Thaum Lub Peb Hlis 12, lub ntiaj teb txoj kab uas hla loj tshaj plaws thiab hnyav tshaj plaws weldless stainless hlau nplhaib forging ua los ntawm 316H high-purity stainless hlau tau ua tiav tiav.Nws yuav raug siv los tsim kuv lub teb chaws thawj plaub tiam nuclear fais fab unit-Fujian Xiapu 600,000 kilowatt ceev Cov tub ntxhais tivthaiv txhawb lub nplhaib ntawm neutron reactor (tom qab no hu ua lub reactor ceev) ua qauv qhia reactor.Raws li tsuas yog stainless hlau khoom chaw tsim tshuaj paus nyob rau hauv Suav teb uas muaj peev xwm ua tau raws li tag nrho cov kev cai ntawm cov txheej txheem no,TISCOtau ua tiav tag nrho cov hauj lwm ntawm guaranteeing mov.
Lub reactor ceev ceev yog lub kauj ruam thib ob hauv "peb-kauj ruam" txoj hauv kev ntawm kuv lub teb chaws txoj kev txhim kho hluav taws xob nuclear "thermal reactor-fast reactor-fusion reactor".Nws yog hom reactor uas nyiam tshaj plaws ntawm lub ntiaj teb thib plaub tiam siab heev nuclear zog system thiab tuaj yeem ua rau kom muaj peev xwm siv cov roj nuclear ntau.Raws li "tus txha caj qaum" ntawm tag nrho cov thawv ntim, lub loj loj annular forging muaj txoj kab uas hla ntawm 15.6 meters thiab qhov hnyav ntawm 150 tons.Nws yuav tsum tiv taus qhov hnyav ntawm 7000 tons hauv cov qauv, tiv taus qhov kub thiab txias ntawm 650 degrees, thiab khiav tsis tu ncua rau 40 xyoo.Yav dhau los, xws li forgings loj heev hauv tsev thiab txawv teb chaws tau tsim los ntawm ntau ntu billet pawg vuam, thiab cov khoom siv thiab kev ua tau zoo ntawm cov vuam seam tsis muaj zog, uas tau muab zais zais kev nyab xeeb rau kev ua haujlwm ntawm nuclear fais fab nroj tsuag.Lub koom haum ntawm Hlau ntawm Suav Academy ntawm Sciences pioneered tus txheej txheem ntawm "ua loj ntawm me", siv 58 high-purity 316H stainless hlau nruam casting slabs rau superimpose thiab forge lub 100-tuj-theem thawj billet yuav tsum tau ua lub nplhaib. , uas daws cov tsoos "ua kom loj nrog loj" txheej txheem ntawm kev thauj khoom steel ingots.Metallurgical defects muaj nyob rau hauv cov txheej txheem solidification.
Cov xwm txheej hnyav ntawm kev siv thiab cov cuab yeej ua lag luam tshiab ua rau muaj teeb meem tsis tau pom dua rau cov tshuaj lom neeg muaj pes tsawg leeg thiab sib xws ntawm qhov yuav tsum tau ua ntu nruam casting slab.TISCOthiab Suav Academy ntawm Atomic Energy thiab lub koom haum ntawm Kev Tshawb Fawb Hlau ntawm Suav Academy ntawm Kev Tshawb Fawb tau sib koom ua ke tshawb fawb thiab tsim los txhawb kev sim thiab tsim cov kev tshawb fawb no mus rau qhov tseem ceeb tshaj plaws ntawm lub tuam txhab.Kev kub siab ua haujlwm, corrosion tsis kam, steel purity, lub koom haum sab hauv uniformity, qhov tseeb qhov tseeb thiab lwm yam ntsuas tau mus txog qib tshiab.Peb tau mastered lub manufacturing technology ntawm 316H stainless hlau daim hlau, nruam casting billets, electroslag ingots thiab lwm yam khoom rau cov khoom tseem ceeb ntawm ceev reactors.Thiab muaj peev xwm ntau lawm, uas txhawb nqa txoj kev vam meej ntawm "lub ntiaj teb zoo tshaj plaws".
