Xa usiva I-AMS 5387, into yokuqala edla ngokufika engqondweni lelinye icwecwe elinobushushu obuphezulu. Ngumgibe oqhelekileyo lowo. Ngokwenyani, ukujongana nale nkcazo ye-cobalt-based superalloys, ngakumbi iStellite 6, incinci malunga netafile yokwakheka kweekhemikhali kwaye ngaphezulu malunga negritty, izandla kumdaniso phakathi kwesiseko kunye nevenkile yomatshini. Yimathiriyeli ethembisa ukunxiba okugqwesileyo kunye nokumelana nomhlwa ukuya kutsho kwintoni, 800°C? Kodwa isithembiso esisephepheni kunye nenxalenye esesandleni sakho ngamahlabathi amabini ahlukeneyo. Ndibone iiprojekthi ezininzi kakhulu zikhubeka ngokunyanga I-AMS 5387 njengento elula endaweni. Ayiyo. Yonke ifilosofi yokwenziwa kufuneka itshintshe.
Inyani yoMgangatho weFoundry
Makhe sithethe ngecala lokuphosa kuqala. I-AMS 5387 Isixhobo, esihlala sigalelwa njenge-Stellite 6, sisilo sokuphoswa ngokucocekileyo. I-cobalt ephezulu kunye nomxholo wechromium ithetha ukuba ithanda ukwenza izigaba ezinzima, ezinqabileyo ukuba izinga lokupholisa alilungile. Sifunde oku ngendlela enzima kwiminyaka eyadlulayo kwiprojekthi yesitulo sevalvu. Imizobo ibifuna I-AMS 5387, kwaye safumana i-alloy. Ukuqala kokubunjwa kweqokobhe kujongeka kugqibelele-ukugqiba okuhle komphezulu. Kodwa ngexesha lovavanyo loxinzelelo, iindawo ezininzi zaphuhliswa ukuqhekeka kweenwele. Ayizicacelanga, kodwa uhlobo olufumana ngedayi yokungena. Ingxaki? Isango lethu lokungena kunye nenkqubo yokunyuka, efanelekileyo ngokugqibeleleyo kwiintsimbi eziqhelekileyo ezingenasici, azizange zithathele ingqalelo kolu luhlu lokuqina olumxinwa kakhulu. Sasisondla ngokungalunganga ukucutheka, sidala amanqaku oxinzelelo lwangaphakathi.
Apha kulapho amava exesha elide e-Foundry eba yinto engaxoxiswana ngayo. Inkampani efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye neminyaka engamashumi amathathu kwi-shell kunye ne-investment casting, iya kuba neeparitha zenkqubo-ubushushu be-mold preheat, isantya sokuthulula, iiprothokholi zokupholisa emva kokupholisa-esele zicofelwe kwezi ngxubevange ezibuthathaka. Ayisiyonto uyifumanayo kwi-spec. Lulwazi lwezizwe kumgangatho wevenkile. Kuba I-AMS 5387, umahluko phakathi kokuphoswa kwesandi kunye nemfumba ye-scrap ihlala ihla kwindlela olawula ngayo iphrofayili ye-thermal ukusuka kwi-ladle ukuya kwigumbi lokupholisa. Awunakusuka nje ube yiphiko.
Obunye ubuqili bubunzima be-as-cast. I-AMS 5387 ixela uluhlu, kodwa imo ye-as-cast ihlala kwindawo ephezulu. Kuhle kakhulu ukuxhathisa ukunxiba, kodwa ngoko nangoko kubonisa umngeni kwinqanaba elilandelayo: umatshini. Ukuba awulungelelanisi ubunzima bokuphosa kunye neqela lakho lomatshini, ubamisela ilizwe lokwenzakala ngokunxitywa kwesixhobo kwangaphambi kwexesha. Kukusilela kwe-handoff yakudala phakathi kwamasebe.
Machining: Apho ithiyori idibana Bit Tool
Apha kulapho umlinganiswa wokwenyani I-AMS 5387 ibonisa. Machining Stellite 6 akafani machining 304 okanye nokuba 17-4 PH stainless. Isebenza-nzima ngamandla. Uthatha ukusikwa, kwaye umphezulu owuveze nje uba nzima kunesixhobo esingaphantsi. Ukuba iifidi zakho kunye nezantya ziyoyikeka, uyapholisha kwaye uqinisa indawo ngokudlula ngakunye, okukhokelela kukusilela kwesixhobo esiyingozi. Undoqo kukungena ngaphantsi kwaloo maleko owenziwe nzima. Udinga iharika elungileyo, izixhobo ezibukhali-i-carbide okanye i-ceramic, hayi i-HSS-kwaye kufuneka ugcine izinga lokutya elingaguqukiyo, eliqinisekileyo. Ukuthandabuza lutshaba.
Ndikhumbula icandelo lokulungiswa kwe-thermal esenze ngoomatshini ukusuka kwi- I-AMS 5387 ukuphosa. Ijometri yayibandakanya iindonga ezibhityileyo kunye neepokotho ezinzulu. Umzamo wethu wokuqala wasebenzisa i-conservative, i-high-speed-speed-milling strategy kunye nee-stepovers ezincinci. Yaba yintlekele. Izixhobo zichotshoziwe rhoqo, kwaye inxalenye igqwethekile kwigalelo lobushushu. Sabuya umva, satshintshela kwinkqubo yesibambisi sixhobo esingqongqo ngakumbi, sanciphisa isantya sokuphotha, kwaye sanyusa kakhulu isondlo ngezinyo ngalinye. Kwavakala kuchasene nokuba ndlongondlongo, kodwa kwasebenza. Ukwakheka kwetshiphu kutshintshile ukusuka kuthuli, umlambo omenyezelayo ukuya kwitshiphu ejiyileyo, egobileyo ethwala ubushushu. Ukugqiba kwenxalenye kunye nokuzinza komda kwakugqibelele. Sifunda ntoni? Esi sixhobo sifuna intlonipho, kodwa hayi unyango lweglavu yabantwana. Ifuna ukusikwa okuqinisekileyo, okunolwazi.
Ukupholisa yenye into ekuxoxwa ngayo. Abanye bafunga ngoxinzelelo oluphezulu ngokusebenzisa isixhobo sokupholisa ukulawula ubushushu kunye nokwaphula iitshiphusi. Abanye, ndibandakanyiwe, baye baneziphumo ezilungileyo nge-heavy-duty emulsion flood coolant, ngaphandle kokuba iqondiswe ngokugqibeleleyo kwi-interface yokusika. Injongo kulawulo lwe-thermal kunye nokuthambisa. Eyokwemba kunye nokucofa I-AMS 5387, nangona kunjalo, ndiqinile kwinkampu yokupholisa yoxinzelelo oluphezulu. Yeyona ndlela kuphela yokukhupha iitshiphusi kwimingxunya enzulu kwaye uthintele isixhobo kwi-welding ukuya kwi-workpiece.
