Izindlela zokukhiqiza zei-alloy steel tube

Ipayipi lensimbi elakhiwe lingahlukaniswa libe yi-forging yamahhala, ecasulayo, i-extrusion, i-forging, i-forging evaliwe yokufa, ukucasula okuvaliwe.Ukuvala ukufa kokubumba nokucasula okuvaliwe ngenxa yokuthi akukho flash, ukusetshenziswa kwezinto ezibonakalayo kuphezulu.With inqubo noma izinqubo eziningana kungase kube forgings eziyinkimbinkimbi kokuqeda.Njengoba kungekho flash, indawo yamandla okubumba iyancipha, umthwalo odingekayo uyancipha.Qaphela, Nokho, ayikwazi ukuvinjelwa blank ngokuphelele, lokhu kufanele ngokuqinile ukulawula ivolumu blank, ukulawula isikhundla isihlobo of the forging die kanye nesilinganiso forging, imizamo ukunciphisa die ukuguga.I-Orbital ingahlukaniswa nge-forging, swaging swing, rolling forging, wedge rolling, ring rolling kanye ne-cross rolling nezinye izindlela.I-Orbital, i-swaging ne-rolling ring iphinde yasebenzisa ukubumba okunembayo.

Ukuze kuthuthukiswe izinqubo zokucutshungulwa ngaphambi kokusetshenziswa kwempahla, i-roll forging kanye ne-rolling ingasetshenziswa njengento ebanzi.Ingxubevange steel amashubhu nge rotary forging forging free efanayo kwakhiwa endaweni, it has inzuzo uma kuqhathaniswa nobukhulu forgings, ngokwakha amandla amancane ngaphansi kwezimo kungafinyelelwa kwakheka.Izindlela ezinjalo zibandakanya ukubumba ipayipi lensimbi, kufaka phakathi ukubumba kwamahhala, izinto zokwakha ukuze zinwebe zisuka eduze kwendawo yamahhala yesikhunta, kunzima ukuqinisekisa ukunemba, ukuze ukuqondisa kokuhamba kwe-forging kufa kanye nenqubo yokuguquguquka elawulwa yikhompyutha, bangasebenzisa amandla okubumba aphansi ukuze bathole isimo esiyinkimbinkimbi, imikhiqizo enembayo ephezulu.Isibonelo, ukukhiqizwa kwezinhlobonhlobo, usayizi omkhulu we-turbine blade forgings.Lapho izinga lokushisa lepayipi lensimbi lidlula ama-300-400℃(i-steel blue brittle zone), ifinyelela ku-700-800℃, ukumelana ne-deformation kuzoncishiswa kakhulu, i-deformation ingabuye ithuthukiswe kakhulu.Ipayipi lensimbi elakhelwe ngokwamazinga okushisa ahlukene esifundeni, ngaphandle kwenqubo yokubumba kanye nezidingo zekhwalithi, lingahlukaniswa libe yindawo ebandayo, efudumele, eshisayo yokubumba indawo yokushisa emithathu.Lesi sigaba sasinezinga lokushisa elingenamingcele eqinile, ngokuvamile, kukhona indawo yokushisa ye-recrystallization ebizwa ngokuthi i-forging, i-forging ngaphandle kokushisa ekamelweni lokushisa ibizwa ngokuthi i-forging ebandayo.

Emazingeni okushisa aphansi i-forging, i-forging dimensional ushintsho luncane.Ku-700 elandelayo℃ukubumba, ukwakheka kwe-oxide encane, futhi akukho decarburization yangaphezulu.Ngakho-ke, inqobo nje uma amandla ipayipi deformation in the uhla amandla ukubumba, abandayo forging lula ukuthola ukunemba okuhle ntathu kanye isiphetho surface.Vele ulawule izinga lokushisa nokupholisa okokugcoba, 700℃lokhu okulandelayo okufudumele kungathola nokunemba okuhle.Hot forging, ngenxa amandla deformation kanye deformation ukumelana mancane, bobunjwa eziyinkimbinkimbi kungenziwa forgings ezinkulu.Ukuze uthole ukunemba okuphezulu kwe-forgings, ekushiseni kwe-900-1000℃hot forging inqubo.Futhi, qaphela ukuthuthukisa indawo yokusebenza yokubumba.Forging die life (2-5 eziyinkulungwane forging, forging afudumele 1-2 izinkulungwane eziyishumi, izinkulungwane eziyishumi ezibandayo forging 2-5) forging lokushisa uhla uma kuqhathaniswa nezinye mfushane, kodwa inkululeko, izindleko eziphansi .

Steel pipe blank lapho deformation abandayo futhi umsebenzi ukuqina, ngakho kufa ukumelana imithwalo high, Ngakho-ke, kudinga ukusetshenziswa high-amandla forging die futhi ukuvimbela ukuguga futhi eziboshiwe usebenzisa kanzima lubricating ifilimu processing indlela.Ngaphezu kwalokho, ukuvimbela crack billet, annealing Lesisemkhatsini ukuqinisekisa ukuthi izidingo deformation lapho kudingeka.Ukuze kugcinwe ukuthambisa okuhle, okungenalutho kungase kube ukwelashwa kwe-phosphate.Lapho usebenza nge-bar eqhubekayo kanye nenduku yocingo, isigaba samanje asikwazi ukugcotshwa inqubo, sifunda ukuthi kungenzeka yini ukusebenzisa indlela yokugcoba i-phosphate.
