Zvishandiso zvesimbi isina ngura zvinoshandiswa zvakanyanya mumaindasitiri akadai se petrochemical, aerospace, kugadzira magetsi, kugadzira chikafu, uye marine engineering. Zvikamu izvi zvinozivikanwa nekusimba kwazvo, kuramba ngura, uye kugara kwenguva refu mumamiriro ezvinhu akaoma. Zvisinei,kuvimbika kwesimbi isina ngurahazvingotsamiri pahukuru hwekunze chete asiwo pahukuru hwavohunhu hwemukati.
Zvikanganiso zvemukati zvakaita sekutsemuka, maburi, zvinhu zvinosanganisirwa, kana kupatsanurwa—kana zvikasaonekwa—zvinogona kutungamira mukukundikana kukuru mubasa. Nokudaro,kuongorora kwemhando yemukatiidanho rakakosha mukugadzirwa uye kuvimbisa mhando. Rinovimbisa kuti zvigadzirwa zvakagadzirwa zvinosangana nezvinodiwa zvemakanika, zvesimbi, uye zvekuchengetedza zvinodiwa nezvinodiwa nenyika dzese nevashandisi vekupedzisira.
Chinyorwa chino chinoongorora nzira dzakakosha uye kukosha kwekuongorora hunhu hwemukati mukugadzira simbi isingatsvi, zvichiratidza nzira dzakanakisa dzeindasitiri uye misimboti yekudzora hunhu inoteverwa nevatengesi vanovimbwa navo vakaita sesakysteel.
Nei Hunhu Hwemukati Huchikosha
Kunyangwe kana pamusoro pacho pakaita sepasina chakaipa, simbi isina ngura inogona kunge iine zvikanganiso zvakavanzika zvinokanganisa:
-
Simba remakanika

Maikorosikopu yemaziso
-
Maikorosikopu yemaerekitironi ekuskena (SEM)
Kukosha:
Zvakakosha pakunzwisisa maitiro ezvinhu uye kufanotaura mashandiro enguva refu.
Yakashandiswa pasakysteelpanguva yekugadzira chigadzirwa kana maitiro ekukodzera vatengi.
4. Kuedza Kupinda Mudhayi uye Kuedza Magnetic Particles (Rutsigiro rwezvikanganiso zvemukati zviri pedyo nepamusoro)
Kunyangwe zvichinyanya kushandiswa pamusoro pevhu, zvinogona kubatsira kuona zvikanganiso zviri pasi pevhu pedyo nekunze kwesimbi dzisina ngura.
-
Kuongororwa kweDye Penetrant (DPT):Inoburitsa mitswe yakavhurika pamusoro uchishandisa dhayi nemugadziri
-
Kuedzwa kweMagineti Particle (MPI):Inoshandiswa chete pasimbi dzisina ngura dzine magineti dzakadai se410 kana 420
Nzira idzi dzinowanzo wedzera kuongororwa kwakadzama kwemukati.
5. Kuumbwa kweMakemikari uye Kuongorora Kuparadzaniswa kweElemental
Pfupiso:
Kusimbisa kuenderana kwemukati mezvinhu zvemakemikari kwakakosha pakudzivirira ngura uye hunhu hwemakanika.
Nzira dzakashandiswa:
-
Optical Emission Spectroscopy (OES)
-
Kupenya kweX-ray (XRF)
-
Kuongororwa kweGlow Discharge Spectroscopy (GDS)
Nzvimbo dzekutarisa:
-
Kuona kupatsanurwa kwenzvimbo dzakakura dzekuvaka
-
Kuve nechokwadi chekuti zvinhu zvose zvinoenderana kubva pamusoro kusvika pakati
sakysteelinoita ongororo yekuumbwa kwayo isati yatanga uye yapera kuti ionekwe kuti yanyatso teverwa zvakanaka here.
6. Kuyera Kuoma Kwemapu uye Kuedza Kuyambuka Chikamu
Chinangwa:
Kuongorora kufanana kwehunhu hwemakanika mukati mekugadzira.
Maitirwo azvo:
-
Mienzaniso yakakamurwa inoedzwa pakadzika kwakasiyana-siyana
-
Kuverengwa kwekuoma (Brinell, Rockwell, kana Vickers) kwakagadzirwa
Inobatsira kuona kusashandiswa zvakanaka kwekupisa kana kutonhora kwemidziyo mikuru.
Maitiro ekugamuchira uye Maitiro
Mhedzisiro yekuongorora kwemukati inofanirwa kuenderana nezvinodiwa neindasitiri. Mitemo yakafanana inotaurwa inosanganisira:
-
ASTM A388- UT yekugadzira simbi
-
EN 10228- NDT yesimbi yekuputira
-
Chikamu cheASME VIII- Maitiro ekugadzira midziyo yekumanikidza
-
API 6A / 6D- Mitemo yeindasitiri yemafuta negesi
Matanho ekugamuchirwa anoenderana nezvinodiwa nevatengi, kukosha kwechikamu, uye njodzi dzekushandisa.
Magwaro uye Kutevedza
At sakysteel, kuongororwa kwese kwemhando yemukati kwakanyorwa sechikamu chehurongwa hwekudzora mhando, kusanganisira:
-
Mishumo yebvunzo dzeUltrasonic
-
Mafirimu eX-ray kana marekodhi edhijitari
-
Mifananidzo ye microstructure
-
Machati ekuoma uye kuumbwa kwemakemikari
-
Kutevedza nhamba yekupisa
-
Zvitupa zveMiedzo yeChigayo (MTCs)
-
EN 10204 3.1 kana 3.2 chitupa (sezvinodiwa)
Izvi zvinoita kuti vatengi vaonekwe pachena uye vave nechivimbo chekuti chigadzirwa chavo chakavimbika.
Kana Kuongorora Kwemukati Kwakakosha
Kuongorora mhando dzemukati kwakakosha zvikuru kune:
-
Maflange asina kusimba akaongororwa nekumanikidzwa
-
Mapombi ekuisa pombi nemaimpeller
-
Madhisiki eturbine nemarotor
-
Zvikamu zvenyukireya nendege
-
Zvikamu zvepasi pegungwa nekunze kwegungwa
Mumashandisirwo aya, zvikanganiso zvisingaonekwe zvinogona kutungamira mukurasikirwa kunodhura kana kukundikana kunotyisidzira hupenyu.
Mhedziso
Kuongororwa kwemhando yesimbi isina ngura mukati chinhu chisingakurukurwi mukugadzirwa kwemazuva ano. Kuburikidza nenzira dzakadai sekuongorora kwe ultrasound, kuongorora x-ray, metallography, uye mapping yehukukutu, vagadziri vanogona kuona matambudziko emukati asati ava matambudziko ekushanda.
Nekuwedzera kuri kuda kwezvinhu zvakagadzirwa zvine simba guru mumaindasitiri akakosha, maitiro ekuvimbisa mhando anofanirwa kuve akanyatsorongeka, akaenzana, uye anoteverwa.
sakysteelinodada nekupa simbi isina ngura isina kusimba isina kutaridzika zvakanaka chete asi ine hutano mukati. Kubva pakuongororwa kwezvinhu zvakagadzirwa kusvika pakusimbiswa kwekupedzisira, chigadzirwa chega chega chinoongororwa uchishandisa matekiniki epamusoro ekuongorora uye chinounzwa nemagwaro emhando yepamusoro.
