Chrome Corundum Brick

1. Chrome corundum zvidhinha zvinodaidzwawo zvepamusoro kupfeka-chiraomi chromium corundum ichirova chiteshi zvidhinha. Icho chigadzirwa chepamusoro-soro icho kambani yedu yakasimudzira kumusika mumakore mashoma apfuura. Iyo yakagadziriswa kubva kune yakachena alumina Al2O3 uye chromium oxide Cr2O3 seyakanyanya mbishi zvigadzirwa. Inofananidzwa neiyo yakachena corundum zvidhinha, ine zvirinani zvivakwa, senge Refractoriness uye kupfavisa deformation pasi pemutoro. Kupisa, simba rinoshanduka, kupisa kwekukwira, kukwirira kwetembiricha uye kugadzikana kwehurosi.

2. Inonyanya kushandiswa kupumburidza simbi yekupisa choto siraidhi njanji uye kubaya mapuratifomu, zvidyiro, uye zvimwe zvakapfekedzwa zviri nyore zvikamu zvemafekitori mafesi. Chrome corundum zvidhinha imhando yepamusoro-giredhi refractory zvinhu, uye hupenyu hwayo hwebasa hunogona kusvika gumi kusvika kumwedzi gumi nesere mushure mevazhinji vanoshandisa mamiririri.

3. Kudzidzira kunoratidza kuti kusapfeka chromium corundum kukanda chiteshi zvidhinha zvinoshandiswa mukutepfenyura chiteshi chekupisa choto chekupisa-chikamu chikuru mabhajeti, kukwesana kukuru padanho reyuniti uye chakakwira kuburitsa, izvo zvisinga gone chete kuwedzera hupenyu hwebasa re kurova chiteshi, uye kudzikamisa kumisa. Nguva yeFurnace, kuwedzera kugadzirwa, kudzora kushandiswa kwekushandisa uye kugadzirisa mitengo, uye kudzikisira huwandu hwekukurumidza kutonhora uye kudziyisa nekuda kwekudzimiswa kwevira rekuchengetedza, kuitira kuti hupenyu hwese hwevira huvandudzwe, uye pachena mabhenefiti ehupfumi anogona yakawanikwa. 4. Kushandisa α-Al2O3 sechinhu chisina kugadzirwa, ichiwedzera yakafanira chromium oxide poda uye yakanaka chromium corundum clinker upfu, mushure mekuumba, sintering pakakwirira tembiricha. Iyo chromium oxide yezvinhu sintered chromium solid solid bricks inowanzo kudzika pane iyo yeakasanganiswa-yakakandwa chromium corundum zvidhinha. Inogona zvakare kuve yakagadzirirwa neiyo slurry yekukanda nzira. Iyo α-Al2O3 powder uye iyo chromium oxide poda yakasanganiswa zvakaenzana, uye iyo glue uye organic binder inowedzerwa kugadzira gobvu slurry. Panguva imwecheteyo, chikamu che chromium corundum clinker inowedzerwa, uye chidhinha chinoitwa neiyo grouting nzira. Moto zvakare. Inogona kushandiswa sechigadziko chegirazi yezvidhinha, chivharo chekuvhara girazi rinoyerera gomba uye kutsigirwa kwesimbi inopisa prereatment mudziyo, marara incinerator, marasha emvura slurry yakamanikidzwa gasi, nezvimwe.

5. Refractory zvigadzirwa zvine alumina zvemukati zvinopfuura 90% uye corundum seyakanyanya kristaro chikamu. Yakanyanya yakanyanya yakajairwa tembiricha inomanikidza simba (inosvika 340MPa). Yakakwira mutoro yakanyorovesa kutanga tembiricha (inopfuura 1700 ° C). Yakanaka kwazvo makemikari kugadzikana, yakasimba kuramba acidic kana alkaline slag, simbi uye girazi mvura. Thermal kuvhunduka kugadzikana kunoenderana nemamiriro ayo. Iko kurwisa kwekuora kwezvigadzirwa zvakawandisa zvakanaka, asi kupisa kwekushisa kwakashomeka kwakashata. Kune mhando mbiri dze sintered corundum zvidhinha uye fused corundum zvidhinha. Sintered alumina uye fused corundum inogona kushandiswa senge mbishi zvinhu, kana bauxite kinki ine yakakwira Al2O3 / SiO2 reshiyo inogona kusanganiswa nesintered alumina uye inogadzirwa nesintering nzira. Phosphoric acid kana mamwe emahara ekubatanidza anokwanisa zvakare kushandiswa kugadzira isina-kufuridzirwa corundum zvidhinha.

6. Inonyanya kushandiswa mukugadzira simbi inovhuvhuta huni uye blast furna inopisa blast mavira, kuchenesa machira kunze kwesimbi inogadzira mavira, inotsvedza mvura yekupisa, girazi rinonyungudusa mavira uye petrochemical maovu emagetsi. Zvidhinha zveCorundum zvinoshandiswa zvakanyanya mumubatanidzwa weakasiyana-siyana ekushisa-turu nemakiriniki emoto muma petrochemical uye mafotereza maindasitiri, sekukamura, kugadzirisa maficha, uye maindasitiri esimbi.
