Daim ntawv thov qhov chaw thiab qhov yuav tsum tau muaj ntawm High Alumina cib nyob rau hauv kub tawg qhov cub

Blast furnace ironmaking kub moj tej tawg qhov cub yog ib qho tseem ceeb core kiln nyob rau hauv cov txheej txheem hlau. High alumina bricks, raws li cov khoom tseem ceeb ntawm cov ntaub ntawv refractory, yog dav siv nyob rau hauv kub blast qhov cub. Vim qhov kub thiab txias sib txawv ntawm qhov nruab nrab ntawm qhov kub thiab txias qhov cub, cov khoom siv refractory siv nyob rau hauv txhua ntu sib txawv heev. Cov cheeb tsam tseem ceeb uas siv cov alumina cib siab muaj xws li kub blast furnace vault chaw, phab ntsa loj, regenerators, combustion chambers, thiab lwm yam cov ntsiab lus raws li nram no:

1. Dome

Lub vault yog qhov chaw txuas nrog lub combustion chamber thiab lub regenerator, nrog rau cov txheej txheem ua hauj lwm ntawm bricks, txheej filling thiab rwb thaiv tsev txheej. Txij li thaum qhov kub ntawm qhov kub ntawm qhov cub tawg qhov chaw vault yog siab heev, tshaj 1400, lub siab alumina cib siv nyob rau hauv cov txheej txheem ua hauj lwm yog tsawg creep siab alumina cib. Silica cib, mullite cib, sillimanite, andalusite cib kuj siv tau rau hauv cheeb tsam no. ;

2. phab ntsa loj

Lub phab ntsa loj ntawm lub qhov cub kub kub yog hais txog cov phab ntsa ib puag ncig ntawm lub qhov cub kub kub lub qhov cub, nrog rau cov txheej txheem ua haujlwm ntawm cov cib, cov txheej filling thiab txheej rwb thaiv tsev. Cov txheej ua haujlwm cib siv cov pob zeb refractory sib txawv raws li qhov sib txawv ntawm qhov kub thiab txias. High alumina bricks yog siv nyob rau hauv nruab nrab thiab qis.

3. Regenerator

Lub regenerator yog ib qhov chaw uas muaj cov checker cib. Nws lub luag haujlwm tseem ceeb yog siv cov khoom siv hluav taws xob sab hauv los pauv cov cua sov nrog cov pa hluav taws kub kub thiab cua combustion. Hauv qhov no, qis creep siab alumina bricks yog siv, feem ntau nyob rau hauv nruab nrab txoj hauj lwm.

4. Combustion chamber

Lub combustion chamber yog qhov chaw uas muaj roj hlawv. Kev teeb tsa ntawm qhov chaw combustion chamber muaj kev sib raug zoo nrog lub tshuab hluav taws xob hom thiab cov qauv ntawm lub qhov cub kub kub. High alumina bricks feem ntau yog siv nyob rau hauv cheeb tsam no. Tsawg creep siab alumina cib yog siv nyob rau hauv qhov kub thiab txias, thiab zoo tib yam siab alumina cib yuav siv tau nyob rau hauv nruab nrab thiab tsawg kub.
