Peb qhia dab tsi constructional steel

Kev siv ntawm steel tau ntev tau lug tuaj mus rau hauv peb lub neej thiab tsis ua kom muaj xav phem cais tsis nyob rau hauv nws cov expediency. Tiam sis peb yuav tsum tsis txhob hnov qab tias cov steel yuav txawv. Niaj hnub no tseem ceeb ob peb hom ntaub ntawv:

1. Lub Khoos Loos Tsev hlau.
2. Tool hlau.
3. Steel ib tug neeg lub hom phiaj nrog tshwj xeeb.

Wb tham hnub no hais txog tus yam ntxwv steels. Yog li ntawd hu ua tag nrho cov hom, uas yog siv nyob rau hauv qhuav ntawm tsev lug, raws li zoo raws li qhov chaw ntawm cov cav tov thiab mechanisms.

hom ntawm cov ntaub ntawv uas

Lub Khoos Loos Tsev steel yog muab faib ua ob pawg loj:

1. High-zoo yam ntxwv hlau.
2. High-zoo yam ntxwv carbon.

Tag nrho cov hom yog siv nyob rau hauv ib tug cheeb tsam ntawm ntau lawm, nqa tawm zog uas muab rau lawv.

Lub Khoos Loos Tsev alloyed steel

Heev feem ntau los txhim kho lub ua, lub cev thiab tshuaj thaj chaw ntawm lub zog ntxiv mus rau lub steel ntau yam hais, xws li nws yog doped. Feem ntau, rau cov hom phiaj, chromium, npib tsib xee, manganese. Lub Khoos Loos Tsev zoo steel tej zaum yuav muaj ib tug los yog ob peb xws ntsiab. Nyob rau hauv no hais txog, sawv tawm:

• Tsis tshua muaj hlau (tus xov tooj ntawm additives yog tsis ntau tshaj li 2.5%).
• Srednelegirovannye (daim duab tej zaum yuav sawv mus rau 10%).
• High alloyed (ntxiv hais ua ntau tshaj 10%).

Nyob rau hauv thiaj li yuav to taub yuav ua li cas khiav lag luam yog cov additive, nws yog tsim nyog los nkag siab txog cov muaj pes tsawg leeg ntawm cov khoom. Nws yog raws li ferrite (txog 90% los ntawm lub ntim). Lub alloying ntsiab yog yaj nyob rau hauv ferrite, li no kev txhim kho nws durability. Tshwj xeeb yog zoo nyob rau hauv no hais txog, pob zeb ntais, npib tsib xee thiab manganese. Tab sis chromium, tungsten thiab molybdenum muaj ib tug weaker nyhuv.

Nws yuav tsum tau muab sau tseg tias yam ntxwv hlau steel txawv uas tsis muaj weldability. Qhov no yog vim hardening ntawm lub tshav kub cuam tshuam cheeb tsam thiab tsim hauv nws ntawm lug uas yog lub cev tsis kho. Yog li ntawd, tshwj xeeb cov hom kev kawm uas yog siv nyob rau hauv lub vuam txoj kev, tsim ib lub zuj zus rau no hom ntawm hlau.

Tsis tshua muaj hlau ntxwv steel yog siv lug rau zus tau tej cov locomotives, phab xis thiab ua liaj ua teb machinery. Tag nrho cov khoom uas yog yus muaj los ntawm lawv muaj peev xwm los mus tiv nce mus nce los loads. weldability tsis ntawm no steel tsis muaj kev txwv.

Los ntawm cov high-hlau steel ua hniav thiab turbine rotors, reactors, kav chav kav thiab manifolds.

Carbon ntxwv Steel

Qhov thib ob hom yog sawv cev los ntawm ib yam nkaus thiab ob peb hom, xws li:

• Engineering. Lub Khoos Loos Tsev steel ntawm no zoo yog siv nyob rau hauv qhov siv thiab ua cov tsheb.
• Automaton. Nws yog vim hais tias ntawm no steel ua ntau yam fasteners. Nws yog nyob rau hauv tsis muaj txoj kev haum rau welding, tag nrho cov lus yog ua nyob rau hauv machine.
• Boiler chav tsev. Indispensable muaj, qhov twg nws tawm los rau qhov siv thiab ua boilers thiab cov hlab ntsha, uas muaj rau mas siab kub. Qhov no steel muaj zoo weldability.

Lub Khoos Loos Tsev steel - cov khoom, tsis muaj uas tus ntau lawm ntawm tej hom lug thiab Cheebtsam yog tsis tau.
