Yuav ua li cas smelt nickel daim hlau?
Nickel yog ib qho tseem ceeb ntawm cov hlau uas tau siv dav hauv cov roj teeb, alloys, cov ntaub ntawv tiv thaiv corrosion thiab lwm yam. Nickel phaj yog ib daim ntawv ntawm cov khoom siv nickel, feem ntau yog siv los tsim cov khoom siv tshuaj, cov khoom siv hauv nkoj, cov khoom siv hluav taws xob nuclear, thiab lwm yam. Nyob rau hauv cov txheej txheem ntawm cov nickel phaj, smelting yog qhov txuas tseem ceeb. Hauv qab no yuav qhia txog cov txheej txheem smelting ntawm nickel phaj.
Ua ntej ntawm tag nrho cov, lub smelting ntawm npib tsib xee phaj yuav tsum tau ib tug npaum li cas ntawm nickel ore li raw khoom. Nickel ore feem ntau yog los ntawm nickel ore deposits thiab muaj nickel oxides los yog sulfides. Nyob rau hauv cov txheej txheem ore hnav khaub ncaws, cov ore yuav tsum tau ua tiav rau hauv cov ntaub ntawv granular haum rau smelting los ntawm cov kauj ruam xws li crushing thiab sib tsoo.
Qhov thib ob, cov txheej txheem ore yog muab tso rau hauv lub qhov cub smelting rau smelting. Lub qhov cub smelting feem ntau yog siv lub qhov cub kub kub, xws li lub qhov cub hluav taws xob, lub tshuab hluav taws xob, lub tshuab hluav taws xob, thiab lwm yam. Thaum lub sij hawm smelting, ib qho tsim nyog tus nqi ntawm kev txo tus neeg sawv cev, xws li coke lossis charcoal, thiab flux, xws li limestone los yog hornblende, yuav tsum tau ntxiv los txhawb qhov txo thiab melting ntawm npib tsib xee. Nyob rau tib lub sijhawm, cov khoom molten yuav tsum tsis tu ncua stirred thaum lub sij hawm smelting txheej txheem kom qhov kub thiab txias tusyees faib kom impurities xws li manganese thiab hlau nyob rau hauv cov nickel ore yuav txo tau thiab infiltrated.
Tom qab ntawd, cov khoom siv nickel molten tso tawm los ntawm lub qhov cub smelting yog sai condensed los ua granular nickel ingots. Thaum lub sij hawm condensation txheej txheem, dej txias los yog roj cua txias yuav siv tau los ua kom cov khoom molten sai sai solidify rau granular nickel ingots.
Thaum kawg, cov condensed nickel ingots yog refined thiab tsim. Nickel ingots feem ntau muaj qee yam impurities thiab yuav tsum tau ua kom zoo dua los txhim kho qhov purity thiab zoo ntawm npib tsib xee. Cov txheej txheem refining feem ntau muaj xws li tshuaj tua kab mob, electrolysis los yog lub tshuab nqus tsev distillation kom tshem tawm impurities thiab txhim kho cov purity ntawm npib tsib xee. Nyob rau tib lub sijhawm, nickel ingots kuj yuav tsum tau tsim raws li cov neeg siv khoom xav tau, xws li kev ua cov phaj, tuav thiab lwm yam duab, thiab kev kho deg kom tau raws li kev xav tau ntawm kev lag luam.
Feem ntau, cov txheej txheem smelting ntawm npib tsib xee phaj yuav tsum mus los ntawm raw khoom npaj, smelting, condensation thiab refining, thiab thaum kawg tau txais ib tug tsim nickel phaj khoom. Cov txheej txheem no yuav tsum muaj cov khoom siv kub thiab kub siab thiab kev txhawb nqa kev lag luam, thiab nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj qhov kub thiab txias, qhov sib piv ntawm cov khoom siv thiab nplawm tsis tau nyob rau hauv cov txheej txheem smelting kom paub tseeb tias qhov zoo thiab kev ua tau zoo ntawm cov nickel phaj.
