Hauv ntiaj teb kev tsim hlau, qhov tseem ceeb ntawm cov hlau tooj dag tsis tuaj yeem hais ntau dhau. Ua tus thawj coj muag hlau tooj liab, Jindalai Steel Company tshwj xeeb hauv kev muab cov hlau tooj dag zoo, suav nrog C2680 hlau tooj dag, uas paub txog nws cov khoom siv zoo heev thiab kev hloov pauv tau yooj yim. Cov hlau tooj dag siv dav hauv ntau yam lag luam, los ntawm cov khoom siv hluav taws xob mus rau cov ntawv thov kho kom zoo nkauj, ua rau lawv yog cov khoom siv tseem ceeb hauv kev tsim khoom niaj hnub. Cov blog no lub hom phiaj yog tshawb nrhiav kev faib tawm cov khoom siv, cov txheej txheem tsim khoom, cov yam ntxwv, thiab cov txiaj ntsig ntawm kev siv cov hlau tooj dag, thaum tseem qhia txog lub luag haujlwm ntawm Jindalai Steel Company hauv qhov kev lag luam no.
Cov hlau tooj dag, suav nrog cov hlau tooj dag C2680, raug faib ua pawg raws li lawv cov tooj liab thiab zinc. Lub npe C2680 qhia txog cov khoom sib xyaw tshwj xeeb, uas feem ntau muaj kwv yees li 68% tooj liab thiab 32% zinc. Qhov kev faib tawm tshwj xeeb no paub txog nws qhov kev tiv thaiv corrosion zoo heev, kev siv tshuab zoo, thiab lub zog siab, ua rau nws haum rau ntau yam kev siv. Kev faib tawm cov khoom siv ntawm cov hlau tooj dag yog qhov tseem ceeb rau cov tuam ntxhab xaiv hom tooj dag zoo rau lawv cov kev xav tau tshwj xeeb, kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws hauv lawv cov khoom kawg.
Cov txheej txheem tsim cov hlau tooj dag muaj ntau kauj ruam tseem ceeb, pib nrog kev yaj cov khoom siv raw. Tooj liab thiab zinc raug yaj ua ke hauv lub cub tawg, tom qab ntawd pov cov hlau uas yaj rau hauv cov slabs. Cov slabs no ces raug dov kub kom ua tiav qhov tuab thiab dav uas xav tau. Tom qab dov kub, cov hlau tooj dag raug dov txias kom txhim kho lawv qhov tiav thiab qhov tseeb ntawm qhov ntev. Cov theem kawg ntawm kev tsim khoom yuav suav nrog kev annealing, uas yog cov txheej txheem kho cua sov uas txhim kho qhov ductility thiab kev ua haujlwm ntawm cov hlau tooj dag. Jindalai Steel Company siv cov thev naus laus zis zoo tshaj plaws thiab cov kev ntsuas tswj hwm zoo thoob plaws hauv cov txheej txheem tsim khoom no kom ntseeg tau tias lawv cov hlau tooj dag ua tau raws li cov qauv kev lag luam.
Cov yam ntxwv ntawm cov tooj dag, tshwj xeeb tshaj yog C2680 tooj dag, ua rau lawv nrhiav tau ntau hauv ntau yam kev siv. Cov tooj dag qhia tau tias muaj hluav taws xob zoo heev, ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob thiab cov khoom sib txuas. Tsis tas li ntawd, lawv txoj kev tiv thaiv corrosion tso cai rau lawv siv rau hauv cov kav dej thiab cov ntawv thov hauv dej hiav txwv, qhov twg raug dej noo thiab qhov chaw ib puag ncig hnyav yog qhov tshwm sim. Daim ntawv thov ntawm cov tooj dag txuas mus rau kev lag luam tsheb, qhov twg lawv siv rau hauv kev tsim khoom xws li radiators thiab fittings. Qhov ua tau ntau yam ntawm cov tooj dag yog ib qho pov thawj rau lawv qhov tseem ceeb hauv kev tsim khoom niaj hnub.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov hlau tooj dag, tshwj xeeb tshaj yog cov uas Jindalai Steel Company muab, yog lawv lub peev xwm yooj yim ua thiab tsim ua cov duab nyuaj. Cov yam ntxwv no tso cai rau cov chaw tsim khoom tsim cov qauv tsim tsis muaj kev cuam tshuam rau kev ncaj ncees ntawm cov khoom siv. Ntxiv mus, cov lus qhia txog kev kho cua sov rau cov hlau tooj dag tuaj yeem hloov kho kom txhim kho cov yam ntxwv tshwj xeeb, xws li qhov nyuaj lossis ductility, nyob ntawm seb daim ntawv thov xav tau. Qhov kev hloov pauv no ua rau cov hlau tooj dag yog qhov kev xaiv zoo rau cov engineers thiab cov neeg tsim qauv uas tab tom nrhiav cov ntaub ntawv txhim khu kev qha uas tuaj yeem ua tau raws li ntau yam kev xav tau.
Xaus lus, cov hlau tooj dag, tshwj xeeb tshaj yog cov hlau tooj dag C2680, ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam vim lawv cov khoom tshwj xeeb thiab kev hloov pauv tau yooj yim. Lub Tuam Txhab Jindalai Steel sawv tawm ua tus neeg muab khoom siv hlau tooj dag uas muaj npe nrov, cog lus tias yuav xa cov hlau tooj dag zoo uas ua tau raws li qhov xav tau ntawm kev tsim khoom niaj hnub. Los ntawm kev nkag siab txog kev faib tawm cov khoom siv, cov txheej txheem tsim khoom, cov yam ntxwv, thiab cov txiaj ntsig ntawm kev siv cov hlau tooj dag, cov chaw tsim khoom tuaj yeem txiav txim siab tau zoo uas txhim kho lawv cov khoom muag thiab tsav kev tsim kho tshiab hauv lawv cov teb.
