Hauv ntiaj teb kev tsim kho thiab kev tsim khoom, kev xaiv cov ntaub ntawv yog qhov tseem ceeb rau kev ua kom ruaj khov, muaj zog, thiab tsim nyog tus nqi. Ntawm ntau yam ntaub ntawv muaj, cov phaj hlau carbon sawv tawm vim lawv qhov kev hloov pauv tau yooj yim thiab kev ua tau zoo. Ntawm Jindalai Steel Company, lub tuam txhab tsim cov phaj hlau carbon ua ntej, peb tshwj xeeb hauv kev tsim cov phaj hlau carbon zoo, suav nrog cov phaj hlau carbon ru tsev, tsim los ua kom tau raws li ntau yam kev xav tau ntawm peb cov neeg siv khoom.
Kev Sib Xyaws thiab Kev Faib Tawm ntawm Cov Phaj Hlau Carbon
Cov phaj hlau carbon feem ntau yog ua los ntawm hlau thiab carbon, nrog rau cov pa roj carbon feem ntau yog li ntawm 0.05% txog 2.0%. Cov khoom sib xyaw no cuam tshuam rau cov khoom siv kho tshuab ntawm cov hlau, ua rau nws tsim nyog rau ntau yam kev siv. Cov phaj hlau carbon tuaj yeem muab faib ua peb pawg raws li lawv cov pa roj carbon: hlau carbon qis (txog li 0.3% carbon), hlau carbon nruab nrab (0.3% txog 0.6% carbon), thiab hlau carbon siab (0.6% txog 2.0% carbon). Txhua qhov kev faib tawm muaj cov yam ntxwv sib txawv, ua rau lawv zoo tagnrho rau cov kev siv tshwj xeeb.
Cov yam ntxwv ntawm kev ua tau zoo ntawm Carbon Steel Phaj
Cov yam ntxwv ua tau zoo ntawm cov hlau carbon yog ib qho ntawm cov laj thawj tseem ceeb rau lawv siv dav. Cov hlau no muaj lub zog tensile zoo heev, ua rau lawv haum rau cov ntawv thov hnyav. Tsis tas li ntawd, cov hlau carbon paub txog lawv qhov kev vuam zoo thiab kev siv tshuab, ua rau yooj yim tsim thiab sib dhos. Lawv kuj muaj qib siab ntawm kev tawv, tshwj xeeb tshaj yog nyob rau hauv cov carbon siab, uas ua rau lawv tsis yooj yim hnav. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov hlau carbon muaj kev cuam tshuam rau xeb, uas yuav tsum tau muaj cov txheej tiv thaiv lossis kev kho mob hauv qee qhov chaw.
Cov Txheej Txheem Tsim Khoom ntawm Cov Hlau Carbon
Cov txheej txheem tsim cov phaj hlau carbon muaj ntau kauj ruam tseem ceeb. Thaum xub thawj, cov khoom siv raw, suav nrog cov hlau ore thiab cov hlau seem, raug yaj hauv lub cub tawg. Cov hlau molten ces raug ua kom huv si kom ua tiav cov ntsiab lus carbon thiab lwm yam khoom sib xyaw. Thaum ua tiav cov khoom sib xyaw xav tau, cov hlau raug pov rau hauv cov slabs, uas tom qab ntawd raug dov kub rau hauv cov phaj. Cov txheej txheem dov kub no tsis yog tsuas yog ua cov phaj xwb tab sis kuj txhim kho lawv cov khoom siv kho tshuab los ntawm kev tswj txias. Thaum kawg, cov phaj raug kuaj xyuas zoo kom ntseeg tau tias lawv ua tau raws li cov qauv kev lag luam ua ntej xa tawm ntawm peb lub Hoobkas phaj hlau carbon.
Phaj Hlau Carbon vs. Phaj Hlau Stainless
Txawm hais tias ob qho tib si cov hlau carbon thiab cov hlau stainless hlau siv dav hauv ntau yam lag luam, lawv muaj qhov sib txawv. Qhov sib txawv tseem ceeb yog nyob rau hauv lawv cov khoom sib xyaw; stainless hlau muaj tsawg kawg yog 10.5% chromium, uas muab kev tiv thaiv corrosion zoo heev. Hauv kev sib piv, cov hlau carbon tsis muaj cov ntsiab lus chromium no, ua rau lawv yooj yim xeb thiab corrosion. Txawm li cas los xij, cov hlau carbon feem ntau pheej yig dua thiab muaj zog dua, ua rau lawv yog qhov kev xaiv zoo rau cov ntawv thov kev tsim kho, cov khoom siv tsheb, thiab cov khoom siv tshuab.
Cov Kev Siv Feem Ntau ntawm Cov Phaj Hlau Carbon
Cov phaj hlau carbon siv rau ntau yam kev siv thoob plaws ntau yam lag luam. Lawv lub zog thiab kev ruaj khov ua rau lawv zoo tagnrho rau cov haujlwm tsim kho, suav nrog cov choj, cov tsev, thiab cov kav dej. Tsis tas li ntawd, lawv feem ntau siv rau hauv kev tsim cov tshuab hnyav, cov khoom siv tsheb, thiab kev tsim nkoj. Qhov ua tau ntau yam ntawm cov phaj hlau carbon kuj nthuav dav mus rau kev tsim cov thoob dej cia khoom, cov hlab siab, thiab ntau yam khoom siv hauv kev lag luam.
Xaus lus, Jindalai Steel Company tau cog lus tias yuav muab cov phaj hlau carbon zoo uas ua tau raws li ntau yam kev xav tau ntawm peb cov neeg siv khoom. Nrog peb cov kev txawj ntse ua tus tsim cov phaj hlau carbon, peb xyuas kom meej tias peb cov khoom raug tsim tawm raws li cov qauv siab tshaj plaws, muab kev ua tau zoo thiab kev ntseeg siab. Txawm hais tias koj xav tau cov phaj hlau carbon lossis cov phaj hlau carbon txheem, peb nyob ntawm no los txhawb koj qhov project nrog cov ntaub ntawv zoo tshaj plaws.
