Ukuhlolwa kwe-Ultrasonic kuyindlela evame ukusetshenziswa yokuthola amaphutha angaphakathi kuma-cylindrical forgings. Ukuze kuqinisekiswe imiphumela yokuhlola ephumelelayo, kunezinyathelo ezithile ezibalulekile okufanele zilandelwe.
Okokuqala, ukuhlolwa kwe-ultrasonic kufanele kwenziwe kuma-cylindrical forgings ngemuva kokwelashwa kokugcina kwe-austenitizing kanye nokwelashwa kokushisa okushisa ukuze kutholwe izakhiwo zemishini ze-forgings. Kunjalo, njengoba kudingekile, ukuhlola kungenziwa futhi ngaphambi noma ngemva kwanoma yikuphi ukucindezeleka okudambisa ukwelashwa okushisa.
Okwesibili, lapho kwenziwa ukuhlolwa kwe-ultrasonic, i-radial incidence ultrasonic beam kufanele isetshenziselwe ukuskena okuphelele. Lokhu kusho ukuthi amagagasi e-ultrasonic kufanele abe yisigameko se-perpendicular ebusweni obungaphakathi kusuka ku-probe ukuqinisekisa ukutholakala kwayo yonke indawo yangaphakathi. Khonamanjalo, ukuze kuthuthukiswe ukunemba kokutholwa, kufanele okungenani kube nokugqagqana okungu-20% kobubanzi be-chip ye-probe phakathi kokuskena okuseduze.
Ukwengeza, ama-forging angaba sesimweni sokuma noma ahlolwe ngokuwabeka ku-lathe noma i-roller ukuze ajikeleze. Lokhu kuqinisekisa ukuthi yonke indawo engaphakathi ithola ukumbozwa okwanele kokutholwa.
Phakathi nenqubo ethile yokuhlola, ukunakwa kufanele kukhokhwe ekubushelelezini nasekuhlanzekeni kwendawo yangaphakathi ye-forging. Ingaphezulu akufanele libe nemihuzuko, isikhumba se-oxide esixekethile, imfucumfucu, noma ezinye izinto zangaphandle ukuvimbela ukuphazamiseka kokusakazwa nokwamukela amagagasi e-ultrasonic. Ukuze kuzuzwe lokhu, kuyadingeka ukusebenzisa i-ejenti yokuhlanganisa ukuxhuma ngokuqinile i-probe endaweni engaphakathi ye-forging ukuqinisekisa ukudluliswa okuphumelelayo kwe-ultrasonic.
Mayelana nemishini, imishini yokuhlola i-ultrasonic ihlanganisa imishini yokuhlola i-ultrasonic, ama-probe, ama-coupling agents, namabhulokhi okuhlola. Lawa mathuluzi awukhiye wokuqinisekisa ukunemba nokuthembeka kwenqubo yokuhlola.
Okokugcina, lapho kwenziwa ukuhlolwa kwe-ultrasonic, ukwamukelwa kwama-forging kungahlulelwa ngokusekelwe enanini lamaphutha, ubude besici, isikhundla, noma inhlanganisela yalokhu okuthathu, njengoba kudingekile. Phakathi naleso sikhathi, ngenxa yokuba khona kwamakhona ayindilinga kanye nezinye izizathu zokuma kwendawo esinyathelweni se-cylindrical forgings, akudingekile ukuhlola izingxenye ezithile ezincane zendawo yangaphakathi yembobo.
Kafushane, ukuhlolwa kwe-ultrasonic kuyindlela ethembekile yokuthola amaphutha angaphakathi angaphakathi kuma-cylindrical forgings. Ukulandela lezi zinyathelo zokuphepha ezingenhla, kuhlanganiswe nemishini efanele kanye nobuchwepheshe, kungaqinisekisa ikhwalithi nokwethembeka kokufogiwe futhi kuhlangabezane nezidingo zokuhlola ezihambisanayo.
