Cov hlau cored yog siv los qhia cov ntaub ntawv no rau hauv lub tshuab ua hlau, qhov chaw uas lawv hnov mob nrog cov hlau molten los txhim kho nws cov khoom zoo thiab cov khoom. Hauv tsab xov xwm no, peb yuav tham txog kev siv cov cored hlau hauv cov txheej txheem steelmaking, nws qhov zoo, thiab qhov tsis zoo, thiab ntau hom cored hlau muaj nyob hauv khw.
Dab tsi yog cored hlau?
Cored hlau yog ib hom hlau uas muaj cov tub ntxhais hlau thiab txheej txheej ntawm ntau yam ntaub ntawv, xws li calcium, magnesium, thiab txhuas. Cov tub ntxhais hlau feem ntau yog ua los ntawm cov hlau, hlau, lossis cov hlau tsis muaj steel, thaum txheej txheej yog ua los ntawm ntau yam khoom siv los qhia cov ntsiab lus tshwj xeeb rau hauv cov hlau molten thaum lub sij hawm ua cov txheej txheem steel. Lub coated hlau yog coiled rau ntawm ib tug spool thiab pub rau hauv steelmaking rauv, qhov twg cov txheej yog raug rau cov hlau molten, thiab cov khoom nyob rau hauv lub txheej reacts nrog cov hlau los tsim cov nyhuv xav tau.
Yuav ua li cas yog cored hlau siv nyob rau hauv cov txheej txheem steelmaking?
Cored hlau yog siv rau hauv cov txheej txheem steelmaking los qhia cov ntsiab lus tshwj xeeb rau hauv cov hlau molten, xws li calcium, magnesium, thiab txhuas. Cov ntsiab lus no tau qhia rau cov hlau thaum lub sij hawm sib txawv ntawm cov txheej txheem steelmaking, xws li lub ladle furnace thiab tundish. Lub cored hlau yog pub rau hauv lub cub tawg, qhov twg nws melts, thiab lub txheej tso tawm cov khoom mus rau hauv lub molten hlau. Cov khoom siv reacts nrog cov hlau los tsim cov nyhuv uas xav tau, xws li tshem tawm cov impurities, tswj cov nplej loj, thiab txhim kho cov khoom siv ntawm cov hlau.
Qhov zoo ntawm kev siv cored hlau
Muaj ntau qhov zoo ntawm kev siv cored hlau hauv cov txheej txheem steelmaking. Qee qhov no suav nrog:
1. Txhim kho steel zoo: Cored hlau yog siv los qhia cov ntsiab lus tshwj xeeb rau hauv cov hlau, uas tuaj yeem pab txhim kho nws qhov zoo los ntawm kev tshem tawm cov impurities, tswj cov nplej loj, thiab txhim kho cov khoom siv ntawm cov hlau.
2. Cov txiaj ntsig zoo dua: Kev siv cov hlau cored tuaj yeem pab txhim kho cov txiaj ntsig ntawm cov txheej txheem steelmaking los ntawm kev txo cov khoom seem ntawm cov hlau uas tsim tawm.
3. Kev ua kom muaj zog ntxiv: Cored hlau tuaj yeem pab txo cov khoom siv uas xav tau los tsim cov hlau zoo, uas tuaj yeem pab txhim kho cov txheej txheem steelmaking.
4. Tus nqi zoo: Kev siv cov hlau cored yog tus nqi zoo piv rau lwm txoj hauv kev los qhia cov ntsiab lus no rau hauv cov hlau, xws li kev sib ntxiv ntawm cov hlau.
Disadvantages ntawm kev siv cored hlau
Txawm hais tias qhov zoo ntawm kev siv cored hlau hauv cov txheej txheem steelmaking, muaj qee qhov tsis zoo los xav txog. Qee qhov no suav nrog:
1. Kev phom sij rau kev noj qab haus huv: Cov txheej txheej ntawm cov khoom siv hlau cored tuaj yeem tsim kev puas tsuaj rau cov neeg ua haujlwm nrog cov hlau yog tias tsis ua raws li kev ntsuas kev nyab xeeb.
2. Kev cuam tshuam ib puag ncig: Kev tsim cov hlau cored tuaj yeem muaj kev cuam tshuam ib puag ncig, vim nws xav tau lub zog thiab cov peev txheej los tsim.
3. Cia thiab tuav: Cored hlau yuav tsum tau muab khaws cia thiab tuav kom zoo kom tsis txhob muaj kev puas tsuaj rau cov txheej txheem thiab xyuas kom meej tias cov khoom siv nkag mus rau hauv cov hlau kom raug thiab raws sijhawm.
Hom cored hlau
Muaj ntau ntau hom cored hlau muaj nyob rau hauv kev ua lag luam, txhua tus muaj nws tus kheej cov khoom thiab qhov zoo. Qee yam uas feem ntau muaj xws li:
1. Calcium cored hlau: Hom cored hlau no yog siv los qhia calcium rau hauv cov hlau, uas yuav pab tshem tawm impurities thiab tswj cov nplej loj.
2. Magnesium cored hlau: Magnesium cored hlau yog siv los qhia magnesium rau hauv cov hlau, uas yuav pab txhim kho nws cov khoom siv, xws li ductility, toughness, thiab tsis kam mus corrosion.
3. Aluminium cored hlau: Hom cored hlau no yog siv los qhia cov txhuas rau hauv cov hlau, uas yuav pab txhim kho nws lub zog thiab tiv thaiv corrosion.
4. Khoom-cored hlau: Cov khoom siv-cored hlau yog ib hom cored hlau uas tsis muaj txheej txheej thiab siv los qhia cov ntsiab lus rau hauv cov hlau hauv lawv daim ntawv ntshiab.
Xaus
Cored hlau yog ib qho tseem ceeb ntawm cov txheej txheem steelmaking. Nws yog siv los qhia cov ntsiab lus tshwj xeeb rau hauv cov hlau molten, xws li calcium, magnesium, thiab txhuas, uas tuaj yeem pab txhim kho qhov zoo thiab cov khoom ntawm cov hlau. Cored hlau muaj ntau yam zoo, xws li kev txhim kho steel zoo, yield zoo dua, nce efficiency, thiab nqi-zoo. Txawm li cas los xij, kuj tseem muaj qee qhov tsis zoo los xav txog, xws li kev phom sij rau kev noj qab haus huv, kev cuam tshuam ib puag ncig, thiab kev cia khoom thiab kev tuav pov hwm. Nrog rau ntau hom cored hlau muaj nyob rau hauv kev ua lag luam, nws yog ib qho tseem ceeb uas yuav tau xaiv txoj cai ntawm cov hlau rau daim ntawv thov tshwj xeeb kom ntseeg tau tias kev ua tau zoo thiab zoo.
