Lub Luag Haujlwm Tseem Ceeb ntawm Cenospheres hauv Cov Cib Refractory Uas Muaj Qhov Sib Nqus: Kev Ua Hluav Taws Xob Siab (Txog 1730 ° C) & Kev Txuag Hluav Taws Xob Tseem Ceeb

Cov lus tseem ceeb hauv lub npe: cenospheres, cov cib refractory insulating lightweight, refractoriness, energy savings

Thaum kev txuag hluav taws xob thiab kev tsim khoom ntsuab ua qhov tseem ceeb tshaj plaws hauv kev lag luam kub siab, kev xaiv cov khoom siv refractory uas pheej yig yog qhov tseem ceeb dua puas tau. Cenospheres - sib dua, cov khoom siv ceramic microspheres - ua lub luag haujlwm tseem ceeb hauv kev tsim khoomcov cib refractory uas tsis hnyav thiab tsis yooj yim tawg, ua tsaug rau lawv cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb.

Kev Ua Haujlwm Zoo Tshaj Plaws Txog Tshuaj Lom Zem & Kev Ua Kub: Al₂O₃ 30%–40%, Kev Ua Kom Tsis Kub 1650°C – 1730°C

Lub neej ua haujlwm thiab kev nyab xeeb ntawm cov ntaub ntawv refractory feem ntau nyob ntawm lawv cov tshuaj lom neeg. Cov Cenospheres muaj cov oxides uas yaj sai heev, nrog raualumina (Al₂O₃) cov ntsiab lus feem ntau yog li ntawm 30% txog 40%Ua tsaug rau qib alumina siab no, cenospheres ua rau muaj kev tiv thaiv kub siab, ua tiav arefractoriness ntawm 1650 ° C txog 1730 ° C.

Qhov kev tiv taus hluav taws xob zoo no ua kom ntseeg tau tias cov cib hluav taws xob rwb thaiv tsev uas ua los ntawm cenospheres tseem ruaj khov thiab tswj lawv cov kev ua haujlwm rwb thaiv tsev txawm tias nyob rau hauv qhov chaw kub tshaj plaws - zoo tiv taus kev poob siab thermal thiab tiv thaiv cov qauv kiln.

Cov Txiaj Ntsig Tseem Ceeb: Kev daws qhov teeb meem "Lightweight vs. High Performance"

Piv rau cov cib refractory hnyav ib txwm muaj lossis cov cib insulating feem ntau, cov cib refractory insulating lightweight uas ua los ntawm cenosphere muaj ntau yam txiaj ntsig zoo:

1. Cov yam ntxwv zoo kawg nkaus uas tsis hnyav- Cov qauv hollow, nyias-phab ntsa ntawm cenospheres txo qhov ntom ntawm cov cib tiav lawm. Qhov no txo ​​qhov hnyav ntawm cov qauv hlau kiln, ua kom yooj yim rau kev tuav thiab kev teeb tsa, thiab ua rau cov phab ntsa kiln nyias dua yam tsis muaj kev cuam tshuam rau kev rwb thaiv tsev.
2. Tus nqi tsim khoom qis dua- Cov cenospheres tau rov qab los ntawm cov tshauv ya ntawm cov chaw tsim hluav taws xob uas siv thee, ua rau cov khoom siv raw muaj dav thiab pheej yig. Kev siv cenospheres txo cov nqi khoom siv tag nrho thaum txhawb kev siv cov khoom lag luam rov qab.
3. Kev txuag hluav taws xob tseem ceeb- Ua tsaug rau qhov zoo heev thermal rwb thaiv tsev ntawm cenospheres, cov cib ua tiav muaj cov thermal conductivity qis heev. Cov ntaub ntawv hauv daim teb qhia tau hais tias thaum cenosphere cib siv rau hauv cov cub tawg tiv taus cua sov hauv kev lag luam tshuab,kev txuag hluav taws xob tuaj yeem ncav cuag 30%nyob rau hauv lub thawv-hom tsis kam rau lub cub tawg,kev txuag nyiaj yuav siab txog li 54%.
4. Lub neej ua haujlwm ntev dua– Cov cib Cenosphere sib xyaw ua ke lub zog kho tshuab zoo nrog rau cov qauv kaw-cell ntawm cov spheres, muab kev tiv thaiv thermal shock thiab kev tiv thaiv spalling zoo heev. Qhov no txhais tau tias lub neej ua haujlwm ntev dua hauv cov chaw ib puag ncig hnyav xws li metallurgical, tshuaj lom neeg, iav, thiab cement rotary kilns.

Txhim Kho Koj Cov Qauv Cib Refractory nrog Cov Cenospheres Zoo

Yog tias koj yog tus tsim cov cib refractory uas tsis hnyav thiab xav txhim kho koj cov khoom ua haujlwm - txo qhov hnyav, txiav cov nqi hluav taws xob, thiab txuas ntxiv lub neej ua haujlwm - qhov zoo ntawm koj cov khoom siv raw tseem ceeb.

Peb yog ib lub tuam txhab kev tshaj lij ntawmcov cenospherenrog cov tshuaj lom neeg ruaj khov (Al₂O₃ 30% –40%) thiab kev tiv taus hluav taws xob tas li (1650 ° C – 1750 ° C). Peb cov cenospheres tuaj yeem koom ua ke ncaj qha rau hauv koj cov qauv cib kom ua tiav cov txiaj ntsig tau piav qhia saum toj no.
