Izitena eziphezulu zealuminium

Isitena se-aluminium ephezulu ye-arc yinto engathathi hlangothi, enokuthintela ukhukuliseko lwe-slag ene-acid kunye ne-alkaline slag. Ngenxa yokuba iqulethe i-SiO2, amandla ayo okumelana ne-alkaline slag abuthathaka kunaleyo ye-acidic slag. Ukongeza, ukuxhathisa kwe-slag yeemveliso eziphezulu ze-alumina kukwanxulumene nokuzinza kweemveliso kwi-slag. Ngokubanzi, emva kokubumba koxinzelelo oluphezulu kunye nokudubula okuphezulu kobushushu, iimveliso ezineporosity esezantsi zinokuxhathisa okuphezulu.

I-arc yesitena se-arc jikelele iyisangqa, kwaye elinye icala yindawo yokuhombisa. Nokuba ungqindilili kangakanani, iya kuba bhetyebhetye kwaye ilawuleke. Kuba ayinashafti kwaye inokuphambuka kancinci kubungakanani, inokwakhiwa kwakhona kwisangqa. Ebizwa ngokuba yi-arc yendalo iphela, olu hlobo lwezitena lusetyenziswa kwiladle. I-arc ephezulu ye-alumina ephezulu yezitena ezisebenzisayo isetyenziswa njengombhobho wangaphakathi webhakethi yentsimbi. Ibikade iludongwe ikakhulu. Ngoku ngokuthe ngcembe indawo izitena eziphezulu zealumin. Izitena eziphezulu zealumum arc zizinto zealuminium ezinomxholo wealuminium ongaphezulu kwama-48%. Umgangatho okwalatha. Yenziwe kwaye yabalwa kwi-bauxite okanye ezinye izinto ezinomxholo ophezulu wealumumina. Uzinzo olushushu oluphezulu, ukuphindaphinda okungaphezulu kwe-1770 ℃. Ukuxhathisa kwe-slag kungcono.

Isitena esiphikisayo se-arc sisetyenziswa ikakhulu njengombala welad. Ibikade iludongwe, kodwa ngoku ngokuthe ngcembe ithathelwa indawo zizitena eziphezulu zealumum. Ngokwemeko yokusetyenziswa, sikholelwa ekubeni isitena se-arc kwindalo yonke sinezinto ezilandelayo:

1.Ukucinezelwa okuphezulu kwamandla kunye nokuxhathisa kwe-abrasion kubushushu begumbi. Ukuchasana kakuhle kwemichiza, ngakumbi i-slag ene-asidi. Iqondo lokunyuka okuphezulu lobushushu liphantsi. Ukusebenza okuhle ngokuchasene nokuhluba.

2. Amalungu agobayo anokuhamba ngokukhululekileyo kwaye angaya ngapha nangapha ukuze ahlengahlengise ukujikeleza xa kubekwa izitena, ke ngoko kufanelekile ukwakha izitena ezinokwakha, kwaye isikhewu sezitena sinokufikelela kwi-1 mm ngokubanzi. Ukutyeba kwesitena sombane kuncitshisiwe, kwaye nomthamo wegubu lensimbi uyonyuka ngokufanayo.

3. Amalungu athe nkqo ezitena ze-arc kwindalo iphela mancinci, angama-70% ngaphantsi kwamalungu athe tye kwizitena ezichanekileyo, nto leyo enciphisa ukusetyenziswa kodaka olunqabileyo kunye nokugcina iindleko zokusetyenziswa. Ubungakanani bungenziwa ngokobude nabuphi na ubude.

3. Inkonzo ende, izitena zodongwe ezinyinyithekileyo zonyuke nge-210%.

4. Ukususela ekunciphiseni ukusetyenziswa kwonyango, kubonisa ukuphakama kwe-aruminium ephezulu ye-arc. Kwaye ukuncitshiswa kokusetyenziswa kweyunithi kunokucacisa ukuncitshiswa okungqinelanayo kokufakwa okungekho kwesinyithi kwisinyithi esityhidiweyo.

5. Emva kokuphinda usebenzise, ​​jonga ukuba ukumelana necandelo lezitena zealumin ephezulu kwi-slag kunye nentsimbi etyhidiweyo kungcono kunaleyo yezitena zodongwe zininzi.

6. Izitena eziphikisayo zingasetyenziswa xa kubekwa izitena ngenxa yokujikeleza macala omabini. Hambisa ngapha nangapha ukuze uhlengahlengise ukujikeleza, ngoko ke kufanelekile ukwakha izitena ezikhanyelayo, kwaye isikhewu sezitena sinokufikelela kwi-1 mm.

7. Amalungu athe nkqo kwizitena ze-arc jikelele mancinci, engaphantsi ngama-70% kunamalungu athe tye ezitena ezichanekileyo, ukuze umphumo wokhukuliseko lomaleko wentsimbi otyhidiweyo usenyuka usiya ezantsi kwaye ungene nzulu kumalungu ezitena ilungisiwe.

8. Ngenxa yokuphuculwa komgangatho wezitena ezitsalayo, ukutyeba kwezitena kungancitshiswa, kwaye nomthamo wegubu lesinyithi uyonyuka ngokufanayo.

9. Ngenxa yobomi bexesha elide kunye nokubekwa kwezitena ngokufanelekileyo, umsebenzi wokwakha imigqomo yentsimbi emva kwesithando uyancitshiswa kwaye izinga lokusetyenziswa kwemigqomo yentsimbi liyenyuka.
