QN1803 (304D) mbale yachitsulo chosapanga dzimbiri
1. Kufotokozera:
Gulu lazogulitsa zatsopano QN1803 ndiye mtundu woyamba wa nayitrogeni wokwera kwambiri padziko lonse lapansi, kukana dzimbiri, kupulumutsa faifi wachitsulo chosapanga dzimbiri.
Pamaziko owonetsetsa kuti kukana kwa dzimbiri kofanana ndi 304 chitsulo chosapanga dzimbiri, mphamvu ya zinthuzo imayenda bwino, komanso zinthuzo.
mtengo umachepetsedwa, zomwe zimapangitsa kuti zikhale zotsika mtengo komanso zopikisana pamsika kuposa 304 zitsulo zosapanga dzimbiri.
Zatsopano zopangidwa ndi kapangidwe kazinthu: nayitrogeni wambiri (≥2000ppm), chromium yapamwamba (≥18%), faifi tambala (~ 3.0%) ndi mkuwa wambiri (≥1.5%).
Kudzera papulatifomu ya digito ya R&D ya Thermo-Calc thermodynamic phase calculation software ndi kusanthula deta yoyesera, kusintha
alloying zinthu za gawo lililonse gawo osati bwino dzimbiri kukana kwa mankhwala, komanso amapanga mphamvu zokolola za QN1803
kuposa 1.3 kuposa 304.
QN1803 ili ndi izi:
1) chiwombankhanga chofanana ndi PREN=Cr+3.3Mo+30N-Mn chili pamwamba pa 19.0, chomwe chili ndi mphamvu yofanana ndi 304.
chitsulo chosapanga dzimbiri.
2) kukana dzimbiri yunifolomu mu dilute hydrochloric acid, kusungunula sulfuric acid, acetic acid + mchere ndi malo ena ndizabwinoko kuposa
304 chitsulo chosapanga dzimbiri.
3) kukana kwa dzimbiri ndikwabwino kuposa 304 komwe kumagwiritsidwa ntchito kwenikweni mutapinda, kupondaponda, kulimba komanso kuzizira kwina.
4) mphamvu zokolola ndizoposa 1.3 nthawi za 304 zitsulo zosapanga dzimbiri, ndipo zimakhala ndi elongation ya osachepera 45%. Valani kukana ndi
kutopa ndikwabwino kuposa 304 chitsulo chosapanga dzimbiri.
5) ntchito yabwino kuwotcherera, mphamvu pambuyo kuwotcherera ndi apamwamba kuposa 304 zitsulo zosapanga dzimbiri, ndi kukana dzimbiri ndi
kuyerekeza ndi 304 zitsulo zosapanga dzimbiri.
