Cov khoom siv dab tsi yog DC03 txias - rolled steel sib npaug rau?

1. Tus "DC" hauv DC01 sawv rau Din 1623 {}}}}} cov khoom txias ntawm steel steel txias-rolled sawb thiab daim ntawv. DC sawv rau din {{}}} cov khoom lag luam ntawm cov hlau; Cold Rolled Sawb thiab daim ntawv ntawm cov hlau tsis muaj me me. DC yog cov tsiaj ntawv luv rau cov hlau.

2. DC03 yog txias - rolled broup- cov hlau nrog cov qauv ua kom zoo dua qub thiab cuam tshuam. Nws yog dav siv nyob rau hauv kev tsim khoom ntawm cov khoom siv hauv tsev, chaw tsheb, thiab cov khoom siv hauv tsev. Hauv Suav teb, DC03 yog sib npaug rau cov khoom siv spcc, muab cov teeb meem zoo thiab zoo.

3. Ntxiv rau, txias - rolled steel, xws li}} {{{polled ntawv. Cov ob pawg no tau muaj vim muaj vim sib txawv ntawm cov duab thiab cov khoom siv. Ntawm chav kawm, vim muaj qhov sib txawv hauv cov chaw tsim khoom hlau, lub chaw tsim khoom lub npe qee zaum suav nrog lub npe.

4. Spcc {{{{1} s sawv rau hlau, p rau phaj, c rau kev lag luam - JId tus qauv JIS. Yuav kom lav tensile lub zog, ntxiv t txog qhov kawg ntawm qib, uas ua rau: SPCCT. Spcd - qhia tau txias- Cov ntawv stamping, sib npaug rau Tuam Tshoj tus txheej txheem 08A- zoo carbon qauv qauv hlau).

1. DC03 yog ib hom hlau. DC03 yog txias-} rolled steel feem ntau siv rau cov ntawv thov stamping, xws li cov khoom siv hluav taws xob thiab hluav taws xob. Cov lus piav qhia: p tsawg dua lossis sib npaug ntawm 030, s tsawg dua lossis sib npaug lossis sib luag ntau dua lossis sib npaug ntawm 270, elongation thaum tawg ntau dua lossis sib npaug rau 32.

2. DC03 smelting txoj kev: cov hlau siv rau cov phaj thiab cov hlua khi yog smelted nyob rau hauv ib tug oxygen hloov pa. DC03 daim ntaub ntawv: nws yog ib qho khoom siv rau stamping siab-} Cov khoom siv hluav taws xob, khav theeb lub zog loj thiab muaj zog. DCO3 kev xa khoom: tom qab dov tawm, daim hlau thiab cov ntawv xa tawm tau xa tom qab quenching, thiab flatening. Cov kev muaj mob tshwj xeeb yuav tsum tau hais hauv kev tiv thaiv.

3. SPCD sawv rau txias - rolled carbon steel ntawv thiab sawb rau Tuam Tshoj lub tshuab 08A (1323 High} Zoo roj teeb qauv hlau). Spce sawv rau cold - rolled carbon steel ntawv thiab sawb rau kev sib sib zog nqus duab, sib npaug rau Tuam Tshoj lub tshuab 08A).
