T38 yakakwirira alumina chidhinha (banga mhando)

T38, t39 yakakwirira alumina zvidhinha ndizvo zvinhu zvikuru zveakakwira alumina bauxite; sillimanite group zvicherwa (kusanganisira kyanite, andalusite, sillimanite, nezvimwewo); chakaita zvokugadzirwa mbishi zvinhu, zvakadai maindasitiri alumina, chakaita zvokugadzirwa mullite, magetsi Fused corundum uye zvichingodaro. China yepamusoro alumina banadium yakapfuma mune zviwanikwa uye yakanakisa mukugadzirwa. Nzvimbo dzekugadzira dzinonyanya kugoverwa muShanxi, Henan, Hebei, Guizhou, Shandong nedzimwe nzvimbo. Iyo yakakwira alumina bauxite inogadzirwa inonyanya musanganiswa webauxite (α-Al2O3 · H2O) uye kaolinite.

Yakakwirira alumina zvidhinha chinhu kwazvakarerekera refractory zvinhu pamwe alumina kugutsikana kwete asingasviki 60%. Iyo inoumbwa uye yakavezwa kubva kubhauxite kana zvimwe zvigadzirwa zvakasvibirira zvine yakakwirira alumina zvemukati. Yedu fekitori inogadzira yakakwira alumina zvidhinha neakanyanya kudziya kutsiga uye Refractoriness pamusoro pe1700 ℃. Kurwisa kwakanaka kwe slag kunonyanya kushandiswa kumubhedha wemoto unopisa, unopisa mafesi, emoto wedenga remba, kuputira mavira, reverberatory mavira, uye Rotary kilns. Zvigadzirwa zvikuru zvefekitori yedu zvakajairika zvidhinha zvepamusoro-alumina (kureva T-musoro zvidhinha) T-3 T38 T39 T19 T20 T23 T7 T52 T1, yakasarudzika-yakasarudzika-alumina zvidhinha, blast vhezheni refractory zvidhinha G2 G3 G4 G5 G6 GXNUMX kona yezvidhinha nezvimwe zvidhinha zvemhando yepamusoro zvinokanganisa.

1. Refractoriness: Iyo Refractoriness ye t38 uye t39 yakakwira alumina zvidhinha yakakwira kupfuura iyo yevhu zvidhinha uye semi-silika zvidhinha, inosvika 1750 ~ 1790 ℃, zvinova zviri zvemberi zvinokanganisa zvinhu.

2. Takura tembiricha inopfavisa: Nekuti yakakwirira aluminium zvigadzirwa zvine yakakwira Al2O3, isina kuchena, uye isina girazi fusible, mutoro unodzikamisa tembiricha wakakwirira kudarika zvidhinha zvevhu uye zvidhinha zvealumumina, asi nekuti makristasi emullite haaite chimiro chenetiweki pasi pemutoro haisati yakakwira seiya yezvidhinha zvesilica.

3. Slag kuramba: yakakwirira alumina zvidhinha zvine zvimwe Al2O3, iri padhuze nekusarerekera zvinhu zvinopesana, uye inogona kudzivisa kukukurwa kweacidic slag uye alkaline slag. Sezvo iine SiO2, kugona kurwisa alkaline slag kuri nani pane iyo acidic slag. Weaker. Iyo nzira yekugadzira yeakakwira alumina zvidhinha uye yakawanda-inonamira ivhu zvidhinha zvakafanana. Musiyano ndewekuti chikamu chekliniki muzvinhu zvakakwirira, izvo zvinogona kuve zvakakwirira se 90-95%. Iyo clinker inoda kurongedzwa uye kubviswa kuti ibvise simbi isati yapwanyika, uye tembiricha yekupfura Yakakwira, senge Ⅰ, Ⅱ yakakwira alumina zvidhinha zvinowanzo kuve 1500 ～ 1600 ℃ pavanodzingirwa muhuni wemugero. Kugadzira tsika muChina kwakaratidza kuti usati wapwanya, yakakwira-alumina clinker inosarudzika uye kusarudzwa, uye kuchengetwa mumatatu. Iko kushandiswa kwebauxite clinker uye yakasanganiswa yevhu yakanaka yekugedza nzira inogona kuvandudza chigadzirwa chigadzirwa. Inonyanya kushandiswa kuvaka mhepo inoputika, moto unopisa, uye magetsi emoto. , Blast furnace, reverberatory furnace, Rotary kiln lining, nezvimwewo.

Yepamusoro-alumina Refractory chidhinha, ndiko kuti, aruminiyamu silicate inoonekera zvinhu zvine alumina zvemukati zvinopfuura 48%. Iyo inoumbwa uye yakavezwa kubva kubhauxite kana zvimwe zvigadzirwa zvakasvibirira zvine yakakwirira alumina zvemukati. Yakakwira kudziya yakasimba, kudzvanywa pamusoro pe1770 ℃. Kurwisa kwe slag kuri nani.

Kazhinji yakakamurwa kuita zvikamu zvina.

Kirasi I: Al2O3 zvemukati ≥75%;

Kirasi Ⅱ: Al2O3 zvemukati 60% ~ 75%;

Kirasi Ⅲ: Al2O3 zvemukati zviri 48% ~ 60%;

Yakakosha kirasi: AL2O3 zvemukati ≥80%.

Inogona zvakare kuverengerwa zvinoenderana nemaminerari ayo, akaganhurwa muzvikamu zvishanu: yakaderera mullite (sillimanite), mullite, mullite-corundum, corundum-mullite uye corundum.
