Alumina Insulating Re-Fractory Cib

Alumina insulating refractory cib muaj cov yam ntxwv ntawm kev muaj zog tiv taus acid thiab alkali cua, muaj zog tiv thaiv kom txo tau, thiab zoo thermal shock kuj. Nws tuaj yeem siv tau ntev hauv qab 1700 degree. Thaum xyoo 1960, Tuam Tshoj pib tsim cov khoom lag luam Al2O3 nrog cov ntsiab lus ntawm 90% mus rau 92% los ntawm txoj kev ua npuas dej. Txij li thaum xyoo 1980s, ntau lub chaw ua haujlwm refractory tau tsim cov khoom lag luam nrog cov ntsiab lus Al2O3 ntau dua 90% los ntawm cov txheej txheem hlawv tawm ntxiv. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, ntau cov thev naus laus zis tseem niaj hnub txhim kho kom zoo dua rau cov neeg siv khoom thiab kho raws li cov neeg siv khoom xav tau. Cov ntaub ntawv refractory kuj tau tshwm sim hauv ntau hom, haum rau ntau lub sijhawm, pab tib neeg lub neej.
