I-Liquefied Natural Gas (LNG), ingxenye yayo eyinhloko i-methane, "iphethiloli eluhlaza" esezingeni eliphezulu, ehlanzekile, esebenza kahle futhi elula, ethathwa njengamandla ezinsalela ahlanzekile emhlabeni futhi ingenye yemithombo yamandla ebaluleke kakhulu ye-21st. ikhulu leminyaka.
Insimbi engu-9% ye-nickel iwuhlobo lwensimbi ecishiwe enekhabhoni ephansi futhi ethambile, equkethe i-nickel element engu-9%, nokushisela kwayo okuhle kakhulu, izindleko eziphansi, amandla aphezulu kanye nokuqina okuhle kakhulu kwe--196 °C ultra-low ultra-low nezinye izinzuzo sekuye kwaba okuyinhloko. amandla ekwakhiweni kwamathangi amakhulu okugcina i-LNG. Sizibophezele ekukhiqizeni izinto ezisetshenziswayo zokushisela ezisezingeni eliphezulu futhi sihlinzeke ngezinto ezisetshenziswayo zokushisela kanye nezixazululo zokushisela izinto ezisetshenziswayo zokushisela insimbi ye-nickel engu-9% njengomphakeli wekhwalithi ephezulu.
"Race the deer" - yini eyenza izinto zethu zokushisela zigqame
Ngaphansi kwengcindezi ekabili yezindaba zamandla omhlaba kanye nezemvelo, imboni ye-LNG ekhaya naphesheya iyaqhubeka nokukhuphuka. Izimo zokugcina izinga lokushisa eliphansi kakhulu le-LNG ziyinselele enzima yezinto zokusingatha kanye nezinto ezisetshenziswayo zokushisela. Isikhathi eside, u-9% wezinto ezisetshenziswayo zokushisela ze-nickel steel ziye zaphathwa yizinto ezisetshenziswayo zokushisela ezivela kwamanye amazwe. Ukuze sinqamule ukuvinjelwa kobuchwepheshe bangaphandle futhi sihlangabezane nezidingo zemboni ye-LNG, sihole ekuhlinzekeni ngensimbi ephelele ye-nickel engu-9% ehambisana nenqubo yokushisela kanye nenqubo yokushisela, futhi sagqama esixukwini ngekhwalithi yomkhiqizo enhle kakhulu, ithimba lochwepheshe. kanye nenkonzo ezinikele necabangelayo.
Kuthuthukiswa uhla oluphelele lwezinto ezisetshenziswayo zokushisela kanye nezinqubo zokushisela
Ukupheka nxazonke ngokwesidingo semakethe
Siklame futhi sathuthukisa uhla olugcwele lwekhwalithi ephezulu, i-9% yensimbi ye-nickel ehambisanayo kanye nezinqubo zokushisela, okuhlanganisa ama-electrode, izintambo ze-arc ezingaphansi kwamanzi nezinhlanganisela ze-flux, izintambo ezinama-flux-cored zokushisela ezihlala ngokugcwele, nezintambo zokushisela ze-argon arc. Lolu chungechunge lwemikhiqizo lunokushisela okuhle kakhulu kanye nezakhiwo zemishini, futhi imiphumela yokuhlolwa kwe-CTOD ne-drop weight mihle kakhulu, imininingwane ethile yomkhiqizo ikhonjisiwe kuthebula elingezansi.
Uhla olugcwele lwemininingwane ye-nickel steel welding consumables engu-9%.

"Kokubili kanzima futhi okuthambile" - ikhwalithi eqinile, isevisi enomdlandla
Izinto ezisetshenziswayo zokushisela zenkampani yethu ziye zamelana nokuhlolwa kwemakethe ngekhwalithi enhle kakhulu esebenzisekayo yokushisela, futhi zingabokuqala ukuthola ubuchwepheshe obusebenzisekayo bokushisela obunelungelo lobunikazi bensimbi ye-nickel engu-9% eChina. Sisekelwa i-R&D eqinile, ithimba lezobuchwepheshe nesevisi, sisiza amakhasimende ukuthi athole isisombululo sensimbi ye-nickel esingu-9%.
Ilungelo lobunikazi lokusungula nokusebenzisa impendulo
"Ukuhola imboni, iqhakaza yonke indawo" - ukufakazela amandla ngokusebenza
Besikhuthaza ukwenziwa kwasendaweni kwezinto ezisetshenziswayo zokushisela amathangi okugcina e-nickel-steel LNG angu-9%. Kusukela ngo-2016, izinto ezisetshenziswayo ze-Jingqun ze-nickel steel welding ezingu-9% zisetshenziswe ngempumelelo emathangini olwandle e-LNG futhi bathola imiphumela eminingi emangalisayo. Kamuva, yavela kumaphrojekthi amabili wethangi lomhlaba we-50,000 cubic meter bimetallic LNG e-Changchun ngo-2021, futhi yakhuthazwa ngokulandelana futhi yasetshenziswa kuphrojekthi yethangi lomhlaba le-LNG engu-200,000 cubic meter enkulu.
Isizinda sephrojekthi ye-nickel steel LNG sethangi lasolwandle esingu-9%.
