X7Ni9 Nickel Steel

X7Ni9 Nickel SteelIngaba iEN 10028-4ibakala1.5663, a I-9% yensimbi ye-nickelInikezelwe njengemveliso ethe tyaba ngeenjongo zoxinzelelo ezineempawu ezikhankanyiweyo ezisezantsi-zeqondo lobushushu. Kusetyenziso lobunjineli, ikhethwa apho ipleyiti kufuneka idibanise uxinzelelo -amandla esitya, ukuqina okuqinisekisiweyo kwecryogenic, kunye nokusebenza okuzinzileyo kolwakhiwo kwizixhobo ezidityanisiweyo ezinkulu. Imisebenzi eqhelekileyo ibandakanyaamaqokobhe etanki yangaphakathi yokugcina i-LNG, iinqanawa zoxinzelelo lwe-cryogenic, kunye namanye amacandelo esiqulatho esidityanisiweyo ekufuneka agcine ukuxhathisa impembelelo kubushushu benkonzo obuphantsi kakhulu. Idatha ye-EN yoluntu kunye noncwadi lomvelisi luhlala lubekaX7Ni9 / 1.5663kwiepholile kwaye enomsindoimeko kwaye uyidibanise nayoiitanki zokugcina cryogenic, {0}}iinqanawa zoxinzelelo lobushushu obuphantsi, kunye ne-LNG{0}}inkonzo enxulumeneyo.

Ixabiso lobugcisa bebakala aliveli kumxholo we-nickel kuphela. Ivela kwisiphumo esidibeneyo seikhabhoni ephantsi, malunga ne-9% Ni, ulawulo olungqongqo lokungahlambuluki, kwayeIimfuno zefuthe eliphantsi-lobushushuphantsi koxinzelelo EN-umzila wenqanawa. Kwimveliso esebenzayo, olu dibaniso lubaluleke kakhulu kwiplatework edityanisiweyo apho imathiriyeli ingadlulanga kuphela igumbi -lokujongwa amandla obushushu, kodwa kwakhona.iikhrayitheriya zempembelelo ye-cryogenicemva kokwenza kunye ne-welding. Kungako kunjaloX7Ni9 ipleyiti yentsimbiiphathwa ngokwahlukileyo kakhulu kwiintsimbi zenickel jikelele okanye ipleyiti yolwakhiwo eqhelekileyo kulwakhiwo lwenqanawa{0}}lobushushu obuphantsi.

Ukutyunjwa kwe-X7Ni9 kufuneka kufundwe kunye nendlela yayo eqhelekileyo kunye nefom yemveliso.Kwinkqubo ye-EN,X7Ni9Ingaba iukutyunjwa kweekhemikhali, 1.5663Ingaba iinombolo yezinto eziphathekayo, kwayeEN 10028-4ngumgangatho olawulayo weiimveliso ezisicaba zenziwe nge-nickel{0}}intsimbi ye-alloy ngeenjongo zoxinzelelo kunye neempawu ezichaziweyo ezisezantsi{1}}zobushushu. Uluntu EN{1}idatha ejoliswe kuyo ikwachaza1.5663 / X7Ni9njengelow -ubushushu Ni{1}}intsimbi yentsimbi yokwakhiwa kwenqanawa yoxinzelelo, ebeka ibakala ngokucacileyo kwiuxinzelelo lwecryogenic{0}}ipleyiti yenqanawaudidi endaweni ye-nickel ngokubanzi{0}iqela lentsimbi.

Ekusetyenzisweni okusebenzayo, i-X7Ni9 idla ngokuxoxwa njengepleyiti ebonelelweyo kwimeko ecinyiweyo nepholileyo.Leyo yimeko apho amandla apapashiweyo ebakala kunye-amaxabiso empembelelo yobushushu aphantsi ajongwa, kwaye ikwayindlela eyayanyaniswaIitanki zokugcina i-LNG, iinqanawa zoxinzelelo lwe-cryogenic, kunye nezinye izixhobo ezidityanisiweyo ezinkulu ezenzelwe inkonzo phantsi ukuya-196 idigri. Uncwadi lwabavelisi boluntu ngokubanziI-9% yensimbi ye-nickelintsapho idibanisa le ndlela yezinto eziphathekayoelunxwemeni ngaphezulu-kumatanki e-LNG emhlabeni, kwiitanki zamafutha, kwayeiinqanawa zothutho, kungenxa yokoX7Ni9 ipleyiti yentsimbiidla ngokuchazwa ngayoukutyunjwa, umgangatho, imeko yonikezelo, kwayeifuna ukusebenza kobushushu obuphantsi-, kungekhona ngegama lebakala kuphela.

Ipapashwe X7Ni9 ukwakheka kweekhemikhali yakhiwe ngeenxa zonke a9% uyilo lwe-nickelngekhabhoni ephantsi kunye ne-phosphorus ephantsi kakhulu kunye nesulfure. Loo chemistry yintoni enika ibakala indawo yayo kwi-uxinzelelo lobushushu obuphantsi{1}}kwisityausapho.

Khuphela: X7Ni9 iNgcaciso yoBume beMichiza

La manani achaza ukuba kutheniX7Ni9 isitya soxinzelelo lwentsimbiiphathwa njengepleyiti eyincutshe yecryogenic kunelixa elibanzi lenickel{0}}njengentsimbi. I-metallurgy ilawulwa ngokuqinileyo kwimvulophu yenkonzo ethile.

KubaX7Ni9 iimpawu zoomatshini, i EN-isiseko esijoliswe kuko aamandla okuqina ka-680–820 MPa, Amandla esivuno esincinci angama-585 MPa ukuya kuma-30 mm kunye ne-575 MPa ukusuka kwi-30 ukuya kwi-50 mm, kwayeubude obuncinane be-18%kwi+QTimeko. Lawo ngamaxabiso achaza ibakala phantsi kwendlela ye-EN yoluntu.
