Nokuti stainlessforgings dzesimbianowanzo shandiswa munzvimbo yakakosha yemuchina, saka iyo yemukati mhando yestainlessforgings dzesimbikunokosha zvikuru.Nokuti unhu hwemukati hwetsvinaforgings dzesimbihaigone kuyedzwa nenzira inonzwisisika, saka yakakosha yemuviri nemakemikari yekuongorora nzira dzinoshandiswa kuyedza.

Kutanga, iyo mechanical properties ye forgings
Iyo mechanical properties yeforgingszvinotemerwa zvinoenderana nechigadzirwa zvinodiwa.Nzira dzekuyedza dzakakamurwa kuita kuomarara bvunzo, tensile bvunzo, kukanganisa bvunzo uye kuneta bvunzo.
1. Kuoma bvunzo
Kuomarara ndiko kushomeka kwekupokana kwenzvimbo yezvinhu, indekisi inoyera zvinhu zvesimbi zvakapfava zvakasimba.Kuomarara uye zvimwe zvemakanika zvivakwa zvine humwe hukama hwemukati, saka mamwe ma mechanic zvimiro zvezvinhu zvinogona kufungidzirwa nekuomarara kukosha.Kuomarara bvunzo haidi kugadzirira akakosha masampuli, uye haizoparadze iyo sampuli, saka kuomarara bvunzo ndiyo inonyanya kushandiswa mukugadzirwa kwemakanika midziyo yekuyedza nzira.
Inowanzo shandiswa nzira dzekuomarara dzekuyedza uye hunhu hwakasiyana ndeidzi: Brinell kuomarara (HB), Rockwell kuomarara (HRC), Vickers kuomarara (HV), Shore kuomarara (HS), uye inoenderana nehukukutu tester.
2. Tensile bvunzo
Nekuisa iyo inorema mutoro kune imwe sampuli yeimwe chimiro nemuchina wekutemesa, iyo yakaenzana elongation kushushikana, goho poindi, kusimba kwesimba, kureba uye kudzikiswa kwechikamu chesimbi zvinhu zvinoyerwa.
3. Muedzo wemigumisiro
Iko kusimba kwesimbi kwakawanikwa kuburikidza nekushandisa high-speed pendulum kuti iite sampuli ine notch.
4. Kuneta bvunzo
Muganho wekuneta uye simba rekuneta kwesimbi rinogona kuyerwa mushure mekudzokororwa kana kushandura kushushikana.
Chechipiri, kusingaparadzi kuongororwa kwekugadzira
Nondestructive bvunzo inogona kukamurwa kuita radiographic kuyedza, ultrasonic bvunzo, magineti particle test, seepage test uye eddy ikozvino kuyedza.Forgings anowanzo shandiswa mukuyedzwa kwe ultrasonic uye magineti particle test.
1. Ultrasonic kuongorora
Ultrasonic wave (frequency kazhinji yakakura kupfuura 20000Hz) icharatidza uye inopesana pane iyo interface yezvinhu zvakasiyana.Naizvozvo, kana paine hurema hwezvinhu zvakasiyana mumidziyo yakasimba, wave reflection uye attenuation inogadzirwa.Kuvapo kwekuremara kunogona kutongwa nemasaisai masaini.
Zvehombe nepakatiforgings, ultrasonic bvunzo ndiyo imwe yedzakakosha nzira dzekusaparadza kuyedza.
2. Magnetic particle kuongorora
Kukanganisa kwakadai sekutsemuka, pores uye nonmetallic inclusions pamusoro uye padyo nepamusoro pekugadzira zvinogona kuongororwa nemagnetic particle inspection.Nekuda kwemidziyo yayo yakapusa, kushanda kuri nyore uye kunzwisiswa kwakanyanya, nzira iyi inowanzoshandiswa kuyedza madiki uye epakati-saizi mafogi anogadzirwa muhuwandu.
Tatu, simba rakaderera uye bvunzo yekutsemuka
Kuongororwa kwesimba kwakaderera ndiyo sampuli mushure meimwe chiyero chekugadzirisa, uyezve neziso rakashama muna 10 ~ 30 nguva yegirazi rinokudza kutarisa sampuli, kuitira kuti uwane hurema hwesimbi isina tsvina forgings.Streamline, dendrite, loose, naphthalene, kutsemuka kwedombo uye kumwe kukanganisa kunogona kuongororwa nekucheka wafer samples uye acid etching.Kuti uone kuparadzaniswa, kunyanya kugoverwa kusina kuenzana kwesulfide, sulfur kudhinda nzira inoshandiswa.
Zvina, kuongorora kwepamusoro-simba
Stainless simbi forgings ichaitwa mune imwe sampuli pasi pe microscope kutarisa mukati mekugadzira (kana kuputsika) pane mamiriro esangano kana microscopic defects.Chimiro chemukati uye inclusions kugovera kwekugadzira kunogona kuongororwa nekucheka longitudinal sampuli.Kuremara kwepamusoro senge decarburization, coarse-grained, carburized uye akaomeswa maseru anogona kuongororwa nekucheka transverse samples.
