(Sawirka) GW taxane jeexan leben la neefsan karo

Lebennada la dami karo waxa loo qaybin karaa lebenka hawo-mareenka ee corundum-spinel, lebenka hawo-mareenka ee corundum-chromium, lebennada kursiga hawo-mareenka-lafdhabarta iyo lebennada kursiga hawo corundum-chromium oxide lebennada hawo sida waafaqsan qalabkooda.

1 Nidaamka laf-dhabarka ee Corundum leben neefsanaya

Sababtoo ah iska caabbinta slag iyo iska caabbinta shoogga kulaylka ee hal-waji ee corundum castables maaha mid ku habboon, maaddada lafdhabarta waxay leedahay caabbinta nabaad-guurka slag wanaagsan. Sidaa darteed, lafdhabarta isku-dhafka ah ee nadiifka ah ee nadiifka ah ayaa lagu daraa kabka corundum si loo gaaro ujeedada hagaajinta waxqabadka corundum castable. Walxaha ceeriin inta badan waa corundum saxan u eg, iyo lebenka hawada ka bixi kara ee lagu shido heerkul sare oo leh binder waxay leeyihiin iska caabin shoog kulayl oo wanaagsan iyo iska caabin ah.

2 Nidaamka Corundum-Chromium Oxide Leben La Neefsan karo

Si loo sii wanaajiyo iska caabinta daxalka birta birta ee lebenka hawada ka bixi kara, qadar gaar ah oo ah micropowder oxide chromium ayaa lagu daraa halabuurka. Walxaha ceeriin ee ugu muhiimsan waa corundum saxan u eg, iyo chromium oxide ayaa lagu daraa corundum castable. Heerkulka sare, chromium oxide iyo aluminium oxide waxay sameeyaan xalal adag oo heerkul sarreeya, isla mar ahaantaana waxay sameeyaan xal adag oo qayb ah MgO · Cr2O3-MgO · Al2O3 oo leh qadar yar oo ah magnesium oxide. Viscosity of this xal adag waa mid aad u sarreeya, iyo daxalka iyo iska caabinta Fe2O3 ama slag ayaa si weyn loo wanaajiyey, si dhexgalka iyo daxalka ee slag birta si wax ku ool ah looga hortagi karaa heerkulka sare. Isla mar ahaantaana, qadar yar oo Cr2O3 ah ayaa sidoo kale joojin kara koritaanka xad-dhaafka ah ee Al2O3, hoos u dhigista diiqada crystal, iyo hagaajinta sifooyinka jirka ee walxaha. Si kastaba ha noqotee, haddii qadarka isku-darku uu aad u weyn yahay, korriinka miraha corundum ayaa si xad dhaaf ah loo joojin doonaa, iyo walbahaarka gudaha ayaa sidoo kale la dhalin doonaa, taas oo yareyneysa sifooyinka jireed ee walxaha. Intaa waxaa dheer, qiimaha Cr2O3 waa mid aad u sarreeya, ku darida wax badan waxay si weyn u kordhin doontaa kharashka, waxayna saameyn gaar ah ku yeelan doontaa deegaanka.

3 Nidaamka Corundum-spinel leben fadhiga lagu neefsado

Nidaamka corundum-spinel leben fadhiga lagu neefsan karo ayaa ah shayga ugu badan ee la isticmaalo, iyo alaabta ceeriin ee ugu weyn waa corundum. Faa’iidada ayaa ah in lafdhabarta ay leedahay iska caabin xoog leh oo ku saabsan asiidhyada iyo alkaliska, waana bar dhalaalaysa sare leh oo leh waxqabad wanaagsan. Spinel-ka aluminium-magnesium wuxuu leeyahay iska caabin xooggan oo ku saabsan slag alkaline, wuxuuna leeyahay saameyn xasilloon oo ku saabsan oksaydhyada birta. Marka ay la xiriirto magnetite heerkulka sare, waxay ka falcelin doontaa si ay u sameyso xal adag, iyo iska caabbinta heerkulka sare ee leben fadhiga neefta waa la hagaajin karaa; Isla mar ahaantaana, xalka adag ee MgO ama Al2O3 spinel wuxuu leeyahay iska caabin shoog kuleyl ah oo ka wanaagsan sababtoo ah farqiga u dhexeeya is-ballaarinta u dhexeeya macdanta.

4 Nidaamka Corundum-Chromium Oxide Block la Neefsan karo

Nidaamka corundum-chromium oxide leben fadhiga lagu neefsan karo ayaa la soo saaray iyadoo lagu salaynayo nidaamka corundum-spinel si loo wanaajiyo iska caabinta heerkulka sare ee leben kursiga la neefsan karo. Waxyaabaha ugu muhiimsan ee ceeriin waa corundum tabular, iyo qadar yar oo ah budada chromium oxide ee warshadaha ayaa lagu daray. Faa’iidada ayaa ah in iyada oo lagu saleynayo hagaajinta waxqabadka lebenka by spinel, xalka adag ee ay sameeyeen Al2O3-Cr2O3 ayaa si weyn u kordhay iska caabinta daxalka ee birta oxide slag. Ku darista in ka yar Cr2O3 waxay joojin kartaa korriinka xad-dhaafka ah ee kiristaalo alumina, taasoo hoos u dhigaysa kiristaalo gudaha ah. Cadaadiska, wanaaji caabbinta shoogga kulaylka, caabbinta nabaadguurka iyo caabbinta nabaad-guurka ee lebenka fadhiga ee neefta.

Gebogebada hadalka

Si kasta oo ay u adag tahay xaaladaha isticmaalka goobta, iyada oo loo marayo waayo-aragnimadii hore ee isticmaalka iyo falanqaynta tijaabada goobta, waxa hubaal ah in aanu awoodi doono inaanu helno nooc leben neefsan kara oo buuxiya shuruudaha habka dhalaalidda goobta.
