Dab tsi yog txias - rolled steel ntawv?
I. Kev txhais thiab tsim cov txheej txheem ntawm txias - rolled steel ntawv
Txias -} rolled steel ntawv yog tsim los ntawm txias- rolling kub- rolled steel ntawv ntawm chav tsev kub. Piv rau kub - rolled steel ntawv, txias} cov khoom siv hlau muaj cov khoom siv hlau zoo dua, thiab tsis tshua muaj neeg siv zog ua kom tsis zoo. Txias {{{}} rolled steel ntawv yog feem ntau ua los ntawm ntau yam steel, siab}} {{{{11 {{{{}} tiv taus hlau. Cov txheej txheem tsim khoom muaj xws li cov kauj ruam, suav nrog cov khoom siv xaiv, kub yob, ua kom txias, txias, thiab xeb- ua pov thawj.
Ii. Cov yam ntxwv ntawm cold - rolled steel ntawv
1. Lub ntsej muag siab tiav: txias-}} rolled steel ntawv kev kho mob, ua rau muaj kev sib txawv ntawm qhov tsis huv thiab oxidation.
2. Cov cuab yeej siv tau ruaj khov: txias- Rolled cov ntawv txheej txheem zoo heev xws li lub zog, kev ua tau zoo, kev ua tau zoo, thiab ductility.
3. Lub siab nyob sab nraud: txias-}} rolled steel ntawv muab cov ntawv siab siab, sib ntsib ntau yam kev tsim khoom.
4. Cov txheej txheem zoo: txias - rolled steel ntawv yog yooj yim ua tiav rau hauv ntau daim teb thiab tau siv dav hauv ntau thaj teb.
III. Cov ntawv thov ntawm txias - rolled steel ntawv
Txias - rolled steel ntawv yog dav siv nyob rau hauv Automotive, cov khoom siv hauv tsev, tsim khoom siv hauv tsev, thiab machinery manufacturation kev lag luam. Qhov chaw siv tsheb yog qhov loj tshaj daim ntawv thov thaj chaw rau txias- rolled steel ntawv, accounting rau ze li 50% ntawm tag nrho cov kev thov. Txias - rolled steel ntawv yog siv nyob rau hauv kev tsim khoom lag luam xws li lub zog, thiab lub zog siab, thiab lub teeb nyuaj heev. Hauv cov khoom siv hauv tsev, txias {{{polled steel ntawv yog feem ntau siv los tsim cov khoom siv sab nrauv thiab sab hauv thiab tshuab ntxhua khaub ncaws, thiab ntxhua khaub ncaws. Hauv lub tsev cov ntaub ntawv sector, cold- Rolled steel ntawv yog feem ntau siv los tsim cov khoom siv vov, thiab cov vov tsev.
Nrhiav tau nyob rau xyoo 2008,Gnee steelUa cov khaub thuas - rolled steel ntawv, dav siv steel khoom nrog zoo heev nto moo zoo thiab cov kws kho tshuab, haum rau ntau cov ntawv thov.
