Cov txheej txheem smelting ntawm Zhenan nickel hlau
Lub smelting ntawmnickel xovyog hais txog cov txheej txheem ntawm cua sov cov nickel hlau saum nws cov ntsiab lus melting kom yaj nws mus rau hauv lub xeev ua kua. Nickel yog cov khoom siv hlau nrog cov nqi siv tseem ceeb, thiab nws cov txheej txheem smelting tseem ceeb heev. Txoj kev smelting ntawm nickel hlau yuav qhia hauv qab no.
Ua ntej, kev npaj. Ua ntej smelting nickel hlau, koj yuav tsum tau npaj cov khoom siv thiab cov khoom siv raw. Ua ntej, npaj cov nickel hlau thiab smelting cov cuab yeej, xws li furnaces, crucibles, melting point meters, thiab lwm yam. Secondly, npaj flux thiab tiv thaiv roj. Cov flux tuaj yeem pab tshem tawm cov oxide nyob rau saum npoo ntawm cov nickel hlau, thiab cov roj tiv thaiv tuaj yeem tiv thaiv cov nickel hlau los ntawm oxidation zoo. Thaum kawg, xyuam xim rau kev nyab xeeb. Nco ntsoov ua txoj haujlwm zoo ntawm kev tiv thaiv thaum ua haujlwm kom tsis txhob muaj xwm txheej.
Thib ob, kev ua haujlwm melting. Muab cov nickel xaim npaj rau hauv lub crucible, thiab tom qab ntawd maj mam nce qhov kub thiab txias raws li lub melting point ntawm npib tsib xee xaim kom txog thaum cov nickel hlau yog melted tag nrho rau hauv lub xeev cov kua. Nyob rau hauv cov txheej txheem no, nws yog ib qho tsim nyog yuav tsum ua kom lub qhov cub kub kom ruaj khov thiab tswj cov smelting ceev kom tsis txhob overheating los yog tsis zoo kub tswj, uas yuav ua rau muaj kev hloov nyob rau hauv cov muaj pes tsawg leeg ntawm cov nickel hlau los yog oxidation.
Tom qab ntawd, tshem tawm impurities. Thaum cov hlau nickel melted rau hauv cov kua, cov oxide thiab lwm yam impurities nyob rau saum npoo ntawm nickel hlau yuav raug tshem tawm los ntawm kev ntxiv flux. Cov flux yuav hnov mob nrog cov oxide, ua rau cov oxide yaj rau ntawm cov nickel hlau, thiab ces muab tshem tawm ntawm lub crucible nrog rau cov kua nickel hlau. Cov txheej txheem no yuav tsum tau xaiv thiab ntxiv cov flux kom tsis txhob muaj kev cuam tshuam ntawm cov flux ntau dhau, nrog rau kev tswj xyuas lub sijhawm thiab qhov kub thiab txias kom ntseeg tau qhov zoo ntawm cov nickel hlau.
Thaum kawg, txias thiab solidify. Thaum cov nickel hlau yog melted thiab lub impurity tshem tawm cov hauj lwm tiav, cov nickel hlau yuav tsum tau txias rau chav tsev kub thiab ces cov khoom nickel yog tsim. Nyob rau lub sijhawm no, cov hlau nickel tuaj yeem ua tiav raws li qhov xav tau, xws li dov, kos duab, thiab lwm yam. Nyob rau tib lub sijhawm, cov khoom siv smelting kuj yuav tsum tau ntxuav thiab khaws cia rau kev siv tom ntej.
