Ngoba ibalaizinsimbi zensimbizivame ukusetshenziswa endaweni ukhiye umshini, ngakho izinga yangaphakathi engagqwaliizinsimbi zensimbikubaluleke kakhulu.Ngoba ikhwalithi yangaphakathi ye-stainlessizinsimbi zensimbiayikwazi ukuhlolwa ngendlela enembile, ngakho-ke kusetshenziswa izindlela ezikhethekile zokuhlola ngokomzimba namakhemikhali ukuze kuhlolwe.

Okokuqala, izakhiwo mechanical of forgings
Izici zemishini yeama-forgingskunqunywa ngokwezidingo zomkhiqizo.Izindlela zokuhlola zihlukaniswe ukuhlolwa kokuqina, ukuhlolwa kwe-tensile, ukuhlolwa komthelela kanye nokuhlolwa kokukhathala.
1. Ukuhlolwa kokuqina
Ubulukhuni buwukumelana nokuguquguquka kobuso bezinto ezibonakalayo, buyinkomba ekala izinto zensimbi ezithambile zibe nzima.Ukuqina nezinye izici zokuwumshini zinobudlelwano obuthile bangaphakathi, ngakho-ke ezinye izakhiwo zemishini zingalinganiswa ngevelu yobulukhuni.Ukuhlolwa kokuqina akudingi ukulungisa amasampula akhethekile, futhi ngeke kucekele phansi isifanekiso, ngakho ukuhlolwa kokuqina yikho okuvame ukusetshenziswa ekukhiqizeni indlela yokuhlola impahla eyimishini.
Izindlela zokuhlola ubulukhuni ezisetshenziswa kakhulu namanani ahlukene yilezi: Ukuqina kwe-Brinell (HB), ukuqina kwe-Rockwell (HRC), ukuqina kwe-Vickers (HV), ukuqina koShore (HS), kanye nomhloli wokuqina ohambisanayo.
2. Ukuhlolwa kwe-Tensile
Ngokufaka umthwalo oqinile esibonelweni somumo othile ngomshini oqinile, ukucindezelwa kwe-elongation okulinganayo, iphuzu lesivuno, amandla aqinile, ukunwetshwa kanye nokunciphisa ingxenye yezinto zensimbi kuyalinganiswa.
3. Ukuhlolwa komthelela
Ukuqina komthelela kwensimbi kutholwe kusetshenziswa i-pendulum enesivinini esiphezulu ukuze kuthinte isifanekiso ngenotshi.
4. Ukuhlolwa kokukhathala
Umkhawulo wokukhathala namandla okukhathala kwensimbi kungalinganiswa ngemva kokucindezeleka okuphindaphindiwe noma ukushintshana.
Okwesibili, ukuhlolwa okungabhubhisi kokufoja
Ukuhlola okungonakalisi kungahlukaniswa ngokuhlolwa kwe-radiographic, ukuhlolwa kwe-ultrasonic, ukuhlolwa kwezinhlayiyana kazibuthe, ukuhlolwa kwe-seepage kanye nokuhlolwa kwamanje kwe-eddy.Ama-Forgings avame ukusetshenziswa ekuhlolweni kwe-ultrasonic nokuhlolwa kwezinhlayiyana kazibuthe.
1. Ukuhlolwa kwe-Ultrasonic
Igagasi le-Ultrasonic (imvamisa imvamisa ingaphezulu kuka-20000Hz) izokhombisa futhi ihlanekezele kusixhumi esibonakalayo sezinto ezahlukahlukene.Ngakho-ke, uma kukhona ukukhubazeka kwezinto ezihlukahlukene ezintweni eziqinile, ukubonakaliswa kwamagagasi kanye nokunciphisa kuzokwenziwa.Ukuba khona kokukhubazeka kungahlulelwa ngamasignali e-waveform.
Ngenkulu nephakathiama-forgings, ukuhlolwa kwe-ultrasonic kungenye yezindlela ezibalulekile zokuhlola okungonakali.
2. Ukuhlolwa kwezinhlayiyana kazibuthe
Amaphutha afana nokuqhekeka, ama-pores kanye ne-nonmetallic inclusions phezu naseduze kwendawo yokubumba kungahlolwa ngokuhlola izinhlayiya kazibuthe.Ngenxa yemishini yayo elula, ukusebenza okulula kanye nokuzwela okuphezulu, le ndlela ivame ukusetshenziselwa ukuhlola ama-die forging amancane naphakathi akhiqizwa ngobuningi.
Okwesithathu, amandla aphansi nokuhlolwa kokuphuka
Ukuhlolwa kwamandla aphansi kuyisampula ngemva kwenani elithile lokucutshungulwa, bese kuba ngeso lenyama izikhathi ezingu-10~30 zengilazi yokukhulisa ukuze kuhlolwe isampula, ukuze kutholwe ukukhubazeka kokufogetha kwensimbi engagqwali.I-Streamline, i-dendrite, i-loose, i-naphthalene, ukuphuka kwamatshe nokunye ukukhubazeka kungahlolwa ngokusika amasampula angama-wafer kanye ne-acid etching.Ukuze kutholakale ukuhlukaniswa, ikakhulukazi ukusabalalisa okungalingani kwe-sulfide, indlela yokuphrinta isulfure isetshenziswa.
Okwesine, ukuhlolwa kwamandla aphezulu
Izimbotshana zensimbi engagqwali zizokwenziwa isampula ethile ngaphansi kwesibonakhulu ukuze kuhlolwe ukwakheka kwangaphakathi (noma ukuphuka) esimweni senhlangano noma amaphutha amancane.Isakhiwo sangaphakathi kanye nokusatshalaliswa kokufakwa kokubumba kungabhekwa ngokusika isampula ye-longitudinal.Amaphutha angaphezulu okufana nokususwa kwe-carburization, izendlalelo eziqinile, eziqinile neziqinile zingahlolwa ngokusika amasampula aphambene.
