Izinyathelo zokuphepha zokushisela umbhoshongo wamandla omoya

Enqubweni yokukhiqiza umbhoshongo wamandla omoya, ukushisela kuyinqubo ebaluleke kakhulu. Ikhwalithi yokushisela ithinta ngqo ikhwalithi yokukhiqiza yombhoshongo. Ngakho-ke, kubalulekile ukuqonda izimbangela zokukhubazeka kokushisela kanye nezinyathelo ezahlukahlukene zokuvimbela.

1. Ukufakwa kwembobo yomoya kanye ne-slag
Ukumbozwa: Ukumbozwa kubhekisela emgodini owakhiwe lapho igesi echibini elincibilikisiwe ingaphumi ngaphambi kokuqina kwensimbi futhi ihlala ku-weld. Igesi layo lingamuncwa yichibi elincibilikisiwe lisuka ngaphandle, noma lingadalwa ukusabela enqubweni yokushisela insimbi.
(1) Izizathu eziyinhloko zemigodi yomoya: kukhona ukugqwala, ibala likawoyela, njll. ebusweni bensimbi eyisisekelo noma insimbi yokugcwalisa, futhi inani lemigodi yomoya lizokhula uma induku yokushisela kanye ne-flux kungomiswanga, ngoba ukugqwala, ibala likawoyela, kanye nomswakama osekumbozweni kanye ne-flux yenduku yokushisela kuyabola kube yigesi ekushiseni okuphezulu, okwandisa okuqukethwe yigesi ensimbini eshisa kakhulu. Amandla omugqa wokushisela mancane kakhulu, futhi ijubane lokupholisa lechibi elincibilikisiwe likhulu, okungavumeli ukuphuma kwegesi. Ukuntuleka koketshezi oluningi kwensimbi yokushisela kuzokwandisa ne-oxygen porosity.
(2) Ukulimala kwemigodi yokuphefumula: imigodi yokuphefumula inciphisa indawo ephumelelayo yengxenye yokuxhuma futhi ikhulule i-weld, ngaleyo ndlela inciphise amandla kanye nokuqina kwelunga futhi ibangele ukuvuza. Ukuvuleka kwemigodi nakho kuyisici esibangela ukugcwala kokucindezeleka. Ukuvuleka kwe-hydrogen nakho kungabangela ukuqhekeka kokubanda.

Izindlela zokuvimbela:

a. Susa ibala likawoyela, ukugqwala, amanzi kanye nokoma okuvela ocingweni lokushisela, emseleni osebenzayo kanye nasezindaweni eziseduze kwawo.
b. Izinduku zokushisela ze-alkaline kanye nama-fluxes kufanele asetshenziswe futhi omiswe kahle.
c. Ukuxhumeka kwe-DC okuphambene kanye nokushisela kwe-arc emfushane kufanele kusetshenziswe.
D. Fudumeza ngaphambi kokushisela ukuze wehlise ijubane lokupholisa.
E. Ukushisela kufanele kwenziwe ngezincazelo eziqinile.

I-Crackle
Izindlela zokuvimbela imifantu yekristalu:
a. Nciphisa okuqukethwe kwezinto eziyingozi njenge-sulfur ne-phosphorus, bese uhlanganisa ngezinto ezinokuqukethwe okuphansi kwekhabhoni.
b. Izakhi ezithile ze-alloy zengezwa ukunciphisa amakristalu ekholomu kanye nokuhlukaniswa. Isibonelo, i-aluminium nensimbi kungacwengisisa okusanhlamvu.
c. I-weld enokungena okungajulile kufanele isetshenziselwe ukuthuthukisa isimo sokushabalalisa ukushisa ukuze izinto eziphansi zokuncibilika zintante ebusweni be-weld futhi zingabi khona ku-weld.
d. Imininingwane yokushisela kufanele ikhethwe ngokufanele, futhi kufanele kusetshenziswe ukufudumala kwangaphambili kanye nokushisa ngemva kwalokho ukuze kuncishiswe izinga lokupholisa.
e. Sebenzisa ukulandelana okunengqondo kokuhlanganisa ukuze unciphise ukucindezeleka kokushisela.

Izindlela zokuvimbela ukuphinde kufudumale imifantu:
a. Naka umphumela wokuqinisa wezinto zensimbi kanye nomthelela wazo ekufudumaleni kabusha kwemifantu.
b. Fudumeza kusengaphambili noma usebenzise ukushisa kwangemva kokushisa ukulawula izinga lokupholisa.
c. Nciphisa ukucindezeleka okusele ukuze ugweme ukugxilisa ingqondo ekucindezelekeni.
d. Ngesikhathi sokushisa, gwema indawo yokushisa ebucayi lapho kuphinda kufudunyezwe khona imifantu noma unciphise isikhathi sokuhlala kule ndawo yokushisa.

Izindlela zokuvimbela imifantu ebandayo:
a. Induku yokushisela ye-alkaline yohlobo lwe-hydrogen ephansi kufanele isetshenziswe, yomiswe kahle, igcinwe ku-100-150 ℃, futhi isetshenziswe lapho ithathwa.
b. Izinga lokushisa lokushisa ngaphambi kokushisa kufanele lenyuswe, kufanele kuthathwe izinyathelo zangemva kokushisa, futhi izinga lokushisa lokushintshashintsha phakathi kokushisa akufanele libe ngaphansi kwezinga lokushisa lokushisa ngaphambi kokushisa. Incazelo efanele yokushisela kufanele ikhethwe ukuze kugwenywe izakhiwo ezibuthakathaka neziqinile kushisela.
c. Khetha ukulandelana okunengqondo kokushisela ukuze unciphise ukuguquguquka kokushisela kanye nokucindezeleka kokushisela.
d. Yenza ukwelashwa kokushisa kokususa i-hydrogen ngesikhathi ngemuva kokushisela
