Kev ntsuas kom txuas lub neej hloov pauv

1. Hloov cov txheej txheem masonry thiab txhim kho cov txheej txheem txheej txheem:

1.1 Raws li qhov xwm txheej ib txwm ua, cov cib ntub yuav tsim cov dej noo, uas tsis ua rau lub cev qhuav dej tas li ntawm 400 ° C. Cov hloov masonry tau txais kev sib xyaw ntawm cov masonry qhuav thiab cov masonry ntub, uas yog, txheej txheej sab saud thiab qis dua ntawm thaj chaw tuyere thiab lub qhov cub rauv qhov ncauj yog ntub masonry, thiab tas yog cov masonry qhuav.

1.2 Cov masonry ntawm cov tuyere cib tau hloov pauv los ntawm ib kawg mus rau nruab nrab mus rau ob qho kawg kom tsis txhob muaj daim duab peb sab sib txuas thiab tshem tawm ntawm tuyere cov cib sib xyaw.

1.3 Cov thooj av thim rov qab rau sab saud thiab qis rauv taws lub qhov ncauj tau muab sib dhos los ntawm ib kawg mus rau ob qhov kawg los ntawm nruab nrab mus rau ob hnub kom yooj yim rau kev xauv ntawm ob sab thiab tiv thaiv ob lub cib los ntawm kev poob vim qhov tsis sib xws thiab tsis zoo. khoob.

1.4 Kev faib tawm ntawm cov pob zeb sib koom ua tiav, tsis sib xws, zoo ib yam sab hauv thiab sab nrauv, thiab nthuav cov pob qij txha yuav tsum ua tau raws li qhov xav tau ntawm 2-3 hli. Cov pob qij txha ntawm lub cev cib ntawm txhua ntu yuav tsum raug kaw. Lub cib ua tiav lub cev yuav tsum tsis pub dhau ib feem peb, thiab lub cev cib ua tiav yuav tsum tsis pub tsawg dua ob feem peb ntawm nws tus kheej.

1.5 mg muab tub lim yuav tsum tau rub thiab tawg ntawm txhais tes thaum poob los ntawm qhov siab ntawm ib ‘meter’. Lub tuab thiab khov kho ntawm cov muab tub lim yuav tsum yog yam zoo ib yam.

1.6 Tsis txhob siv cov khoom puas, cornered thiab ntub chrome-magnesium cib.

2. Tswj cov khoom txias kom tiv thaiv kev kub hnyiab

Qhov kev ntsuas pom tias thaum chrome-magnesia cib muaj cua sov tiv taus ntawm 850 ℃, nws yuav tawg 18 zaug, uas yuav ua rau lub hauv paus tawg puas. Yog li ntawd, nws yog qhov tsim nyog kom tsis txhob muaj qhov kub hloov pauv ntawm lub tshuab ua kom sov, txo qis thiab tshem tawm cov cua sov kev puas tsuaj rau lub qhov cub tawg. Hauv kev tsim khoom, lub ntsuas cua sov tau ruaj khov los ntawm kev tswj tus nqi txias.

3. Tsim nyog tswj cov ntsiab lus silicon ntawm cov tshuab hloov pauv kom txo cov tshuaj xeb

Qhov nruab nrab lossis tsis muaj zog alkaline slag tuaj yeem tiv thaiv lub qhov cub tawg. Olivine magnesia muaj qhov cuam tshuam loj heev. Nws tuaj yeem tsis tsuas yog yaj cov nplaim ntawm magnesia refractories, tab sis kuj tuaj yeem nkag mus rau sab hauv ntawm magnesia refractories kom yaj.

Qhov kub siab dua, qhov ntau dua qhov kev daws teeb meem ntawm MgO hauv kev hloov pauv slag, thiab kev tsim cov forsterite nrog qis qis qis dua hauv qab qhov ntsuas kub siab, uas txo qis kev ua haujlwm ntawm magnesia cib. Hlau oxide kuj tseem tuaj yeem ua rau periclase thiab chromite hais, ua rau cov khoom puas thiab puas rau magnesia cib sai. Cov ntsiab lus silicon ntawm cov hloov pauv slag tsawg dua 18%, uas yog alkaline, thiab cov ntsiab lus silicon ntawm lub tshuab hloov pauv ntau dua 28%, uas yog acidic. Cov ntsiab lus silicon hauv lub tshuab hloov pauv yog nruab nrab ntawm 19% thiab 24%, uas yog nruab nrab lossis tsis muaj zog alkaline, thiab tsis muaj kev xeb rau magnesia cib txheej. Nyuaj tswj cov ntsiab lus silicon ntawm cov khoom sib hloov thaum tsim khoom kom ruaj khov nws ntawm 19% thiab 24%.

4. Txhim kho cov neeg ua haujlwm tau zoo

Txhim kho qhov zoo thiab muaj peev xwm ntawm kev tsim hluav taws xob, ua haujlwm hloov pauv thiab tswj cov neeg ua haujlwm kom ntseeg tau tias lub tshuab ua kom sov zoo.

Txhim kho cov peev txheej teb thaum muaj xwm txheej ceev, tshawb fawb thiab nruj tswj hwm thiab tswj hwm.

5. Xaiv qhov tsim nyog ntawm huab cua siv zog thiab oxygen concentration

Hauv cov txheej txheem tsim khoom, qhov tsis sib xws ntawm lub cev rauv thiab lub kiv cua yog qhov tsis yooj yim sua. Nws raug txwv tsis pub siv lub kiv cua txhawm rau muab cua nkag rau lub tshuab ua kom lub cev me me kom tiv thaiv kev yaig thiab ua rau lub cev qhuav dej loj nyob rau thaj tsam tuyere. Kev ntsuas cov pa oxygen ntau ntxiv ntawm cov hloov pauv yuav tsum tsis txhob siab dua 27%, cov pa oxygen yuav tsum siab dua 27%, thiab cov hauv av cib yuav tsum tau ntxuav ntau dua.
