Dab tsi yog txoj kev kho rau kev tawg ntawm lub sim hluav taws xob rauv

1. Kho txoj kev rau cov kab nrib pleb los yog kev puas tsuaj ntawm qhov sib koom ntawm cov khoom siv refractory thiab cov phab ntsa rauv:

Cov ntaub ntawv tsis meej refractory tuaj yeem siv los thawb thiab kho, thiab thaum kho ntau yam loj, nws yuav tsum tau qhuav thiab siv.

2. Cov txheej txheem ntawm kev kho cov phab ntsa tawg ntawm lub cub tawg:

Tus txheej txheem ntawm kev kho cov phab ntsa sab hauv puas los yog me me yaig ntawm qhov kev sim hluav taws xob rauv yog tshem tawm cov slag thiab cov hlau seem, thiab tom qab ntawd siv cov iav dej. Tom qab ntawd siv cov khoom sib xyaw refractory ntxiv nrog 5% -6% dej iav rau thaj thiab kho cov khoom tsis zoo refractory. Thaum lub corrosion ntau ntawm phab ntsa ntawm lub tubular hluav taws xob rauv yog me ntsis loj, nws yog kho.

3. Kho txoj kev ntawm lub cub tawg hauv qab kev puas tsuaj:

Kev kho ntawm lub cub tawg hauv qab ntawm qhov kev sim hluav taws xob rauv tuaj yeem kho tau los ntawm kev ntxiv tib yam ntawm boric acid raws li lub cub tawg tshiab thiab sib tov cov khoom siv hluav taws xob sim hluav taws xob refractories sib npaug.
