High- chrome cib feem ntau yog siv rau hauv iav qhov cub vim lawv qhov tshwj xeeb corrosion kuj thiab siab - kub stability. Qhov tseem ceeb ntawm lawv daim ntawv thov suav nrog:
Zoo heev Corrosion Resistance:Siab -chrome cibmuaj cov feem ntau ntawm chromium oxide (Cr₂O₃), muab kev tiv thaiv zoo tshaj rau slag corrosion thiab, tshwj xeeb tshaj yog, cov tshuaj corrosion los ntawm molten iav.
Piv nrog rau cov tsoos magnesia- chrome cib lossis lwm yam khoom siv refractory, siab -chrome cib zoo dua tiv thaiv cov tshuaj lom neeg tsis zoo thiab hnav lub cev cuam tshuam nrog cov txheej txheem iav melting.
Ruaj khov siab -Kev Ua Haujlwm Kub: Cov iav melting kub tuaj yeem tshaj 1500℃.
Ua tsaug rau lawv cov qauv kev ruaj ntseg zoo ntawm qhov kub thiab txias, siab - chrome cib khaws lawv cov duab thiab cov khoom, tiv thaiv kev deformation lossis kev puas tsuaj thaum lub sijhawm ua haujlwm siab - kub.
Daim ntawv thov nyob rau hauv qhov tseem ceeb: Hauv cov iav qhov cub, lawv nquag siv nyob rau hauv qhov chaw tseem ceeb xws li caj pas, phab ntsa kawg, thiab kaum tsev thaiv ntawm qhov chaw them nyiaj.
Cov chaw no yog nyob rau hauv kev sib cuag ncaj qha nrog siab -kub molten iav los yog raug thermal stress, xav tau cov ntaub ntawv refractory nrog cov yam ntxwv tshwj xeeb.
Kev tiv thaiv rau Alkali Corrosion: Tshwj xeeb tshaj yog nyob rau hauv furnaces uas ua rau alkali- iav dawb ntawm qhov kub thiab txias, siab - chrome cib yog siv los tiv thaiv lub cub tawg los ntawm kev puas tsuaj los ntawm alkaline molten iav.
Piv rau zirconia-cov ntaub ntawv, siab- chrome cib muab tsib mus rau kaum npaug ntau dua rau alkali corrosion.
Extended Service Life: Cov cuab yeej hais saum toj no tso cai rau siab -chrome cib kom txuas ntxiv lub neej kev pab cuam ntawm cov iav rauv, txo kev txij nkawm thiab kev poob qis, thiab yog li txhim kho kev tsim khoom thiab kev lag luam rov qab.
Cov Kev Siv Tshwj Xeeb: Kev siv siab - chrome cib yog nce hauv cov dej qab zib- txiv qaub iav tank furnaces; Cov ntawv thov tau nthuav dav dhau ntawm caj pas kom suav nrog cov phab ntsa kawg thiab lwm thaj chaw tshwj xeeb, ua kom pom kev lag luam paub txog lawv qhov kev hloov pauv thiab kev ntseeg tau.
Daim ntawv thov ntawm siab -chrome cib hauv cov iav qhov cub ua piv txwv lawv cov kev ua haujlwm siab thiab ua haujlwm ntev nyob rau hauv kev ua haujlwm hnyav, ua rau lawv yog ib qho tseem ceeb ntawm cov khoom siv refractory kom ntseeg tau cov iav tas li thiab cov khoom zoo ib yam.
Daim ntawv thov ntawm High-Chromium Bricks
High-chromium bricks tau dav siv los ua cov ntaub ntawv hauv ob sab phlu rau cov pa roj carbon monoxide thiab ua haujlwm ua haujlwm -cov ntaub ntawv rau cov pa roj carbon monoxide- dej slurry gasifiers.
Keeb kwm, siab -chromium refractories feem ntau yog siv nyob rau hauv qhov cub rau tempered iav, nrog txwv tsis pub siv nyob rau hauv rwb thaiv tsev iav tank furnaces. Niaj hnub no, txawm li cas los xij, siab -chromium cib tau nce ua haujlwm hauv cov dej qab zib-lime iav tank furnaces.
Lawv daim ntawv thov tsis txwv rau tag nrho lossis ib feem ntawm caj pas; lawv kuj tau siv nyob rau hauv kawg phab ntsa thiab, rau ib tug tsawg npaum li cas, raws li ces kaum blocks ntawm pub inlets.
Vim lawv cov tshuaj muaj pes tsawg leeg, siab -chromium cib ua rau muaj kev pheej hmoo ntawm iav tawg; yog li ntawd, lawv feem ntau suav hais tias tsis sib haum nrog "ultra-dawb" iav. Txawm li cas los xij, siab - cov khoom siv chromium tam sim no tau ua tiav hauv cov khoom siv hluav taws xob uas tsim cov iav ntshiab.
Qhov kom muaj nuj nqis ntawm siab -chromium cov khoom siv hauv cov iav qhov cub yog nyob ntawm qhov tsim thiab kev ua kom txias ntawm lub caj pas, lub qhov cub hluav taws xob txhua hnub, thiab nws cov kev ua haujlwm.
Cov tuam txhab iav tuaj yeem siv siab -chromium cib los tsim kom tag nrho lub cub tawg thiab phab ntsa kawg.
Kev sib koom ua ke siab -chromium cib masonry rau hauv caj pas caj pas pab txuas ntxiv lub neej kev pab cuam ntawm lub cub tawg, vim tias cov khoom siv tiv thaiv rau feem ntau hom iav yog tsawg kawg ob npaug ntawm cov fused- nrum cib.
