Kugirango usobanukirwe nuburyo bwo kubara ubucucike bwa retractory castable, umwobo wumwuka ni uwuhe?
1. Hariho ubwoko butatu bwa pore:
1. Uruhande rumwe rufunze urundi ruhande rushyikirizwa hanze, rwitwa gufungura pore.
2. Pore ifunze ifunze muri sample kandi ntabwo ihujwe nisi yo hanze.
3. Binyuze mu mwobo byitwa binyuze mu mwobo.
Igiteranyo cyuzuye, aricyo kintu cyukuri, bivuga ijanisha ryubunini bwuzuye bwa pore mubunini bwikitegererezo;Muri rusange, umwobo unyuze uhujwe nu mwobo ufunguye, kandi umwobo ufunze ni muto kandi bigoye gupima mu buryo butaziguye.Kubwibyo, ububobere bugaragazwa no gufungura ibintu, ni ukuvuga ikigaragara.Ikigaragara kigaragara bivuga ijanisha ryubunini bwuzuye bwa pore zifunguye murugero kugeza mubunini bwikitegererezo.
Ubucucike bwinshi bwerekeza ku kigereranyo cy’ubunini bwakorewe urugero rwumye nubunini bwacyo bwose, ni ukuvuga igipimo cyumubyimba wimyanya yumubiri wuzuye nubunini bwacyo, bigaragarira muri Kg / m3 cyangwa g / cm3.Ikigaragara kigaragara nubucucike bwinshi nimwe mubishingirwaho mugucunga ubwinshi bwimyanda ikorwa mubwubatsi.Ibipimo bibiri byerekana bishobora gupimwa hamwe nicyitegererezo kimwe.Ibikurikira nubucucike bwinshi kandi bigaragara ko ari ibintu bisanzwe bikoreshwa byangiritse.
2. Ibikurikira nubucucike bwinshi kandi bigaragara ko ari ibintu bisanzwe bikoreshwa byangiritse.
CA-50 sima ndende alumina ishobora guterwa, 2,3-2,6g / cm3, 17-20
CA-50 ibumba rya sima ibumba, 2.2-2.35g / cm3, 18-22
Ibumba rihujwe na alumina ndende, 2.25-2.45g / cm3, 16-21
Isima yo hasi ya aluminiyumu ishobora guterwa, 2,4-2.7g / cm3, 10-16
Ultra hasi ya sima hejuru ya alumina ishobora guterwa, 2,3-2,6g / cm3, 10-16
CA-70 sima corundum ishobora guterwa, 2.7-3.0g / cm3, 12-16
Amazi y'ibirahuri by'ibumba, 2.10-2.35g / cm3, 15-19
Fosifatike ya aluminiyumu ishobora guterwa, 2,3-2.7g / cm3, 17-20
Aluminium fosifate ya aluminiyumu ishobora guterwa, 2,3-2.6g / cm3, 16-20
3. Ubucucike bwa sima ntoya ishobora gutangizwa muri make hepfo
Isima nke ya sima ifata calcium aluminate sima nka binder, hamwe na castable ifite CaO iri munsi ya 2,5% mubisanzwe byitwa cement castable.Bitandukanye na gakondo gakondo, sima nkeya zateguwe mugusimbuza ibyinshi cyangwa byose bya sima ya alumina ya sima hamwe nifu ya superfine (ingano yubunini buri munsi ya microne 10) hamwe na agglomeration ihuza hamwe nibintu bimwe cyangwa bisa nibigize ibikoresho byingenzi, bigahindura ubunini bwibice gukwirakwiza, ifu ya micro, imiterere yibice nibindi bintu, no kongeramo umubare muto wo gutatanya (kugabanya amazi), urugero ruto rwa retarder hamwe nibindi byongeweho.
Ubucucike bwibumba rito rya sima ryangirika ni 2.26g / cm ³ hafi.
Ubucucike bwa alumina ndende ya sima yo kwangirika ni 2.3 ~ 2.6g / cm ³ hafi.
Corundum nkeya ya sima yangiritse ishobora guterwa n'ubucucike bwa 2,65 ~ 2.9g / cm ³ hafi.
