Xeetu jumtukaay yi ñuy jëfandikoo ngir four arc submergé (SAF) ñooy njëkka am yaram wu four bi, kaw four bi, busbar yu gàtt yi, sistemu seddal ndox, sistemu exhaust, sistemu dindi pënd, sistemu recuperation bu tàngoor bu baaxul, sistemu casing ak electrode tegkatu electrode yi, ubbikaayu robinet yi, sistem hydraulique yi, transformatëru four bi, ak yeneen jumtukaayi kuuraŋ.
Jëfandikoo bu njëkk ci four arc submergé
Four arc submergé four électrik la buy jëfandikoo procédure arc submergé ngir defar ay ferroalloy yu melni ferrochrome. Ñu xamee ko itam ni four arc électrique wala four résistance électrique, ñu ngi koy njëkka jëfandikoo ngir wàññi li ñuy fonde macceer premier, lu ci melni mineraal, agents réducteurs carboniques, ak flux. Dafa am reservoir bu four bu mëna tàkk, ak ñatti electrode yuñ suul ci biir slag biy seey.
Four à arc submergé ñooy jumtukaay yiñ gëna jëfandikoo ngir defar ay aleage ferro yu melni ferrosilicon, ferromanganese, ferrochrome, tungstène, ak aleage silicomanganese. Ferroalloys yooyu dañuy nekk macceer premier yu am solo ci usine yi, ñu am njariñ lu bari ci defar asiye, ci forage ak ci defar masin.
Defar ay macceer chimik yu bees:
Four à arc submergé dañu koy jëfandikoo itam ngir defar ay produit chimik yu melni carbure de calcium. Carbure de calcium matiere premiere bu am solo la ci liggéeyum chimik; Dañu koy jëfandikoo ngir defar gaz yu melni asetylene, ñu koy jëfandikoo ci yeneen mbir yu melni soudure ak dagg.
Fondement des métaux non ferrous:
Four à arc submergé mën nañu ko jëfandikoo itam ngir xeeñ metal yu amul fer, lu ci melni përëm ak aluminium, ci wàññi oxide metal yi ñu nekk metal yu sell jaaraleko ci reaction reduction.
Màndarga yi am ci four arc submergé
1) Benn ci njariñ yi gëna am solo ci liggéeyum fondeur arc submergé mooy mën na defar aleage ferrochrome yu baax te bariwul carbon.
Ni ñu koy defee mooy ñu am atmosphere buy wàññi bu baax ci biir four bi, loolu mooy tax oxide chromium bi mëna wàññeeku bu baax nekk chromium metalik. Bu bariwul karbon lu am solo la sooy defar asiye inox, ndax dafay jàppale macceer bi mu baña yàqu.
Four à arc submergé itam mën nañu jëfandikoo ay macceer yu bari yu ci melni mineraal chromite bu baax te mën nañu baña mëna jëfandikoo ci yeneen xeeti defar.
Yooyu tànneef ci macceer bu bees bi moo tax liggéey bi gëna xéewale te gëna mëna yàgg. Rax ci dolli, four bi mën na jëfandikoo matiere premiere yu bari, loolu mooy tax ñu mëna defar xeeti ferrochrome yu bari ngir mëna dëppoo ak bëgg-bëggu kiliyaan yi.
2) Processus smelting arc submergé dafay joxe energie bu baax.
Tàngoor wi ñuy génne ci liggéey bi dañu koy jëfandikoo bu baax, moo waral energie bi gëna néew buñu ko méngale ak yeneen xeeti defar ferrochrome. Energie bu baax bi taxul ñuy wàññi njëgu liggéey bi, waaye dafay tax itam liggéey bi gëna baax ci environmaa bi.
Sooy seet kàttanu liggéey bi, four arc submergé yi dañu leen di defar ngir ñu mëna jëfandikoo volume yu bari ci wen wuy seey. Loolu dafay tax ñu mëna wéy di liggéey, suko defee ñu mëna am ferrochrome bu bari ngir mëna jàppandi ak bëgg-bëggu liggéeyukaay yi ci asiye inox. Kàttan gu bari itam dafay tax liggéey bi mëna am njariñ ci wàllu koom, yombal koom-koomu escale bi ak wàññi njëg yi.
Defar ferrochrome jaaraleko ci four arc submergé amna njeexital yu am solo ci liggéeyum asiye inox. Ferrochrome bu baax biñ defaree ci anam yii dafay tax produit acier inox yi di wéy di baña yàqu, di yàgg te rafet.
Li muy mëna defar ferrochrome bu baax te bariwul carbon, boole ci neexaay bi ci tànneefi macceer bu bees, energie bu baax, ak kàttanu defar bu bari, moo tax defarkati asiye inox yi ñoo ko gëna bëgg. Ginaaw laaj bi ci asiye inox mingi wéy di yokk, liggéeyu wàññi smelting bi dina wéy di nekk cër bu am solo ci liggéeyum defar ferrochrome.
3) tàngoor -
Four à arc submergé dafay am tàngoor wu yéeg, loolu mooy tax élément metal yi ci biir mineraal bi mëna seey ba noppi tàqaloo bu baax.
4) Flexibilite ak mëna yamale:
Bëgg-bëggu fonder ngir mineraal yu bari mën nañu ko méngale ak ay parametre yu melni njaxasu charge ak tàngooru tàngoor.
5) Aar environmaa bi ak kaaraange:
Dañu wara saytu bu baax gaz yu ñuy bàyyi ci jawwu ji suñuy fonde ngir wàññi polusioŋ biy yàq environmaa bi. Rax ci dolli, seddal produit bi dafay baax te wóor.
Prosedur four arc submergé dafa am njariñ yu bari ci yeneen xeeti raffinage. Lii xeetu liggéey bu am njariñ la, mën na jëfandikoo macceer bu bari ci benn yoon, moo tax mën nañu ko jëfandikoo ci liggéey yu mag ci usine yi.
Rax ci dolli, four arc submergé bi gëna xéewale buñu ko méngale ak yeneen pexe yi. Jëfandikoo kuuraŋ ngir tàngal, doo soxla essence bu seer. Rax ci dolli, mën nañu jàpp produit yi bawoo ci raffinage bi, jëfandikoo leen ci yeneen mbir, loolu dina wàññi waste ak njëg yi.
