Background Technology ntawm vanadium nitrogen
Vanadium tuaj yeem ua kom lub zog, plasticity thiab toughness ntawm steel thiab yog ib qho tseem ceeb microalloying keeb nyob rau hauv steel. Ntau tshaj 90% ntawm Tuam Tshoj cov khoom lag luam vanadium yog vanadium alloys, uas yog ntxiv rau cov hlau hauv daim ntawv ntawm cov hlau xws li ferrovanadium, vanadium carbide thiab vanadium carbonitride. Thaum ntxiv rau cov hlau hauv daim ntawv ntawm vanadium-nitrogen alloy, nws tuaj yeem muaj cov txiaj ntsig ntawm kev nce vanadium thiab nitrogen rau cov hlau tib lub sijhawm. Vim hais tias cov ntsiab lus vanadium ntawm vanadium nitrogen alloy xav tau rau cov hlau alloy kom ua tiav tib lub zog me dua li cov ntsiab lus vanadium ntawm ferrovanadium, yog li ntawd, piv nrog ferrovanadium, vanadium nitrogen alloy txuag vanadium cov peev txheej thiab txo cov nqi tsim khoom, thiab tau txais txiaj ntsig zoo. los ntawm hlau thiab steel smelting tuam txhab.
Tam sim no, muaj ntau txoj kev npaj rau vanadium nitrogen alloys, tab sis ntau yam ntawm lawv tej zaum yuav tsis tsim nyog nyob rau hauv kev xaiv thiab xav txog cov txheej txheem txheej txheem thiab tej yam kev mob tsis, thiab feem ntau muaj teeb meem xws li tus nqi siab, tsawg nitrogen cov ntsiab lus ntawm cov khoom, thiab loj fluctuations nyob rau hauv muaj pes tsawg leeg. Yog li ntawd, kev tshawb fawb txog kev ua haujlwm zoo, kev ua haujlwm siab thiab kev lag luam yog ib lub ntsiab lus uas feem ntau ntawm cov neeg tsim khoom tau tshawb nrhiav.
Kev siv cov ntsiab lus ntawm vanadium nitrogen
Lub hom phiaj ntawm qhov kev tsim khoom tam sim no yog muab cov vanadium nitrogen alloy thiab nws txoj kev tsim khoom rau qhov tsis xws luag ntawm cov duab ua ntej, thiab txhim kho qhov zoo ntawm vanadium nitrogen alloy los ntawm kev txhim kho cov txheej txheem, kho thiab optimizing cov xwm txheej tsis zoo, thiaj li. daws cov teeb meem ntawm cov ntsiab lus nitrogen tsawg ntawm cov khoom, kev hloov pauv loj ntawm cov khoom sib xyaw, thiab txhim kho qhov zoo ntawm vanadium nitrogen alloy.
Tshwj xeeb, ib txoj kev tsim khoom ntawm vanadium-nitrogen alloy ntawm tam sim no invention muaj xws li:
(1) Sib tov vanadium tebchaw, txo cov neeg sawv cev, khi thiab hlau hmoov sib npaug raws li qhov sib piv, nias thiab qhuav kom tau cov khoom molding;
(2) cov khoom siv molding yog muab tso rau hauv lub cub hluav taws xob thiab mus rau theem preheating, carbonization theem thiab nitriding theem sequentially, nyob rau hauv qhov kub ntawm lub carbonization theem > kub ntawm nitriding theem > kub ntawm lub preheating theem;
(3) Txias, rauv kom tau txais vanadium nitrogen alloy.
