Ukuhlukaniswa kwezitini eziphefumulayo (3)

(Isithombe) GW uchungechunge slit uhlobo isitini esiphefumulayo

Izitini ezivumelekile zingahlukaniswa zibe izitini ze-corundum-spinel system ventilation, i-corundum-chromium oxide system izitini zokungenisa umoya, i-corundum-spinel system ventilation seat izitini kanye ne-corundum-chromium oxide uhlelo lwe-ventilation seat izitini ngokusho kwezinto zabo.

1 Isistimu ye-Corundum-spinel isitini esiphefumula

Ngenxa yokuthi ukumelana ne-slag kanye nokumelana nokushisa okushisayo kwe-single-phase corundum castables akufanelekile, impahla ye-spinel inokumelana okuhle kokuguguleka kwe-slag. Ngakho-ke, i-spinel fused fused high-purity yengezwe ku-corundum castable ukuze kuzuzwe inhloso yokuthuthukisa ukusebenza kwe-corundum castable. Izinto ezingavuthiwe ngokuyinhloko ziyi-corundum emise okwepuleti, futhi izitini ezikwazi ukungena emoyeni ezishiswe ekushiseni okuphezulu nge-binder zinokumelana nokushaqeka okuhle kokushisayo kanye nokumelana ne-slag.

2 Isitini Esiphefumulayo Sesistimu ye-Corundum-Chromium Oxide

Ukuze kuthuthukiswe ngokwengeziwe ukumelana nokugqwala kwe-steel slag yesitini esingena umoya, inani elithile le-chromium oxide micropowder lengezwa ekubunjweni. Impahla eluhlaza eyinhloko i-corundum emise okwepuleti, futhi i-chromium oxide yengezwa ku-corundum castable. Emazingeni okushisa aphezulu, i-chromium oxide ne-aluminium oxide zakha izixazululo eziqinile ezisezingeni eliphezulu, futhi ngesikhathi esifanayo zakha isisombululo esiqinile esiyingxenye MgO · Cr2O3-MgO · Al2O3 enenani elincane le-magnesium oxide. I-viscosity yalesi sixazululo esiqinile siphezulu kakhulu, futhi ukugqwala nokumelana ne-Fe2O3 noma i-slag kuthuthukiswa kakhulu, ukuze ukungena nokugqwala kwe-slag yensimbi kungavinjelwa ngokuphumelelayo emazingeni okushisa aphezulu. Ngesikhathi esifanayo, inani elincane le-Cr2O3 lingaphinda livimbele ukukhula ngokweqile kwe-Al2O3, linciphise ukucindezeleka ku-crystal, futhi lithuthukise izakhiwo ezibonakalayo zezinto ezibonakalayo. Kodwa-ke, uma inani lokwengeza likhulu kakhulu, ukukhula kwezinhlamvu ze-corundum kuzovinjelwa ngokweqile, futhi ukucindezeleka kwangaphakathi kuzophinde kukhiqizwe, ngaleyo ndlela kunciphise izakhiwo ezibonakalayo zezinto ezibonakalayo. Ngaphezu kwalokho, intengo ye-Cr2O3 iphakeme uma kuqhathaniswa, ukungeza kakhulu kuzonyusa kakhulu izindleko, futhi kuzoba nomthelela othile emvelweni.

3 Isitini sesihlalo esiphefumulayo seCorundum-spinel

Isitini sesihlalo esiphefumulayo se-corundum-spinel siyinto esetshenziswa kakhulu, futhi impahla eluhlaza eyinhloko yi-corundum. Inzuzo ukuthi i-spinel inokumelana okuqinile nama-acids nama-alkali, futhi iyinhlanganisela ephezulu yokuncibilika ngokusebenza kahle. I-aluminium-magnesium spinel inokumelana okuqinile ne-alkaline slag, futhi inomphumela ozinzile kuma-iron oxides. Uma ihlangana ne-magnetite emazingeni okushisa aphezulu, izosabela ukuze yenze isisombululo esiqinile, futhi ukumelana nokushisa okuphezulu kokushisa kwesitini sesihlalo sokuphefumula kungathuthukiswa; Ngesikhathi esifanayo, isixazululo esiqinile i-MgO noma i-Al2O3 spinel inokumelana nokushaqeka okungcono kokushisa ngenxa yomehluko we-coefficient yokwandisa phakathi kwamaminerali.

4 I-Corundum-Chromium Oxide System Blockable Breathable

I-corundum-chromium oxide system isitini sesihlalo sokuphefumula sikhiqizwa ngesisekelo sesistimu ye-corundum-spinel ukuze kuthuthukiswe ukumelana nokushisa okuphezulu kwesitini sesihlalo sokuphefumula. Impahla eluhlaza eyinhloko i-tabular corundum, futhi inani elincane le-industrial chromium oxide powder liyengezwa. Inzuzo yukuthi ngesisekelo sokuthuthukisa ukusebenza kwezitini nge-spinel, isisombululo esiqinile esakhiwe yi-Al2O3-Cr2O3 sinokunyuka okuphawulekayo kokumelana nokugqwala kwe-iron oxide slag. Ukwengeza i-Cr2O3 encane kungavimbela ukukhula okweqile kwamakristalu e-alumina, ngaleyo ndlela kwehlise amakristalu angaphakathi. Ukucindezeleka, ukuthuthukisa ukumelana nokushaqeka okushisayo, ukumelana nokuguguleka nokumelana nokuguguleka kwesitini sesihlalo esiphefumulayo.

Ukuphetha amazwi

Kungakhathaliseki ukuthi izimo zokusebenzisa endaweni zimbi kangakanani, ngokusebenzisa isipiliyoni sangaphambilini sokusetshenziswa kanye nokuhlaziywa kokuhlolwa kwesayithi, ngokuqinisekile sizokwazi ukuthola uhlobo lwesitini esiphefumulayo esihlangabezana nezidingo zenqubo yokuncibilikisa esizeni.
