Indlela evame kakhulu yokukhiqiza amabhola aphikisayo

Enqubweni yokukhiqiza amabhola aphikisayo, indlela ye-hydroforming ivame ukusetshenziswa. Okulandelayo yisingeniso sendlela yokwenza abezindaba kanye nezinye iziphakamiso zokukhetha imishini.

1. Indlela yokwenza umshini wokunyathelisa iyindlela yokwenza esetshenziswa kakhulu ekukhiqizeni amabhola aphikisayo. Indlela isebenzisa ukucindezela kwebhola kanye nensimbi yokudayela ukuze iminyanise into eyenziwe yebhola ephikisayo ibe yindilinga. Njengoba ukwakhiwa komshini okuvamile kubhekisela endleleni yokwenza into eyomile kancane enamanzi angu-4% kuya ku-9%, kubuye kubizwe ngokuthi ukubumba okomile. Izinto ezisetshenziswayo ezivame ukusetshenziswa kule ndlela zihlanganisa umshini wokunyathelisa wezitini ezishayisanayo, umshini wokucindezela i-lever, nomshini wokunyathelisa nge-hydraulic.

2. Inqubo yokwenza umshini wokunyathelisa empeleni iyinqubo lapho izinhlayiya zebhola zigcwelena futhi umoya ukhishwa ukuze wenze i-sphere eminyene. Ibhola le-refractory elakhiwe ngomshini linezinzuzo zokuminyana okuphezulu, amandla aphezulu, ukushwabana okuncane kanye nokuncipha, nokulawula kalula usayizi webhola eliphikisayo. Ngakho-ke, le ndlela idlala indima enkulu ekukhiqizeni amabhola e-refractory.

3. Ukuze uthole i-sphere eminyene ngesikhathi sokunyathelisa, ukucindezela okwanele kufanele kunikezwe i-pellet. Ukucindezela kufanele kube ngendlela yokuthi ingakwazi ukunqoba ukungqubuzana kwangaphakathi phakathi kwama-pellets, inqobe ukungqubuzana kwangaphandle phakathi kwe-pellet nodonga lwesikhunta, futhi inqobe ukusabalalisa kwengcindezi okubangelwa umswakama we-pellet, izinhlayiya kanye nokugcwalisa okungalingani ekubumbeni. 

Ubudlelwano bokulingana phakathi kokuthathu buncike ekuhlakazweni kwama-pellets, ukwakheka kwama-pellets, umswakama wama-pellets, ubukhulu kanye nokuma kwezinhlayiya, nokunye okunjalo. Nakuba kunamafomula amaningana etiyetha okubala ubudlelwano phakathi kwengcindezi nokuminyana kwe-sphere, njengokushintshwa kwezimbotshana eziyindilinga ne-logarithm yokucindezela, indlela yokuhlola ivamise ukusetshenziselwa ukunquma ingcindezi ngeyunithi ngayinye yendawo ye-sphere, kanye ukucindezela kunqunywa ngokufanele. Ukucindezela okuphelele okufanele umshini wezitini ube nakho.

Izidingo zomshini wokwenza ibhola wezinto zebhola kufanele zibe nohla lokuguquguquka okuthile ngaphandle komswakama, futhi kunezidingo ezithile zosayizi wezinhlayiyana. Isibonelo, kufanele kube nesilinganiso sosayizi wezinhlayiyana ezifanele, futhi ukuminyana kwenqwaba kufanele kube kukhulu ngangokunokwenzeka. Ngokuvamile, ubukhulu bezinhlayiyana ezibucayi bungu-3 kuya ku-5 mm, futhi okuqukethwe kwempushane engaphansi kuka-0. 088 mm kufanele kube ku-35% kuya ku-45%.

Amaphutha ajwayelekile kakhulu amabhola e-refractory akhiwe ngomshini ukugcwala kanye nokuminyana kwezingqimba. I-spallation i-lamellar crack eyakhelwe i-perpendicular isiqondiso se-pressurization eyakhiwe ngesikhathi sokucindezela. Umswakama owedlulele ebholeni, izinhlawulo ezeqile, isibopho esincane kakhulu kanye nokucindezela okukhulu kungaholela ekuchithekeni.

Ngakho-ke, le mingcele kufanele ilawulwe ekukhiqizeni. Isenzakalo sokuminyana kwesendlalelo, okungukuthi, ukuminyana kwamabhola aphikisayo ngemva kokubunjwa, kuyahlehliswa kuhlangothi lwe-pressurization. Ibhola le-refractory elicindezelwe ngokungaqondile elisuka phezulu livamise ukuminyene futhi lincane, futhi indiza efanayo evundlile i-medium-density futhi ayincane. Lokhu kungenxa yokungqubuzana phakathi kwezinhlayiya zebhola kanye nokungqubuzana phakathi kwebhola nodonga lokufa. Indlela yokunciphisa ukungqubuzana kwangaphandle ngokucindezela kabili emaceleni kanye nokugcoba izindonga ezine zesikhunta kunganciphisa lo mkhuba futhi kunciphise i-porosity ye-sphere.

Ukukhethwa kwemishini yokubumba kufanele kucatshangelwe ngokuphelele ngokuya ngezidingo zekhwalithi, usayizi kanye nenani lokukhiqiza lebhola eliphikisayo. Ngokuvamile, ibhola le-refractory yesithando sokushisa noma umkhiqizo onomumo olula, inani elikhulu kanye nezidingo zekhwalithi evamile zingakhethwa ngokucindezela ibhola le-lever ngekhono eliphezulu lokukhiqiza; ibhola eliphikisayo elinemfuneko yekhwalithi ephezulu lingakwazi ukusebenzisa ukungqubuzana nokucindezela okuzisholo okungengaphansi kuka-2000K•N. Umshini webhola lokucindezela.
