Silicon slag, ferrosilicon slag, thiab silicon hlau slag yog tag nrho cov byproducts ntawm silicon - raws li cov txheej txheem smelting. Lawv qhov sib txawv tseem ceeb nyob hauv lawv lub hauv paus chiv keeb, muaj pes tsawg leeg (tshwj xeeb yog cov ntsiab lus silicon thiab cov ntsiab lus tseem ceeb), thiab cov ntawv thov scenarios. Qhov tseeb qhov txawv ntawm qhov peb yog qhov tseem ceeb rau kev xaiv cov khoom siv hlau metallurgical auxiliary cov ntaub ntawv, cov khoom siv rov ua dua tshiab, thiab kev tswj cov nqi.
Kev sib piv ntawm cov yam ntxwv tseem ceeb ntawm peb

Nco tseg:Txawm hais tias tag nrho peb yog smelting byproducts, lawv cov compositions txawv heev vim yog cov khoom tseem ceeb sib txawv -silicon hlau slag yog tus cwj pwm los ntawm "silicon siab thiab tsawg hlau," ferrosilicon slag yog tus cwj pwm los ntawm "silicon nruab nrab thiab siab hlau," thiab zoo tib yam silicon slag feem ntau yog characterized los ntawm "tsawg silicon thiab siab impurities," uas ua rau kom muaj nuj nqis.
Kev piav qhia ntxaws los ntawm Hom
(1) Silicon Slag: Tsawg- tus nqi dav dav- lub hom phiaj los ntawm - khoom
Cov yam ntxwv sib xyaw: Cov ntsiab lus ntawm silicon qis tshaj plaws (10% -25%), impurities feem ntau yog CaO, Al₂O₃, thiab SiO₂, suav txog ntau dua 60%, nrog rau qhov qis ntawm cov khoom siv tau zoo;
Tsim Mechanism: Ib qho kev sib xyaw slag tsim nyob rau hauv smelting ntawm silicon alloys thaum lub ore tsis tas txo los yog reacts nrog rau lwm yam, tsis muaj lub ntsiab ntsiab lus qhia;
Cov ntawv thov tseem ceeb:
Cov Khoom Siv Hauv Tsev: Tom qab crushing, nws tuaj yeem siv los ua cov pob zeb sib sau ua ke thiab txoj kev hauv paus muab tub lim, hloov cov xuab zeb thiab pob zeb, nrog tus nqi ib tuj uas yog 30% -40% qis dua cov xuab zeb thiab pob zeb;
Cement Additives: Siv los ua cov khoom siv cement, siv nws cov SiO₂ thiab CaO cov khoom los txo cov cement firing zog noj;
(2) Ferrosilicon Slag Slag: Nruab Nrab- nqi alloy rov siv cov khoom siv raw
Cov yam ntxwv muaj pes tsawg leeg: Cov ntsiab lus nruab nrab silicon (20% -35%), cov ntsiab lus hlau siab (15% -25%), muaj qee qhov tsis zoo ferrosilicon hais (FeSi);
Kev tsim cov txheej txheem: Hauv ferrosilicon smelting, txo cov tshuaj tiv thaiv ntawm silica thiab hlau nplai tsis tiav, los yog cov khoom me me ferrosilicon yog nqa tawm nrog cov slag thaum tawm hauv lub cub tawg, khaws qee cov yam ntxwv ntawm alloy;
Cov ntawv thov tseem ceeb:
Recycled alloy ntau lawm: Tom qab crushing, nws yuav rov qab mus rau lub ferrosilicon smelting rauv los hloov ib feem ntawm silica thiab hlau raw cov ntaub ntawv, txo tus nqi ntau lawm ib tuj ntawm ferrosilicon los ntawm 8% -12%;
Hnav-cov ntaub ntawv tiv taus: Sib xyaw nrog lwm cov khib nyiab pov tseg los npaj hnav-cov ntaub ntawv pov thawj resistant, nrog rau hardness (HB) ntawm 180-220, haum rau lub Hoobkas rhiav pem teb;
(3) Silicon hlau Slag: Siab -tus nqi metallurgical auxiliary khoom
Cov yam ntxwv muaj xws li: Cov ntsiab lus silicon siab tshaj plaws (40% -65%), cov ntsiab lus hlau tsawg (tsawg dua lossis sib npaug li 5%), impurities feem ntau yog Al₂O₃, CaO Feem ntau yog tsim los ntawm silicon (30% -50%), muaj qhov tseem ceeb ntawm cov hlau tsis muaj hlau silicon.
Tsim Mechanism: Thaum lub sij hawm nws yog xim hlau silicon smelting (1800{1}}2000 degree), qhov txo qis ntawm silica tshwm sim, los yog silicon-nplua nuj slag ntab rau saum npoo ntawm cov hlau molten thaum tapping, khaws qee qhov reactivity ntawm hlau silicon.
Cov ntawv thov tseem ceeb:
Steelmaking Deoxidation: Hloov ib feem ntawm ferrosilicon, nrog rau qhov sib ntxiv ntawm 1.5% -2.0%, txo cov pa oxygen ntawm molten steel los ntawm 80ppm mus rau 50-60ppm, nrog deoxidation nqi 25% -30% qis dua ferrosilicon.
Kev Npaj Alloy: Siv los ua cov khoom siv raw hauv silicon-raws li alloys (xws li silicon-manganese thiab silicon-calcium alloys), ntxiv silicon thiab txo cov nqi ntawm cov khoom siv tseem ceeb.
Chemical Raw Khoom: Extracts elemental silicon rau kev npaj ntawm qis -purity organosilicon intermediates, ua tiav silicon hloov pauv tus nqi ntawm 60%-70%.
