Khoom Description
Silicon slag yog ib yam khoom los ntawm cov khoom tsim nyob rau hauv cov txheej txheem kev lag luam tshwj xeeb thiab muaj ntau yam ntawm cov nqi siv. Cov ntsiab lus ntawm silicon slag feem ntau yog nyob nruab nrab ntawm 30% thiab 70%, thiab nws muaj lwm yam xws li txhuas, sulfur, phosphorus thiab carbon.
Silicon slag feem ntau yog tsim nyob rau hauv cov txheej txheem hauv qab no, xws li blast furnace smelting: nyob rau hauv lub qhov cub tawg, hlau ore yog pretreated thiab nkag mus rau hauv qhov cub tawg nrog coke. Thaum kub kub, hlau ore raug txo kom hlau thiab hlawv nrog coke, thiab slag tsim nyob rau hauv lub cub tawg ntws downstream, nrog rau silicon slag. Tseem muaj hluav taws xob rauv smelting: lub cub hluav taws xob heats ferrous alloys, seem hlau thiab lwm yam ntaub ntawv hlau mus rau melting point thiab ua lawv los ntawm arc cua sov. Nyob rau hauv cov txheej txheem smelting, lub cub tawg nqi melts mus rau hauv cov kua hlau tom qab cua sov, thiab nyob rau tib lub sij hawm, slag yuav ntab los ntawm cov hlau nto thiab muab sau, cov uas silicon slag yog ib yam ntawm cov slag residue sau nyob rau hauv lub smelting txheej txheem. Tsis tas li ntawd, nyob rau hauv tus txheej txheem ntawm txhuas electrolysis, alumina tov nrog ib tug loj concentration ntawm txog 500-600 g / L yog electrolyzed nyob rau hauv lub electrolytic cell thiab hloov mus rau hauv txhuas thiab los ntawm-ua oxides thiab silicon slag. Cov zis ntawm silicon slag yuav txawv vim cov txheej txheem electrolysis thiab raw khoom.
Silicon slag muaj ntau yam siv hauv kev lag luam, piv txwv li, silicon slag tuaj yeem siv los ua deoxidizer hauv cov txheej txheem steelmaking kom txo tau cov pa oxygen hauv cov txheej txheem melting thiab casting. Silicon slag kuj yog ib qho khoom siv pheej yig rau ntau qhov kev lag luam silicon, xws li kev tsim cov silicone. Silicon slag tuaj yeem txhim kho qhov cub kub, ua kom lub cev muaj zog ntawm cov hlau molten thiab ua kom zoo dua qhov toughness thiab txiav peev xwm ntawm castings. Nyob rau hauv nam ntawm flue gas desulfurization, qhov yooj yim oxide nyob rau hauv silicon slag tuaj yeem hnov mob nrog sulfur dioxide los tsim sulfate, yog li nws kuj yog siv rau flue gas desulfurization. Silicon slag tseem tuaj yeem siv rau hauv cov khoom siv hauv tsev, cov neeg ua haujlwm sib txhuam, cov tshuaj tua hluav taws hluav taws xob thiab lwm yam haujlwm, thiab tau siv rau hauv metallurgy, cement ntau lawm thiab lwm yam lag luam.
Silicon slag tuaj yeem muab faib ua kev lag luam silicon slag, hnub ci silicon slag thiab semiconductor silicon slag raws li qhov sib txawv thiab kev siv. Lwm qhov kev faib tawm yog raws li cov ntsiab lus sib txawv ntawm silicon, xws li ferrosilicon slag thiab nws yog xim hlau silicon slag. Silicon slag yog ib qho tseem ceeb ntawm kev lag luam los ntawm cov khoom lag luam nrog cov nqi siv dav. Los ntawm kev kho thiab kev siv kom zoo, cov peev txheej tuaj yeem siv tau zoo thiab kev ua qias tuaj ib puag ncig tuaj yeem txo.
