Lub tswv yim thiab cov yam ntxwv ntawm silicon slag
Silicon slag yog hais txog cov khoom lag luam tsim tom qab smelting kaolin, limestone, quartz, coke hmoov thiab lwm yam khoom siv raw ntawm qhov kub thiab txias. Nws yog tsim los ntawm sodium aluminium silicate, potassium aluminium silicate, calcium silicate, magnesium silicate, thiab lwm yam. Silica slag yog cov khoom siv dub lossis grey granular nrog cov ntxhib thiab tsis sib xws thiab ntau qhov me me.
Silicon slag muaj cov yam ntxwv hauv qab no:
1. nplua nuj nyob rau hauv silicon thiab txhuas: Lub ntsiab Cheebtsam ntawm silicon slag yog cov tebchaw nplua nuj nyob rau hauv silicon thiab txhuas, yog li nws plays ib tug tseem ceeb luag hauj lwm nyob rau hauv steel smelting.
2. Txo cov pa roj carbon thiab sulfur cov ntsiab lus ntawm cov hlau: Cov txhuas hauv silicon slag tuaj yeem hnov mob nrog cov oxides hauv cov hlau, yog li txo nws mus rau cov hlau txhuas, tsim cov tshuaj insoluble nrog sulfides thiab oxides hauv cov hlau, txo cov Carbon thiab cov ntsiab lus sulfur. hauv steel.
3. Tiv thaiv lub qhov cub hauv ob sab phlu: Qhov kub ntawm cov silicon slag tuaj yeem tsim cov txheej txheem oxide ruaj khov los tiv thaiv cov cua kub kub hauv ob sab phlu los ntawm melted.
4. Ua kom ntau lawm: Qhov sib ntxiv ntawm silicon slag tuaj yeem ua kom nrawm thiab qib ntawm cov tshuaj tiv thaiv hauv lub cub tawg, yog li ua kom cov hlau ntau lawm.
5. Txo kev siv hluav taws xob: Kev sib ntxiv ntawm silicon slag tuaj yeem txo qhov kub thiab lub sijhawm ntawm cov tshuaj tiv thaiv hauv lub cub tawg, yog li txo lub zog noj.
Kev siv cov silicon slag hauv steelmaking
Silicon slag yog feem ntau siv los ntawm cov khoom hauv cov txheej txheem steel smelting. Nws plays lub luag hauj lwm nyob rau hauv ntau yam xws li nqi, slag, thiab furnace gas.
Nws daim ntawv thov hauv steelmaking feem ntau suav nrog cov hauv qab no:
1. Txo cov pa roj carbon thiab sulfur cov ntsiab lus hauv cov hlau: Ntxiv silicon slag tuaj yeem txo cov oxides thiab sulfides hauv cov hlau thiab txo cov carbon thiab sulfur cov ntsiab lus hauv cov hlau.
2. Tiv thaiv lub qhov cub hauv ob sab phlu: Silicon slag tuaj yeem tsim cov txheej txheem oxide tiv thaiv kom tsis txhob muaj qhov cub tawg.
3. Ua kom ntau lawm: Qhov sib ntxiv ntawm silicon slag tuaj yeem ua kom cov tshuaj tiv thaiv ceev thiab qib hauv lub cub tawg, yog li ua kom cov hlau ntau lawm.
4. Txo cov ntsiab lus oxide hauv cov slag: Silicon slag tuaj yeem txo cov ntsiab lus oxide hauv cov slag thiab txo cov ntsiab lus oxide hauv cov slag.
5. Txhim kho qhov zoo ntawm cov hlau molten: Silicon slag tuaj yeem txo cov ntsiab lus ntawm cov hlau tsis muaj hlau nyob hauv cov hlau, yog li txhim kho qhov zoo ntawm cov hlau molten.
Hauv cov ntsiab lus, silicon slag yog ib qho tseem ceeb ntawm cov khoom siv hlau thiab ua lub luag haujlwm tseem ceeb hauv cov txheej txheem steelmaking. Los ntawm kev nkag siab txog cov yam ntxwv thiab kev siv ntawm silicon slag, peb tuaj yeem ua kom zoo dua cov qauv thiab cov thev naus laus zis ntawm steel smelting thiab txhim kho kev tsim khoom thiab cov khoom zoo.
