Thaum lub sij hawm tsim khoom txhua hnub, vim kev laus ntawm lub qhov cub sintering, nitrogen generator, ammonia decomposition thiab lwm yam khoom siv, cov hmoov hlau metallurgy tom qab lub cub tawg muaj cov teeb meem oxidation xws li blackening, yellowing, decarburization, thiab sandblasting ntawm qhov chaw. ntawm cov khoom.
Tom qab qhov teeb meem tshwm sim, cov chaw tsim khoom yuav tsum tshawb xyuas qhov chaw tiv thaiv kom sai li sai tau.Cov khoom tshuaj ntsuam xyuas feem ntau suav nrog seb qhov kev saib xyuas ntawm lub tshuab hluav taws xob nitrogen ua haujlwm li cas, kev ua haujlwm ntawm lub tshuab hluav taws xob nitrogen, thiab seb qhov txiaj ntsig ntawm lub tshuab hluav taws xob nitrogen P860 nitrogen analyzer puas yog.Txawm hais tias qhov kev ua haujlwm siab ntawm lub tshuab hluav taws xob adsorption ntawm nitrogen generator yog qis dua tus qauv kab, seb qhov deoxygenation kub ntawm lub palladium catalyst nyob rau hauv hydrogenation thiab deoxygenation ib feem yog sab nraum qhov ib txwm muaj, seb lub nitrogen purification thiab ziab ib feem yog rhuab ib txwm, thiab cov ntsiab lus oxygen thiab nitrogen noo nyob rau tom qab kawg ntawm nitrogen purification yog cov cim Txawm hais tias nws yog nyob rau hauv qhov ntau ntawm tus qauv tus nqi, nws yog ib qho tsim nyog yuav tsum tau ua raws sijhawm rau cov teeb meem ntsig txog.
Hmoov metallurgy cov khoom feem ntau yog siv mesh siv nruam annealing rauv thiab thawb pas nrig annealing rauv rau sintering.Cov huab cua tiv thaiv tau muab faib ua cov khoom siv tooj liab thiab cov khoom siv hlau raws li cov khoom siv hmoov metallurgy.Nquag, hlau hmoov yog nias los tsim cov khoom sintered tshaj plaws, thiab hlau-raws li Cov khoom siv hlau metallurgy, high-purity nitrogen nrog cov dej ntsiab lus tsawg dua 5PPM thiab high-purity 99.999% ua los ntawm ammonia decomposition hydrogen ntau lawm ntaus ntawv los yog PSA lub tshuab hluav taws xob nitrogen hauv qhov chaw thiab hydrogenation thiab deoxygenation purification tuaj yeem siv los ua qhov chaw tiv thaiv.Tom qab qee qhov teeb meem oxidation tshwm sim hauv cov hmoov hlau metallurgy, xyuas tias lub tshuab hluav taws xob nitrogen thiab ammonia decomposition rauv yog txhua yam, lossis tom qab teeb meem ntawm lub tshuab hluav taws xob nitrogen thiab ammonia decomposition, oxidation teeb meem ntawm hmoov metallurgy cov khoom tseem muaj.
Cov kauj ruam tom ntej yuav tsum xav txog lub sintering rauv nws tus kheej.
Txawm hais tias nws yog lub qhov cub hluav taws xob lossis lub tshuab hluav taws xob mesh, yuav muaj lub tsho dej txias.Tom qab lub muffle raj ntawm lub qhov cub sintering yog hnub nyoog, yuav muaj dej to.Cov dej yuav decompose rau hauv oxygen ntawm qhov kub thiab txias, ua rau cov hmoov metallurgy cov khoom ua xim dub thiab daj thiab decarbonize.Ding Wentao, yog Hlawv ntawm qhov kub thiab txias.Cov nplaim taws yog tshwm sim los ntawm combustion ntawm hydrogen thiab hmoov metallurgical Cheebtsam nyob rau hauv lub sintering rauv.Lub sijhawm no, cov khoom siv sandblasted yuav raug tsim rau ntawm qhov chaw ntawm cov khoom, uas yog combustion residues.Yog tias siv lub npog tiv thaiv npog, nws yuav txhim kho, tab sis kev tiv thaiv siab purity nitrogen tsis nyob hauv qhov chaw yuav ua rau oxidation me ntsis.
Txawm li cas los xij, rau cov khoom lag luam ntshiab tooj liab-raws li hmoov metallurgy, tsuas yog 75% hydrogen + 25% nitrogen sib xyaw roj uas tsim los ntawm ammonia decomposition los tsim hydrogen tuaj yeem siv los ua qhov chaw tiv thaiv.Tau kawg, kev siv high-purity hydrogen yog qhov ua tau zoo dua, vim yog cov nqi roj ntau thiab kev nyab xeeb ntawm kev ua haujlwm.Feem ntau ntawm lawv siv ammonia decomposition hydrogen ntau lawm cov cuab yeej ua ib qhov chaw ntawm hydrogen.
Thaum lub muffle tube ntawm lub sintering rauv xau thiab kub hnyiab los ntawm, cov khoom ntawm lub muffle raj yuav tsum tau nres tam sim ntawd thiab hloov.Yog li tsis txhob cuam tshuam qhov zoo ntawm cov khoom!
