Kub dov kauj
Cov hlau kub dov yog ib yam khoom siv tseem ceeb hauv kev lag luam hlau. Nws yog ua los ntawm kev dov kub siab thiab muaj cov yam ntxwv ntawm tus nqi qis, lub zog siab, thiab kev ua haujlwm zoo. Nws yog siv dav hauv kev tsim kho, tshuab, tsheb, nkoj thiab lwm yam teb.
Kev txhais yooj yim
Cov kauj hlau kub dov (HRC) yog hais txog cov khoom hlau uas raug dov tas li saum qhov kub recrystallization (feem ntau> 900 ° C) los ntawm billets (xws li slabs lossis billets) thiab thaum kawg curled.
Qhov sib txawv ntawm cov kauj vuam txias: Cov kauj vuam kub tsis yog dov txias, qhov saum npoo yog ntxhib, qhov tseeb ntawm qhov ntev yog qis, tab sis lub zog yog siab thiab qhov ductility zoo, uas yog qhov tsim nyog rau kev tsim cov khoom siv.
Cov yam ntxwv tseem ceeb
| Cov yam ntxwv | Kub dov kauj | Txias dov kauj |
| Cov txheej txheem ntau lawm | Kev dov kub siab (> 900 ° C) | Kev dov kub ib txwm (kev ua txias) |
| Qhov zoo ntawm qhov chaw | Oxide nplai, ntxhib | Du, siab precision |
| Lub zog | Qis (tab sis muaj zog zoo) | Siab (ua haujlwm kom ruaj khov) |
| Tus nqi | Qis | Siab |
| Cov ntawv thov | Cov khoom siv hauv tsev, cov kav dej, cov thav tsheb | Cov khoom siv precision, cov khoom siv hauv tsev, cov vaj huam sib luag tsheb |
3. Cov txheej txheem tsim khoom
Cua sov: Cov hlau billet yog cua sov rau 1100 ~ 1250 ° C kom nws mos.
Kev dov tsis sib xws: Kev tsim ua ntej los ntawm lub tshuab dov siab.
Kev dov tiav: Tswj qhov tuab rau qhov loj me (xws li 1.2 ~ 20 hli).
Coiling: Tom qab dov, nws yog dov rau hauv ib lub kauj hlau (feem ntau 1 ~ 2 meters hauv lub cheeb sab nraud).
Kev Txias: Kev txias ntuj lossis kev txias tswj tau (xws li cov txheej txheem TMCP).
Cov lus qhia dav dav
Thickness: 1.2 ~ 25mm (feem ntau 2.0 ~ 6.0mm).
Dav: 600 ~ 2200mm (feem ntau 1250mm, 1500mm).
Khoom siv: Q235B (cov hlau carbon dawb), SS400 (tus qauv Nyiv), A36 (tus qauv Asmeskas), S355JR (tus qauv European).
Cov khoom siv kho tshuab: lub zog tensile 300 ~ 500MPa, cov zis muaj zog 200 ~ 400MPa.
Cov chaw thov tseem ceeb
Kev lag luam tsim kho: H-beam, steel qauv, choj, steel bar.
Kev tsim khoom siv: tshuab engineering, cov khoom siv mining, lub nkoj siab.
Kev lag luam tsheb: thav duab, lub log hub, chassis qauv.
Kev lag luam pipeline: welded yeeb nkab, kauv yeeb nkab (xws li API 5L pipeline steel).
Kev lag luam nkoj: nkoj phaj, bulkhead qauv.
Lub tuam txhab muab qhov tseem ceeb rau qhov zoo ntawm cov khoom, nqis peev ntau rau kev qhia txog cov cuab yeej siv siab heev thiab cov kws tshaj lij, thiab mus txhua yam kom tau raws li qhov xav tau ntawm cov neeg siv khoom hauv tsev thiab txawv teb chaws.
Cov ntsiab lus tuaj yeem muab faib ua: tshuaj lom neeg muaj pes tsawg leeg, lub zog tawm los, lub zog tensile, cov khoom cuam tshuam, thiab lwm yam
Tib lub sijhawm, lub tuam txhab kuj tseem tuaj yeem ua qhov kev tshawb pom qhov tsis zoo hauv online thiab annealing thiab lwm yam txheej txheem kho cua sov raws li cov neeg siv khoom xav tau.
