1. Cov txheej txheem no siv rau cov khoom siv carbon steel, cov qauv hlau rau lub nkoj hulls, thiab kub dov pob zeb diamond-puab, lentil-shaped, thiab puag ncig taum-zoo li tus qauv steel daim hlau uas muaj huab cua-resistant structural steel.
2. Cov qauv siv: Cov qauv coj mus kuaj rau kev tshuaj ntsuam xyuas ntawm GB222 steel thiab tso cai sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm cov khoom tiav, cov kev cai dav dav rau kev lees txais, ntim, cim thiab daim ntawv pov thawj zoo ntawm GB247 steel daim hlau thiab cov hlau strips. GB700 carbon structural steel GB709 kub dov steel daim hlau thiab strips loj, zoo li, hnyav thiab tso cai deviations GB712 qauv steel rau hull GB4171 siab huab cua tsis kam structural steel.
3. Qhov loj, zoo, qhov hnyav thiab qhov sib txawv ntawm cov hlau phaj 3.1 Qhov loj ntawm cov qauv steel phaj yuav tsum ua raws li cov kev cai hauv qab no: cov tuab tuab: 2.5, 3.0, 3.5, 4.{{1 0}}, 4.5, 5.0, 5.5, 6.{20}}, 7.0, 8.0mm. Dav: 600 ~ 1800mm, hloov kho raws li 50mm. Ntev: 2000 ~ 12000mm, hloov kho raws li 100mm. Raws li kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom, cov qauv steel daim hlau lossis cov ntawv dov qauv steel strips ntawm qhov ntau thiab tsawg uas tsis yog cov teev hauv cov qauv no tuaj yeem muab tau.
4. Qhov tso cai sib txawv ntawm qhov ntev thiab dav ntawm cov qauv steel phaj yuav tsum ua raws li cov kev cai ntawm GB709. Cov qauv steel daim hlau uas ua los ntawm cov rolling mills tas li tsis tas yuav raug txiav raws cov kab ntev ntev.
