Khoom Description
Steelmaking yog cov txheej txheem nyuaj thiab kev ua haujlwm siab heev uas yuav tsum tau ua kom raug thiab saib xyuas kom meej. Kev tsim cov hlau zoo yuav tsum tau siv cov cuab yeej siv siab tshaj plaws thiab cov cuab yeej siv tau zoo tshaj plaws thiab cov txheej txheem muaj.
Ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws rau kev tsim steel yog cov pa roj carbon hlau spheroidized cored hlau. Tsim los txhim kho qhov zoo ntawm cov khoom hlau los ntawm kev txo cov impurities thiab ua kom muaj zog, spheroidized cored hlau yog qhov tseem ceeb rau kev ua haujlwm steel.
Spheroidization yog txheej txheem ntawm kev hloov cov hlau los ntawm nws lub xeev qub mus rau hauv ib daim ntawv sib npaug, globular. Cov txheej txheem no txo qhov tsis xws luag thiab ua rau cov neeg kho tshuab lub zog ntawm cov hlau, ua rau nws ruaj khov thiab tiv taus kev puas tsuaj.
Los ntawm kev siv cov pa roj carbon hlau spheroidized cored hlau, steelmakers tuaj yeem txhim kho lawv cov khoom zoo thiab ua kom lawv cov kev ua tau zoo. Cov thev naus laus zis no muab cov kev daws teeb meem zoo rau cov neeg tsim khoom steel uas tab tom nrhiav kev txhim kho lawv cov txheej txheem tsim khoom thiab txhim kho lawv cov khoom zoo.
Carbon hlau spheroidized cored hlau yog ntau yam cuab yeej uas yuav siv tau nyob rau hauv ntau yam steel ntau lawm txheej txheem. Nws tuaj yeem siv rau hauv qhov cub induction, hluav taws xob arc rauv, thiab cov pa oxygen yooj yim los tsim cov khoom siv hlau zoo.
Cov hlau yog tsim los ntawm cov khoom tseem ceeb uas nyob ib puag ncig ntawm lub plhaub carbon. Cov khoom tseem ceeb yuav muaj ntau yam sib txawv, suav nrog calcium, silicon, magnesium, thiab txhuas. Cov roj carbon plhaub muab kev tiv thaiv los ntawm oxidation thiab txo qhov kev pheej hmoo ntawm kev sib kis.
Lub spheroidized cored hlau yog ntxiv rau cov hlau molten thaum lub sij hawm tsim cov hlau. Thaum cov hlau nkag mus rau hauv kev sib cuag nrog cov hlau molten, nws tso tawm cov khoom tseem ceeb, uas cuam tshuam nrog cov hlau los tsim cov qauv ntau dua thiab spheroidized.
Cov txheej txheem no muaj ntau yam txiaj ntsig rau kev tsim cov hlau, nrog rau kev txhim kho cov neeg kho tshuab lub zog, txo qhov nro saum npoo, thiab nce ductility. Spheroidization kuj txo cov nqi zog uas yuav tsum tau ua rau steel ntau lawm, txuag ntawm cov nqi tsim khoom thiab txo cov kev cuam tshuam ib puag ncig ntawm steel ntau lawm.
Ntxiv rau nws cov txiaj ntsig kev lag luam, carbon hlau spheroidized cored hlau kuj muab steelmakers nrog cov txiaj ntsig nyiaj txiag tseem ceeb. Nrog rau cov thev naus laus zis no, steelmakers tuaj yeem tsim cov khoom lag luam zoo dua steel uas ua tau raws li lawv cov neeg siv khoom xav tau, ua rau cov nyiaj tau los thiab cov txiaj ntsig tau nce ntxiv.
Zuag qhia tag nrho, kev siv cov pa roj carbon hlau spheroidized cored xov hlau hauv steelmaking yog ib qho tseem ceeb ntawm cov txheej txheem steel niaj hnub no. Los ntawm kev siv cov thev naus laus zis tshiab no, cov tuam txhab steel tuaj yeem tsim cov khoom lag luam zoo steel uas ua tau raws li lawv cov neeg siv khoom xav tau thaum tseem txhim kho kev ua tau zoo thiab ib puag ncig ntawm lawv cov haujlwm.
Nyob rau hauv xaus, lub neej yav tom ntej ntawm steelmaking nyob rau hauv niaj hnub, tshiab technologies xws li carbon hlau spheroidized cored nyob ntawm tej. Los ntawm kev lees txais cov thev naus laus zis no, peb tuaj yeem ua kom zoo dua peb cov txheej txheem tsim khoom, txo peb cov kev cuam tshuam ib puag ncig, thiab muab cov khoom zoo steel uas ua tau raws li peb cov neeg siv khoom xav tau. Raws li peb txuas ntxiv tsim kho tshiab thiab txhim kho peb cov txheej txheem steel ntau lawm, peb tuaj yeem tos ntsoov rau yav tom ntej ntawm kev ruaj khov, ua haujlwm zoo, thiab ua tau zoo steelmaking.
