Nzvimbo dzeMashandisirwo Uye Zvinodiwa Zvepamusoro Alumina Zvidhinha Mune Anopisa Blast Stoves

Blast choto chekugadzira ironmaking inopisa blast chitofu chinhu chakakosha chepakati mukuita ironmaking.Zvidhinha zvakakwirira zvealuminium, sechigadzirwa chekutanga chezvinhu zvinoramba, zvinoshandiswa zvakanyanya muzvitofu zvinopisa.Nekuda kwekusiyana kukuru kwekushisa pakati pekumusoro nepasi kwechitofu chinopisa, zvinhu zvinoramba zvinoshandiswa muchikamu chimwe nechimwe zvinosiyana zvakanyanya.Nzvimbo huru dzinoshandiswa zvidhinha zvakakwirira zvinosanganisira hot blast furnace vault nzvimbo, madziro mahombe, regenerators, makamuri ekupisa, nezvimwewo sezvinotevera:

1. Dome

Iyo vault ndiyo nzvimbo inobatanidza kamuri yekupisa uye regenerator, kusanganisira dhizaini yekushanda yezvidhinha, dhizaini yekuzadza uye yekudzivirira.Sezvo tembiricha munzvimbo inopisa yevira yevira yakakwira zvakanyanya, inopfuura 1400, iyo yakakwirira alumina zvidhinha inoshandiswa muchikamu chekushanda ishoma inokambaira yakakwira alumina zvidhinha.Zvidhinha zvesilika, mullite zvidhinha, sillimanite, andalusite zvidhinha zvinogona kushandiswawo munzvimbo ino.;

2. Rusvingo rukuru

Rusvingo rwakakura rwechitofu chinopisa (hot blast stove) rinoreva chikamu chemadziro chakapoteredzwa chemuviri wekupisa kuputika kwechitofu, kusanganisira dhizaini yekushanda yezvidhinha, dhiri rekuzadza uye jira rekudzivirira.Iyo inoshanda layer zvidhinha inoshandisa zvakasiyana refractory zvidhinha zvinoenderana nekupisa kwakasiyana kumusoro uye pasi.High alumina zvidhinha inonyanya kushandiswa pakati uye pasi zvikamu.

3. Regenerator

Regenerator inzvimbo yakazadzwa necheki zvidhinha.Basa rayo guru nderokushandisa mukati mecheki zvidhinha kuchinjanisa kupisa nepamusoro-tembiricha flue gasi uye mhepo inopisa.Muchikamu ichi, yakaderera creep yakakwirira alumina zvidhinha anoshandiswa, kunyanya munzvimbo yepakati.

4. Kamuri yekupisa

The combustion chamber ndiyo nzvimbo inopisirwa gasi.Kugadzika kwenzvimbo yekamuri yekupisa kune hukama hukuru nemhando yevira uye chimiro chemoto unopisa unopisa.Zvidhinha zvepamusoro zvealuminium zvinonyanya kushandiswa munzvimbo iyi.Zvidhinha zvakaderera zvinokambaira zvakakwirira zvealuminium zvinoshandiswa munzvimbo dzekupisa, uye zvidhinha zvakakwirira zvealuminium zvinogona kushandiswa munzvimbo dzepakati nepakati.
