb txawj nqus, siab porosity thiab zoo thermal rwb thaiv tsev, thiab feem ntau yog siv los tsim cov khoom siv refractory. Refractory cement thiab refractory hmoov yog siv los txhim kho lub zog thiab ua haujlwm ntev ntawm cov khoom, thaum cov khoom ua npuas ncauj siv los tsim cov pores hauv cov khoom, yog li txo qhov ntom thiab thermal conductivity ntawm cov khoom. Lwm yam additives, xws li polymers thiab cellulose, yuav siv tau los txhim kho lub fluidity thiab tawg tsis kam ntawm cov khoom.

Khoom nta
1. Tsawg ntom ntom: Vim muaj qhov sib ntxiv ntawm cov av nplaum thiab lwm yam khoom siv, qhov ntom ntawm mullite castable yog me me, txo qhov hnyav ntawm cov khoom.
2. Zoo kub tsis kam: Mullite yog cov khoom siv refractory nrog kev ua haujlwm kub zoo heev thiab tuaj yeem tswj xyuas lub cev thiab tshuaj lom neeg zoo ntawm qhov kub thiab txias.
3. Tsawg thermal conductivity: Lub thermal conductivity ntawm lub teeb yuag insulating mullite castable yog tsawg, uas muaj txiaj ntsig zoo rau kev txhim kho thermal efficiency ntawm cov khoom siv.
4. Muaj zog corrosion kuj: Vim yog cov khoom zoo heev ntawm mullite, lub teeb yuag mullite castables muaj corrosion kuj zoo thiab tuaj yeem hloov mus rau ntau qhov chaw hnyav.
Cov txheej txheem tsim khoom
Insulating mullite castable yog cov khoom siv refractory npaj nrog mullite ua lub ntsiab sib sau ua ke thiab tsim nyog tus nqi ntawm cov av nplaum, alumina, silica hmoov thiab lwm yam ntaub ntawv. Nws cov txheej txheem npaj feem ntau suav nrog cov kauj ruam hauv qab no:
1. Cov khoom xyaw: Nyhav ntau yam raw khoom raws li ib qho kev faib ua feem, xws li mullite, lub teeb av nplaum, alumina, silica hmoov, thiab lwm yam.
2. stirring: Muab cov khoom hnyav hnyav rau hauv ib rab diav, ntxiv cov dej uas tsim nyog, thiab do rau hauv ib qho sib tov sib xyaw.
3. Pouring: Ncuav qhov sib tov rau hauv pwm thiab kho nws ib txwm nyob hauv chav sov.
4. Demoulding: Tom qab cov castable qhuav tag, demould kom tau cov khoom tiav.
Cov khoom siv
1. Kev lag luam hlau: Insulating Mullite castable siv los tsim cov blast furnaces, kub blast furnaces, cua sov rauv thiab lwm yam ntaub ntawv refractory.
2. Kev lag luam hlau tsis-ferrous: siv los tsim aluminium smelting furnaces, zinc smelting furnaces thiab lwm yam khoom siv.
3. Kev lag luam tshuaj: siv los tsim cov tshuaj tiv thaiv pej thuam, cov khoom siv hluav taws xob thiab lwm yam khoom siv.
4. Ceramic kev lag luam: siv los tsim kilns, cov menyuam kilns thiab lwm yam khoom siv.
5. Lwm cov kev lag luam: siv los tsim cov iav rauv, txiv qaub kilns thiab lwm yam khoom siv.
