Hlau nrog ib tug hollow seem uas nws ntev yog ntau dua li nws txoj kab uas hla los yog ib ncig. Raws li tus ntoo khaub lig-sectional duab, nws muab faib ua round, square, rectangular thiab tshwj xeeb-zoo li tus steel kav; Raws li cov khoom siv, nws tau muab faib ua carbon structural steel yeeb nkab, qis alloy steel yeeb nkab, alloy steel yeeb nkab thiab cov yeeb nkab steel yeeb nkab; Raws li kev siv, nws tau muab faib ua cov kav dej thauj mus los, cov qauv tsim hluav taws xob, cov kav hlau steel rau cov khoom siv thermal, kev lag luam petrochemical, kev tsim cov tshuab, geological drilling, cov cuab yeej siv siab, thiab lwm yam .; Raws li cov txheej txheem ntau lawm, lawv tau muab faib ua seamless steel kav thiab welded steel kav, ntawm cov seamless steel kav muab faib ua kub dov thiab txias dov (kos) Muaj ob hom, welded steel kav yog muab faib ua ncaj seam welded. steel kav thiab kauv seam welded steel kav.
Cov kav hlau tsis yog tsuas yog siv los thauj cov kua dej thiab cov hmoov av, hloov hluav taws xob hluav taws xob, thiab tsim cov khoom siv tshuab thiab ntim khoom, tab sis lawv kuj yog ib hom kev lag luam hlau. Siv cov yeeb nkab steel los tsim cov txheej txheem hauv tsev, cov ncej thiab cov cuab yeej txhawb nqa tuaj yeem txo qhov hnyav, txuag 20 mus rau 40% ntawm cov hlau, thiab ua kom lub Hoobkas zoo li kev tsim kho tshuab. Kev siv cov yeeb nkab steel los tsim cov kev txuas hniav tuaj yeem tsis tsuas yog txuag cov hlau thiab ua kom yooj yim rau kev tsim kho, tab sis kuj txo qis thaj tsam ntawm kev tiv thaiv txheej, txuag peev thiab kev tu cov nqi.
(1) Specifications: Cov specifications ntawm kauv steel kav yuav tsum tau teev nyob rau hauv daim ntawv cog lus ntshuam thiab export kev lag luam. Feem ntau, nws yuav tsum suav nrog cov qauv qib (hom code), lub nominal txoj kab uas hla ntawm lub steel bar, nominal hnyav (ntau), qhov ntev ntev thiab qhov kam rau ua tus nqi ntawm cov kev ntsuas saum toj no, thiab lwm yam. Peb lub teb chaws tus qauv pom zoo ib tug series ntawm kauv. steel kav nrog nominal diameters ntawm 8, 10, 12, 16, 20, thiab 40mm. Qhov ntev ntawm cov khoom tau muab faib ua ob hom: qhov ntev ntev thiab ob qhov ntev. Qhov kev xaiv ntev ntev ntawm rebar xa tawm los ntawm kuv lub teb chaws yog 6 ~ 12m, thiab qhov kev xaiv ntev ntev ntawm rebar ua nyob rau hauv Nyiv yog 3.5 ~ 10m.
(2) Cov tsos zoo: ① Nto zoo. Cov txheej txheem tsim nyog tau teev tseg qhov zoo ntawm cov rebar, uas yuav tsum tau txiav kom ncaj, qhov saum npoo yuav tsum tsis muaj kab nrib pleb, nti, folds, thiab teeb meem kev siv; ② Tus nqi tso cai ntawm tag nrho qhov sib txawv. Cov kev cai rau qhov curvature ntawm rebar thiab geometry ntawm steel tuav yog teev nyob rau hauv cov qauv tsim. Raws li tau teev tseg nyob rau hauv peb lub teb chaws tus qauv, qhov curvature ntawm ncaj steel tuav yuav tsum tsis txhob ntau tshaj 6mm / m, thiab tag nrho cov curvature yuav tsum tsis txhob ntau tshaj 0.6% ntawm tag nrho cov ntev ntawm cov hlau tuav.
