Nrog rau kev txhim kho kev lag luam mining, npua hlau kev faib tawm hauv Peb lub teb chaws tau dav heev, kom tau raws li qhov xav tau ntawm kev lag luam tshuab.Feem ntau hais lus, hlau hlau Hoobkas tsimgalvanized hlau hlauhlau tuaj yeem muab faib ua ob pawg, yog ncaj qha los ntawm cov hlau ore los ntawm cov hlau tracing tawm ntawm cov hlau, cov khoom tseem ceeb ntawm cov ore yog hlau oxide, silica thiab lwm yam pob zeb.Thaum cov ore no tshwj xeeb refined rau hauv hlau hlau, cov ntsiab lus xws li carbon, silicon, manganese thiab thiaj li nyob rau hauv, yog li ntawd cov ntaub ntawv refined hu ua - zoo li cov npua hlau, kuj rau thawj qib ntawm cov khoom.
Raws li cov kev xav tau sib txawv ntawm kev lag luam, qhov sib txawv ntawm qhov sib txawv ntawm cov khoom sib txawv yog muab tso rau hauv lub qhov cub smelting raws li tus qauv, xws li weaving, Ming, ntawv, lang, silicon, thiab lwm yam, thiab cov ntaub ntawv tawm ntawm qhov smelting no hu ua kub. ore hlau.Hlau muaj grey hlau, hlau dawb thiab cov lus hais saum toj no, lawv muaj cov yam ntxwv sib txawv, yog li hauv kev lag luam raws li lawv cov yam ntxwv sib txawv rau kev thauj thiab xaiv.Piv txwv li, nyob rau hauv grey hlau, nws cov carbon muaj nyob rau hauv hlau ore nyob rau hauv graphite mob, lub tawg yog feem ntau grey, mos thiab muaj zog, yooj yim filtering, haum rau casting.
Nyob rau hauv cov hlau dawb, nws cov pa roj carbon thiab hlau ua ke rau hauv cov hlau carbide, tawg tshwm dawb, muaj zog heev thiab nkig zoo, rau cov khoom ntawm malleable hlau.Qib alloy muaj ntau yam alloying ntsiab nrog sib txawv compositions thiab cov qauv.Vim hais tias alloying ntsiab nyob rau hauv hlau ore yuav ua tau tooj liab los ntawm cov khoom thickening degree ntawm ntxiv dag zog rau, hardness, cuam tshuam quab yuam, lub zog tsis kam, kaw tus nqi, elongation, yog li alloying hlau nyob rau hauv cov kev ua ntawm cov hlau zoo, yog lub hauv paus ntsiab lus ntxiv.
Lub ntsiab yam tseem ceeb ua rau hlau xeb: txheeb ze av ntawm qhov chaw nyob rau tib qhov kub thiab txias, feem pua ntawm cov dej vapor ntsiab lus thiab dej vapor saturation cov ntsiab lus nyob rau hauv cov huab cua, hu ua txheeb ze humidity.Nyob rau hauv qee qhov txheeb ze av noo, tus nqi corrosion ntawm hlau antirust roj yog me me, tab sis siab dua qhov txheeb ze cov av noo, tus nqi corrosion nce dheev.Qhov txheeb ze humidity no hu ua qhov tseem ceeb humidity.Thaum cov av noo nyob rau hauv cov huab cua siab tshaj qhov tseem ceeb cov av noo, cov hlau nto yuav tshwm sim dej zaj duab xis los yog dej tee dej, yog hais tias lub cua muaj teeb meem impurities, yaj nyob rau hauv cov dej zaj duab xis, dej droplets, electrolytes thiab aggravate corrosion.
