Musi waKurume 12, dhayamita hukuru pasi rose uye inorema kwazvo yesimbi isina simbi inogadzirwa ne 316H high-purity stainless simbi yakabudirira kugadzirwa.Ichashandiswa kugadzira nyika yangu yekutanga yechizvarwa chechina nyukireya unit-Fujian Xiapu 600,000 kilowatt nekukurumidza Iyo yepakati chikamu chekutsigira mhete yeneutron reactor (inozonzi inokurumidza reactor) kuratidzira reactor.Seye chete simbi isina simbi inogadzira zvinhu muChina iyo inogona kuzadzisa zvese zvehunyanzvi zvinodiwa pakuita uku,TISCOapedza zvinobudirira mabasa ese ekuvimbisa kuwanikwa.
Inokurumidza reactor inhanho yechipiri mu "nhanho-nhatu" nzira yekusimudzira simba renyukireya renyika yangu "thermal reactor-fast reactor-fusion reactor".Ndirwo rudzi rwechina chizvarwa chechina chepamusoro chesimba renyukireya uye rinogona kuwedzera zvakanyanya mashandisirwo emafuta enyukireya.Se "musana" weiyo yese stack mudziyo, hofori annular forging ine dhayamita 15.6 metres uye huremu hwematani zana nemakumi mashanu.Inodiwa kutsungirira huremu hwe7000 matani muchimiro, kushingirira tembiricha yakakwira ye650 madhigirii, uye ichimhanya ichienderera kwemakore makumi mana.Munguva yakapfuura, hofori dzakakura dzakadaro kumba nekune dzimwe nyika dzakagadzirwa ne-multi-segment billet group welding, uye chimiro chezvinhu uye kushanda kweiyo weld seam yakanga isina simba, iyo yakaisa njodzi yakavanzwa yekushanda kwemagetsi enyukireya.Sangano reMetals reChinese Academy of Sciences rakapayona nzira ye "kugadzira hukuru kubva kudiki", ichishandisa 58 high-purity 316H simbi isina tsvina inoenderera mberi ichikanda slabs kuti iwedzere uye kugadzira 100-ton-level yepakutanga billet inodiwa kugadzira mhete. , iyo yakagadzirisa tsika dzechinyakare "kuita hombe nehombe" nzira yekurodha ingots dzesimbi.Metallurgical defects inowanikwa mukusimbisa maitiro.
Mamiriro ezvinhu akaomarara ekushandiswa uye mhando-nyowani yekugadzirisa tekinoroji inoisa zvipingamupinyi zvisati zvamboitika kune kuumbwa kwemakemikari uye kufanana kweinodiwa inoenderera mberi yekukanda slab.TISCOuye Chinese Academy of Atomic Energy neInstitute of Metal Research yeChinese Academy of Sciences vakabatana vakatsvakurudza uye vakagadzira kusimudza kuedza nekugadzira tsvakurudzo iyi kune inonyanya kukosha yekambani.High tembiricha kuramba, corrosion kuramba, kuchena kwesimbi, yemukati sangano kufanana, dimensional kurongeka uye zvimwe zviratidzo zvasvika padanho idzva.Isu takaziva tekinoroji yekugadzira ye316H mahwendefa esimbi asina tsvina, anoenderera achikanda mabheti, electroslag ingots uye zvimwe zvigadzirwa zvemichina yakakosha yeanokurumidza reactor.Uye ine huwandu hwekugadzira huwandu, iyo inotsigira zvakasimba budiriro yakabudirira yeiyi "yakanakisa pasirese".
