Ingxubevange ye-Nickel Esebenza Kakhulu: Ingxubevange engu-690

Zitholele ukuqina nokuthembeka okukhethekile kwe-Alloy 690, ingxubevange ye-nickel-chromium ye-premium eyakhelwe izinhlelo zokusebenza ezisezingeni eliphezulu. Idume ngokumelana nokugqwala okuphakeme, i-Alloy 690 idlula zonke ezindaweni ezinolaka njengokucubungula amakhemikhali, ukukhiqiza amandla enuzi, kanye nezicelo zasolwandle. Ngokumelana kwayo okukhethekile nokuqhekeka kokugqwala kwengcindezi, ukugqwala, nokugqwala kwe-crevice, i-Alloy 690 iqinisekisa ukusebenza kwesikhathi eside nobuqotho ngisho nasezimeni ezinzima kakhulu. Idizayinelwe izinhlelo zokusebenza ezibucayi lapho ukuthembeka kubaluleke kakhulu, i-Alloy 690 iletha ukusebenza okungenakuqhathaniswa, okuyenza ibe ukukhetha okuphezulu ezimbonini ezifunayo emhlabeni jikelele. Izwa ukuthula kwengqondo nokuqina okungenakuqhathaniswa nge-Alloy 690 yamaphrojekthi akho ayinselele kakhulu.

Isici somkhiqizo

I-alloy 690 inokumelana okuhle kakhulu nokugqwala kwe-intergranular kanye ne-intergranular stress corrosion cracking, ikakhulukazi esetshenziswa kumshini wokuphehla amandla enuzi wesitshalo se-steam generator. I-pressurized water reactor nuclear power plant steam generator ithubhu yokudlulisa ukushisa idlule inqubo yokuthuthukiswa, okuhlanganisa i-304 austenitic stainless steel, 600 alloy, 800 alloy kanye ne-690 alloy. Ucwaningo lokwehluleka ukugqwala kwe-alloy engu-600 enkonzweni lubonisa ukuthi ukugqwala kwe-intergranular kanye nokuqhekeka kokugqwala kwe-intergranular yizinkinga ezinkulu. 690 ingxubevange, njengempahla yamashubhu okudlulisa ukushisa kwamajeneretha omusi ezitshalweni zamandla enuzi ezicindezelwayo zamanzi, ayikatholakali iphukile kusukela yaqala ukusetshenziswa ngawo-1990s.

Isicelo somkhiqizo

I-alloy 690 isetshenziswa kakhulu njengempahla yeshubhu yokudlulisa ukushisa kumajeneretha omusi ezitshalweni zamandla enuzi ezicindezelwayo zamanzi, okuyi-

Ubuchwepheshe obuyinhloko be-steam generator. Njengamanje, i-China ibisebenzisa amayunithi esitshalo samandla enuzi acindezelwe amanzi, i-Qinshan I kuphela esebenzise i-800 alloy, Qinshan II, Dada.

amayunithi ezitshalo zamandla asebenza e-China, isigaba sokuqala kuphela se-Qinshan esasebenzisa i-alloy engu-800, i-Qinshan II, i-Daya Bay kanye ne-Lingao yamandla enuzi asebenzisa i-690 alloy njengento yokudlulisa ukushisa kwe-steam generator.

I-Qinshan II, i-Daya Bay kanye nesikhungo samandla enuzi sase-Ling'ao zisebenzisa ingxubevange engu-690 njengethubhu le-steam generator yokudlulisa ukushisa.

Iningi lezitshalo zamandla enuzi ezicindezelwayo zamanzi ezakhiwayo futhi ezihlelwayo zisebenzisa ingxubevange engu-690 njengesisetshenziswa seshubhu le-steam generator.

Iningi lezitshalo zamandla enuzi ezicindezelwayo zamanzi ezakhiwayo nezihlelwayo nazo zisebenzisa ingxubevange engu-690 njengethubhu le-steam generator yokudlulisa ukushisa.
