Pressure Boiler Steel Plate
(1) Tanthauzo: Kuwonjezera pa kufuna nyonga ndi kulimba kwinakwake, zinthuzo zimafunikiranso kukhala zofanana, ndipo zilema zovulaza zimakhala zoletsedwa kotheratu.
(2) Mtundu: Malinga ndi gulu la kamangidwe, akhoza kugawidwa m'magulu awiri: mpweya zitsulo mbale ndi aloyi mbale zitsulo;malinga ndi gulu mphamvu, akhoza kugawidwa mu mkulu, sing'anga ndi otsika kuthamanga zitsulo mbale;malinga ndi malo ogwiritsira ntchito, amatha kugawidwa m'mambale achitsulo apamwamba, apakati komanso otsika komanso osagwira zitsulo.Kuwonongeka kwa mbale yachitsulo.
(3) Zomera zazikulu zopangira ndi mayiko omwe amatulutsa kunja:
① Zomera zazikulu zopanga zapakhomo: Wugang, Anshan Iron ndi Steel, Laiwu Steel, Shanghai Iron ndi Steel, Baotou Steel, Sangang, etc.;
②Maiko akuluakulu ogulitsa kunja ndi zigawo kunja: Japan, Russia, Germany, Eastern Europe ndi mayiko ena ndi zigawo.

Makulidwe a mbale yoponderezedwa ya chotengera nthawi zambiri amachokera ku 5mm mpaka 200mm, ndipo amagawidwa m'magulu angapo makulidwe panthawiyo.Miyezo yapadziko lonse imatchula masaizi ovomerezeka a mapepala ndi zopatuka zololeka.Mawonekedwe abwino
(1) Maonekedwe a mbale yachitsulo: monga bend chikwakwa, flatness, ngodya yakumanja, etc.
(2) Zowonongeka zapamtunda: Zowonongeka zazitsulo zazitsulo zimaphatikizapo ming'alu, zipsera, thovu lophwanyika, zonyansa, tokhala, pores, zitsulo zachitsulo za oxide, etc. zolakwika zamkati.Nthawi zambiri, zolakwika zomwe tazitchulazi siziloledwa kukhalapo.Komabe, njira zoyenera zimaloledwa kuchotsedwa, ndipo malo ochotserako ayenera kukhala athyathyathya.Makulidwe ake sayenera kupitirira kusiyana kovomerezeka mu makulidwe a mbale yachitsulo.Nthawi zambiri, palibe interlayer yololedwa.Chemical composition index:
① Mpweya wachitsulo wa carbon: makamaka umazindikira zomwe zili mu carbon, silicon, manganese, phosphorous, ndi sulfure.Zitsulo zina za kaboni zimakhalanso ndi mkuwa, chromium, faifi tambala, molybdenum, vanadium ndi zinthu zina.Pakati pawo, carbon ndiye chinthu chachikulu chodziwira mphamvu ya mbale yachitsulo, ndiko kuti, mphamvu ya mbale yachitsulo imawonjezeka ndi kuwonjezeka kwa carbon.Mpweya wa carbon steel plates uli pakati pa 0.16 ndi 0.33%.Manganese ndi silicon amakhalanso ndi zotsatira zowonjezera zakuthupi ndikuwonjezera mphamvu.Silikoni: 0.10–0.55%, manganese: 0.4–1.6%.Miyezo ina ilibe zofunikira za silicon ndi manganese pama mbale wamba wowotchera, ndipo mkuwa ndi wochepera 0.30%.Miyezo ina monga Japan ndi Russia ilibe zofunikira zamkuwa.Zitsulo zina zapamwamba zimakhala ndi chromium (zosakwana 0.25%), faifi tambala (zosakwana 0.30%), molybdenum (zosakwana 0.10%), ndi vanadium (zosakwana 0.03%).Kapangidwe kake ka giredi lililonse la mbale yachitsulo chowotchera ikuwonetsedwa muzogulitsa zomwe zaperekedwa mu Gulu 6-7-3.
Nthawi zambiri maliseche kapena mitolo.Pazofunika zosalala ndi zitsulo zosapanga dzimbiri, mabokosi kapena stows kapena mabatani ziyenera kugwiritsidwa ntchito, ndipo ziyenera kukulungidwa ndi mapepala oteteza chinyezi kapena zinthu zina.
Laser telala-welched akusowekapo ndi mosalekeza variable cross-gawo gulu luso
1. Tailor Welded Blanks (Tailor Welded Blanks, TWB) amagwiritsa ntchito laser monga gwero la kutentha kwa kuwotcherera kuphatikizira ndikuwotcherera zinthu zingapo zosiyanasiyana, makulidwe osiyanasiyana, ndi zokutira zosiyanasiyana zachitsulo, chitsulo chosapanga dzimbiri, aloyi ya aluminiyamu, ndi zina zambiri mu mbale yonse.
2. Pogwiritsa ntchito ukadaulo wowotcherera wopangidwa ndi laser, ndizotheka kuphatikiza zida za makulidwe osiyanasiyana ndi milingo yamphamvu molingana ndi kupsinjika kwa magawo omangika, kukonza kusasunthika kwamapangidwe ndikuchepetsa kulemera kwa magawo, komanso kukulitsa kuchuluka kwa magwiritsidwe ntchito. wa zipangizo ndi kuchepetsa chiwerengero cha zigawo.Chiwerengero cha zigawo mu siplifies ndondomeko.Laser ogwirizana kuwotcherera luso wakhala waukulu luso njira galimoto opepuka, ndipo wakhala ntchito kwa zitsanzo za opanga ambiri.Makamaka ntchito kutsogolo ndi kumbuyo khomo mapanelo mkati, kutsogolo ndi kumbuyo longitudinal matabwa, mapanelo mbali, mapanelo pansi, A, B, ndi C nsanamira mkati mwa chitseko, gudumu chimakwirira ndi mapanelo thunthu mkati, etc.
3. Tailor Rolling Blanks (TRB), yomwe imatchedwanso kuti mbale za makulidwe osiyanasiyana, imatanthawuza kusintha kwa nthawi yeniyeni ya kukula kwa kusiyana kwa mpukutu kudzera pakompyuta panthawi yogubuduza mbale yachitsulo, kuti mbale yowondayo ikhale ndi chidziwitso chodziwikiratu. njira yozungulira yozungulira.Custom variable cross-sectional mawonekedwe.
4. Ukadaulo wopitilira muyeso wosiyanasiyana wagawo lagawo lakhala likugwiritsidwa ntchito kwambiri popanga magawo a thupi, monga chivundikiro cha injini, mzati wa B, chiwongolero chamoto, kalozera wamoto wa spacer, gulu lamkati lamkati, mudguard ndi bokosi lowonongeka, etc., ndipo wakhala bwino ntchito kwa Audi, BMW, Volkswagen, GM ndi zitsanzo zina.
5. Kuwotcherera kopangidwa ndi laser ndi ukadaulo wopitilira muyeso wa magawo osiyanasiyana amasintha makulidwe a zinthu zopondera kudzera munjira zosiyanasiyana zaukadaulo, ndipo amagwiritsidwa ntchito pothana ndi vuto la zofunikira zosiyanasiyana zonyamula katundu pazigawo zosiyanasiyana zamagalimoto onyamula katundu.Poyerekeza ndi ziwirizi, mwayi waukadaulo wopangidwa ndi laser kuwotcherera umakhala mu kusinthasintha kwake, komwe kumatha kuzindikira kuphatikizika kwa malo aliwonse ndi kuphatikizika kwazinthu zosiyanasiyana.Ubwino waukadaulo wopitilira muyeso wosiyanasiyana ndikuti palibe kuwotcherera msoko, kuuma kusinthasintha kwa mbali yautali kumakhala kofatsa, kumakhala ndi mawonekedwe abwino, komanso mawonekedwe apamwamba, kupanga bwino ndikwambiri, ndipo mtengo wake ndi otsika.Katundu, zida zamankhwala, chipolopolo cha njinga yamoto;galimoto, denga lamkati la basi, dashboard;mpando amathandizira, khomo gulu, zenera chimango, etc.
