Daim ntawv thov ntawm blast furnace slag thiab steel slag yog tam sim no loj hlob sai nyob rau hauv cov hlau thiab steel kev lag luam, thiab cov paug ntawm cov khib nyiab slag yog nce ib hnub twg. Blast furnace slag yog cov slag tawm los ntawm kev ua hlau, thiab steel slag yog cov slag tawm los ntawm cov txheej txheem steelmaking. Kev tso tawm ntawm cov khib nyiab pov tseg no ua rau muaj kev ua qias tuaj ib puag ncig thiab pov tseg cov peev txheej. Lub ntsiab Cheebtsam ntawm blast furnace slag yog oxides xws li CaO, MgO, Al2O3, SiO2, thiab ib tug neeg slags kuj muaj TiO2, V2O5, thiab lwm yam. Cov tshuaj muaj pes tsawg leeg sib txawv raws li hom hlau smelting. Yog hais tias nws yog ib qho tshwj xeeb blast furnace slag, cov tshuaj muaj pes tsawg leeg yuav tsum ruaj khov. Tsis tas li ntawd, ntau hom blast furnace slag muaj cov yam ntxwv zoo, uas yog, lawv tsis muaj cov oxides dawb, tshwj xeeb tshaj yog dawb calcium oxide.
Kev siv pov tseg hauv cov ntaub ntawv refractory tau ua tiav zoo hauv xyoo tas los no. Txawm li cas los xij, vim muaj qhov tsis zoo hauv kuv lub teb chaws cov khoom pov tseg thiab tib neeg tsis muaj cov tswv yim rov ua dua tshiab, kev siv cov khoom pov tseg hauv cov ntaub ntawv refractory yog qhov tseem ceeb heev. nqaim. Vim li no, thaum ntxiv dag zog rau tib neeg txoj kev paub thiab cov tswv yim, kev lag luam pov tseg yog siv ntau txoj hauv kev, ntau txoj hauv kev, thiab ntau theem kom paub txog cov peev txheej rov qab siv dua.
Los ntawm qhov kev xav ntawm hom thiab kev ua tau zoo ntawm cov khoom siv refractory, kev siv cov khoom siv pov tseg yog raws li hauv qab no: (1) Cov ntaub ntawv pov tseg refractory tuaj yeem siv ncaj qha lossis siv ncaj qha rau qib qis; (2) Cov ntaub ntawv pov tseg muaj raug purified los yog ua ntej homogenized los npaj cov khoom siv refractory siab. Khoom siv; (3) Cov khoom siv khib nyiab tau ua tiav ncaj qha raws li cov khoom siv raw khoom; (4) Cov hlau oxides tau muab rho tawm los ntawm cov khoom pov tseg raws li cov khoom siv raw khoom refractory; (5) Siv los ua cov khoom siv ntxiv (xws li cov hlua khi, cov tshuaj tiv thaiv dej, thiab lwm yam) hauv cov ntaub ntawv refractory.
Txawm hais tias tseem muaj qee qhov sib txawv ntawm qhov xwm txheej ntawm kev siv pov tseg hauv thaj tsam ntawm refractories hauv kuv lub teb chaws thiab cov teb chaws tsim, nws tau sau cov kev paub zoo uas tau tsav los ntawm kev nce qib hauv kev lag luam. Nyob rau tib lub sijhawm, ib qho teeb meem uas yuav tsum tau daws yog los hloov cov kev ua tiav no rau hauv kev tsim cov khoom siv refractory kom ua tiav lub hom phiaj ntawm kev lag luam. Hais txog qhov no, kuv lub teb chaws technology tseem tsis tau paub tab. Txawm hais tias qee qhov kev sim tau ua tiav hauv chav kuaj, muaj qee qhov kev tshaj tawm txog kev lag luam. Qhov no kuj yog ib qho teeb meem uas cov kws tshawb fawb tam sim no xav txog. Nws yog qhov pom tau tias thaum qhov teeb meem no tau kov yeej, kev siv cov khoom pov tseg hauv cov khoom siv hluav taws xob yuav tsis ntseeg tias yog ib qho tseem ceeb ntawm kev siv cov khoom pov tseg.
Kev xaus tam sim no, kev siv cov khoom pov tseg hauv cov khoom siv hluav taws xob hauv peb lub teb chaws tseem nyob rau theem pib ntawm kev tshawb fawb thiab kev tsim kho, thiab cov cuab yeej technology thiab cov txheej txheem tseem tsis tau paub tab, thiab xav tau kev tshawb nrhiav thiab kev txhim kho ntxiv. Yog tias cov khib nyiab tuaj yeem ua tau zoo thiab kho tau yooj yim, kev lag luam thiab tsim nyog thev naus laus zis los txhim kho kev ua haujlwm ntawm cov ntaub ntawv refractory, qhov no muaj qhov tseem ceeb rau kev siv cov khoom pov tseg. Tsis tas li ntawd, txoj kev loj hlob loj ntawm kev kho cov khib nyiab thiab kev siv thev naus laus zis tseem yuav ua rau muaj kev tshawb fawb thiab kev loj hlob ntawm kev siv cov khib nyiab hauv cov khoom siv refractory. Thaum daws teeb meem ib puag ncig thiab lub zog, nws kuj txhawb kev tsim cov khoom siv refractory. Nyob rau yav tom ntej, kev lag luam daim ntawv thov kev cia siab ntawm seem hauv cov ntaub ntawv refractory yuav dav heev.
