Raws li cov khoom siv uas siv tau rau cov hlaukho saum npoo, hlau txhajkuj yog nyob rau hauv

kev xav tau loj hauv kev lag luam.Ob peb xyoos dhau los nrog kev txhim kho txuas ntxiv ntawm domestic

steel txhaj tshuaj ntau lawm qhauj, tus nqi ntawm steel txhaj tshuaj kuj yog nyob rau hauv lub xyoo poob los ntawm

xyoo, tab sis qhov kev siv tau nthuav dav, cov nyiaj tau nce xyoo los ntawm xyoo.

Ob peb xyoos dhau los vim yog Tuam Tshoj tus nqi hlau tau nce, raws li cov khoom tseem ceeb ntawm cov hlau

txhaj tshuaj,seem hlaucov nqi tau nce, tab sis nyob rau yav tom ntej, steel nqi poob qis

dua, tus nqi muag ntawm cov hlau txhaj tshuaj kuj poob, yog li tsim cov khoom siv raw khoom, tab sis

muag cov khoom tiav ua lag luam qauv, yog cov hlau dav dav tua cov chaw tsim khoom cov nyiaj tau los

margin txhua txoj kev.Vim ib co manufacturers ntawm qhov muag tsis pom kev, ua rau ib tug

ntau qhov kev ntsuas tsis nyob hauv qhov chaw, steel txhaj tshuaj zoo tsis tau lees paub zoo,

hlau txhajkev lag luam ib zaug tshwm sim sib xyaw.Tab sis nrog kev rov qab sai thiab

txoj kev loj hlob ntawm cov hlau txhaj tshuaj ua lag luam nyob rau hauv xyoo tas los no.

Nyob rau hauv xyoo tas los no, Tuam Tshoj txoj kev lag luam sai sai, kev lag luam hlau txhaj tshuaj maj mam

tau tsav, kev lag luam zeem muag zoo.

Kev txhaj tshuaj hlau yog ib hom hlau uas feem ntau sivworkpiece kho cov ntaub ntawv, steel txhaj yog

nruj nreem kaw, uniform particle loj, siv hlau txhaj tshuaj los kho qhov nto ntawm hlau

workpiece tuaj yeem ua lub luag haujlwm hauv kev nce qhov siab ntawm cov hlau workpiece, tuaj yeem

zoo heev txhim kho lub peev xwm los tiv thaiv kev qaug zog ntawm lub workpiece.Kev siv cov hlau txhaj tshuaj

ua hlau workpiece nto muaj cov yam ntxwv ntawm kev ceev ceev ceev, steel

tua thiabsteel xuab zebmuaj qhov tsim nyog hardness, nrog zoo resilience, internal ces kaum thiab

complex duab ntawm lub workpiece yuav ua tau ib yam nkaus thiab ceev tu, shorten lub sij hawm ntawm

Kev kho deg, txhim kho kev ua haujlwm zoo, yog cov khoom siv kho mob zoo.

Hlau txhaj tshuaj yog cov khoom siv kho mob saum npoo av, muaj ntau hom kev txhaj tshuaj steel, rau

ntau hom kev txhaj tshuaj steel, cov khoom siv raw thiab cov khoom siv tsis zoo ib yam.Cov

Hauv qab no yog cov yam ntxwv tseem ceeb ntawm kev txhaj tshuaj steel:

Hlau txhaj tshuaj yog ib yam khoom zoo hnav-tiv taus.Nws muaj nruab nrab hardness,

muaj zog toughness, zoo cuam tshuam tsis kam thiab kev pab lub neej ntev.Thaum ntxuav lub

workpiece, nws muaj zoo resilience, ceev ceev ceev thiab noj tsawg.Steel txhaj yog

dav siv, xws li casting, forgings, machining qhov chaw nto thiab qhov chaw tom qab tshav kub

kev kho mob ntawm qhov chaw thiab lwm qhov chaw.Kev txhaj tshuaj steel yog siv dav hauv kev tsim khoom,

nkoj tsim, thiab lwm yam.
