1. 2 mus rau 3 hloov ua ntej refining, nws yog ib qho tsim nyog yuav tau pib txo cov electrode kom ntau li ntau tau los xyuas kom meej tias qhov kawg ntawm cov electrode ua haujlwm ntev txaus thiab tuaj yeem nkag siab tob rau hauv lub cub tawg kom sov lub qhov cub hauv qab thiab nce qhov cub kub;
2. Pib txo qis cov khoom siv yim teev ua ntej ua kom zoo dua qub, thiab sim txo cov 45 ferrosilicon cov ntaub ntawv khaws cia hauv qhov cub;
3. Cov ntsiab lus ntawm silicon ntawm cov hlau yuav tsum tau tswj kom ze rau ntawm qhov txwv sab saud;
4. Tom qab cov khoom siv qis dua, tsis txhob ntxiv 45 ferrosilicon cov ntaub ntawv, pib ntxiv 4 mus rau 5 batches ntawm cov khoom siv rau cov khoom siv hluav taws xob tsis muaj cov khoom siv hlau (cov khoom siv ntawm cov silica yog 200 kg), thiab tom qab ntawd tso tawm lub qhov cub kawg ntawm 45 ferrosilicon cov ntaub ntawv, thiab sim. ua kom cov hlau Net, raws li kev txheeb xyuas cov ntsiab lus ntawm cov hlau nyob rau hauv pem hauv ntej ntawm lub cub tawg, ntxiv ib qho tsim nyog ntawm cov hlau scraps rau lub molten hlau ladle thiab kho cov khoom tsim nyog (tseem 45 ferrosilicon);
5. Txuas ntxiv cov nqi hluav taws xob tsis muaj cov khoom siv hlau. Feem ntau, lub cub tawg ntawm ferrosilicon tuaj yeem tsim tau hauv 5 mus rau 6 teev. Thaum nws tsim nyog, pib ntxiv 75 ferrosilicon cov ntaub ntawv. Ceev faj kom tsis txhob nce cov khoom siv sai heev thaum ntxiv cov khoom siv. Txhawm rau tsim lub cub tawg ntawm ferrosilicon, yuav tsum tau siv lub ladle tshiab.
