Base Khoom siv rau Steel Production:
Cov hlau ntshiab yog cov khoom siv tseem ceeb hauv kev tsim steel. Los ntawm kev ntxiv cov ntsiab lus alloying thiab kho qhov muaj pes tsawg leeg, steel nrog ntau yam khoom tuaj yeem tau txais kom tau raws li cov ntawv thov sib txawv.
Txhim kho Steel Zoo:
Kev siv cov hlau ntshiab raws li cov khoom siv raw tuaj yeem txhim kho cov hlau zoo. Cov impurities nyob rau hauv raw cov ntaub ntawv yuav adversely cuam tshuam lub mechanical zog, corrosion kuj, thiab lwm yam ntxwv ntawm steel. Los ntawm kev pib nrog cov hlau ntshiab, qhov kev pheej hmoo ntawm impurity qhia tau txo qis, ua rau cov khoom siv hlau zoo dua.
Kev sib koom ua ke hauv Steel Composition:
Cov hlau ntshiab muab ib qho kev sib xyaw ua ke rau kev tsim steel. Qhov kev sib xws no ua kom ntseeg tau tias cov hlau tsim los ntawm tib pawg muaj cov khoom sib xws, uas yog qhov tseem ceeb rau cov ntawv thov uas xav tau cov khoom siv zoo.
Txhim kho Mechanical Properties:
Cov hlau ua los ntawm cov hlau ntshiab feem ntau nthuav tawm cov khoom siv kho kom zoo xws li lub zog tensile ntau dua, lub zog tawm los, thiab ductility. Cov khoom no yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev ua haujlwm ruaj khov thiab kav ntev.
Tswj Tshaj Alloying Elements:
Thaum tsim cov hlau los ntawm cov hlau ntshiab, cov tuam ntxhab tuaj yeem tswj xyuas qhov sib ntxiv ntawm cov ntsiab lus alloying. Qhov no tso cai rau kev tsim cov hlau nrog cov khoom tsim tshwj xeeb rau cov ntawv thov tshwj xeeb, xws li kev txhim kho corrosion los yog txhim kho machinability.
Tus nqi-kev ua tau zoo hauv kev tsim khoom:
Txawm hais tias cov hlau ntshiab yuav muaj tus nqi pib dua piv rau lwm cov khoom siv raw, nws siv tuaj yeem ua rau cov txheej txheem ntau lawm thiab txo cov pov tseg. Qhov no yog vim cov hlau ntshiab minimizes qhov yuav tsum tau rau nws kim heev refining thiab purification kauj ruam thaum lub sij hawm tsim steel.
Nyob rau hauv xaus, steel mills xaiv los yaj ntshiab hlau vim nws lub luag hauj lwm raws li ib tug tseem ceeb raw cov ntaub ntawv, nws muaj peev xwm los txhim kho steel zoo thiab sib xws, nws kev txhim kho ntawm txhua yam khoom, meej tswj cov alloying ntsiab, thiab nqi-zoo nyob rau hauv ntau lawm. Cov yam tseem ceeb no ua rau kev tsim cov khoom lag luam zoo steel uas ua tau raws li ntau hom kev thov.
