Yakakwira alumina inoumbwa nezvidhinha
Yakakwira alumina inoumbwa nezvidhinha
Zvigadzirwa zvechigadzirwa: kukwirira kwakasimba, kurwisa kwakasimba kweasidhi uye alkaline slag, tembiricha yakasimba simba remagetsi, simba rakakura kusakara kuramba, peeling kuramba, kupisa kupisa kusagadzikana.
chigadzirwa tsanangudzo
Yepamusoro-aruminiyamu inoumba chidhinha A sintered yepamusoro-aruminiyamu inoumbwa nezvidhinha inoratidzirwa neyakaomeswa mamiriro, ayo anoumbwa neanoshanda dura uye kupisa kupisa dura. Iyo inoumbwa nezvidhinha yakarongedzwa dhizaini inoumbwa neanoshanda dura uye kupisa kupisa dura, uye ine yakanaka yakanaka moto-isingadziviriri uye kupisa kupisa maitiro. Iyo yekushanda dura uye iyo yekudzivirira yekuisa dura yakasarudzika batched uye yakasanganiswa panguva yekugadzirira, uye ndokuzoumbwa nekupfura pamwechete. Iyo yekushanda nhurikidzwa yezvinhu zvidhinha ine yakasimba simba yekubatanidza pamwe neiyo kupisa kuputira dura. Iyo yekushanda dura ine yakanaka yepamusoro tembiricha kuramba, acid uye alkali kuramba, abrasion kuramba, yakakwira simba, yakanaka yekupisa yekuvhunduka kugadzikana, kwakanaka kupisa kuputira kuita uye kusimba kwekupisa kuputira dura. kumusoro. Iyo inoumbwa nezvidhinha inogona kusangana nehunyanzvi zvinodikanwa uye zvinoshandiswa zvinoshandiswa neiyo rotary kiln, inogona kuona simba kuchengetedza uye kudyiwa kwekushandisa, uye kurebesa hupenyu hwehupenyu hweiyo rotary kiln. Iyo yekugadzirira nzira ndeyesainzi uye inonzwisisika, yakapusa uye yakapusa kuitisa, uye yakakodzera kune yekupfura bhandi uye firita bhandi rehukuru-hukuru hwakatenderera huni. Uye zvakare, yakakwirira-alumina inoumbwa nezvidhinha zvigadzirwa zvinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana senge magetsi emagetsi, simbi, isina-simbi simbi, petrochemicals, girazi, simenti uye zvekuvakisa.
Tsananguro yeakakwira-aruminiyamu anoumba zvidhinha:
1. Zvimiro uye mashandisiro:
Iyo ine yakakwira Refractoriness, yakasimba ngura kuramba kuacid uye alkaline slag, uye yakakwira michina simba pakakwirira tembiricha, saka inoshandiswa zvakanyanya mu metallurgia indasitiri uye mamwe mavira. Inonyanya kushandiswa kumubati weanopisa emhando dzakasiyana dzemoto senge magetsi emoto chitofu, choto chemoto, moto unopisa zvitofu, makomba, madhiramu esimbi, ngoro dzesimbi, simenti kilns, girazi kilns, nezvimwe. Inoshandiswa zvakanyanya mukugadzira simbi, kugadzira simbi, makemikari , simende nemamwe maindasitiri.
2. Chigadzirwa zvigadzirwa: zvakajairwa, zvakajairika uye zvakasarudzika-zvakaumbwa, zvakasarudzika-zvakaumbwa uye zvakasarudzika-zvakaumbwa zvidhinha.
3. Zvidhinha zvinopikisa zvinhu zvinogadziriswa zvine chimiro uye saizi. Zvidhinha zvine mutsindo zvine kutsiga kwakanaka uye zvinokodzera kupisa mabota, akasiyana mabhaira linings, mafuruji, makamuri ehutsi, nezvimwewo. Kune marudzi mazhinji ezvigadzirwa zvemabhiridha anokanganisa, uye zvikamu zvikuru ivhu, dombo, jecha, ore, hupfu zvichingoenda zvakadaro. Zvidhinha zvinokanganisa zvinowanzo kuve zvakapatsanurwa kuita mhando mbiri, zvisina kugadzirwa zvinodzora uye zvakaumbwa zvinomiririra. Isina kugadziriswa inoratidzira zvinhu: inonzi zvakare inotakurika, iyo yakasanganiswa powdery granule inoumbwa nemhando dzakasiyana siyana kana zviyero uye imwechete kana kupfuura anosunga. Kana yakashandiswa, inosanganiswa neimwe kana zvimwe zvinwiwa uye yakavhenganiswa zvakaenzana. Dzidzisa kufamba kwakasimba. Yakaumbwa inogadziriswa zvinhu: zvinowanzo gadzirwa zvinokanganisa zvidhinha, chimiro chine mitemo yakajairwa, uye inogona zvakare kugadziriswa kwechinguva zvinoenderana nezvinodiwa pakuvaka nekucheka.
