Ib puag ncig Magnesia-Alumina-Carbon Cib

Kev tiv thaiv ib puag ncig magnesia alumina carbon cib rau pob tawb yog cov khoom lag luam tshiab tsim los ntawm peb lub tuam txhab raws li qhov xav tau ntawm cov neeg siv. Lub hauv paus tseem ceeb ntawm kev txhim kho cov khoom lag luam yog kev siv phaj corundum, kev tiv thaiv ib puag ncig thiab kev txhim kho kub ci. Txoj hauv kev no, tsis muaj roj phom sij ntawm formaldehyde thiab phenol hauv cov txheej txheem kom qhuav ntawm cov khoom tom qab siv cov tshuaj txhuam hniav, uas txhim kho ib puag ncig, txo qhov porosity ntawm cov khoom, txhim kho lub zog, thiab txhim kho slag corrosion kuj. Hauv lwm lo lus, kev siv cov khoom lag luam zoo dua.

1, Khoom piav qhia:

Peb tsim ib puag ncig-phooj ywg magnesia-alumina-carbon cib, siv cov fused magnesia zoo, zoo fused corundum xuab zeb, zoo graphite ua cov khoom siv tseem ceeb. tshwj xeeb tshaj yog hloov cov ntaub ntawv pov tseg, siv cawv-raws li kev tiv thaiv ib puag ncig cov tshuaj, ua kom sov qhov ci, ua rau cov khoom tsis muaj tshuaj lom thiab tsis qab, cov khoom hauv cov txheej txheem ci tom qab ua masonry, txhim kho ib puag ncig zoo, ua tiav qhov xav tau ntawm ib puag ncig zoo. Nyob rau tib lub sijhawm, cov khoom lag luam tau zoo dua qub, lub zog tau zoo dua qub, thiab qhov porosity tau txo qis heev. yog li ntawd, slag corrosion tsis kam thiab tiv taus xeb ntawm cov khoom tau txhim kho zoo heev, thiab kev pab lub neej ntawm cov khoom yog ntev dua li ntawm cov khoom sib raug zoo nrog cov khoom qub.

3, Khoom paub:Raws li cov khoom ib txwm ua ntawm magnesia-alumina-carbon bricks, ob qhov kev txhim kho loj tau ua tiav.one yog hloov cov ntawv ib txwm tso rau hauv ib puag ncig tiv thaiv hom cawv-raws binder, qhov thib ob yog hloov cov tsoos ci kub los ntawm 200 ℃ 20 txog 300 ± ± 10, qhov kev txhim kho no muaj cov hauv qab no zoo dua li cov khoom lag luam ib txwm muaj. 1: nrog kev hloov pauv ntawm phau ntawv, cov khoom tau dhau los ua ib puag ncig tiv thaiv cov khoom lag luam uas yog qhov tsis muaj tshuaj lom thiab tsis muaj teeb meem. cov khoom tau txhim kho kev ua haujlwm ib puag ncig zoo heev, thiab cov neeg siv muaj kev tshuaj xyuas zoo ntawm nws. 2: nrog kev nce ntawm qhov kub thiab txias, qhov ntom ntom, porosity thiab lub zog ntawm cov khoom zoo dua li cov khoom lag luam ib txwm muaj, yog li txhim kho kev siv cov khoom lag luam .users txaus siab heev nrog ob qho kev txhim kho no.

4, Daim ntawv thov khoom:ladle, hluav taws xob cua sov, tsheb torpedo, hloov pauv, thiab lwm yam.

1) Cov khoom muaj zog tiv taus rau cov hlau yaj nkag mus. Thaum siv cov khoom lag luam, kev nthuav dav tshwm sim los ntawm spinel nkag mus rau cov tshuaj tiv thaiv ntawm alumina thiab magnesia tuaj yeem tsim cov txheej txheej ntom ntom ntom ntom ntom ntom, uas tiv thaiv cov hlau tsis zoo los ntawm kev nkag mus rau sab hauv ntawm cov cib los ntawm kev sib koom ua ke ntawm cov txheej cib, yog li txhim kho kev pabcuam lub neej

2) Zoo heev slag corrosion kuj. Ntxiv nrog rau graphite, spinel tsim nyob rau hauv tus txheej txheem ntawm kev siv tuaj yeem nqus FeO hauv slag los tsim cov tshuaj sib tov, thaum Al2O3 cuam tshuam nrog CaO hauv slag los tsim CaO-Al2O3 sib xyaw nrog cov ntsiab lus siab, uas thaiv qee qhov pores, txhim kho cov ntsiab lus yaj thiab nce viscosity, yog li ua tau zoo paub lub hom phiaj ntawm kev tiv thaiv kev nkag mus thiab slag corrosion.

3) Lub zog muaj zog siab, cov ntsiab lus graphite qis hauv cov khoom, feem ntau hauv 6% - 12%, yog li ntawd, cov ntsiab lus siab alumina ntawm alumina magnesia carbon cib muaj qhov ntom ntom ntom (≥ 3.05 g / cm3), qis porosity (≤ 3.5%), siab lub zog (≥ 60) MPa

5, Khoom ntim:Thermal shrinkable zaj duab xis ntim ntim, pov thawj dej noo, ruaj, yooj yim thauj thiab tiv thaiv cov khoom los ntawm kev puas tsuaj.
