Qhov sib txawv tseem ceeb ntawm daim txhuam cev hlau thiab npua hlau yog tias peb tuaj yeem tsim daim txhuam cev hlau los ntawm kev txo cov hlau ore los ntawm kev txo cov neeg ua hauj lwm thaum cov hlau npua yog los ntawm melting hlau ore nrog charcoal thiab limestone ntawm high pressures.
Npaj hlau thiab npua hlau yog cov hlau sib txawv uas peb tuaj yeem tsim tau los ntawm cov hlau ore uas tshwm sim hauv qab lub ntiaj teb. Ob leeg npua hlau thiab daim txhuam cev hlau muaj ntau yam siv vim qhov sib txawv ntawm cov khoom. Txawm hais tias muaj qhov zoo sib xws, kuj tseem muaj qee qhov sib txawv ntawm npua thiab daim txhuam cev hlau uas peb yuav tham hauv kab lus no.
Daim txhuam cev Iron yog dab tsi?
Sponge hlau yog ib hom hlau uas peb tuaj yeem tsim ncaj qha los ntawm cov hlau ore los ntawm kev txo qis. Qhov no yog vim li cas peb tuaj yeem hu nws kuj yog "cov hlau txo qis ncaj qha". Nyob ntawd, cov ore yog raug rau ntau yam txo cov neeg ua haujlwm xws li cov pa roj carbon monoxide lossis cov pa roj uas tawm los ntawm cov thee. Tsis tas li ntawd, peb tuaj yeem tsim daim txhuam cev hlau los ntawm ntau hom rauv xws li blast furnace, charcoal ncu thiab oxygen furnaces.
Daim txhuam cev hlau muaj ntau yam zoo dua lwm cov ntaub ntawv zoo sib xws. Daim txhuam cev hlau yog superior rau npua hlau vim nws yog nplua nuj nyob rau hauv cov ntsiab lus hlau. Vim hais tias ntawm cov cuab yeej no, nws muaj ntau yam siv nyob rau hauv hluav taws xob furnaces. Peb tuaj yeem sib tov daim txhuam cev hlau, hauv nws daim ntawv hmoov nrog ntau lwm cov hlau los tsim ntau yam khoom uas muaj hlau.
Daim duab 01: Hlau Bloom (sponge yog Bloomery khoom)
Piv txwv li, peb tuaj yeem tsim cov hlau wrought los ntawm daim txhuam cev hlau. Nws yog ib hom hlau uas peb siv los ua cov khoom ornamental xws li grills thiab patio rooj tog. Wrought hlau rooj tog yog nyob rau hauv kev thov siab thiab kav ntev rau xyoo yog tias peb saib xyuas nws kom raug. Cov txheej txheem tshiab tshaj plaws ntawm kev ua daim txhuam cev hlau tau ua tiav nrog kev siv cov pa roj; yog li no, tsis tas yuav yaj cov ore txawm.
Pig Hlau yog dab tsi?
Npua hlau yog ib hom hlau uas peb tuaj yeem tsim tau los ntawm cov hlau melting ore nrog rau charcoal thiab limestone nyob rau hauv siab heev. Tom qab txias, cov khoom tshwm sim, uas peb hu ua npua hlau yog ib daim ntawv hlau uas muaj cov ntsiab lus carbon siab heev. Yog li, nws dhau los ua nkig thiab tsis ruaj khov uas peb tsis tuaj yeem siv ncaj qha rau hauv daim ntawv no.
Daim duab 02: Pom tus npua hlau
Txawm li cas los xij, peb tuaj yeem kho cov hlau no los ntawm kev sib txuas ntxiv thiab sib tov los tsim cov hlau wrought, cam khwb cia hlau thiab hlau uas muaj txiaj ntsig zoo li cov khoom siv. Npua hlau ntseeg tau pom los ntawm Suav smiths nyob rau hauv lub xyoo pua 11th. Npua hlau nyob rau hauv nws daim ntawv tseeb yog tsis muaj txiaj ntsig, tab sis ntxiv ua thiab refining ua rau wrought hlau thiab hlau uas yog ua ke cov khoom siv dav hauv ntiaj teb.
Qhov txawv ntawm daim txhuam cev hlau thiab npua hlau yog dab tsi?
Sponge hlau yog ib hom hlau uas peb tuaj yeem tsim ncaj qha los ntawm cov hlau ore los ntawm kev txo qis thaum npua hlau yog ib hom hlau uas peb tuaj yeem tsim tau los ntawm melting hlau ore nrog rau charcoal thiab limestone nyob rau hauv siab heev. Yog li ntawd, qhov sib txawv tseem ceeb ntawm daim txhuam cev hlau thiab npua hlau yog tias peb tuaj yeem tsim cov sponge hlau los ntawm kev txo qis ntawm cov hlau ore los ntawm kev txo cov neeg ua hauj lwm thaum cov npua hlau yog los ntawm melting hlau ore nrog charcoal thiab limestone ntawm high pressures.
Tsis tas li ntawd, lwm qhov sib txawv ntawm daim txhuam cev hlau thiab npua hlau yog tias daim txhuam cev hlau yog ntxeem tau thaum npua hlau tsis ntxeem tau, thiab yog li, piv txwv li denser. Tsis tas li ntawd, tseem muaj qhov sib txawv ntawm daim txhuam cev hlau thiab npua hlau hauv lawv cov txheej txheem tsim khoom. Qhov ntawd yog; cov txheej txheem tsim cov sponge hlau yog cov txheej txheem ua kua hauv lub xeev whereas nws yog cov txheej txheem hauv xeev rau npua hlau.
Summary – Sponge Iron vs Pig Iron
Ob daim txhuam cev hlau thiab npua hlau yog ob hom hlau uas peb tuaj yeem tau txais los ntawm kev ua cov hlau ore. Qhov sib txawv tseem ceeb ntawm daim txhuam cev hlau thiab npua hlau yog tias peb tuaj yeem tsim cov sponge hlau los ntawm kev txo cov hlau ore los ntawm kev txo cov neeg ua hauj lwm thaum cov npua hlau yog los ntawm melting hlau ore nrog charcoal thiab limestone ntawm high pressures.
