Koj puas tau tso tseg kom paub txog nws? puas ntxivCalcium Silicon rau steel tiag tiag tsuas yog ntxiv rau tus nqi, lossis nws puas coj tau nyiaj ntau dua? Dab tsi yog tus nqi tiag tiag ntawm cov hlau no thaum peb tab tom tham txog cov hlau zoo xws li cov hlau rail hlau lossis stainless hlau?
Kev Lag Luam Case: Deconstructing Tus Nqi
1. Tus nqi ncaj qha
Qhov no yog qhov yooj yim tus nqi ntawm covCaSihlau alloy.
Piv txwv li: Yog tias CaSi cored hlau yog $ 3 / kg thiab tus nqi ntxiv yog 2.0 kg / ton, tus nqi ncaj qha tsuas yog $ 6 USD / ton. Rau premium steel muag rau ntau txhiab ib tuj, qhov no yog negligible.
2. Tus nqi tsis ncaj (Qhov rov qab tiag tiag)
Qhov no yog qhov tseeb economic hwj chim nyob. Qhov ntawd $6 peev nyiaj tau los li cas?
A.Zoo hwm & Kev lag luam nkag: Tsis muajCaSi, steel tej zaum yuav ua tsis tau cov qauv tseem ceeb rau toughness los yog HIC tsis kam, muag tsuas yog cov khoom qis - qib. Nrog CaSi, nws ua tau raws li API nruj lossis cov qauv tsheb, dhau los ua cov khoom muaj txiaj ntsig siab - tus nqi uas hais kom tus nqi them ntau pua lossis ntau txhiab daus las ib tuj.
B.Txo qhov tsis lees paub & seem: Kev tsim cov khoom siab -kawg steel tawm me me rau qhov yuam kev. Yog tias 100-tuj cua sov tsis raug tshuaj xyuas vim muaj qhov tsis xws luag, kev poob nyiaj txiag tuaj yeem ua rau muaj kev puas tsuaj loj. Daim ntawv thov zoo ib yam ntawm CaSi ua raws li qhov tseem ceeb "kev pov hwm," tiv thaiv kev poob loj thiab ua rau kev tsim khoom tuaj yeem kwv yees.
C.Txhim khu kev ua tau zoo: Kev huv, zoo-kho steel ua kom smoother nruam nruam casting thiab dov, ua rau kom muaj zog ntau dua thiab tsawg dua kev cuam tshuam rau kev kho.
D.Tus nqi rau Koj Cov Neeg Siv Khoom: Thaum koj cov neeg siv khoom siv cov hlau kho nrog CaSi, lawv muaj kev vam meej dua hauv kev vuam thiab kev sib sau. Qhov no txhim kho koj lub hom phiaj kev ntseeg siab thiab kev sib tham muaj zog.
Xav txog Calcium Silicon raws li "cov khoom zais cia" hauv cov zaub mov noj. Ib pluas mov yooj yim tsis xav tau. Ib tug masterpiece (high-qib steel) nyob ntawm nws los txhais nws qhov kawg zoo thiab tus nqi. Rau txhua tus neeg tsim khoom lag luam tsom mus rau siab - tus nqi lag luam, siv CaSi tsis yog hais txog kev nce nqi; nws yog hais txog kev nqis peev hauv tus nqi nrog tus nqi nkag me me thiab qhov zoo tshaj plaws rov qab los.
Cov Tub Ntxhais Kawm Txuj Ci: Yuav Ua Li Cas Calcium Silicon Unlocks Steel's Potential
Qhov cuam tshuam loj heev ntawm CaSi stems los ntawm ib qho tseem ceeb mechanism: Inclusion Modification.
Hauv cov hlau tsis kho, sulfur tsim manganese sulfide (MnS) suav nrog. Thaum lub sij hawm kub dov, cov no elongate mus rau nyias, rab koob -zoo li strips uas ua zoo li microscopic "crack- pib qhov chaw," ua rau tsis zoo toughness.
Calcium yog reactive dua manganese. Nws hloov cov kab teeb meem no mus rau hauv cov kheej kheej, zoo - sib cais sib cais. Cov spheres me me no muaj qhov cuam tshuam tsawg kawg nkaus ntawm kev ntxhov siab, ua kom tshem tawm lawv qhov cuam tshuam tsis zoo.
Qhov kev hloov pauv tseem ceeb no ua rau:
Kev Txhim Kho Kev Nyuaj Siab Zoo Tshaj Plaws: Kev sib koom ua ke tsis yog "txoj kev loj rau kev tawg."
Txhim kho Isotropy: Cov khoom siv tshuab ua kom zoo ib yam hauv txhua qhov kev qhia.
Ua kom muaj zog ntxiv rau HIC & SSCC: Qhov tseem ceeb rau cov raj xa dej kom tsis txhob muaj kev puas tsuaj loj.
Zoo dua Weldability & Formability: Cov hlau ua tau zoo dua hauv kev tsim khoom hauv qab.
Txhim kho Nto Zoo: Calcium kuj hloov kho alumina inclusions, tiv thaiv nozzle clogging thiab txhim kho castability.
Hauv kev xaus, qhov kev txiav txim siab siv Calcium Silicon yog kev nqis peev zoo hauv kev ua tau zoo, tsis yog tus nqi ntxiv. Nws yog kev nqis peev me me uas qhib qhov muaj txiaj ntsig loj, muaj txiaj ntsig zoo, thiab kev ua lag luam kev coj noj coj ua.
Vim li cas koom tes nrog Peb Ferroalloy?
Txhawm rau kom ntseeg tau tias qhov kev nqis peev no muab nws cov nyiaj tau los siab tshaj plaws, tus neeg muag khoom ntseeg tau yog qhov tseem ceeb.
