Ukwakhiwa kwe-carbon steel flangeslaphoukuganga okubandayo is umgunyathiat lokushisa eliphansi, ubukhulu thei-flange ehlanganisiweizinguquko ezincane kakhulu. Niniukuqamba ngezansiI-700 ℃, isikali se-oxide esincane siyakhiwa futhi akukho kukhishwa kwekhabhoni okwenzeka phezulu. Ngakho-ke, inqobo nje uma i-deformation ingaba ngaphakathi kwebanga lamandla okwakhiwa, ukubumba okubandayo kulula ukuthola ukunemba okuhle kwe-dimensional kanye nokuqedwa kwendawo. Uma nje izinga lokushisa kanye nokupholisa okokugcoba kulawulwa kahle, ukunemba okuhle kungatholakala ekubumbeni okufudumele okufika ku-700℃.Ukufa okubandayo, i-extrusion ebandayo, isihloko esibandayo nokunye ukucubungula kwepulasitiki ngokuhlanganyela. Ukubumba okubandayo kuyinqubo yokubumba ngaphansi kwezinga lokushisa le-recrystallization lento, futhi ukubunjwa kwenziwa ngaphansi kwezinga lokushisa lokubuyisela. Ekukhiqizeni, iukuqambaokungenalutho okungashiswanga kubizwa nge-cold forging. Izinto zokwakha ezibandayo ngokuvamile ziyi-aluminium kanye namanye ama-alloys, ithusi namanye ama-alloys, insimbi ye-carbon ephansi, insimbi ye-carbon steel kanye nensimbi ephansi ye-alloy yesakhiwo enokumelana nokuguquguquka okuphansi kanye ne-plasticity enhle ekamelweni lokushisa. Ama-forging abandayo anekhwalithi engaphezulu, anembayo ephezulu futhi angangena esikhundleni sokusikwa okuthile. Ukubumba okubandayo kuqinisa insimbi futhi kwandisa amandla e-flange.
Ukuthuthukiswa kobuchwepheshe bokubumba obubandayo ikakhulukazi ukuthuthukisa imikhiqizo ephezulu ye-value-added, ukunciphisa izindleko zokukhiqiza, ngesikhathi esifanayo, futhi njalo ukusika, i-powder metallurgy, i-casting, i-hot forging, inqubo yokwenza i-sheet metal kanye neminye imikhakha yokungena noma buyisela, kungabuye kuhlanganiswe nalezi zinqubo ukwenza inqubo eyinhlanganisela.
Iukushisa okushisayo kwama-flangesyi: phakathiukuzenzela okushisayo, ama-flange amakhulungezimo eziyinkimbinkimbi zingakhiwa ngoba amandla okuguqula kanye nokumelana nokuguqulwa kuncane kakhulu. Ukuze uthole ama-flange anembayo anobukhulu obuphezulu, ukubumba okushisayo kuyatholakala ebangeni lokushisa elingu-900-1000℃. Ngaphezu kwalokho, ukunakekelwa kufanele kukhokhwe ekuthuthukiseni indawo yokusebenza ye-hot forging. Forging die life (hot forging 2-5 thousand, forging warming 10-20 thousand, cold forging 20-50 thousand) ifushane kunezinye izindawo zokushisa zesifunda, kodwa inezinga elikhulu lenkululeko, izindleko eziphansi. Inhloso ye-flange ye-flange eshisayo iwukuba ukunciphisa ukumelana nokuguquguquka kwensimbi, ukuze kuncishiswe ukuguqulwa kwezinto ezimbi okudingekayo kwengcindezi yokubumba, ukuze i-tonnage yemishini yokubumba inciphe kakhulu; Enkambweni yokushisa okushisayo, isakhiwo esiqinile se-ingot yensimbi siguqulwa sibe isakhiwo esisha esinezinhlamvu ezinhle ngokusebenzisa i-recrystallization, futhi ukukhubazeka kwesakhiwo kuyancishiswa futhi izakhiwo zemishini zensimbi ziyathuthukiswa.
