Anthracite ci nyob rau hauv qhov chaw kiln thiab carbon blocks ua nrog cov ntaub ntawv me me uas yog cov khoom lag luam me me hauv cov pob txha mos me me hauv cov khoom siv pob zeb thaum lub sijhawm hnov. Tom qab cov pob txha lov thiab hlau infiltration, cov kab nrib pleb maj mam nthuav thiab ua ib qho molten hlau infiltration txheej. Txhawm rau tshem tawm cov cawv ntawm cov pob txha tawv ntawm cov khoom siv roj hmab (micropores tsis zoo) tau hloov kho cov pa roj carbon monoxide (micrroses Tus yuam sij rau ncua kev pabcuam lub neej ntawm cov txheej txheem yog kom siv lub zog tiv thaiv (graphite carbon bolas) ntawm kev ua haujlwm ntawm cov pa carbon block, yog li ntawd cov pa roj carbonRefractor Cibyog tsis muaj corroded.
Yuav ua li cas xaiv cov khoom ntawm cov kev sib tw sib xyaw ua ke hauv kev sim siab?Kev xaiv ntawm cov khoom ntawm cov hlau lub qhov ncauj ua ke hlau lub qhov ncauj ua ke yog tam sim no feem ntau tsim nrog cov xim av colundum cib lossis corundum-mullite cib. Lub peev xwm ntawm ob cov ntaub ntawv los tawm tsam yaig los ntawm molten hlau tsis zoo tagnrho, thiab cov hlau qhov ncauj tsis ruaj khov hauv kev tsim khoom. Raws li kev xyaum ntau lawm ntawm Anshan Hlau thiab Hlau yog 2580m3 thiab 1000m3 cov pa hluav taws xob tau siv rau lub tapole, qhov tob tob yog qhov ruaj khov thiab tswj tau yooj yim. Yog li ntawd, nws yog qhov tsim nyog los xaiv aluminium composite cib.
Kev xaiv ntawm cov ntaub ntawv rau tuyere composite cib
Tuyere muaj cov cib nyob niaj hnub no tsim nrog kev sib xyaw nrog cov xim av Corundum Refractory lossis Corundum-Mullite cib. Txij li thaum lub tuye sib xyaw ua thwv cib tau sib txawv hauv qhov cub hluav taws xob nrog cov khoom siv refractory nrog cov cua txias kom sai thiab cua sov thiab ua kom tawg. Raws li cov kev paub txawv teb chaws thiab kev ua ntau lawm ntawm Anshan Hlau thiab Hlau's No. 10 Lub tshuab pa hluav taws xob ua kom zoo dua. Tom qab cov cua sov ua kom tiav cov pa roj carbon burts-ceramic khob caj dab
(1) Qhov ntsuas kub tau ntawm cov cub rhing txheej tau hloov pauv tau ntau, thiab qhov ntsuas kub thiab qhov ntsuas kub thiab huab cua sov tau nce ntxiv. Ib nrab ib xyoos tom qab lub cub tawg tau qhib, qhov kub ntawm kev tiv tauj saum npoo ntawm ceramic khob txheej thiab cov carbon block yog ib txwm nyob hauv thaj tsam ntawm {1}} degree. Yog tias nws qis dua 750 degree (qhov sib txawv ntawm ntau tshaj 100 degree), nws qhia tau tias Phab Ntsa yog tuab.
(2) Lub cev kub ntawm cov hlau loj nce. Rau cov cua sov rauv ntawm tib lub ntim ntim, hauv qab cov ntsiab lus ntawm plaub hlau tsis sib txawv, cov degree sib txawv piv nrog cov tshuab hluav taws kub tsis muaj cov khob cij ceramic.
(3) nyob rau hauv cov kev txwv tsis tu ncua, thaum cov ntsiab lus silicon ntawm cov dej sib dhos thaum muaj cov tshuab cua daj cua dub Yog li ntawd, lub refractory cib cov ntsiab lus ntawm npua hlau tuaj yeem txo los ntawm 0.15% {9} {11 {kg / t.
(4) Tom qab lub cub tawg kom nce siab, qhov dej ntawm cov hlau uas ua kom zoo dua qub, uas txhim kho cov cua sov ntawm cov chaw ua cua sov.
(5) Thaum lub cua sov sov yog txuas ntxiv rau ({{
(6) Thaum cov hlau thawj zaug tawm tom qab lub sijhawm ntev ntawm cov hlau nres tsheb (ntau dua 8 teev
(7) Thaum lub cua sov sov yog siab ntev ntev (SI yog nyob rau hauv cov kab ke ntawm {1}}.}.}
