Ziziphi iingxaki ekufuneka ziqwalaselwe ngexesha lokunyibilikisa i-alloy smelting ?

1. Sukuthatha iisampulu kumphezulu wolwelo lobhedu kuvavanyo lokusebenza. I-alloys yobhedu ilula i-oxidize kwaye ifumane i-gas, kwaye i-slag kunye ne-gas content kwi-liquid surface iphezulu kakhulu kunokolweni oluphantsi lobhedu; ngoko ke, uvavanyo lokusebenza olwenziwa isampuli ulwelo ubhedu komhlaba ayichanekanga. Ukufumana iisampulu echanekileyo, emva kokuvuselela ngokupheleleyo ulwelo lobhedu, sebenzisa icephe lesampulu ukuze uqokelele isinyithi esinyibilikisiweyo ukusuka ezantsi kwi-crucible.

2. Ixesha lokunyibilikisa kufuneka lilawulwe . Ixesha ukusuka ekuqaleni kokunyibilika ukuya ekupheleni kokunyibilika libizwa ngokuba lixesha lokunyibilika. Ubude bexesha lokunyibilika abuchaphazeli kuphela ukuveliswa, kodwa ngokucacileyo kuchaphazela umgangatho wamacandelo atyhidiweyo. Ukunyuka kwexesha lokunyibilika kuya kwandisa isantya sokutshisa i-alloy kunye nokwandisa ithuba lokuphefumla. Ngoko ke, umsebenzi wokunyibilika kufuneka ugqitywe ngexesha elifutshane. Xa kuvunyelwe, zama ukunyusa ukushisa kwangaphambili kwentlawulo, ukusebenza kufuneka kuhlanganiswe, kwaye isenzo kufuneka sikhawuleze.

3. Intonga yokuvuselela esetyenziselwa ukunyibilikisa kufuneka ibe yintonga yekhabhoni. Ukuba ezinye izinto ezishukumisayo ezifana neentsimbi zentsimbi zisetyenzisiwe, iintsimbi zetsimbi ziya kunyibilika ngexesha lokuvuselela, okuya kuchaphazela ukubunjwa kweekhemikhali ze-alloy. Ngelo xesha, ukuba ukushisa kwangaphambi kokushisa kwentonga yensimbi kwisithando somlilo kuphezulu okanye ixesha lokuvuselela lide, i-oxides kwintonga yentsimbi iya kungena kwi-alloy liquid kwaye ibe yinto engcolileyo; ukuba ukushisa kwe-preheating yentonga yentsimbi kuphantsi, i-alloy iya kuxutywa ngexesha lokuvuselela. Kufuneka ifakwe kwintonga yentsimbi, enokuthi ibonwe kwimveliso.

4. Ukusetyenziswa kwe-arhente yokugquma ngexesha lokunyibilikisa. Ukunyibilikisa i-alloys zethusi, inani le-ejenti yokugubungela ngokubanzi : 0.8% -1.2% yobunzima bentlawulo xa usebenzisa iglasi kunye ne-borax , kuba ubukhulu bomgca wokugubungela ngu-10-15mm; Xa usebenzisa i-charcoal, i-dosage yi-0.5% -.0.7% yobunzima bentlawulo. Ukugcina ubukhulu bomgca wokugubungela we-25-35mm, ukuchithwa kwe-arhente yokugubungela ngokuqhelekileyo kuqhutyelwa ngaphambi kokuthulula. Kwangethuba kakhulu kuya kwandisa i-oxidation kunye nokufunxa kwe-alloy yobhedu. Ukuba i-charcoal isetyenziswe njenge-ejenti yokugubungela kunye ne-slag blocking effect ilungile, i-ejenti yokugubungela ayinakuchithwa, ukuze iphinde idlale indima yokuthintela i-slag ngexesha lokuthulula, kwaye umphumo ufanelekile ngakumbi.
