Nickel chromium vs hlau chromium txhuas: Cov lus qhia xaiv lub cub tawg muaj kev lag luam
2026-04-10
Hauv cov cub tawg industrial kev xaiv, cov khoom siv ntawm hluav taws xob cua sov hlau yog ib qho tseem ceeb uas txiav txim siab ncaj qha rau cov khoom siv ua haujlwm tau zoo, lub neej ua haujlwm, thiab cov nqi ua haujlwm mus sij hawm ntev. Rau lub cub tawg ua lag luam cov neeg teb xov tooj thiab cov neeg ua haujlwm yuav khoom, kev xaiv cov hlau hluav taws xob cua sov kom raug tsis tsuas yog ua kom muaj kev tsim khoom ruaj khov xwb tab sis kuj tseem txo cov nqi kho thiab hloov pauv. Nickel-chromium alloy (NiCr), xws li cov Cr20Ni80 qib, thiab Hlau-chromium-aluminium alloy (FeCrAl), suav nrog HRE, SGHT, thiab SGHYZ, yog ob txoj kev xaiv tseem ceeb tshaj plaws hauv kev ua lag luam. Beijing Shougang Gitane, ib tus kws tshaj lij hluav taws xob cua sov hlau tus neeg muag khoom, nyob ntawm no los pab koj kom paub qhov txawv ntawm ob hom alloys no, yog li koj tuaj yeem ua qhov kev xaiv raug uas phim koj lub cub tawg ua lag luamcov xwm txheej ua haujlwm tshwj xeeb thiab cov kev xav tau ntau lawm.
Nickel-chromium alloy (NiCr) yog paub zoo txog nws cov txiaj ntsig zoo tshaj plaws, suav nrog kev ua haujlwm siab, yooj yim tsim, thiab kev tiv taus cua sov zoo heev. Nws tswj kev ua haujlwm ruaj khov los ntawm chav tsev kub txog li 1100 ℃, ua rau nws tsim nyog rau cov cub tawg kev lag luam uas xav tau kev pib-nres ntau zaus thiab muaj cov qauv nyuaj, xws li cub tawg hauv chaw kuaj mob, cub tawg kho cua sov me me, thiab cov khoom siv cua sov raug. Shougang Gitane's nickel-chromium alloy cov khoom yog ua los ntawm cov khoom siv raw khoom purity siab, thiab cov Cr20Ni80 qib hluav taws xob cua sov hlau thiab daim kab xev sawv tawm nrog kev tiv taus ruaj khov thiab kev sib txuas zoo heev. Cov yam ntxwv no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tswj qhov kub thiab txias nruab nrab thiab qis, qhov twg kev sib xws thiab kev ntseeg siab yog qhov tseem ceeb rau kev ua kom cov khoom zoo.
Nyob rau hauv kev sib piv, hlau-chromium-aluminium alloy (FeCrAl) muaj ntau qhov zoo dua nyob rau hauv qhov chaw kub siab, suav nrog kev tiv taus kub zoo heev, lub neej ntev, thiab kev siv nyiaj tsim nyog. Nws qhov kub siab tshaj plaws tuaj yeem ncav cuag txog 1420 ℃, uas siab dua li ntawm nickel-chromium alloy, ua rau nws haum rau kev ua haujlwm kub siab heev. Shougang Gitane cov khoom FeCrAl ua tau zoo, suav nrog SGHT (ua los ntawm ODS hmoov metallurgy txheej txheem), SGHYZ, thiab HRE, tsim ib txheej txhuas oxide ntom ntom rau ntawm qhov chaw thaum siv, uas ua rau lawv tiv taus oxidation thiab tiv taus creep. Yog li ntawd, lawv lub neej ua haujlwm ntev dua 3 txog 5 npaug dua li ntawm cov hlau nickel-chromium ib txwm muaj, thaum tus nqi sib tw ntau dua. Cov khoom no zoo meej rau cov cub tawg kub siab uas ua haujlwm ntawm 1000 ℃ thiab 1400 ℃, xws li cov cub tawg sintering, cov cub tawg melting, thiab cov cub tawg kho cua sov tas mus li, uas siv dav hauv ntau qhov chaw lag luam.
Yuav pab koj xaiv qhov zoo tshaj plaws, ntawm no yog cov lus qhia meej meej: yog tias koj lub cub tawg ua haujlwm ntawm qhov kub thiab txias ≤1000 ℃ thiab xav tau kev pib-nres ntau zaus, nickel-chromium alloy yog qhov kev xaiv zoo tshaj plaws; yog tias koj lub cub tawg ua haujlwm ntawm qhov kub thiab txias ≥1000 ℃ thiab xav tau kev ua haujlwm ntev, Shougang GitaneCov khoom siv FeCrAl alloy (SGHT/SGHYZ/HRE) raug pom zoo heev. Ua tus kws tshaj lij hluav taws xob cua sov alloy nrog kev paub nplua nuj, Shougang Gitane muab ntau yam khoom nickel-chromium thiab hlau-chromium-aluminium, npog los ntawm cov qib txheem mus rau cov khoom siv hmoov metallurgy ODS siab. Peb kuj muab cov khoom siv hlau thiab strip raws li koj cov kev xav tau tshwj xeeb, pab koj lub cub tawg kev lag luam ua haujlwm tau zoo thiab ruaj khov, thiab thaum kawg txo koj cov nqi tsim khoom mus sij hawm ntev.
