Cov thawv hlau hlau daim hlau, raws li ib hom tseem ceeb ntawm cov hlau khoom, tau siv dav hauv teb xws li kev tsim kho, kev tsim khoom lag luam, thiab txua tsheb. Txawm li cas los xij, ntau hom carbon hlau daim phiaj nthuav qhia qhov sib txawv ntawm cov tshuaj lom neeg, tshuab ua haujlwm, thiab cov ntawv thov siv tau. Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau kev xaiv kom raug thiab siv cov phiaj hlau siv roj carbon hlau.
Qhov sib txawv ntawm cov ntsiab lus carbon
Ib qho ntawm qhov sib txawv tseem ceeb hauv cov phiaj hlau siv roj carbon hlau yog lawv cov ntsiab lus carbon. Lawv feem ntau tau cais rau hauv peb pawg: cov hlau tsis tshua muaj carbon, nruab nrab cov pa roj carbon, thiab cov roj carbon hlau:
• Cov pa roj carbon tsawg (cov ntsiab lus carbon tsawg dua los yog sib npaug, thiab tsim kom haum rau kev tsim khoom, thiab muaj txiaj ntsig zoo, thiab txias {1} {tsim cov ntu. Vim nws lub zog qis, feem ntau yog siv rau hauv cov ntawv thov uas cov kev xav tau tsis xav tau.
• Nruab nruab nrab cov hlau (carbon cov ntsiab lus 0.25% cov ntsiab lus 0.25% -0.60%): Cov nta siab dua thiab hardness, tab sis tus neeg tsis zoo. Kev kho cua sov (xws li normalizing lossis quenching) feem ntau yuav tsum tau txhim kho nws cov khoom siv neeg. Nws yog feem ntau siv hauv kev tsim cov khoom siv tshuab xws li cov phuam, zog, thiab bolts.
• Cov pa roj carbon ntau (carbon cov ntsiab lus> 0.60%): nta tsis tshua muaj zog thiab hnav tsis muaj zog thiab nyuaj rau Weld. Nws yog feem ntau siv nyob rau hauv kev tsim khoom ntawm springs, txiav cov cuab yeej, thiab siab- Cov tawv tawv.
Kev faib tawm cov phaj steel hlau
Cov phiaj hlau hlau kuj tseem tuaj yeem raug faib los ntawm tuab rau hauv cov nyias nyias, nruab nrab, thiab tuab. Cov phaj tuab ntawm cov phaj hlau yog qhov haum rau cov kev xav tau tsim qauv sib xws:
• Cov paib nyias nyias (thickness tsawg dua los yog sib npaug rau 4mm): feem ntau siv rau stamping, khoov, thiab siv lub cev hluav taws xob thiab cov khoom siv hluav taws xob.
• Cov paib nruab nrab (tuab 4 --20mm): siv dav dav hauv tsev, txuas ntxiv, thiab lwm yam kev siv, xav tau cov khoom siv zoo tag nrho.
•Thick plates (thickness > 20mm): Suitable for high-load bearing structures, such as heavy machinery, ship decks, and high-rise buildings, typically requiring higher strength and toughness.
Qhov sib txawv hauv kev kho deg thiab qib zoo
Cov kev kho deg saum toj thiab cov qib zoo ntawm cov pa roj carbon steel kuj cuam tshuam nws daim ntawv thov:
• Kub {{- rolled steel phaj: Feem ntau muaj qhov sib zog, ua kom haum rau cov txheej txheem uas muaj nrog cov khoom siv tsawg dua.
• Txias - rolled steel phaj: Ua kom haum rau cov kev ua kom loog thiab qhov ntev, xws li cov vaj tse nyob hauv lub tsev thiab khoom siv.
• Galvanized Steel phaj: Galvanized rau kev ua kom corrosion zoo heev, nws feem ntau siv hauv tsev ru tsev, cov chaw cua, thiab cov qauv cua.
• Qib tau zoo (xws li Q235, Q345): Cov phiaj hlau roj av ntawm cov qib sib txawv thiab cov kev cuam tshuam nyuaj. Piv txwv li, Q235 yog qhov tsim nyog rau cov qauv dav dav, thaum q345 (qis {-}} all strength strength all}} Lub zog hlau) yog siv lub zog siab dua.
Sib txawv hauv cov ntawv thov
Ntau hom ntawm cov roj carbon steel yog tsim nyog rau kev lag luam sib txawv vim lawv sib txawv:
• Kev tsim kho: Cov paib tuab thiab Q235 thiab Q345 feem ntau yog siv rau cov qauv hlau, txuas hniav, thiab txhawb nqa pem teb, thiab txhawb nqa pem teb, thiab txhawb nqa pem teb, thiab txhawb nqa. •
Neeg kho tshuab tsim: nruab nrab-}} -} Cov hlau roj yog siv rau hauv cov zog, cov cuab yeej, thiab cov cuab yeej.
• Kev lag luam Automotive: Txias - rolled thiab galvanized steel los yog siv los txhim kho corrosion tsis kam thiab tsos.
• Nkoj: Cov paib tuab thiab siab {{0} {}} lub zog steel siv rau hauv cov txheej txheem nkoj ua kom ntseeg tau tias muaj kev cuam tshuam.

Cov phiaj xwm hlau sib txawv hauv cov ntsiab lus carbon ntau sib txawv hauv cov ntsiab lus carbon ntau, cov tshuaj tuab, thiab qib zoo uas cuam tshuam nrog lawv cov ntawv thov siv. Hauv kev siv cov tswv yim, cov ntaub ntawv pov thawj cov pa roj carbon hlau tsim nyog yuav tsum raug xaiv raws li cov cai kom ntseeg tau tias muaj kev nyab xeeb thiab raug nqi} ua hauj lwm zoo. To taub cov yam ntxwv sib txawv ntawm cov phiaj hlau carbon hlau tuaj yeem pab ua kom xaiv cov khoom zoo thiab txhim kho txoj haujlwm zoo thiab kev pabcuam lub neej.
