Khoom Description
Vanadium-nitrogen alloy yog cov khoom siv ntxiv ntawm vanadium thiab nitrogen, feem ntau yog siv los tsim cov hlau microalloyed. Vanadium-nitrogen alloy tuaj yeem txhim kho cov cuab yeej zoo ntawm cov hlau xws li lub zog, toughness, ductility thiab thermal qaug zog tsis kam, thiab ua rau cov hlau muaj qhov zoo weldability. Kev tsim cov vanadium-nitrogen alloy tsuas yog siv cov khoom siv raw xws li vanadium pentoxide, carbon hmoov, thiab cov neeg ua haujlwm nquag. Nyob rau hauv kev tiv thaiv ntawm ib txwm muaj siab thiab nitrogen cua, cov dawb paug ua los ntawm raw cov ntaub ntawv yog muab tso rau hauv ib tug high-kub qhov cub, thiab tom qab ib tug high-kub tshuaj tiv thaiv, ib tug vanadium-nitrogen alloy yog generated. Cov cuab yeej tseem ceeb rau kev tsim cov vanadium-nitrogen alloy yog qhov chaw nruam thawb phaj siab-kub rauv.
Kev ua kom muaj zog thiab ua kom zoo dua cov nplej muaj txiaj ntsig zoo dua: Piv nrog ferrovanadium, vanadium-nitrogen alloys tuaj yeem ntxiv dag zog thiab ua kom cov nplej zoo dua, yog li txhim kho kev ua haujlwm ntawm cov hlau. Nyob rau hauv tib lub zog, ntxiv vanadium-nitrogen alloy tuaj yeem txuag tau 30% mus rau 40% ntawm vanadium ntxiv, uas yuav pab txo cov nqi ntawm steelmaking. Vanadium-nitrogen alloy tuaj yeem txhim kho cov khoom zoo ntawm cov hlau xws li lub zog, toughness, ductility thiab thermal qaug zog. Vanadium-nitrogen alloys yog siv dav hauv kev tsim cov qauv hlau, cov cuab yeej steel, yeeb nkab steel, steel tuav, cam khwb cia hlau thiab lwm yam ntaub ntawv hlau. Tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov high-strength low-alloy steel, daim ntawv thov cov nyhuv ntawm vanadium-nitrogen alloys yog tshwj xeeb yog tseem ceeb.
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam steel, qhov kev thov rau cov hlau ua haujlwm siab tau nce ntxiv. Raws li ib qho tseem ceeb alloy additive, kev lag luam thov rau vanadium-nitrogen alloy tseem loj hlob. Kev tsim tshuab ntawm vanadium-nitrogen alloy yog txhim kho tas li, thiab ntau lub tuam txhab hauv tsev thiab txawv teb chaws muaj peev xwm tsim tau nws tus kheej. Tuam Tshoj Panzhihua Hlau thiab Hlau Group yog ib qho ntawm cov tuam txhab ua lag luam hauv vanadium-nitrogen alloy. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tshawb fawb thiab kev tsim cov ntaub ntawv tshiab, vanadium-nitrogen alloy yuav tsum tau siv rau hauv ntau lub teb, thiab kev lag luam kev cia siab yog dav.
Tuam Tshoj tau tsim lub teb chaws cov qauv rau vanadium-nitrogen alloys (xws li GB / T 20567-2020), uas teev cov kev cai, xeem txoj kev, tshuaj xyuas, ntim, cim, cia thiab zoo daim ntawv pov thawj ntawm vanadium-nitrogen alloys. Kev tsom xam ntawm cov ntsiab lus nitrogen hauv vanadium-nitrogen alloys yog qhov tseem ceeb tshwj xeeb. Cov txheej txheem ib txwm siv tshuaj distillation, tab sis cov thev naus laus zis niaj hnub xws li TC600 oxygen thiab nitrogen analyzer kuj tau siv los ntsuas cov ntsiab lus nitrogen sai thiab raug. Nyob rau hauv cov ntsiab lus, vanadium-nitrogen alloy yog ib hom tshiab ntawm alloy additive nrog kev ua tau zoo heev thiab daim ntawv thov kev cia siab, ua lub luag haujlwm tseem ceeb hauv kev lag luam steel thiab lwm yam kev lag luam.
