(1) Cov Lus Qhia Tshwj Xeeb: Cov ntsiab lus ntawm cov kav hlau kav yuav tsum tau teev nyob rau hauv daim ntawv cog lus kev lag luam ntshuam thiab xa tawm. Feem ntau, lawv yuav tsum suav nrog tus qauv hom (hom code), nominal txoj kab uas hla ntawm steel bar, nominal hnyav (ntau), teev ntev thiab kam rau ua tus nqi ntawm cov ntsuas saum toj no. Tuam Tshoj tus qauv pom zoo kom muaj cov kav hlau kav nrog nominal diameters ntawm 8, 10, 12, 16, 20 thiab 40 mm. Qhov ntev ntawm cov khoom muab faib ua qhov ntev thiab ntau qhov ntev. Qhov ntev xaiv ntau yam ntawm Suav exported rebar yog 6 mus rau 12 meters, thiab qhov ntev xaiv ntawm Japanese rebar yog 3.5 mus rau 10 meters.
(2) Cov tsos zoo:
① Nto zoo. Cov txheej txheem cuam tshuam tau teev tseg qhov zoo ntawm qhov chaw ntawm rebar, yuav tsum tau txiav kom ncaj, tsis muaj kab nrib pleb, nti thiab folds ntawm qhov chaw, thiab tsis muaj qhov tsis zoo uas tsim kev puas tsuaj rau kev siv;
② Tso cai tus nqi ntawm sab nraud qhov sib txawv. Cov kev cai rau qhov curvature ntawm rebar thiab geometric duab ntawm rebar yog teev nyob rau hauv cov qauv tsim. Raws li tau teev tseg nyob rau hauv Suav cov qauv, qhov curvature ntawm ncaj steel tuav yuav tsum tsis txhob ntau tshaj 6 mm / m, thiab tag nrho curvature yuav tsum tsis txhob ntau tshaj 0.6% ntawm tag nrho cov ntev ntawm cov hlau tuav.
