I-Pressure Vessel Plates Amapuleti ensimbi asetshenziswa ekwenzeni ama-boilers we-steam, imikhumbi yokucindezela nezinye izingxenye zesakhiwo semikhumbi yokucindezela.Ngenxa yokuthi lolu hlobo lwepuleti lensimbi lunomfutho othile womoya nomfutho wamanzi, kanye nendawo yokusetshenziswa kwamazinga okushisa ahlukene, njengezinga lokushisa eliphakeme, eliphakathi nendawo neliphansi, njll., izidingo zalolu hlobo lwepuleti lensimbi ziqinile uma kuqhathaniswa.
Ukusakazwa kokuhlela isingeniso somkhiqizo
(1) Incazelo: Ngaphezu kokudinga amandla nokuqina okuthile, impahla nayo iyadingeka ukuze ifane, futhi amaphutha ayingozi alinganiselwe.
(2) Izinhlobo: Ngokwezigaba zezingxenye, zingahlukaniswa zibe izigaba ezimbili: amapuleti ensimbi ye-carbon kanye namapuleti ensimbi ye-alloy;ngokwezigaba zamandla, ingahlukaniswa ngamapuleti ensimbi aphezulu, aphakathi nendawo naphansi;Ipuleti lensimbi eligqwalile.
Ugqinsi lwepuleti lomkhumbi wengcindezi ngokuvamile luphakathi kuka-5 kuya ku-200mm, futhi isikhathi sihlukaniswa ngezicaciso ezimbalwa zokujiya.Uhlu lwamazinga kazwelonke osayizi beshidi abanconyiwe kanye nokuchezuka okuvumelekile.Ikhwalithi yokubukeka (1) Umumo wepuleti lensimbi: njenge-camber, flatness, i-engeli engakwesokudla, njll. (2) Ukonakala kwendawo: Ukonakala okungaphezulu kwamapuleti ensimbi ikakhulukazi kufaka phakathi imifantu, izibazi, amabhamuza asicaba, ukungcola, amabhamuza, izimbotshana, isikali se-iron oxide esicindezelwe, njll. Ngenxa yezizathu zokuphepha, amapuleti ensimbi yomkhumbi wokucindezela anezidingo eziqinile ebusweni nangaphakathi.Amaphutha angenhla ngokuvamile awavunyelwe.Kodwa-ke, izindlela ezifanele zivunyelwe ukususwa, futhi indawo yokususa kufanele ibe isicaba.Ukujiya kwayo akumele kudlule umehluko ovumelekile kugqinsi lwe-steel plate.I-Interlayers nazo ngokuvamile azivunyelwe.Inkomba yokwakheka kwamakhemikhali:
①I-Carbon steel plate: ikakhulukazi thola okuqukethwe kwekhabhoni, i-silicon, i-manganese, i-phosphorus nesibabule.Amanye ama-carbon steels nawo aqukethe inani elithile lethusi, i-chromium, i-nickel, i-molybdenum, i-vanadium nezinye izakhi.Phakathi kwazo, ikhabhoni iyisici esiyinhloko sokunquma amandla epuleti lensimbi, okungukuthi, amandla epuleti yensimbi ayanda ngokunyuka kokuqukethwe kwekhabhoni.Okuqukethwe kwekhabhoni ye-carbon steel plate kuphakathi kuka-0.16 no-0.33%.I-Manganese ne-silicon nayo inomphumela wokuthuthukisa impahla nokwandisa amandla.I-silicon: 0.10–0.55%, iManganese: 0.4–1.6%.Ezinye izindinganiso azidingi i-silicon ne-manganese kumapuleti ajwayelekile okubhayela, kanti ithusi lingaphansi kuka-0.30%.Amanye amazinga afana ne-Japan ne-Russia awanazo izidingo zokuqukethwe kwethusi.Ezinye izinsimbi zekhwalithi ephezulu ziqukethe i-chromium (ngaphansi kuka-0.25%), i-nickel (ngaphansi kuka-0.30%), i-molybdenum (ngaphansi kuka-0.10%), ne-vanadium (ngaphansi kuka-0.03%).Ukwakhiwa kwamakhemikhali amapuleti ensimbi ye-boiler amamaki ahlukahlukene kuboniswa kumazinga omkhiqizo anikezwe kuThebula 6-7-3.
② I-low alloy steel plate: Ngaphezu kwezakhi zensimbi ye-carbon, kukhona nenani elithile le-molybdenum, i-chromium, i-nickel, i-vanadium, njll. Kunamazinga amaningi ensimbi ensimbi ephansi ye-alloy, phakathi kwawo izindinganiso ezivame ukusetshenziswa kakhulu. kanje: 1/2 Mo, 1/2Mo-B steel: ASTM A204, JIS G3107;Mn-1/2Mo1/2Mo, Mn-1/2Mo-V, Mn -1/2Mo-1/4Ni, Mn1/2Mo-1/2N i steel: ASTM A302, A533, JIS G3119, G3120;1Cr-1/2Mo, 11/4Cr-1/2Mo, 21/2Cr-1Mo, 3C r-1Mo, 5Cr-1/2Mo, 7Cr-1/2Mo, 9Cr-1Mo: JISG4109, ASTM A387, A533, DIN1715.
③ Ipuleti lensimbi elicishiwe neliqinile: bona i-ASTM A517, A537, A724, A734, JISG3115.
④ Insimbi yezinga lokushisa eliphansi: kufaka phakathi i-carbon steel ne-alloy steel.Ukwakheka kwamakhemikhali kanye nezakhiwo zemishini zingatholakala ku-ASTMA612, A 662, A735, A736, A738, A203, A645, JIS G3126.
⑤Insimbi engagqwali: bhekisa ku-JIS G4304, ASTM A240, AISI13, ΓOCT5632.
