I-Pressure Vessel Boiler Steel Plate
(1) Incazelo: Ngaphezu kokudinga amandla nokuqina okuthile, impahla nayo iyadingeka ukuze ifane, futhi amaphutha ayingozi abekwe imingcele eqinile.
(2) Uhlobo: Ngokwesigaba sokubunjwa, singahlukaniswa ngezigaba ezimbili: ipuleti yensimbi ye-carbon kanye ne-alloy steel plate; ngokwezigaba zamandla, ingahlukaniswa ngamapuleti ensimbi aphezulu, aphakathi nendawo naphansi; ngokwendawo yokusetshenziswa, ingahlukaniswa ngamapuleti ensimbi aphakeme, aphakathi nendawo naphansi kanye namapuleti ensimbi amelana. Ukugqwala kwepuleti lensimbi.
(3) Izitshalo ezinkulu ezikhiqizayo kanye namazwe akhiqiza kakhulu amazwe angaphandle:
① Izitshalo zokukhiqiza zasekhaya eziyinhloko: i-Wugang, i-Anshan Iron and Steel, i-Laiwu Steel, i-Shanghai Iron and Steel, i-Baotou Steel, i-Sangang, njll.;
②Amazwe nezifunda ezinkulu ezithumela kwamanye amazwe: Japan, Russia, Germany, Eastern Europe namanye amazwe nezifunda.

Ugqinsi lwepuleti lomkhumbi wengcindezi ngokuvamile lusukela ku-5mm luye ku-200mm, futhi luhlukaniswe ngokucaciswa okuningana kogqinsi phakathi nenkathi. Uhlu lwamazinga kazwelonke osayizi beshidi abanconyiwe kanye nokuchezuka okuvumelekile. Ikhwalithi yokubukeka
(1) Ukuma kwe-steel plate: njengokugoba isikela, flatness, i-engeli engakwesokudla, njll.
(2) Ukulimala okungaphezulu: Amaphutha angaphezulu kwepuleti lensimbi ikakhulukazi ahlanganisa imifantu, izibazi, amabhamuza acaba, ukungcola, amaqhuqhuva, izimbotshana, isikali se-iron oxide esicindezelwe, njll. Ngenxa yezidingo zokuphepha, amapuleti ensimbi yomkhumbi anezidingo eziqinile endaweni kanye amaphutha angaphakathi. Ngokuvamile, iziphambeko ezibalwe ngenhla azivunyelwe ukuba zibe khona. Kodwa-ke, izindlela ezifanele zivunyelwe ukususwa, futhi indawo yokususa kufanele ibe isicaba. Ubukhulu bayo akumele budlule umehluko ovumelekile kugqinsi lwepuleti lensimbi. Ngokuvamile, akukho interlayer evunyelwe. Inkomba yokwakheka kwamakhemikhali:
① Ipuleti lensimbi ye-Carbon: lihlonza ikakhulukazi okuqukethwe kwekhabhoni, i-silicon, i-manganese, i-phosphorus, nesibabule. Enye insimbi ye-carbon nayo iqukethe 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 ngokukhula kokuqukethwe kwekhabhoni. Okuqukethwe kwekhabhoni yamapuleti ensimbi ye-carbon kuphakathi kuka-0.16 no-0.33%. I-Manganese ne-silicon nayo inomphumela wokuthuthukisa izinto kanye nokwandisa amandla. I-silicon: 0.10–0.55%, i-manganese: 0.4–1.6%. Ezinye izindinganiso azinazo izidingo ze-silicon ne-manganese zamapuleti 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%). Ukwakheka kwamakhemikhali ebangeni ngalinye le-boiler steel plate kuboniswa kumazinga omkhiqizo anikezwe kuThebula 6-7-3.
Ngokuvamile nqunu noma izinqwaba. Ngezidingo zokushelela kanye namapuleti ensimbi engagqwali, amabhokisi noma izitofu noma abakaki kufanele kusetshenziswe, futhi kufanele ahlanganiswe nephepha elivikela umswakama noma ezinye izinto.
Ubuchwepheshe bebhodi lebhodi le-laser elithungayo elingenalutho neliqhubekayo eliguquguqukayo lesiphambano
1. I-Tailor Welded Blanks (i-Tailor Welded Blanks, i-TWB) isebenzisa i-laser njengomthombo wokushisa wokushisela ukuze ihlanganise futhi ishisele izinto ezihlukahlukene ezihlukahlukene, ugqinsi oluhlukene, nezindwangu ezihlukene zensimbi, insimbi engagqwali, ingxubevange ye-aluminium, njll. ibe yipuleti lonke.
2. Ngokusebenzisa ubuchwepheshe bokushisela obulungiselelwe nge-laser, kungenzeka ukuhlanganisa ngokunengqondo izinto zobukhulu obuhlukahlukene obuhlukahlukene kanye namazinga wamandla ngokuya ngezimo zokucindezeleka zezingxenye zesakhiwo, uthuthukise ukuqina kwesakhiwo ngenkathi unciphisa isisindo sezingxenye, futhi wandise izinga lokusebenzisa. wezinto zokwakha futhi unciphise inani lezingxenye. Inombolo yezingxenye ku-yenza inqubo ibe lula. Ubuchwepheshe bokushisela owenziwe nge-laser buye baba yindlela yobuchwepheshe eyinhloko yemoto engasindi, futhi isetshenziswe kumamodeli abakhiqizi abaningi. Ikakhulukazi esetshenziswa ngaphambili nangemuva amaphaneli angaphakathi komnyango, imishayo yobude bangaphambili nangemuva, amaphaneli aseceleni, amaphaneli aphansi, izinsika A, B, no-C ngaphakathi komnyango, amakhava amasondo namaphaneli angaphakathi esiqu, njll.
3. I-Tailor Rolling Blanks (TRB), ebizwa nangokuthi amapuleti okuqina okuhlukile, ibhekisela ekushintsheni kwesikhathi sangempela kosayizi wegebe le-roll ngekhompyutha phakathi nenqubo yokugingqika yepuleti lensimbi, ukuze ipuleti eligoqiwe elizacile libe nokunqunywa kusengaphambili. isiqondiso eduze nesiqondiso sokugoqa. Umumo wesiphambano esiguquguqukayo ngokwezifiso.
4. Ubuchwepheshe obuqhubekayo bephaneli yesiphambano esiguquguqukayo busetshenziswe kabanzi ekwenzeni izingxenye zesakhiwo somzimba, njengesembozo senjini, insika engu-B, i-chassis yomzimba, umhlahlandlela we-motor spacer, iphaneli yangaphakathi yekholomu ephakathi, i-mudguard nebhokisi lokuphahlazeka, njll., futhi isetshenziswe ngempumelelo kwa-Audi, BMW, Volkswagen, GM nezinye izinhlobo.
5. I-laser yokushisela i-laser kanye nobuchwepheshe obuguquguqukayo obuguquguqukayo obuqhubekayo bushintsha ukushuba kwezinto zokugxiviza ngezindlela ezahlukene zobuchwepheshe, futhi zisetshenziselwa ukuxazulula inkinga yezidingo ezahlukene zomthwalo othwala imithwalo yezingxenye ezahlukene zezingxenye zezimoto ezingaphansi komthwalo. Uma kuqhathaniswa nalokhu okubili, inzuzo yobuchwepheshe be-laser welding eyenziwe ngomsiki isekuguquguqukeni kwayo, okukwazi ukubona ukuhlanganisa kwanoma yisiphi isikhundla kanye nokuhlanganisa izinto ezahlukene. Inzuzo yobuchwepheshe obuguquguqukayo obuqhubekayo be-cross-section ukuthi awukho umthungo wokushisela, ukushintshwa kokuqina eduze kwesiqondiso sobude kuthambile, kunokwakheka okungcono, nekhwalithi yangaphezulu yinhle, ukusebenza kahle kokukhiqiza kuphezulu, futhi izindleko phansi. Imithwalo, imishini yezokwelapha, igobolondo lesithuthuthu; imoto, uphahla lwangaphakathi lwebhasi, ideshibhodi; ukusekelwa kwesihlalo, iphaneli yomnyango, ifreyimu yefasitela, njll.
