3.Ipropati ePhambili:
Ukuchasana nokuqhekeka kobushushu, ukumelana nokunxiba okuphezulu, ukuxhathisa okuhle kokubola, ubulukhuni obuhle obubomvu; Ukuxhathisa okulungileyo kokutya kwindawo eqinileyo yeasidi; Ukuchasana kakuhle noxinzelelo lwe-corrosion cracking kwi-hydrogen sulfide (H2S) kunye neendawo ze-chloride; Ukuchasana kakuhle kwe-intergranular corrosion; Ukuxhathisa okuphezulu kwimingxuma kunye nokubola kwemingxuma; Weldability elungileyo;
4.I-Alloy 28 Iindawo zokuSebenza:
Ihlala isetyenziswa kumajelo eendaba ezonakalisayo ezifana neshishini lemichiza, kwaye ingasetyenziselwa ukusetyenzwa kweekhemikhali, izixhobo zokulawula ungcoliseko, imibhobho ye-oyile nerhasi, ukucocwa kwakhona kwamafutha enyukliya, iinkonzo zokusebenza ezingaphantsi komhlaba kwimithombo yegesi yesulfure enzulu, kunye nokusetyenzwa kweekhemikhali ze-asidi ye-phosphoric emanzi, amanzi olwandle, i-hydrofluorinated chloride kunye ne-organic acid yemveliso kunye nezixhobo zokuchola.
5.IiMfuno zokuSebenza:
Eyona nto iphezulu yokuchaneka komatshini yi-0.01mm, ukugqiba okuphezulu yi-RA0.6um, kunye nokugxila kwayo yonke imiphezulu esetyhula yangaphandle ingaphakathi kwe-0.05mm.
6. Inkqubo yoMatshini:
I-Raw forging: i-sanicro28 yinto engavumelekanga yensimbi engenasistim, ebiza, kwaye imilo enkulu, ubuninzi obungaphandle kwe-diameter yi-200MM, akukho zixhobo zebhari zale nkcazo, ukusetyenziswa kwe-forging ukuvelisa i-embryo yoboya, ngenxa yobunzima obuphezulu bezinto eziphathekayo, eyona nto ifanelekileyo yokwenza izinto zebha njenge-process blank. Ubungakanani bomnatha bomsebenzi emva kokucwangciswa bungama-200 ububanzi obungaphandle kunye nobude be-1028, kunye noboya obunjiweyo obusetyenzisiweyo yi-210 ububanzi obungaphandle kunye ne-1100 ubude.
Ukuqhubekekisa ubunzima:Ngenxa yokuba izinto zinomxholo ophezulu we-chromium kwaye ziqulethe inxalenye ye-molybdenum, okubangelwa ubunzima obuphezulu be-workpiece, umxholo we-nickel uphezulu, ubunzima bezinto eziphathekayo buphezulu, ukucubungula kunzima, kwaye kulula ukuvela ukuphulwa kwe-chip kunye nokunamathela kunye neengxaki ze-resonance. i-blade, eyisombulula ingxaki yokusebenza kakuhle kunye nesixhobo sokunamathela, kunye nengxaki ye-resonance ye-workpiece kunye nesixhobo sokuguqula.Ukusebenzisa indlela ekhethekileyo yokucwangcisa, ukusetyenziswa kweenguqu ze-cyclic kwisantya sokusebenza kunye nesantya sokutya, isisombululo sokugqibela esipheleleyo kwingxaki ye-resonance.
Ubunzima bokupholisha:I-viscosity ye-workpiece inkulu, ekhokelela kwi-debris enzulu yezinto ezincamathelayo zevili lokusila, kwaye akunakwenzeka ukugawula ngokuqhelekileyo. Ekugqibeleni, iskimu sokugqiba i-lathe sisetyenziselwa ukugqiba imfuno yokugqiba umphezulu we-RA0.6um.
7.Ingxelo yezinto eziphathekayo
8.Ulungelelwaniso lokuMeta (umlinganiselo weCMM)
