Ndezvipi zvinhu zvinokanganisa zvinoshandiswa mualuminium indasitiri yamavira?

Refractory zvigadzirwa zvealuminium maovu maficha inowanzo kuveza zvidhina uye zvinokandwa, asi kusarudzwa kunosiyana zvakanyanya zvichienderana nezvikamu zvakasiyana. Refractories yealuminium maovu maficha anofanirwa kuve neakakwira simba rekusimudza, diki pore dhayamita, yakaderera zvemukati zveSiO2, Na2O, uye K2O. Iyo yekunamira yevira inofanirwa zvakare kunge iine yakanaka sintering mashandiro pane tembiricha ye800 ° C. Mupepeti weKerui Refractories akarongedza zvakajairika zvinhu zvekuratidzira zvealuminium maovu mafekitori kune ako mareferenzi chete.

Iyo yekupisa yekuputira dura yealumumina rotary kiln yakafukidzwa neyakagadzika wefreakist fiber yakanzwika pane yehovhoni ganda, uye ndokuzovakwa ne diatomaceous ivhu, inoyerera bead zvidhinha kana yakareruka ivhu zvidhinha, uye mamwe acho iye zvino atsiviwa neakajeka refractory castables. Iyo yekushandisa lining yenzvimbo yekupisa inovakwa nezvidhinha zvevhu, uye iyo yepamusoro-alumina zvidhinha kana phosphate-yakasungwa yakakwira-alumina zvidhinha zvinoshandiswa kune yakanyanya-tembiricha yekuverenga nzvimbo.

Parizvino, maficha asina kugadzirwa ave achishandiswa zvakanyanya muindasitiri yealuminium, senge yakaderera-calcium aluminate-yakasanganiswa inogadziriswa inokanda munzvimbo yecalcination, uye simbi faibha yakasimbisa yekupfeka-inodzivirira mirau yemiromo yemiln, masiki emoto, uye miswe yemota.

Iyo furani yevira ndeyekuisa kupisa-kusagadzikana simbi anchor zvipikiri kana zvedongo anchor pane yevira ganda, wozotambanudza nhete ye20mm gobvu refractory fiber yakanzwika, uye pakupedzisira kudira 200-300 gobvu refractory castables.

Iyo yekushandira lining yeiyo reverberatory tira yealuminiumel yekunyungudutsa furna inosangana neyakaumbwa aluminium inowanzo kuvakwa neakakwira-alumina zvidhinha ine Al2O3 zvemukati zve80-85%; paunenge uchinyungudisa yakakwira-yakachena simbi aluminium, mullite zvidhinha kana corundum zvidhinha zvinoshandiswa. Pamukwidza wechoto, isa tsvina aruminiyamu uye nezvimwe zvakapusa uye zvakasakara zvikamu, uye shandisa silicon nitride kusanganisa nesilicon nitride zvidhinha. Inoyerera aluminium troughs uye aluminium zvitoro zvakanyanyisa kumedzwa neyakaumbwa nesimbi. Kazhinji, kuzvisunga-simbi kana nesilicon nitride yakasungwa nesilicon carbide zvidhinha zvinoshandiswa, uye zircon zvidhinha zvinoshandiswa zvakare se linings. Iyo yevira yekunamatira iyo isingabatane nesimbi yakanyungudutswa inowanzo shandisa zvidhinha zvevhu, ivhu rinodzora castables kana repurasitiki mapurasitiki.

Iyo yekutsvaira yevira lining zvinhu zvekunyungudutsa aluminium uye aluminium alloys inowanzo yakakwira-aluminium yakaoma ramming zvinhu, kana silicon carbide inowedzerwa kune iyo alumina yakaoma ramming zvinhu, iyo isingaite kune mvura inodonha.
