Isitini esiphakeme se-arc jikelele se-aluminium

Isitini esiphakeme se-aluminium jikelele se-arc siyinto ephikisayo engathathi hlangothi, engamelana nokuguguleka kwe-slag ene-acid ne-alkaline slag. Ngoba iqukethe i-SiO2, ikhono layo lokumelana ne-alkaline slag libuthakathaka kunaleyo ye-acidic slag. Ngaphezu kwalokho, ukumelana kwe-slag kwemikhiqizo ephezulu ye-alumina nakho kuhlobene nokuqina kwemikhiqizo ku-slag. Ngokuvamile, ngemuva kokubumba okuphezulu kwengcindezi nokudubula okushisa okuphezulu, imikhiqizo ene-porosity ephansi inokumelana okuphezulu kwe-slag.

I-arc yesitini se-arc yendawo yonke iyisikwele, futhi omunye umkhawulo uyindawo. Kungakhathalekile ukuthi iwugqinsi kangakanani, izoguquguquka futhi ilawuleke kalula. Ngoba ayinayo shaft futhi inokuchezuka okuncane ngosayizi, nayo ingakhiwa ibe isiyingi. Ngakho-ke ibizwa ngokuthi i-arc yendawo yonke, lolu hlobo lwezitini lusetshenziswa kuladle. Isitini esiphakeme se-alumina isitini sokukhanyisa sisetshenziswa kakhulu njengolwelwesi lwangaphakathi ebhakedeni lensimbi. Kwakuvamise ukuba ikakhulu ubumba. Manje kancane kancane ithathelwa indawo yisitini esiphakeme se-alumina. Isitini esiphakeme se-alumina universal arc siyisiliksi se-aluminium esinokuqukethwe kwe-alumina okungaphezulu kwama-48%. Ikhwalithi ephikisayo. Kwakhiwa futhi kubalwa nge-bauxite noma ezinye izinto zokusetshenziswa ezinokuqukethwe okuphezulu kwe-alumina. Ukuqina okuphezulu kokushisa, ukuphindisela okungaphezulu kwe-1770 ℃. Ukumelana kwe-slag kungcono.

Isitini esiphikisayo se-arc sisetshenziswa kakhulu njengolwelwesi lweladi. Bekukade kuyibumba ikakhulukazi, kepha manje kancane kancane lithathelwa indawo izitini eziphakeme ze-alumina. Ngokwesimo sokusetshenziswa, sikholwa ukuthi isitini se-arc jikelele sinezinzuzo ezilandelayo:

1.Ukucindezela okuphezulu namandla ukumelana nomhuzuko ekamelweni lokushisa. Ukumelana okuhle kwamakhemikhali, ikakhulukazi i-slag ene-asidi. Izinga lokushisa eliphakeme lokushisa liphansi. Ukusebenza okuhle kakhulu kokulwa nokuhlubuka.

2. Amalunga agobayo angahamba ngokukhululeka futhi angaya emuva naphambili ukulungisa ukuzungeza lapho ubeka izitini, ngakho-ke kulula ukwakha izitini ezikhombayo, futhi igebe lezitini ngokuvamile lingafinyelela ku-1 mm. Ubukhulu besitina selining bancishisiwe, futhi nomthamo wesigubhu sensimbi uyakhuphuka ngokufanayo.

3. Amajoyini abheke phezulu wezitini ze-arc jikelele mancane, okungaphansi ngama-70% kunamalunga aqondile wezitini ezijwayelekile zokuphikisa, ezinciphisa ukusetshenziswa kodaka lokuphikisa futhi konga izindleko zokuthengiswayo. Usayizi ungenziwa ngezifiso kunoma ibuphi ubude.

3. Impilo yensizakalo ende, enezitini zobumba ezincanyana kakhulu ezinyuke ngo-210%.

4. Kusukela ekunciphiseni ukusetshenziswa kokwelashwa kweyunithi, kukhombisa nokuphakama kwe-arc ephezulu ene-aluminium jikelele. Futhi ukwehliswa kokusetshenziswa kweyunithi kungachaza ukwehliswa okuhambisanayo kokufakwa okungekho kwensimbi kwensimbi encibilikisiwe.

5. Ngemuva kokuphinda usebenzise, ​​hlola ukuthi ukumelana nokugqwala kwesigaba sezitini eziphakeme ze-alumina ku-slag nensimbi encibilikisiwe kungcono kunesitini sobumba esine-clinker eningi.

6. Izitini ezi-arc zomhlaba wonke ezingasetshenziswa zingasetshenziswa lapho kubekwa izitini ngenxa yokuzungeza nhlangothi zombili. Hambisa emuva naphambili ukuze ulungise ukuzungeza, ngakho-ke kulula ukwakha izitini ezikhombayo, futhi igebe lezitini ngokuvamile lingafinyelela ku-1 mm.

7. Amalunga amile ezitini ze-arc jikelele mancane, okungaphansi ngama-70% kunamalunga aqondile wezitini ezijwayelekile ezikhanyayo, ukuze umphumela wokuguguleka kongqimba wensimbi encibilikile unyuke uye phansi futhi ujule emajoyinini ezitini kulungisiwe.

8. Ngenxa yokwenziwa ngcono kwekhwalithi yezitini ezikhanyelayo, ubukhulu bezitini zolwelwesi bungancishiswa, nomthamo wesigubhu sensimbi uyakhuliswa ngokufanayo.

9. Ngenxa yempilo ende yokusebenza kanye nokubekwa ngezitini okulula, umsebenzi wokwakha imigqomo yensimbi ngemuva kwesithando uyehla futhi nezinga lokusetshenziswa kwemigqomo yensimbi liyakhuphuka.

Izinkomba zomzimba nezamakhemikhali ezitini zomhlaba wonke:
