3.Isakhiwo Esiyinhloko:
Ukumelana nokuqhekeka kokushisa, ukumelana nokugqoka okuphezulu, ukumelana nokugqwala okuhle, ubulukhuni obuhle obubomvu; Ukumelana nokugqwala okuhle endaweni eqinile ye-asidi; Ukumelana okuhle nokuqhekeka kokugqwala kwengcindezi ku-hydrogen sulfide (H2S) nasezindaweni ze-chloride; Ukumelana nokugqwala okuhle kwe-intergranular; Ukumelana okuphezulu nokugqwala nokugqwala kwemigodi; Ukushisela okuhle;
4.I-alloy 28 Izindawo Zokusebenza:
Ivamise ukusetshenziswa emithonjeni yezindaba elimazayo efana nemboni yamakhemikhali, futhi ingasetshenziswa ekucubunguleni amakhemikhali, izinto zokulawula ukungcoliswa komhlaba, amapayipi emithombo kawoyela negesi, ukucutshungulwa kabusha kukaphethiloli enuzi, izinsizakalo zokusebenza ngaphansi komhlaba emigodini ejulile yesibabule, kanye nokucutshungulwa kwamakhemikhali e-phosphoric acid emanzi, amanzi olwandle, i-hydrofluorinated chloride kanye nokukhiqizwa kwe-organic acid kanye nemishini yokukha.
5.Izimfuneko Zokucubungula:
Ukunemba okuphezulu komshini ngu-0.01mm, isiphetho esiphezulu singu-RA0.6um, futhi ukugxila kwazo zonke izindawo eziyindilinga zangaphandle kungaphakathi kuka-0.05mm.
6.Inqubo Yokukhiqiza:
I-Raw forging: i-sanicro28 iyinsimbi engagqwali engajwayelekile, ebizayo, futhi umumo omkhulu, ububanzi obungaphandle obungama-200MM, akukho mpahla yebha yalokhu kucaciswa, ukusetshenziswa kokubumba ukukhiqiza umbungu woboya, ngenxa yokuqina okuphezulu kwento, ofaneleka kakhulu ukubumba impahla yebha njengento engenalutho yokucubungula. Usayizi wenetha we-workpiece ngemva kokucutshungulwa buyi-200 ububanzi obungaphandle nobude obuyi-1028, kanti uboya obunjiwe obusetshenzisiwe buyi-diameter yangaphandle engu-210 nobude obuyi-1100.
Ubunzima bokucubungula:Ngenxa yokuthi impahla inokuqukethwe okuphezulu kwe-chromium futhi iqukethe ingxenye ye-molybdenum, okuholela ekuqineni okuphezulu kwe-workpiece, okuqukethwe kwe-nickel nakho kuphezulu, ukuqina kwezinto ezibonakalayo kuphezulu, ukucubungula kunzima, futhi kulula ukuvela ukuphuka kwe-chip nokunamathela kanye nezinkinga zokuzwakala. i-blade, exazulula inkinga yokucubungula ukusebenza kahle kanye nethuluzi lokunamathela, kanye nenkinga ye-resonance ye-workpiece kanye nethuluzi lokuguqula.Usebenzisa indlela ekhethekile yokuhlela, ukusetshenziswa kokuguquguquka kwe-cyclic ngesivinini se-workpiece kanye nesivinini sokuphakelayo, isisombululo sokugcina esiphelele senkinga ye-resonance.
Ubunzima bokupholisha:I-viscosity ye-workpiece inkulu, okuholela emfucumfucwini engathi sína yezinto zokunamathisela zesondo lokugaya, futhi akunakwenzeka ukugaya ngokujwayelekile. Okokugcina, uhlelo lokuqedela i-lathe lusetshenziselwa ukuqedela imfuneko yokuqeda indawo engu-RA0.6um.
