Vim li cas Alumina Siv dav hauv Kev Lag Luam Metallurgical?

Tus nasYog siv dav hauv kev lag luam metallurgical feem ntau vim hais tias nws plays lub luag haujlwm tseem ceeb hauv kev tsim cov kev lag luam txhuas thiab hauv kev lag luam steel. Nyob rau hauv cov nqe lus ntawm txhuas ntau lawm, alumina yog thawj cov ntaub ntawv raw rau kev ua yeeb yam metallic aluminium. Los ntawm cov txheej txheem tseem ceeb ntawm kev siv tshuab hluav taws xob Txij li txhuas nws tus kheej muaj ntau cov yam ntxwv zoo heev xws li ua lub zog, nws yog qhov zoo hluav taws xob, nws yog qhov tsim kho kom zoo li, uas ua rau alumina tseem ceeb heev raws li cov khoom siv rautooj dawbntau lawm. Hauv kev lag luam steel, alumina tuaj yeem ua kom zoo tshem tawm cov pa hauv Molten hlau, txo cov kev suav nrog hauv cov khoom siv steel, thiab tom qab ntawd txhim kho qhov zoo ntawm cov hlau. Piv txwv li, thaum tsim cov hmoov av zoo tagnrho, nws cov nyhuv ntawm kev txhim kho cov khoom xws li cov tawv tawv, lub zog thiab hnav tsis kam ntawm cov hlau yog qhov zoo tshaj plaws. Lub caij no, Alumina kuj yog cov khoom siv refractory zoo tshaj plaws uas siv rau cov ntaub pua hauv cov hlau smelting. Nws tuaj yeem tiv thaiv siab qhov chaw nyob ib puag ncig, tiv thaiv cov cua sov ntawm kev ua kom sov siab los ntawm kev kub siab molten steel thiab slag, thiab ntau kawg txuas lub neej ntawm cov cua sov lub cev.
