Yenziwe ngentsimbi eshayinayoLuhlobo lwensimbi, intsimbi ibhekisa kwinani lekhabhoni (c) kwezi pesenti ze-2 kubizwa ngokuba yintsimbi, ngaphezulu kwe-2% yintsimbi. Intsimbi kwinkqubo yokunyibilikisa ukongeza i-chromium (CR), i-Nickel (Ni), i-manganese (i-silicon (i-7), i-selicon (MN) kunye nezinye izinto zokwabelana ngentsimbi Ukunganyangeki kohlobo (oko kukuthi, hayi rust) sihlala sithi intsimbi engenasiseko.
Intsimbi engenasibala kwinkqubo yokunyibilikisa, ngenxa yokongezwa kwezinto ezahlukeneyo ezahlukeneyo, iintlobo ezahlukeneyo zenani labantu elahlukileyo. Iimpawu zayo nazo zahlukile, ukuze ukwahlula isithsaba ngamanani ahlukeneyo ensimbi.
Ukwahlulahlulwa okuqhelekileyo kwentsimbi engenasimo
1. I-304 intsimbi engenanto
Intsimbi engama-304 yeyona nto ixhaphakileyo yentsimbi yentsimbi, njengentsimbi esetyenziswa ngokubanzi, ixhathise kakuhle, ukumelana nobushushu, amandla obushushu obuphantsi, kunye namalungu obuchwephesha obuphantsi; Ukuhamba, ukugoba kunye namanye amandla e-thermal yenkqubo kulungile, akukho nto ishushu kakhulu kunyango (Akukho magetic, emva koko sebenzisa ubushushu -196 ~ 800 ~).
Ubungakanani besicelo: Amanqaku aseKhaya (1, 2 IKibliwa, iikhabhathi, imibhobho yangaphakathi, izifuba zamanzi, iibhastile); Iinxalenye ezenzekelayo (i-Windshield Wiper, Muffler, iiMveliso zokuBumba); Izixhobo zonyango, izinto zokwakha, ikhemistri, ishishini lokutya, ezolimo, amalungu enqanawa
I-2. I-304l intsimbi engenasitayile (l yikhabhoni esezantsi)
Njengomthi ophantsi wekhabhoni 304, KuRhulumente Jikelele, ukumelana nokunganyangeki kwe-surrosion kunye ne-304 ngokufanayo, kodwa emva nje kokupheliswa komda wobubi obuhle kakhulu; Kwimeko yokungabikho konyango lobushushu, unokugcina ukunganyangeki kakuhle kwengqondo, ukusetyenziswa kobushushu -196 ℃ ~ 800 ℃.
Umda wesicelo: Isetyenziswe kwishishini lekhemikhali, amalahle kunye nepetroleum ngeemfuno eziphakameyo zokunganyangeka koomatshini bokuphuma, ukwakha izinto zobushushu kunyango lobushushu.
I-3. 316 Intsimbi engenasimo
316 Intsimbi engenasibala ngenxa yongezwa kweMolybdenum, ngokuchasene nokunganyangeki kwe-corosion yayo, i-Trerosion Sorrosion kunye namaqondo obushushu amaqondo obushushu alungile, angasetyenziswa phantsi kweemeko ezinzima; Umsebenzi obalaseleyo oqaqambileyo (ongenayo).
Ubungakanani besicelo: Izixhobo zamanzi olwandle, iikhemikhali, iDystuff, ezenza iPhepha, i-OXALINC ACID, isichumisi kunye nezinye izixhobo zemveliso; Iifoto, ishishini lokutya, amaziko onxweme, iintambo, iintonga zeCD, ii-bolts, amantongomane.
I-4.
Njengoluhlu lwekhabholo ye-316 yentsimbi, ukongeza kwiimpawu ezifanayo ngentsimbi engama-316 yentsimbi, ukumelana nomda wengqolowa kuhle kakhulu.
Ubungakanani besicelo: Iimfuno ezizodwa zokuxhathisa iimveliso zomda wezomda.
Ukuthelekisa intsebenzo
1. Ubume bemichiza
I-Staiels 316 kwaye i-316l yi molybdenum enezini ezingenazibala. Umxholo we-molybdenum we-316l intsimbi engenasitali iphakamile kancinane kune-316 yentsimbi engenasibala. Ngenxa ye-molybdenum kwintsimbi, intsebenzo iyonke yentsimbi ibhetele kune-310 kunye ne-304 yezitho ezingenasiseko. Phantsi kweemeko zobushushu obuphezulu, xa uxinzelelo lwe-sulfuric acid lingaphantsi kwe-15% nangaphezulu kwe-85%, i-316 izistithi ezingenasiseko zinoluhlu olubanzi lokusebenzisa. Intsimbi engama-316 ingenalo ineepropathi ezintle kwaye i-chloride ye-erosion, ngoko ke isetyenziswa kwiindawo zaselwandle. I-316l intsimbi engenasitali inomxholo wekhabhoni ephezulu ye-0.03. Ilungele izicelo apho i-sport-swil ye-weld ayinakwenzeka kwaye apho kuyafuneka khona ukuphiliswa kwemveliso ephezulu.
2. CoUkunganyangeki kwe-rasion
Ukunganyangeki kwentshukumo ye-316 intsimbi engenasibala kungcono kuneso sensimbi engama-304. Inomchasi ofanelekileyo kwimveliso yemveliso yePulp nePhepha. Kunye ne-316 intsimbi engenasibala ikwachasa ukumelana nomoya onobukrelekrele. Ngokubanzi, i-304 yentsimbi engenasinqwanga kunye ne-316 intsimbi engenasibala kwinkcaso yeekhemikhali zomehluko omncinci, kodwa kwimithombo yeendaba ezithile zahlukile.
Intsimbi engama-304 yaphuhliswa, eyayinolwazelelelo ekubonakaliseni ukuthengisa kwiimeko ezithile. Ukongeza i-2-30% ye-Molybdenum inciphise le mvakalelo, ikhokelela kwi-316. Ukongeza, ezi molybdenum ezongezelelweyo zinokunciphisa ukuvela kwe-acids eshushu.
Intsimbi engama-316 iphantse yaba yinto esezantsi kwishishini lokutya kunye nemveliso. Ngenxa yokunqongophala kwe-molybdenum ye-molybdenum kunye nomxholo ophezulu we-nickel ngentsimbi engama-316 yentsimbi, intsimbi engama-316 iphosakele kunentsimbi engama-304.
Ukuthambisa i-corrosion yinto ebangelwa yi-corrosion efakwe kumphezulu wensimbi engenasimo, nto leyo ngenxa yokunqongophala kweoksijini kwaye ayinakwenzakaliswa yi-omerium ye-chromium oxide. Ingakumbi kwiiValve ezincinci, kukho ithuba elincinci lokubekwa kwi-disc, ngoko ke inkobe inqabile.
Kwiintlobo ngeentlobo zamanzi aphakathi (amanzi ashiyo amanzi, amanzi okusela, amanzi emfula, amanzi olwandle, njl njl. Phezulu kakhulu, ngeli xesha intsimbi engenasimo ilungileyo ifanelekile ngakumbi. Kwiimeko ezininzi, ukumelana nokunganyangeki kwentsimbi ye-304 yentsimbi engenasibala kunye ne-316 i-stainess ayifani, kodwa kwezinye iimeko kunokubahluke kakhulu, kufuneka kuhlaziywe kwimeko-yecala.
3. Ukumelana nobushushu
Intsimbi engama-316 inesitayile esingenanto inesidima esihle sokunganyangeki ekusetyenzisweni kwe-1600 idigri kwaye isebenzise ngokuqhubekayo nge-1700 degrees. Kuluhlu lwama-800-1575 degrees, kungcono ukungaphumi kwi-316 yentsimbi, kodwa kuluhlu lwamaqondo obushushu asetyenziswa ngentsimbi engama-316 intsimbi engenasibala, intsimbi engenasiseko ichazekile. I-316l intsimbi engenasitali ichaze ngakumbi kubungakanani be-carbide kune-316 intsimbi engenasibala, enokusetyenziswa kuluhlu lobushushu olungasentla.
4. Unyango lobushushu
I-ANALY yenziwa kuluhlu lobushushu lwe-1850 ukuya kuma-2050 degrees, elandelwa ngokutsha ngokutsha, emva koko kuphononongwa ngokukhawuleza. Intsimbi engama-316 ayinakuthandwa ukuze iqaqadeke.
5. I-welding
Intsimbi engama-316 engenamandla amahle afanelekileyo. Zonke iindlela ezisemgangathweni ze-welding zingasetyenziselwa i-welding. Ngokwenjongo ye-welding, i-316cb, i-316l okanye i-309cb ye-Staining yentsimbi okanye i-electrode ingasetyenziselwa i-welding. Ukuze ufumane owona msebenzi ubalaseleyo wokunganyangeki, icandelo le-welding le-316 lensimbi kufuneka idityaniswe emva kwe-welding. I-Post Alloing ayimfuneko ukuba i-316l intsimbi isetyenzisiwe.
I-HikelokItyhubhu yentsimbi engenaloSebenzisa i-316l. Ezinye izinto zetyhubhu kunye neevila zihlala zisebenzisa izinto ezingama-316.
