Yuav ua li cas yaj molybdenum raj?
Molybdenum yog ib qho tseem ceeb ntawm cov hlau nrog ntau yam kev siv. Nws yog tsuas yog siv los tsim cov alloys, khoom siv hluav taws xob, petrochemicals, thiab lwm yam. Yuav kom yaj molybdenum hlab, yuav tsum tau ua ntau cov kauj ruam thiab cov txheej txheem kom tiav. Cov hauv qab no yog cov txheej txheem smelting ntawm molybdenum raj:
1. Kev npaj cov khoom siv raw: Ua ntej, koj yuav tsum npaj cov khoom zoo molybdenum ore ua raw khoom, feem ntau yog siv molybdenum oxide, molybdenum-lead ore, molybdenum-tooj liab ore, thiab lwm hom ore. Cov ores no yuav tsum tau ua tiav los ntawm kev sib tsoo, sib tsoo, thiab lwm yam txheej txheem kom tau cov hmoov ore nrog qhov loj me me.
2. Leaching extraction: Muab cov hmoov ore rau hauv cov kua qaub rau leaching extraction, feem ntau yog siv cov kua qaub xws li sulfuric acid los yog hydrofluoric acid rau leaching. Nyob rau hauv txoj kev no, molybdenum keeb tuaj yeem muab rho tawm los ntawm cov ore los tsim cov tshuaj molybdenum.
3. Kev sib cais los ntawm nag lossis daus: Los ntawm kev ntxiv cov tshuaj tua kab mob, impurities thiab lwm yam hlau nyob rau hauv cov tshuaj molybdenum uas muaj cov tshuaj sib cais kom tau txais cov tshuaj molybdenum leaching tov nrog ntau dua purity.
4. Oxidation thiab txo qis: Cov tshuaj molybdenum leaching tau raug rau oxidation-txo cov tshuaj tiv thaiv los hloov lwm yam hlau thiab impurity oxides nyob rau hauv cov khoom precipitates, uas ces lim thiab sib cais kom tau molybdenum-muaj hmoov.
5. Smelting rau hauv ingots: Cov hmoov uas tau txais molybdenum yog muab tso rau hauv ib lub qhov cub smelting, thiab ib tug tsim nyog tus nqi ntawm txo tus neeg sawv cev thiab melting agent. Nws yog melted los ntawm high-kub cua sov los hloov nws mus rau hauv molybdenum ingot.
6. Moulding: Lub molybdenum ingot yog rhuab thiab yaj dua, thiab tom qab ntawd molded rau hauv cov khoom tubular los ntawm pwm thiab kev ua haujlwm siab.
7. Kev soj ntsuam zoo: Cov molded molybdenum raj yuav raug soj ntsuam nruj, nrog rau kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg, kuaj cov cuab yeej ntawm lub cev, thiab lwm yam, kom ntseeg tau tias cov khoom ua tau raws li tus qauv yuav tsum tau ua.
Nyob rau hauv cov ntsiab lus, cov txheej txheem ntawm smelting molybdenum hlab yog ib tug complex txheej txheem, uas yuav tsum tau ntau yam xws li raw khoom npaj, leaching extraction, nag lossis daus sib cais, oxidation-txo, smelting rau hauv ingots, molding, thiab kev soj ntsuam zoo. Tsuas yog ua raws li cov txheej txheem nruj me ntsis tuaj yeem tsim cov khoom tsim nyog molybdenum raj.
