Raws li ib qho tseem ceeb ntawm cov khoom siv hlau, cov kav hlau steel tau muab faib ua ob pawg: seamless steel yeeb nkab (round) thiab welded steel yeeb nkab (board, band) vim yog cov txheej txheem tsim khoom sib txawv thiab cov duab ntawm cov kav dej siv.
1. Txias-rolled molding steel tso cai rau hauv zos flexion kom muaj lub zos flexion, kom cov kabmob muaj peev xwm tom qab tus ncej yog flexed; thaum lub kub-kuav los tiag steel tsis cia lub zos flexion tshwm sim nyob rau hauv tus ntoo khaub lig seem.
2. Qhov ua rau kub-kuav los tiag steel thiab txias-dov steel residual kev ntxhov siab yog txawv, yog li qhov kev faib tawm ntawm qhov hla ntu kuj txawv heev. Qhov seem kev ntxhov siab faib rau ntawm qhov txias-curved nyias phab ntsa yog khoov, thaum seem kev ntxhov siab faib ntawm cov hlau kub-dov los yog welded steel seem yog ib hom yeeb yaj kiab nyias.
Tsis muaj ntau qhov sib txawv ntawm ob lub kav hlau steel hauv cov khoom tiav. Feem ntau, lawv raug tsim raws li cov qauv. Tsis muaj qhov sib txawv ntawm cov khoom siv kho tshuab. Siab dua.
Lub welded steel yeeb nkab kuj hu ua welded yeeb nkab. Nws yog cov yeeb nkab steel ua los ntawm steel phaj lossis steel siv thiab welded tom qab curling. Vuam steel yeeb nkab ntau lawm tshuab yog yooj yim, siab ntau lawm efficiency, ntau ntau yam thiab specifications, thiab cov khoom me me nyiaj txiag, tab sis feem ntau qis dua seamless steel kav.
welding steel yeeb nkab yog muab faib ua ncaj seam welded kav thiab kauv welded kav nyob rau hauv daim ntawv ntawm welds. Lub zog ntawm cov kauv raj feem ntau yog siab tshaj qhov ncaj seam welded yeeb nkab. Nws tuaj yeem siv cov yeeb nkab welded nrog ib txoj kab uas hla loj dua nrog cov khoom siv nqaim. Nws tseem tuaj yeem siv cov kav dej sib txawv uas muaj qhov sib txawv ntawm qhov sib txawv ntawm cov yeeb nkab diameters ntawm tib qhov dav. Txawm li cas los xij, piv nrog tib qhov ntev ntawm tib qhov ntev, qhov ntev ntawm qhov vuam yog nce los ntawm 30 ~ 100%, thiab qhov ceev ntau lawm yog qis dua. Yog li ntawd, feem ntau ntawm cov me me-caliber welded kav yog welded nrog ncaj seams, thiab feem ntau ntawm cov loj-caliber welded kav yog feem ntau muab kauv welded.
