1. Silicon furnace smelting: Silicon furnace smelting yog cov txheej txheem hlau silicon smelting, uas feem ntau suav nrog blast furnace method, calcium carbide method thiab silica reduction method.
Txoj kev tawg rau qhov cub: silica yog tov nrog coke los yog pulverized thee thiab smelted nyob rau hauv lub cub tawg. Hauv qhov cub tawg, qhov kub thiab txias thiab txo qhov cua tsim los ntawm kev sib xyaw ntawm coke lossis pulverized thee txo cov silicon dioxide hauv silica rau nws cov xim silicon. Txoj kev no muaj cov nqi qis dua tab sis cov khoom purity qis dua.
Calcium carbide method: Sib tov silica nrog coke los yog pulverized thee thiab smelt nws nyob rau hauv lub cub tawg calcium carbide. Nyob rau hauv lub cub hluav taws xob calcium carbide, silica raug txo kom nws yog xim hlau silicon los ntawm arc cua sov. Tus nqi smelting ntawm txoj kev no yog siab dua, tab sis qhov purity ntawm cov khoom yog siab dua.
Silica txo txoj kev: Sib tov silica nrog coke los yog thee hmoov thiab smelt nws los ntawm ib tug txo qhov cub. Nyob rau hauv qhov txo qhov cub, silica raug txo kom nws yog xim hlau silicon los ntawm qhov kub thiab txias thiab txo qhov cua. Txoj kev no muaj cov nqi smelting nruab nrab thiab cov khoom purity siab.
2. Hluav taws xob rauv smelting: Hluav taws xob rauv smelting yog ib yam tshiab ntawm cov hlau silicon smelting txheej txheem, uas feem ntau muaj xws li hluav taws xob arc rauv txoj kev thiab kuj rauv txoj kev.
Fais fab arc rauv txoj kev: Muab silica thiab electrodes rau hauv hluav taws xob arc rauv, thiab txo cov silica rau hlau silicon los ntawm arc cua sov. Tus nqi smelting ntawm txoj kev no yog siab dua, tab sis qhov purity ntawm cov khoom yog siab dua.
Resistance furnace method: Muab cov silica thiab cov cua sov ua kom sov rau hauv lub qhov cub ua kom tsis muaj zog, thiab txo cov silica rau hlau silicon los ntawm cov cua sov ua haujlwm. Txoj kev no muaj cov nqi smelting nruab nrab thiab cov khoom purity siab.
Feem ntau, cov txheej txheem smelting ntawm hlau silicon feem ntau suav nrog silicon rauv smelting thiab hluav taws xob rauv smelting. Txhua tus txheej txheem muaj nws lub sijhawm thiab cov yam ntxwv, thiab cov yam ntxwv xws li cov nqi smelting thiab cov khoom purity kuj txawv. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, hluav taws xob rauv smelting thev naus laus zis tau siv ntau ntxiv hauv silicon hlau smelting. Raws li lub chaw tsim khoom ntawm silicon hlau, peb lub Hoobkas tau cog lus rau kev tsim thiab muag ntawm cov hlau silicon, muab cov neeg siv khoom siv hlau silicon ntawm cov qauv tsim nyog thiab ua tiav cov qauv.
