Yuav ua li cas los tsim high alumina bricks?

High-alumina cib linings tau muab faib ua plaub pawg raws li qhov loj ntawm cov pob qij txha cib thiab cov degree ntawm kev ua haujlwm zoo. Cov qeb thiab qhov loj ntawm cov pob qij txha cib yog raws li: Ⅰ ≤0.5mm; Ⅱ ≤1mm; Ⅲ ≤2mm; Ⅳ ≤ 3mm. Cov av nkos hluav taws yuav tsum muaj tag nrho hauv cov pob zeb sib txuas ntawm cov pob zeb cib, thiab cov pob zeb cib ntawm sab hauv thiab sab nrauv ntawm cov txheej sab sauv thiab sab hauv yuav tsum tau staggered.

Cov hauv paus ntsiab lus hauv qab no yuav tsum tau ua raws thaum npaj cov av nkos refractory rau bricklaying.

2.1 Ua ntej bricklaying, ntau yam refractory slurries yuav tsum tau pre-sim thiab pre-built los txiav txim lub sij hawm sib txuas, pib lub sij hawm, sib xws thiab dej siv ntawm txawv slurries.

2.2 Cov cuab yeej sib txawv yuav tsum tau siv los npaj cov av nkos sib txawv thiab ntxuav hauv lub sijhawm.

2.3 Cov dej huv yuav tsum tau siv rau kev npaj cov av nkos zoo sib txawv, cov dej yuav tsum raug ntsuas kom raug, thiab kev sib xyaw yuav tsum zoo ib yam, thiab siv raws li qhov xav tau. Cov av nkos hydraulic thiab huab cua-hardening av uas tau npaj yuav tsum tsis txhob siv nrog dej, thiab cov av nkos uas tau npaj ua ntej yuav tsum tsis txhob siv.

2.4 Thaum npaj cov phosphate-bound av nkos, xyuas kom meej lub sij hawm daig, thiab kho nws raws li koj siv. Cov av nkos npaj yuav tsum tsis txhob diluted nrog dej arbitrarily. Vim nws qhov xwm txheej corrosive, cov av nkos no yuav tsum tsis txhob cuam tshuam ncaj qha nrog lub plhaub hlau.
